Collision Avoidance Systems Act of 2023

This bill clarifies that existing vehicle safety standards (Standard 108) permit pulsating light systems on stop lamps, which rapidly pulse for up to 1.2 seconds when brakes are applied before switching to steady light. It requires the Transportation Secretary to update Standard 108 within 180 days to include specific performance standards for these systems. The bill directly affects vehicle manufacturers and the National Highway Traffic Safety Administration by formalizing the use of pulsating lights in safety regulations. It does not change current vehicle requirements but updates the regulatory framework to explicitly allow this technology. The key change is making pulsating stop lights a compliant option under federal safety standards.
