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)

OF 

CERTAIN CATEGORIES OF MOTOR VEHICLES 

THE COUNCIL OF THE EUROPEAN  COMMUNITIES 

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

7.1. 

General 

7.1.1. 

The  speed  limitation must  be  such  that  the  vehicle  in normal  use, 
despite  the  vibrations  to which  it may  be  subjected,  complies  with 
the  provisions  of  this  Directive.  The  speed  limitation  device  shall 
be  so  designed,  constructed  and  assembled  as  to enable  the  vehicle 
in normal  use,  fitted  with  the  speed  limitation  device,  to  comply 
with  the  provisions  of  this  Directive. 

7.1.2. 

In particular,  the  speed  limitation  device  of  the  vehicle  must  be  so 
designed,  constructed  and  assembled  as  to  resist  corrosion  and  aging 
phenomena  to which  it may  be  exposed  and  to  resist  tampering. 

7.1.2.1. 

The  limitation  threshold  must  not,  in any  case,  be  capable  of  being 
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  and  the  speed  limitation  device  shall 
not  actuate  the  vehicle's  service  braking  system.  A  permanent  brake 
(e.g.  retarder) may  be  incorporated  only  if  it operates  after  the 
speed  limitation  function  or  the  speed  limitation  device  has 
restricted  the  fuel  feed  to  the minimum  fuel  position. 

The  speed  limitation  function  or  the  speed  limitation  device  must  be 
such  that  it  does  not  affect  the  vehicle's  road  speed  if  a  positive 
action  on  the  accelerator  is applied  when  the  vehicle  Is  running  at 
its set  speed. 

7.1.5. 

The  speed  limitation  function  or  the  speed  limitation  device  may 
allow  normal  accelerator  control  for  the  purposes  of  gear  changing. 

7.1.6. 

7.1.7. 

No malfunction  shall  result  in an  increase  In engine  power  above  that 
demanded  by  the  position of  the  driver's  accelerator. 

The  speed  limitation  function  shall  be obtained  regardless  of  the 
accelerator  control  used  if  there  is more  than  one  such  control  which 
may  be  reached  from  the  driver's  seating  position.
