Consolidated TEXT: 31997L0027 — EN — 15.04.2003

DIRECTIVE 97/27/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL

of 22 July 1997

relating to the masses and dimensions of certain categories of motor vehicles and their trailers and amending Directive 70/156/EEC



THE EUROPEAN PARLIAMENT AND THE COUNCIL OF THE EUROPEAN UNION,

Having regard to the Treaty establishing the European Community, and in particular Article 100a thereof,

Having regard to the proposal from the Commission ( 1 ),

Having regard to the opinion of the Economic and Social Committee ( 2 ),

Acting in accordance with the procedure laid down in Article 189b of the Treaty ( 3 ),

(1)

Whereas the total harmonization of technical requirements for motor vehicles is necessary in order to achieve the smooth functioning of the internal market, while ensuring a high level of safety for the public;

(2)

Whereas the technical requirements which certain vehicle categories must satisfy pursuant to national laws relate, inter alia, to their masses and dimensions;

(3)

Whereas these requirements differ from one Member State to another; whereas it is therefore necessary that all Member States adopt the same requirements either in addition to or in place of their existing rules in order to allow, in particular, the EC type-approval procedure which was the subject of Council Directive 70/156/EEC of 6 February 1970 on the approximation of the laws of the Member States relating to the type-approval of motor vehicles and their trailers ( 4 ), to be applied in respect of each type of vehicle;

(4)

Whereas it is desirable to harmonize the maximum masses and dimensions of motor vehicles and their trailers to be registered in the Member States in accordance with Directive 96/53/EC of 25 July 1996 laying down, for certain road vehicles circulating within the Community, the maximum authorized dimensions in national and international traffic and the maximum authorized weights in international traffic ( 5 ); whereas the aforementioned Directive applies only to the traffic on the territories of the Member States and not to technical requirements as laid down in Directive 70/156/EEC;

(5)

Whereas Directive 96/53/EC lays down certain maximum authorized dimensions for both national and international traffic in the Member States with a certain lead time for their entry into force; whereas some other maximum authorized dimensions, as well as maximum authorized masses, remain applicable only to international traffic;

(6)

Whereas, as a consequence, the harmonization of the maximum authorized masses of motor vehicles and their trailers to be registered in the Member States does not appear to be feasible in the short term; whereas on the other hand it does now appear feasible to achieve, as far as possible, the harmonization of their maximum dimensions, to deal with the question of masses by providing for the possibility of a uniform procedure to determine the registration/in-service maximum permissible masses of vehicles in each Member State, and to pursue the constant improvement of safety, in particular with regard to certain categories of trailers;

(7)

Whereas, according to Article 4 (3) and (4) of Directive 96/53/EC, Member States may allow the circulation on their territory of category N vehicles with dimensions exceeding the limits laid down in that Directive, either for the carriage of indivisible loads or for the purpose of certain national transport operations that do not significantly affect international competition in the transport sector; whereas, as far as category M2 and M3 vehicles are concerned, Directive 96/53/EC applies only to international traffic; whereas it is therefore necessary by way of derogation to allow approvals for vehicles of dimensions exceeding the maximum dimensions authorized by this Directive and for certain other characteristics, together with the possibility for Member States to refuse vehicles approved under those derogating provisions;

(8)

Whereas this Directive is one of the separate directives which must be complied with in order to ensure the conformity of vehicles with the requirements of the EC type-approval procedure established by Directive 70/156/EEC; whereas, consequently, the provisions laid down in Directive 70/156/EEC relating to vehicle systems, components and separate technical units apply to this Directive;

(9)

Whereas, in particular, pursuant to Articles 3 (4) and 4 (3) of Directive 70/156/EEC, each separate directive must have attached to it an information document incorporating the relevant items of Annex I to that Directive and also a type-approval certificate based on Annex VI thereto so that type-approval can be computerized;

(10)

Whereas special provisions have been incorporated as regards incomplete vehicles in order to facilitate second-stage approval of completed vehicles;

(11)

Whereas special provisions are introduced in this Directive to take account of retractable or loadable axles; whereas it is acknowledged that such axles should also be taken into account in Council Directive 71/320/EEC of 26 July 1971 on the approximation of the laws of the Member States relating to the braking devices of certain categories of motor vehicles and of their trailers ( 6 ) and in Council Directive 70/311/EEC of 8 June 1970 on the approximation of the laws of the Member States relating to steering equipment for motor vehicles and their trailers ( 7 );

(12)

Whereas special provisions should also be incorporated into Directive 71/320/EEC in order to take better account of the technical conditions under which vehicles of categories M2, M3 and N may tow trailers;

(13)

Whereas special provisions should also be incorporated into Council Directive 76/114/EEC of 18 December 1975 on the approximation of the laws of the Member States relating to statutory plates and inscriptions for motor vehicles and their trailers, and their location and method of attachment ( 8 ) to take account of the fact that vehicles may be registered at different masses in the Member States,

HAVE ADOPTED THIS DIRECTIVE:



Article 1

For the purposes of this Directive, ‘vehicle’ means any motor vehicle or trailer as defined in Article 2 of and Annex II to Directive 70/156/EEC, with the exception of vehicles of category M1.

