Proposal to enable the optional use of hazard warning lamps on L1 category vehicles to alert other vehicles in case of breakdown or other situations that could lead to danger on the road. This proposal brings L1 category warning signal options in line with those for other 2-wheeled vehicles.

IMMA correction (of an oversight on
inclusion of the colors of the lights from R53 to ensure complete alignment of UN R74 with R53) to its proposal to enable the optional use of hazard warning lamps on L1 category vehicles to alert other vehicles in case of breakdown or other situations that could lead to danger on the road.

Proposal to enable the optional use of hazard warning lamps on L1 category vehicles to alert other vehicles in case of breakdown or other situations that could lead to danger on the road.

This proposal brings L1 category warning signal options in line with those for other 2-wheeled vehicles.

Pursuant to item 5(f) of GRE-69, the GTB proposal (GRE/2013/5) to cease issuing type approvals under UN R5 and R31 was approved.

This prompted proposals to look for similar references in UN R53, R74 and R86. No references to UN R31 were found, but references to similarly ‘frozen’ regulations (UN R1, R8, R20, R56, R57, R72, R76 and R82) were found.

The present document proposes to delete these obsolete references in UN R53 and R74.
