WHAT THE BILL DOES
AI-writtenThis bill matters because modern cars increasingly rely on advanced driver assistance systems (ADAS) like automatic emergency braking, lane keeping, and adaptive cruise control for safety. When vehicles are modified—whether for aesthetic reasons (like lift kits or larger wheels) or performance upgrades—or simply repaired after a collision, these systems can be affected. Without clear standards, there's a risk that these crucial safety features might not work as intended, potentially making vehicles less safe after modifications or repairs.
If this bill becomes law, it would help ensure that vehicle safety features remain fully functional, regardless of who services the car or if minor modifications are made. It provides clarity for repair shops on how to properly calibrate these systems and gives owners more confidence in the safety of their vehicles. If it doesn't become law, the automotive industry might continue with varying or unclear standards regarding ADAS functionality after modifications or repairs, potentially leading to inconsistencies in safety performance and making it harder for independent repair facilities to service these complex systems effectively.
KEY PROVISIONS
5AI-extractedPROVISION 01
NHTSA must develop and publish guidelines within 24 months for how advanced driver assistance systems (ADAS) should function in modified or repaired vehicles (model year 2028 and later).
This establishes a national standard to ensure critical safety features continue to work after car modifications or repairs.
PROVISION 02
The guidelines must include specific allowable modification ranges, calibration procedures, and testing protocols to verify ADAS integrity.
This provides clear technical details and methods for car owners, manufacturers, and repair shops to ensure safety system performance.
PROVISION 03
Manufacturers will be required to provide vehicle tolerance and system sensitivity information to owners and NHTSA within 30 days of a vehicle's release.
This increases transparency and access to crucial data for owners and independent repair facilities to properly maintain and repair ADAS.
PROVISION 04
NHTSA must conduct a study within 12 months to assess the safety needs, feasibility, and costs of developing these ADAS guidelines.
This ensures the guidelines are based on thorough research and practical considerations before full implementation.
PROVISION 05
Manufacturers who do not meet the established guidelines for ADAS functionality in modified vehicles will face civil penalties.
This provides a mechanism to enforce the guidelines and hold manufacturers accountable for compliance.
