This legislation, known as the AV Safety Data Act, aims to enhance incident reporting for vehicles equipped with Automated Driving Systems (ADS) or Level 2 Advanced Driver Assistance Systems (ADAS). It defines "covered entities" as manufacturers and operators subject to NHTSA's Third Amended Standing General Order 2021-01, and "covered vehicles" as those with ADS or Level 2 ADAS. A key new definition is an "unplanned stoppage event," describing a non-collision incident where a vehicle stops on a public road, interferes with traffic, emergency services, or a work zone, and cannot proceed without intervention. The bill requires covered entities to submit monthly reports to the National Highway Traffic Safety Administration (NHTSA) within 90 days of enactment. These reports must include detailed information such as miles traveled, data on collisions resulting in injury to vulnerable road users or occupants of other vehicles, and comprehensive details about unplanned stoppage events. For Level 2 ADAS, data submission is limited to when the system was engaged or immediately preceding an unplanned stoppage, and must exclude personally identifiable information. All submitted information and reports will be made publicly available by NHTSA in a machine-readable format within 120 days of enactment.
