| Summary | Proposal to clarify provisions regarding the actuation of the parking brake warning device to cover the case of electric control transmission systems where there may be a transition between parked (applied) and un-parked (released) braking states. The aim is to reduce risks of user confusion by specifying that the warning device would be actuated only after the parking brake has achieved a stable applied state. | ||||||||

84. The expert from OICA presented GRVA-12-48, proposing to allow that the required warning actuation may be delayed until the parking brake was in a stable state. The proposal received comments from France, Germany, United Kingdom of Great Britain and Northern Ireland and Russian Federation. GRVA agreed that the expert from OICA, in consultation with interested Contracting Parties, would submit a revised proposal on the basis of ECE/TRANS/WP.29/GRVA/2022/11, at its May 2022 session. |
