Proposal from the VRU-Proxi informal group to amend the detection area in the proposal for Supplement 3 to the UN Regulation on blind-spot information systems.

Supplement 1 to the original version of UN R151 (GRSG/2019/25) amended the paragraph 5.3.1.4. to add an explicit requirement for the maximum detection distance. The Supplement did not intend to delete or suggest a change in the requirements for the information signal boundaries or the detection area around the front wheel. This proposal reintroduces and clarifies the requirement for the detection area around the front wheel.