Article 2

No Member State may refuse to grant EC type-approval or national type-approval of a vehicle type, or refuse or prohibit the sale, registration, entry into service or use of a vehicle on grounds relating to its masses and dimensions if these satisfy the requirements set out in Annex I hereto.

Article 3

However, a Member State may refuse to grant national type-approval of a vehicle type, or refuse or prohibit the sale, registration, entry into service or use of a vehicle, or consider its certificate of conformity as not valid within the meaning of Article 7 (1) of Directive 70/156/EEC, or authorize it only for the carriage of indivisible loads if, having been granted approval under this Directive, it benefits from the derogation provided for in Article 7 thereof and that derogation conflicts with the national requirements in force in that Member State.

Article 4

When Member States grant national type-approval of vehicles approved under this Directive or permit the registration, entry into service or use of such vehicles, they assign to them national registration/in-service maximum permissible masses according to their relevant national maximum authorized masses. For the determination of these registration/in-service maximum permissible masses, no Member State may refuse to apply the procedure provided for in Annex IV, should the manufacturer request its application.

Article 5

By way of derogation from Article 2, Member States may submit loadable and retractable axles to national technical requirements. However, no Member State may refuse to apply the technical requirements laid down in section 3 of Annex IV should the manufacturer request their application.

Article 6

By way of derogation from Article 2 and section 7.3.2.1 of Annex I, Member States may refuse to grant national type-approval of, or refuse or prohibit the sale, registration or entry into service or use of buses or coaches the width of which exceeds 2,50 m until 31 December 1999, as provided by Article 9 of Directive 96/53/EC.

Article 7

By way of derogation from Article 2 and section 7.3 of Annex I, and without the requirements of section 7.6 of Annex I having to be fulfilled, Member States may approve vehicles with dimensions exceeding those laid down in those sections. Details of the derogation shall be included in the type-approval certificate in Annex III to this Directive and the provisions of Article 3 shall apply.

7.4.1.   Calculation procedure

7.4.1.1.

For the purpose of the mass distribution calculations hereafter laid down, the manufacturer must provide the technical service in charge of the tests with the information (in tabular or any other appropriate form) necessary to identify — for each technical configuration within the vehicle type as defined by each set of the possible values of all the items in Annex II to this Directive — the corresponding technically permissible maximum laden mass of the vehicle, the technically permissible maximum masses on the axles and groups of axles, the technically permissible maximum towable mass, and the technically permissible maximum laden mass of the combination.

7.4.1.2.

Suitable calculations must be carried out in order to make sure that the following requirements are fulfilled for each technical configuration within the type. For this purpose, the calculations may be limited to the worst cases.

7.4.1.3.

In the following requirements, the notations M, mi, µj, TM, and MC respectively designate the following parameters, for which the requirements of 7.4 must be fulfilled:

M = the technically permissible maximum laden mass of the vehicle,

mi = the technically permissible maximum mass on the axle designated ‘i’, where ‘i’ varies from 1 to the total number of axles of the vehicle,

µj = the technically permissible maximum mass on the solo axle or group of axles designated ‘j’, where ‘j’ varies from 1 to the total number of solo axles and groups of axles,

TM = the technically permissible maximum towable mass, and

MC = the technically permissible maximum laden mass of the combination.

7.4.1.4.

In the case of a solo axle, designated ‘i’ as an axle and ‘j’ as a group of axles, mi = µj by definition.

7.4.1.5.

In the case of vehicles fitted with loadable axles, the following calculations must be carried out with the suspension of the axles loaded in the normal running configuration. In the case of vehicles fitted with retractable axles, the following calculations are carried out with the axles lowered.

7.4.1.6.

For groups of axles, the manufacturer must indicate the laws of distribution among the axles of the total mass applied on to the group (for instance by stating the distribution formulae or producing distribution graphs).

7.4.1.7.

In the case of semi-trailers and centre-axle trailers, and for the purpose of the following calculations, the coupling point is considered as an axle designated ‘O’, and the corresponding masses mo and µo defined, by convention, as the technically permissible maximum mass on the coupling point of the trailer.

