Updated proposal to introduce the automatic activation of the hazard warning lights upon detection of excess temperatures in engine and/or heater compartment in buses and coaches.
This proposal supersedes document GRSG-104-04.
7. The expert from Germany presented ECE/TRANS/WP.29/GRSG/2014/3 proposing to introduce the automatic activation of the hazard warning lights upon detection of excess temperatures in the engine and/or the heater compartment. The expert from OICA stressed the need to insert transitional provisions and announced the preparation of a concrete proposal for consideration at the next session. GRSG adopted the proposal, as reproduced below, and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their March 2015 sessions, as draft Supplement 3 to the 05 series of amendments and as draft Supplement 2 to the 06 series of amendments to UN Regulation No. 107. GRSG underlined the need that WP.29 shall adopt these amendments together with an parallel amendments to UN Regulation No. 48 to be submitted by the Working Party on Lighting and Light-signalling (GRE). The expert from Germany volunteered to submit an official document for consideration by GRE at its October 2014 session.
Annex 3, paragraph 7.5.1.5., amend to read:
| “7.5.1.5. | In the case of vehicles having the engine located to the rear of the driver’s compartment, the compartment shall be equipped with an alarm system providing the driver with both an acoustic and a visual signal, and activating the hazard warning signal in the event of excess temperature in the engine compartment and in each compartment where a combustion heater is located.” |
Annex 3, paragraph 7.5.6.2., amend to read:
| “7.5.6.2. | Upon detection, the system given in paragraph 7.5.6.1. shall provide the driver with both an acoustic and a visual signal in the driver’s compartment and shall activate the hazard warning signal.” |
10. The expert from Germany suggested activating automatically the hazard warning lights in case of a detection of a temperature excess in the engine and/or heater compartment (GRSG-105-33). GRSG noted a number of concerns on the use of hazard warning lights specified in the 1968 Vienna Convention. GRSG agreed to resume consideration of the proposal at the next session on the basis of an official symbol.
11. Referring to GRSG-104-04, the expert from Germany suggested activating automatically the hazard warning lights in case of a detection of a temperature excess in the engine and/or heater compartment. GRSG noted a number of concerns. Following the discussion, the expert from Germany volunteered to prepare a revised proposal for consideration at the next GRSG session taking into account the comments received.
