Proposal to amend para. 5.6.1.2.7. to increase the maximum RCP operating range from 6 m to 15 m. UN R79 currently limits the maximum RCP operating range to 6 m, resulting in effective usable range of 2 or 3 m due to radio wave-based ranging inaccuracy. A 15-meter range would enhance RCP function usefulness and safety, reducing driver movement and blind areas. RCP systems with extended ranges have been used in large markets without identified safety threats. The amendment is proposed as a supplement to the 03 and 04 series of amendments to UN R79.