7.4.2.   Requirements for vehicles of categories N and O, except trailer caravans

7.4.2.1.

The sum of the masses mimust not be less than the mass M.

7.4.2.2.

For each group of axles designated ‘j’, the sum of the masses mi on its axles must not be less than the mass µj. In addition, each of the masses mi must not be less than the part of µj applying on the axle ‘i’ as determined by the mass distribution laws for that group of axles.

7.4.2.3.

The sum of the masses µjmust not be less than the mass M.

7.4.2.4.

The mass in running order, plus the mass corresponding to 75 kg multiplied by the number of passengers, plus the technically permissible maximum mass on the coupling point, must not exceed the mass M.

7.4.2.5.

When the vehicle is laden to its mass M according to any one of the relevant situations described in sections 7.4.2.5.1 or 7.4.2.5.2 the mass corresponding to the load on the axle ‘i’ must not exceed the mass Mi on that axle, and the mass corresponding to the load on the solo axle or group of axles ‘j’ must not exceed the mass μj.

7.4.2.5.1.

Uniform distribution of mass means the vehicle in running order with a mass of 75 kg positioned on every passenger seat is laden to its mass M, the payload being uniformly distributed on the area designed for the transportation of goods.

7.4.2.5.2.

In the case of extreme distribution of mass (non-uniform load), the manufacturer must state the extreme permissible possible positions of the centre of gravity of the payload and/or body and/or equipment or interior fittings (for instance: from 0,50 m to 1,30 m in front of the first rear axle), with the vehicle in running order and a mass of 75 kg positioned on every passenger seat being laden to its mass M.

7.4.2.6.

When a vehicle of category N is laden to its mass M and its rear axle (designated ‘n’ as an axle) or rear group of axles (designated ‘q’ as a group of axles) is laden to its mass mn or µq, the mass bearing on the steering axle or axles must not be less than 20 % of M.

7.4.2.7.

MC must not exceed M + TM.

7.4.3.   Requirements for buses and coaches

7.4.3.1.

The requirements of 7.4.2.1 to 7.4.2.3, and of 7.4.2.7, apply.
7.4.3.2.

The mass of the vehicle in running order, plus the mass Q multiplied by the number of seated and standing passengers, plus the masses WP, B and BX as defined in section 7.4.3.3.1, plus the technical permissible maximum mass on the coupling point, if a coupling is fitted by the manufacturer, shall not exceed the mass M.

7.4.3.3.

When the incomplete vehicle is laden to its mass M according to the situation described in 7.4.2.5.1.2 or when the complete or completed vehicle in running order is laden as described in 7.4.3.3.1 the mass corresponding to the load on each axle must not exceed the mass mi on each axle, and the mass corresponding to the load on each solo axle or group of axles must not exceed the mass µj on that group of axles. Moreover, the mass corresponding to the load on the driving axle or the sum of masses corresponding to the loads on the driving axles must be a least 25 % of M.

7.4.3.3.1.

The vehicle in running order is loaded with: a mass corresponding to the number P of seated passengers, of mass Q; a mass corresponding to the number SP of standing passengers, of mass Q uniformly distributed over the surface available for standing passengers S1; where appropriate, a mass WP uniformly distributed over each wheelchair space; a mass equal to B (kg) uniformly distributed in the baggage compartments; a mass equal to BX (kg) uniformly distributed over the surface area of the roof equipped for the carriage of baggage, where:

P is the number of seating places.

S1 is the area for standing passengers. In the case of vehicles of classes III or B, S1 = 0.

SP, declared by the manufacturer, must not exceed the value S1/Ssp, where Ssp is the conventional space provided for one standing passenger specified in the table below.

WP (kg), is the number of wheelchair spaces multiplied by 250 kg representing the mass of a wheelchair and user.

B (kg), declared by the manufacturer, must have a numeric value not less than 100 × V. This shall include baggage compartments or racks that may be attached to the outside of the vehicle.

V is the total volume of baggage compartments in m3. When approving a vehicle of Class I or A, the volume of baggage compartments accessible only from the outside of the vehicle shall be disregarded.

BX, declared by the manufacturer, must have a numeric value not less than 75 kg/m2. Double deck vehicles shall not be equipped for the carriage of baggage on the roof and therefore BX for double deck vehicles shall be zero.

Q and Ssp have values laid down in the following table:

7.4.4.   Requirements for trailer caravans

The requirements of 7.4.2.1 to 7.4.2.4 and of 7.4.2.7 apply. In addition, when the incomplete vehicle is laden to its mass M according to the situation described in 7.4.2.5.1.2, or when the complete or completed vehicle in running order is laden to its mass M as described in the Appendix to Annex II to Council Directive 92/21/EEC ( 10 ), the mass corresponding to the load on each axle must not exceed the mass mi on this axle, and the mass corresponding to the load on each solo axle or on the group of axles must not exceed the mass µj on this group of axles. Moreover, the mass corresponding to the load on the driving axle or the sum of the masses corresponding to the loads on the driving axles must be at least 25 % of M.

