View Rule

Pursuant to a statutory mandate in the Bipartisan Infrastructure Law, this notice will seek comment on a proposal to require and/or standardize performance for Light Vehicle Automatic Emergency Braking (AEB), including Pedestrian AEB (PAEB), on all newly manufactured light vehicles. A vehicle with AEB detects crash imminent situations in which the vehicle is moving forward towards another vehicle and/or a pedestrian, and automatically applies the brakes to prevent the crash from occurring, or to mitigate the severity of the crash. This rulemaking would set performance requirements and would specify a test procedure under which compliance with those requirements would be measured.
