Proposal to introduce a Front Zero-Speed Indicator (FZSI) system on motor vehicles to signal complete vehicle stops to vulnerable road users. The system activates exclusively when vehicle speed equals 0 km/h and deactivates when speed exceeds 0 km/h. A horizontal light strip of minimum 30 cm width positioned at the upper windshield edge or front roofline provides the signal. Primary color is red (wavelength 620–750 nm); secondary option is high-luminance turquoise or green if required by applicable legislation. Brightness adjusts automatically via ambient light sensors. The system integrates with existing vehicle CAN-bus networks and serves as direct communication for autonomous vehicles.

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.