7.5.   Conditions to be verified for the classification of a vehicle as an off-road vehicle (Annex II, section 4 of Directive 70/156/EEC)

7.5.1.

The technical service must verify if the complete or completed vehicle, or the semi-trailer towing vehicle (semi-trailer tractor) without fifth wheel is to be considered as an off-road vehicle according to the requirements laid down in Annex II to Directive 70/156/EEC.

7.5.2.

For other incomplete vehicles, this verification is carried out only at the request of the manufacturer.

7.6.   Manoeuvrability

7.6.1.

Any motor vehicle and any semi-trailer must be able to manoeuvre on either side for a complete circular trajectory of 360 ° inside an area defined by two concentric circles, the outer circle having a radius of 12,50 m and the inner circle having a radius of 5,30 m, without any of the vehicle's outermost points (with the exception of the protruding parts prescribed for the vehicle width in 2.4.2) projecting outside the circumferences of the circles.

For motor vehicles and semi-trailers with axle-lift devices (see section 2.14), this requirement also applies with the retractable axle(s) in the lifted position or loadable axle(s) in the unladen condition. Starting aids such as retractable axles fulfilling the requirements of section 3.5 of Annex IV are exempt from this requirement.

The abovementioned requirements must be verified as follows:

7.6.1.1.   Motor vehicles

The outermost front point of the motor vehicle must be guided along the contour of the outer circle (see figure A).

7.6.1.2.   Semi-trailers

A semi-trailer is deemed to comply with the requirements of 7.6.1 if its wheelbase is not greater than 212,50−2,042−5,30+L/22

where L is the semi-trailer's width, the wheelbase being measured for the purpose of this section as the distance of the axis of the semi-trailer fifth wheel king-pin to the centre line of the non-steering bogie axles; if one or more of the non-steering bogie axles has an axle lift device (see 2.14), then the wheelbase with lowered/lifted axle(s), whichever is the longer, is taken into account. In case of doubt, the approval authority can require a test to be carried out as described at 7.6.1.

7.6.2.   Additional requirements for vehicles of category N

When the vehicle is stationary and has its steered wheels so directed that if the vehicle moved, its outermost forward point would describe a circle of 12,50 m radius, a vertical plane tangential to the side of the vehicle which faces outwards from the circle must be established by marking a line on the ground.

When the vehicle moves forward on either side following the circle of 12,50 m radius, no part of it may move outside the vertical plane by more than 0,80 m (see figure B).

For vehicles with an axle-lift device this requirement also applies with the axle(s) in the lifted position (within the meaning of 2.14). For vehicles of Category N with retractable axles in the lifted position, or loadable axles in the unladen condition, the figure of 0,80 m is replaced by 1,00 m.

7.6.3.

 Additional requirements for vehicles of categories M2 or M3

With the vehicle stationary, a vertical plane tangential to the side of the vehicle and facing outwards from the circle shall be established by marking a line on the ground. In the case of an articulated vehicle, the two rigid portions shall be aligned with the plane. When the vehicle moves from a straight line approach into the circular area described in section 7.6.1, no part of it shall move outside of that vertical plane by more than 0,60 m (see figures C and D).

Figure A

R = 12,5 m

r = 5,3 m

U = maximum 0,6

Figure D

U = maximum 0,6
7.6.4.

The requirements of sections 7.6.1 to 7.6.3 may also be verified, at the request of the manufacturer, with an appropriate equivalent calculation or geometric demonstration.

If, at the request of the manufacturer, vehicles of category N without steered rear axles are verified according to their geometric characteristics: a vehicle is deemed to comply with the requirements of paragraph 7.6.2 above if its rear overhang is not more than 60 % of the vehicle wheelbase.

7.6.5.

In the case of incomplete vehicles, the manufacturer must declare the maximum permissible dimensions for which the vehicle is to be checked against the requirements of sections 7.6.1 to 7.6.3.

7.7.   Additional requirements for motor vehicles of categories M2 and M3

The technically permissible maximum towable mass must not exceed 3 500 kg.

7.8.   Technically permissible maximum mass on the coupling point of motor vehicles and mounting instructions for couplings

7.8.1.

The technically permissible maximum mass on the coupling point of a motor vehicle designed to tow a centre-axle trailer and with a technically permissible maximum towable mass exceeding 3,5 tonnes must be at least equal to 10 % of its technically permissible maximum towable mass, or 1 000 kg, whichever is the lesser.

