COMMISSION OF THE EUROPEAN COMMUNITIES
                                         Brussels, 04.11.1996

               OPINION OF THE COMMISSION
      pursuant to Article 189 b (2) (d) of the EC Treaty,
            on the European Parliament's amendments
        to the Council's common position regarding the
                          proposal for a
 EUROPEAN PARLIAMENT AND COUNCIL DIRECTIVE
Relating to The Front-Impact Resistance of Motor Vehicles and
                 Amending Directive 70/156/EEC
  AMENDING THE PROPOSAL OF THE COMMISSION
         pursuant to Article 189 a (2) of the EC Treaty
 ---pagebreak---  ---pagebreak--- 1.   BACKGROUND
1.1  Obj ective-TDf the proposal
    Thé reduction of the number of people killed or seriously injured in road
    accidents by the introduction of new standards for the frontal impact resistance of
    passenger cars. The new test procedure would be mandatory for new vehicle
    types approved after 1 October 1998 and would apply to all new vehicles
    registered after 1' October 2003.
1.2 Commission original proposal                                           13.12.94
1.3 Opinion of the Economic and Social Committee                          "05.07.95
1.4 Opinion of the European Parliament on first reading                 * 12.07.95
    The Parliament rejected the first stage of the two-stage approach proposed by the
    Commission in favour of a single phase based on the offset deformable barrier
    test. A series of amendments supplied technical details of the test which were not
    available to the Commission at the time of drafting the original proposal. The
    Commission accepted almost all the amendments.
1.5 Commission amended proposal (COM(95) 510)                              27.11.95
1.6 Adoption of the Common Position                                        28.05.96
    The Council accepted the amended proposal of the Commission and made a
    number of changes to both the articles and technical annexes, further improving
    the precision of the text. In particular an appendix was added to Annex II to
    provide a certification procedure for the ankle joint of the test dummy.
1.7 Commission response to the Common Position                             13.06.96

 ---pagebreak--- 2.  POSITION OF THE EUROPEAN PARLIAMENT - SECOND READING
2.1 The Parliament at its plenary session in September 1996 accepted the substance of
    the Common Position but added the 13 amendments recommended by the
    Committee on Economic and Monetary Affairs and Industrial Policy (EMAC).
    These amendments concerned the technical details of the new Appendix 7,
    updating in respect of further research by the European Experimental Vehicles
    Committee (EEVC).
2.2 The Rapporteur for EMAC indicated that the Commission might wish to place a
    reserve on some of the figures in the amendments tabled.
2.3 The Commission, in accepting the amendments in principle, stated that if further
    changes to the technical details should be required, these could be incorporated
    either by agreement between the Institutions or via the Committee for Adaptation
    to Technical Progress.
3.  COMMISSION POSITION
3.1 The Commission can accept all 13 amendments since they improve further the
    precision and practicability of the procedure for certification of the ankle of the
    test dummy.
3.2 The Commission also notes that the amendments are based on the ongoing
    research of the European Experimental Vehicles Committee. In the light of the
    final report of this Committee, the Commission will, in due time, amend certain
    technical details of Appendix 7 through the procedure of Adaptation to Technical
    Progress.
