The National Highway Traffic Safety Administration (NHTSA) has denied petitions requesting changes to the rules for adaptive driving beam (ADB) headlighting systems in vehicles. These petitions followed a final rule issued on February 22, 2022, that updated the Federal Motor Vehicle Safety Standard to allow for the certification of ADB headlamps in the U.S. Despite industry concerns about technical complexities, testing standards, and the desire for more flexibility in the rules, NHTSA maintained its position that the existing standards balance safety with performance. The agency emphasized that ADB systems must meet both vehicle-level and component-level requirements to ensure they improve visibility without causing excessive glare to other drivers.
Simple Explanation
The government decided not to change some new car light rules because they think the lights, called ADB headlamps, are safe as they are. They believe these lights help drivers see better without being too bright for others on the road.