7.8.2.

The technically permissible maximum mass on the coupling point of a motor vehicle designed to tow a centre-axle trailer and with a technically permissible maximum towable mass not exceeding 3,5 tonnes must be at least equal to 4 % of its technically permissible maximum towable mass, or 25 kg, whichever is the greater.

7.8.3.

In the case of a motor vehicle with a technically permissible maximum laden mass not exceeding 3,5 tonnes, the manufacturer must specify in the owner's manual the conditions for the attachment of the coupling device to the motor vehicle.

Where the case occurs the above conditions must include the technically permissible maximum mass on the coupling point of the motor vehicle, the maximum permissible mass of the coupling device, the mounting points of the coupling device on the motor vehicle and the maximum permissible overhang of the coupling device.

7.9.   Hill-starting ability

Motor vehicles towing a trailer and laden to their technically permissible maximum laden mass of the combination, must be capable of starting five times within five minutes at an up-hill gradient of at least 12 %.

7.10.   Engine power/maximum mass ratio

Motor vehicles must provide an engine power output of at least 5 kW/t of the technically permissible maximum laden mass of the combination. In the case of a road tractor, the engine power must be at least 2,2 kW/t. The engine power is measured according to the provisions of Council Directive 80/1269/EEC ( 11 ).

7.11.   Conditions relating to the equivalence between certain non-air suspension and air suspension systems for vehicle driving axle(s)

7.11.1.

At the request of the manufacturer, the technical service must verify the equivalence of a non-air suspension to an air suspension for driving axle(s).

In order to be recognized as equivalent to air suspension, a non-air suspension must comply with the following requirements:

7.11.1.1.

During free transient low-frequency vertical oscillation of the sprung mass above a driving axle or group of axles, the measured frequency and damping with the suspension carrying its maximum load must fall within the limits defined in 7.11.1.2 to 7.11.1.5.

7.11.1.2.

Each axle must be fitted with hydraulic dampers. On groups of axles, the dampers must be positioned to minimize the oscillation of the groups of axles.

7.11.1.3.

The mean damping ratio Dm must be more than 20 % of critical damping for the suspension in its normal condition with hydraulic dampers in place and operating.

7.11.1.4.

The damping ratio Dr of the suspension with all hydraulic dampers removed or incapacitated must be not more than 50 % of Dm.

7.11.1.5.

The frequency of the sprung mass above the driving axle or group of axles in a free transient vertical oscillation must not be higher than 2,0 Hz.

7.11.1.6.

The frequency and damping of the suspension are defined in 7.11.2. The test procedures for measuring the frequency and damping are laid down in 7.11.3.

7.11.2.

 Definition of frequency and damping

In this definition a sprung mass M (kg) above a driving axle or group of axles is considered. The axle or group of axles has a total vertical stiffness between the road surface and the sprung mass of K newton/metre (N/m) and a total damping coefficient of C newton second per metre (N.s/m). The vertical displacement of the sprung mass is Z. The equation of motion for free oscillation of the sprung mass is: M d2Zdt2 + C dZdt + KZ = O

The frequency of oscillation of the sprung mass F (Hz) is: F = 12π2KM − C24M2

The damping is critical when C = Co,

where Co = 22KM

The damping ratio as a fraction of critical is C/Co.

During free transient oscillation of the sprung mass the vertical motion of the mass will follow a damped sinusoidal path (figure 2). The frequency can be estimated by measuring the time for as many cycles of oscillation as can be observed. The damping can be estimated by measuring the heights of successive peaks of the oscillation in the same direction. If the peak amplitudes of the first and second cycles of the oscillation are A1 and A2, then the damping ratio D is D = CCo = 12π ln A1A2

‘ln’ being the natural logarithm of the amplitude ratio.

7.11.3.

 Test procedure

To establish by test the damping ratio Dm, the damping ratio Dr with hydraulic dampers removed, and the frequency F of the suspension, the loaded vehicle is either:

(a) driven at low speed (5 km/h ± 1 km/h) over an 80 mm step with the profile shown in figure 1. The transient oscillation to be analysed for frequency and damping occurs after the wheels of the driving axle have left the step; or

(b) pulled down by its chassis so that the driving axle load is 1,5 times its maximum static value. The vehicle held down is suddenly released and the subsequent oscillation analysed; or

(c) pulled up by its chassis so that the sprung mass is lifted by 80 mm above the driving axle. The vehicle held up is suddenly dropped and the subsequent oscillation analysed; or

(d) subjected to other procedures insofar as it has been proved by the manufacturer, to the satisfaction of the technical service, that they are equivalent.

