The bill raises ADAS safety, transparency, and repairability through standardized tests, disclosures, and evidence-based rulemaking but does so at the cost of higher prices, implementation delays, potential legal disputes, and risks to independent repair competition.
Vehicle owners and drivers (homeowners, transportation workers, middle-class families) and repair providers can confirm ADAS function after repairs or modifications using standardized confirmatory tests and NCAP-based calibration scoring, improving safety and reducing crash risk.
Vehicle owners and independent aftermarket providers gain timely manufacturer disclosure of tolerance and sensitivity data (within 30 days of vehicle release), giving actionable information for safe customization and repair.
Independent repair shops and service providers get statutory definitions, guidance, and repeatable calibration procedures that support competition, reduce repair uncertainty, and lower liability risk for aftermarket calibrations.
Vehicle buyers (homeowners) and small aftermarket businesses will likely face higher costs because manufacturers must comply with new requirements and repair shops may need new equipment, training, and time for confirmatory tests, which can increase vehicle and repair prices.
Vehicle owners and drivers may see delays in immediate protections or in making aftermarket modifications because mandated studies, compliance timelines, and the time needed to publish standards could slow implementation.
Independent repair shops and small businesses risk reduced access to proprietary calibration methods, tools, or data and may face shifted liabilities if guidelines or broad statutory definitions favor manufacturers, undermining competition and creating legal risk.

Requires NHTSA to study and publish guidelines to ensure ADAS and vehicle dynamic systems function after modifications on 2028+ passenger vehicles and requires manufacturers to provide tolerance data.
Introduced December 12, 2025 by Diana Harshbarger · Last progress December 12, 2025
Requires the Department of Transportation (via NHTSA) to produce a study (within 12 months) and publish industry guidelines (within 24 months) to ensure Advanced Driver Assistance Systems (ADAS) and related vehicle dynamic systems on passenger vehicles (model year 2028 and later) continue to function safely after modifications or customization. The rules must define allowable modification ranges and tolerances, provide calibration procedures and confirmatory tests, require manufacturers to supply tolerance/sensitivity data shortly after vehicle release, and allow NHTSA to hire independent labs for testing; manufacturers who fail to comply can face civil penalties.
