Proposal for a Front Zero-Speed Indicator Vehicle (FZSIV) (Installation of lighting and light-signalling devices)

Proposal to amend the definitions of stop lamps in UN R48, paragraph 2.7.12, and UN R7, paragraph 1.3, to indicate that stop lamps signal when a vehicle is stopped, when one or more wheels are blocked, and to transmit an equivalent signal on the front of the vehicle. The document presents a Front Stop Lamp system designed to activate only when the vehicle is at rest with zero speed or when wheels are locked, using a dynamic sensor to detect wheel rotation angles below 5.6 degrees as blocked and above 5.6 degrees as unblocked, remaining inactive during vehicle motion except to signal incidents involving wheel blockage, thereby providing clearer communication of vehicle status to other road users and pedestrians at intersections, roundabouts, and other traffic situations.