The vehicle must be fitted with a vertical displacement transducer between driving axle and chassis, directly above the driving axle. From the trace, the time interval between thefirst and second compression peaks can be measured to obtain the damping. For twin driving groups of axles, vertical displacement transducers must be fitted between each driving axle and the chassis directly above it.

The tyres must be inflated to the appropriate pressure recommended by the manufacturer for the test mass of the vehicle.

The test for verifying the equivalence of the suspensions is made at the technically permissible maximum mass on the axle or group of axles, and the equivalence assumed to cover all the lower masses.

ANNEX IV

This Annex contains the uniform procedure referred to in Article 4 of this Directive for the determination of the ‘registration/in-service maximum permissible masses’ in each Member State and the uniform technical requirements for loadable and retractable axles referred to in Article 5 of this Directive:

1.   Definitions

The following concepts are applicable in the framework of Article 4 of this Directive, until it is amended to incorporate harmonized maximum authorized masses. For the purpose of this Annex:

1.0.

‘Indivisible load’ means a load that cannot, for the purposes of carriage by road, be divided into two or more loads without undue expense or risk of damage and which, owing to its mass or dimension, cannot be carried by a vehicle the masses and dimensions of which comply with the maximum authorized masses and dimensions in force in a Member State.

1.1.

‘Registration/in-service maximum permissible laden mass’ means the maximum mass of the laden vehicle at which the vehicle itself can be registered or put into service in a Member State at the request of the vehicle manufacturer.

1.1.1.

For any technical configuration of the vehicle type, as defined by one set of the possible values of the items laid down in the information document in Annex II to this Directive, a set of intended registration/in-service maximum permissible laden masses may be given by the vehicle manufacturer at the time of the approval under this Directive so that they can be verified beforehand according to the requirements of section 2 of this Annex by the approval authority.

1.1.2.

Each of the Member States' authorities must, for their respective country, determine the registration/in-service maximum permissible laden mass of a given vehicle according to the following principles:

— by definition, only one registration/in-service maximum permissible laden mass may be attributed to one given technical configuration of the vehicle type as defined by one set of the possible values of the items laid down in the information document in Annex II to this Directive,

— the registration/in-service maximum permissible laden mass is determined as the greatest mass inferior or equal to the technically permissible maximum laden mass and to the relevant vehicle maximum authorized mass in force in that Member State (or a lower mass at the request of the manufacturer in agreement with the Member State's authorities), and which complies with the requirements laid down in section 2 of this Annex.

This does not preclude the possibility for Member States to allow a higher mass either for the purpose of carriage of indivisible loads or for the purposes of certain national transport operations that do not significantly affect international competition in the transport sector, within the limits of the technically permissible maximum laden mass of the vehicle.

1.1.3.

For the application of the separate directives listed in Annex IV to Directive 70/156/EEC, Member States may require that the vehicle complies with the provisions of those directives applicable to the category which corresponds, according to Annex II to Directive 70/156/EEC, to the actual value of the registration/in-service maximum permissible laden mass of the vehicle, and, for centre-axle trailers and semi-trailers, to the actual value of the mass corresponding to the load on the axles when the vehicle is loaded to its registration/in-service maximum permissible laden mass.

1.1.4.

Member States may require the registration/in-service maximum permissible laden mass not to depend on the tyres fitted.

1.2.

‘Registration/in-service maximum permissible mass on the axle in a Member State’ means the maximum laden mass on the axle stated by that Member State's authorities and at which the vehicle itself is to be registered or put into service in that Member State at the request of the vehicle manufacturer.

1.2.1.

For any technical configuration of the vehicle type, as defined by one set of the possible values of the items laid down in the information document of Annex II to this Directive, a set of intended registration/in-service maximum permissible masses on the axles may be given by the vehicle manufacturer at the time of the approval under this Directive so that they can be verified beforehand according to the requirements of section 2 of this Annex by the approval authority.

1.2.2.

Each of the Member States' authorities must, for their respective country, determine the registration/in-service maximum permissible mass on the axle according to the following principles:

— by definition, only one registration/in-service maximum permissible mass may be attributed to each axle for one given technical configuration of the vehicle type as defined by one set of the possible values of the items laid down in the information document of Annex II to this Directive,

— the registration/in-service maximum permissible mass on the axle is determined as the greatest mass inferior or equal to the technically permissible maximum mass on the axle and to the relevant maximum authorized mass on the axle in force in that Member State (or a lower mass at the request of the manufacturer in agreement with the Member State's authorities) and which complies with the requirements laid down in section 2 of this Annex.

