Proposal for a 
COUNCIL DIRFPTfYp 
RELATING TO SPEED LIMITATION DEVICES 
OF 
CERTAIN CATEGORIES OF MOTOR VEHiaES 
(presented by the Commission)

EXPLANATORY MEMORANDUM 
I. BACKGROUND 
1. The Implementation of the EEC type approval procedure for motor vehicles 
and their trailers covered by Council directive 70/156/EEC of 6 February 
19701) comprises especially the adoption of the last separate 
directives for passenger cars (tyres, masses and dimensions, safety 
glazing). The Commission has submitted proposals for this reason in 
January 1990. Furthermore the framework directive assigns the adoption 
of special provisions for goods vehicles, that is to say trucks with a 
maximum mass exceeding 3,5 t. To take care of the precise and 
comprehensive content of these provisions It is deemed opportune to 
adopt in particular harmonized Community requirements. Inter alia, 
masses and dimensions (Itarns 2.2, 2.4, 2,6 and 2,8 of Annex II), speed 
limiters and external projections of cabs (item 12.4 of Annex 11) as 
special safety provisions for goods vehicles. 
2. The European Parliament has adopted, on the 13 March 1984, a resolution 
on the introduction of a programme of Community measures to promote road 
safety2* and on the 18 February 1986 another resolution on common 
measures to reduce road accidents as part of the Community's programme 
for Road Safety Year 19863). The Council and the Commission are asked 
by these resolutions to take the necessary measures with the aim of 
promoting road safety.

3. In view of the entry into force of the Single European Act and of the 
aim of a single internal market to be achieved by the end of 1992, It is 
now urgent that the remaining measures that are needed In order to 
complete EEC type approval should be adopted. 
4. The legal/administrative procedure put forward in the enacting terms of 
these proposals does riot depart from that laid down In framework 
directive 70/1SA/ESC that is currently In force except ae regards the 
procedure for adaptation to technical progress, whereby tHe Hernialory 
Committed has fceen replaced by the Advisory Committee. Indeed, the 
Commission Intends to apply the provisions of the Single Act, which 
provide for the delegation of power to the Commission in order to 
proceed with this task. 
5. With regard to the other options, such as that of the method of 
harmonization (total or optional), the Commission is still applying the 
solutions currently in force. 
However, the Commission does not intend to neglect this Important 
matter; considering that the total harmonization will be essential In 
order to fully achieve the large single market, it intends to put 
forward relevant proposals when the framework directive 70/156/EEC is 
next amended. 
11. REASONS FOR AND CONTENT OF THE PROPOSALS 
6. Speed llmiters for heavy trucks and coaches 
The Commission was asked by the resolutions 1984 and 1986 of the European 
Parliament to submit, inter alia, appropriate provisions for the 
obligatory fitting of speed llmiters in heavy goods vehicles. The 
mandatory equipment of road vehicles with these devices is considered to 
improve road safety, to reduce the severity of injuries in the case of 
accidents and to achieve a reduction of air pollution and fuel 
consumption. 
This draft proposal for a Council directive is mainly based on the 
corresponding draft ECE Regulation (Economic Commission for Europe of the 
United Nations) which had been recently approved by the Contracting 
Parties of the 1958 Agreement relating to uniform criteria for 
homologations of vehicle parts and their mutual recognition by the 
contracting parties. The speed limits at which the speed llmiters have to 
be set for certain categories of motor vehicles correspond to those values 
laid down in a proposal for a Council directive relating to speed 
limitations for certain categories of motor vehicles in the Community4)

Having regard to the Treaty establishing the European Economic Community, and In 
particular Article 100a thereof, 
Having regard to the proposal from the Commies ion,1 
in cooperation with the European Parliament,2 
Having regard to the opinion of the Economic and Social Committee.3 
Whereas it is important to adopt measures with the aim of progressively 
establishing the internal market over a period expiring on 31 December 1992; 
whereas the internal market shall comprise an area without internal frontiers in 
which the free movement of goods, persons, services and capital Is ensured; 
Whereas the technical requirements which motor vehicles must satisfy pursuant to 
national taws relate, inter alia, to speed limitation of certain categories of 
vehicles; 
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 EEC type-approval procedure which was the subject of Council

increased or removed temporarily or permanently on vehicles in use. 
The inviolability shall be demonstrated to the technical service with 
documentation analysing the failure mode in which the system will be 
global y examined. 
The analysis shall show, taking into account the different states 
taken by the system, the consequences of a modification of the input 
or output states on the functioning, the possibilities to obtain 
these modifications by failures or by voluntary violation and the 
possibility of their occurrence. The analysis level will be always 
to the first failure. 
7.1.2.2. The speed limitation function, the speed limitation device and the 
connections necessary for its operation, except those essential for 
the running of the vehicle, shall be capable of being protected from
