17. The expert from Germany proposed to allow (a) the manual switch-off of all lighting devices in vehicles used by special forces and (b) the activation of hazard warning lights when opening a door in vehicles not equipped with a door assistance and warning system (ECE/TRANS/WP.29/GRE/2019/8). The experts from France, Japan and United Kingdom of Great Britain and Northern Ireland were not in a position to support the derogation (a) and indicated that such exceptions should be done in the national or regional legislation, rather than in a UN Regulation. For proposal (b), the expert from EC pointed out that it constitutes a new requirement and, thus, should be introduced by a new series of amendments. The experts from Czechia, Netherlands, United Kingdom of Great Britain and Northern Ireland and OICA were of the view that proposal (b) goes beyond the scope of GRE and should be addressed by the Working Party on General Safety Provisions (GRSG). The Chair requested the secretariat to bring the issue to the attention of GRSG.

26. The expert from Germany tabled a proposal that allows the manual switch-off of all lighting devices in vehicles used by authorities responsible for maintaining public order (ECE/TRANS/WP.29/GRE/2019/14 and GRE-82-41-Rev.1). Some experts were of the view that such a derogation should be addressed in the framework of national or regional rather than international law. Several experts indicated practical difficulties in identifying those vehicles when at the stage of type approval and manufacturing. GRE agreed to revert to the issue at the next session.

75. The expert from Germany introduced ECE/TRANS/WP.29/GRE/2019/8 proposing the activation of hazard warning lights when opening a door in vehicles not equipped with a door assistance and warning system, which had been forwarded to GRSG for consideration.

76. GRSG agreed that the proposed solution was not favoured by the group as it was not clear whom to warn, persons inside the vehicle or those outside, whether the warning would come too late anyhow or whether other solutions such as sensors would be more effective.