This does not preclude the possibility for Member States to allow a higher mass either for the purpose of carriage of indivisible loads or for the purposes of certain national transport operations that do not significantly affect international competition in the transport sector, within the limits of the technically permissible maximum mass on the axle.

1.2.3.

Member States may require the registration/in-service maximum permissible mass on the axle not to depend on the tyres fitted.

1.3.

‘Registration/in-service maximum permissible mass on the group of axles in a Member State’ means the maximum laden mass on the group of axles stated by that Member State's authorities and at which the vehicle itself is to be registered or put into service in that Member State at the request of the vehicle manufacturer.

1.3.1.

For any technical configuration of the vehicle type, as defined by one set of the possible values of the items laid down in the information document of Annex II to this Directive, a set of intended registration/in-service maximum permissible masses on the group of axles may be given by the vehicle manufacturer at the time of the approval under this Directive so that they can be verified beforehand by the approval authority according to the requirements of section 2 of this Annex.

1.3.2.

Each of the Member States' authorities must, for their respective country, determine the registration/in-service maximum permissible mass on the group of axles according to the following principles:

— by definition, only one registration/in-service maximum permissible mass may be attributed to each group of axles for one given technical configuration of the vehicle type as defined by one set of the possible values of the items laid down in the information document of Annex II to this Directive,

— the registration/in-service maximum permissible mass on the group of axles is determined as the greatest mass inferior or equal to the technically permissible maximum mass on the group of axles and to the relevant maximum authorized mass on the group of axles in force in that Member State (or a lower mass at the request of the manufacturer in agreement with the Member State's authorities) and which complies with the requirements laid down in section 2 of this Annex.

This does not preclude the possibility for Member States to allow a higher mass for either the purpose of carriage of indivisible loads or for the purposes of certain national transport operations that do not significantly affect international competition in the transport sector, within the limits of the technically permissible maximum mass on the group of axles.

1.4.

‘Registration/in-service maximum permissible towable mass in a Member State’ of a motor vehicle means the maximum mass to be towed by the motor vehicle, given by that Member State's authorities, and at which the motor vehicle is to be registered or put into service in the Member State at the request of the vehicle manufacturer.

1.4.1.

For any technical configuration of the vehicle type, as defined by one set of the possible values of the items laid down in the information document of Annex II to this Directive, a set of intended registration/in-service maximum permissible towable masses may be given by the vehicle manufacturer at the time of the approval under this Directive so that they can be verified beforehand by the approval authority according to the requirements of section 2 of this Annex.

1.4.2.

Each of the Member States' authorities must, for their respective country, determine the registration/in-service maximum permissible towable mass of a given vehicle according to the following principles:

— by definition, only one registration/in-service maximum permissible towable mass may be attributed to one given technical configuration of the vehicle type as defined by one set of the possible values of the items laid down in the information document of Annex II to this Directive,

— the registration/in-service maximum permissible towable mass is determined as the greatest mass inferior or equal to the technically permissible maximum towable mass and to the relevant maximum authorized masses in force in that Member State (or a lower mass at the request of the manufacturer in agreement with the Member State's authorities) and which complies with the requirements laid down in section 2 of this Annex.

This does not preclude the possibility for Member States to allow a higher mass for either the purpose of carriage of indivisible loads or for the purposes of certain national transport operations that do not significantly affect international competition in the transport sector, within the limits of the technically permissible maximum towable mass of the vehicle.

1.5.

‘Registration/in-service maximum permissible laden mass of the combination in a Member State’ means the sum of the masses of the laden vehicle and of its laden trailer at which the motor vehicle is to be registered or put into service in that Member State at the request of the vehicle manufacturer.

1.5.1.

For any technical configuration of the vehicle type, as defined by one set of the possible values of the items laid down in the information document of Annex II to this Directive, a set of intended registration/in-service maximum permissible laden masses of the combination may be given by the vehicle manufacturer at the time of the approval under this Directive so that they can be verified beforehand by the approval authority according to the requirements of section 2 of this Annex.

1.5.2.

Each of the Member States' authorities must, for their respective country, determine the registration/in-service maximum permissible laden mass of the combination of a given vehicle according to the following principles:

— by definition, and in principle, only one registration/in-service maximum permissible laden mass of the combination may be attributed to one given technical configuration of the motor vehicle type as defined by one set of the possible values of the items laid down in the information document of Annex II to this Directive. However, according to the practice in force in the Member State, there may be distinguished one registration/in-service maximum permissible laden mass of the combination per total intended number of axles of the combination and this mass may also depend on other characteristics of the intended combination, such as the intended kind of transport (e.g. ISO 40-foot containers in combined transport, etc.),

— the registration/in-service maximum permissible laden mass of the combination is determined as the greatest mass inferior or equal to the technically permissible maximum laden mass of the combination and to the relevant maximum authorized masses in force in that Member State (or a lower mass at the request of the manufacturer in agreement with the Member State's authorities) and which complies with the requirements laid down in section 2 of this Annex.

This does not preclude the possibility for Member States to allow a higher mass either for the purpose of carriage of indivisible loads or for the purposes of certain national transport operations which do not significantly affect international competition in the transport sector, within the limits of the technically permissible maximum laden mass of the combination.

2.   Determination of the registration/in-service maximum permissible masses

2.1.

The provisions of section 7.4 of Annex I to this Directive apply for the determination by the Member States' authorities of the different registration/in-service maximum permissible masses. For this purpose, the notations M, mi, µj, TM and MC of that paragraph respectively designate the registration/in-service maximum permissible laden mass of the vehicle, the registration/in-service maximum permissible mass on the axle designated ‘i’, on the solo axle or group of axles designated ‘j’, the registration/in-service maximum permissible towable mass, and the registration/in-service maximum permissible laden mass of the combination.

2.2.

Determination of the registration/in-service maximum permissible towable mass of a motor vehicle:

2.2.1.

The registration/in-service maximum permissible towable mass of a motor vehicle intended to tow a trailer, whether it is a towing vehicle or not, is the lowest of the following values:

(a) the technically permissible maximum towable mass based on the construction and performance of the vehicle and/or the strength of the mechanical coupling device;

(b) vehicles only intended to tow trailers without service brakes: half of the mass of the vehicle in running order with a maximum of 0,750 t;

(c) vehicles with a maximum mass not exceeding 3,5 t only intended to tow trailers with inertia (overrun) braking systems: the registration/in-service maximum permissible laden mass of the vehicle, or, for off-road vehicles (see section 7.5 of Annex I), 1,5 times that mass with a maximum of 3,5 t;

(d) vehicles with a maximum mass exceeding 3,5 t only intended to tow trailers with inertia (overrun) service brakes: 3,5 t;

(e) 

vehicles intended to tow trailers, apart from semi-trailers, with continuous braking systems: 1,5 times the registration/in-service maximum permissible laden mass of the vehicle.

By way of derogation from the provisions of section 1.4 of this Annex, for vehicles intended to tow more than one of the kinds of trailers referred to in subparagraphs (b), (c), (d) and (e) above, up to three different registration/in-service maximum permissible towable masses may be defined for each technical configuration of the vehicle type, according to the characteristics of the brake connectors of the motor vehicle: one for trailers without service brakes, one for trailers with inertia brakes, and one for trailers with a continuous braking system. These masses are determined as mentioned above, by respectively applying subpagraphs (b), (c), (d) and (e).

A mass lower than the one so determined may be accepted by the Member State at the request of the manufacturer.

3.   Technical requirements for the installation of retractable or loadable axles on vehicles (Annex I, sections 2.14 to 2.16)

3.1.

Any vehicle may be permitted with one or more retractable or loadable axles.

3.2.

If a vehicle is fitted with one or more retractable or loadable axles (Annex I, sections 2.14 to 2.16) it must be ensured that under all driving conditions with the exception of those mentioned in point 3.5 below the registration/in-service maximum permissible masses on the axles and groups of axles are not exceeded.  To that end the retractable or loadable axle must lower to the ground or be loaded automatically if the nearest axle(s) of the group or the front axle of the motor vehicle is (are) laden to its (their) registration/in-service maximum permissible mass(es).

3.4.

Every axle-lift device fitted to a vehicle to which this Directive applies, as well as the systems for its operation, must be designed and installed in such a manner as to protect them against any improper use or tampering.

3.5.

Requirements for the starting (moving off) of motor vehicles on slippery surfaces.

3.5.1.

By way of derogation from provisions of 3.2, and to help motor vehicles or vehicle combinations move off on slippery ground, and to increase the traction of the tyres on these surfaces, the axle lift may also actuate the retractable or loadable axle of a motor vehicle or semi-trailer to increase the mass on the driving axle of the motor vehicle, subject to the following conditions:

— the mass corresponding to the load on each axle of the vehicle may exceed the relevant maximum authorized mass on the axle in force in the Member State by up to 30 % provided it does not exceed the value stated by the manufacturer for this special purpose,

— the mass corresponding to the remaining load on the front axle must remain above zero (i.e. in case of a rear loadable axle with long rear overhang, the vehicle must not tip up),

— the retractable or loadable axle must be actuated only by a special control device,

— after the motor vehicle has moved off and before it exceeds a speed of 30 km/h, the axle must automatically lower again to the ground or be reloaded.
