UN Regulations Nos. 49 and 83 include provisions for a “driver inducement system” that alerts drivers of low reagent levels (urea, etc.) critical to correct emissions control performance and eventually prevents vehicle operation if the reagent tank is empty. Under UN R49 (para. 5.2), rescue, police, and other emergency/special use vehicles are exempted from this requirement. This proposal would extend the same treatment under UN R83.

14. The expert from Italy presented GRPE-72-03 on amendments to Regulation No. 83 to introduce the possibility to inhibit the driver inducement system of rescue and police service vehicles.

15. The expert from OICA supported the proposal and its alignment with Regulation No. 49. The expert from the Netherlands agreed in principle with the proposal but expressed a reservation to further examine the possible drawbacks such as the exemption proposed for specific vehicles when becoming publicly available. The expert from T&E supported this reservation and underlined the need to reinsert the initial system when these vehicles abandon the rescue and police services in the second hand market.

16. The Chair invited the expert from Italy to submit an updated proposal as an official document at the next GRPE session taking into account the comments received.
