ADAS Functionality and Integrity Act

HR 6688, the ADAS Functionality and Integrity Act, requires the National Highway Traffic Safety Administration (NHTSA) to develop guidelines within 24 months to ensure Advanced Driver Assistance Systems (ADAS) in passenger vehicles (model year 2028+) maintain safety after modifications like tire changes or suspension adjustments. The guidelines will specify allowable modification ranges (e.g., ride height, sensor alignment), calibration procedures, and verification tests for repair shops and owners. This directly affects vehicle manufacturers, independent repair facilities, and car owners who customize or modify vehicles. The bill mandates that guidelines be based on empirical data and reference existing safety assessment methods, with penalties for non-compliance.
