19. The expert from OICA proposed to remove the current restriction in paragraph 6.12.1. that prohibits the fitment of parking lamps to vehicles which exceed 2 m in width (GRE-90-22). Several experts supported the proposal and further pointed out the need to also remove the length restriction of 6 m in the same paragraph. GRE realized that these two restrictions had originated in the 1968 Vienna Convention on Road Traffic, and invited OICA to update their proposal for consideration at the next session.
