HR 6688 requires the National Highway Traffic Safety Administration (NHTSA) to develop guidelines on how driver-assistance features such as automatic emergency braking, lane-keeping assist, and blind-spot warnings must perform after a vehicle is modified or repaired. A study must be completed within one year to inform those guidelines, which must be published within two years. Starting with 2028 model year vehicles, automakers must share technical information with owners and NHTSA about how their systems respond to modifications.
The bill directly affects car owners who modify or repair their vehicles, independent repair shops, and car manufacturers. Everyday drivers who rely on modern safety features are also affected by whether those systems function correctly after service or alteration.
Currently no standard rules require these safety systems to be checked or recalibrated after changes such as a suspension lift, tire swap, or collision repair. The guidelines would establish how much a change in vehicle height, wheel size, or sensor position can occur before safety features may stop working correctly, and what steps mechanics must follow afterward.
Car manufacturers who do not meet the guidelines could face financial penalties under existing federal law.
