Collision Avoidance Systems Act of 2025

The "Collision Avoidance Systems Act of 2025" aims to enhance vehicle safety by clarifying regulations regarding high-mounted stop lamps . It specifies that Federal Motor Vehicle Safety Standard Number 108 is to be interpreted as allowing the use of pulsating light systems on vehicles covered by the standard. The bill mandates the Secretary of Transportation to issue new regulations within 180 days of enactment. These regulations will update Standard 108 to include performance-based standards for pulsating light systems and officially permit their use on motor vehicles. A pulsating light system is defined as one where the lamp pulses rapidly up to four times for no more than 1.2 seconds upon brake application, then converts to a continuous light, with a minimum 5-second lockout period before subsequent pulsing.
