The Commission's amended proposal does not incorporate the European Parliament's amendments seeking to obtain additional derogations in that it considers that granting derogations beyond 2006 would compromise the objective of harmonization and put manufacturers who had adjusted their production lines in order to comply with the directive at a disadvantage. However, it does incorporate the European Parliament's amendment seeking to introduce a number of additional elements in the directive with regard to licensing and using vehicles (pneumatic suspension to prevent excessive road damage, maximum axle loads and vehicles to be capable of turning through 360 degrees).�
