## Summary

**Keep ADAS working after vehicle modifications.** This bill would require the Department of Transportation, through NHTSA, to publish guidelines within 24 months so advanced driver assistance systems and vehicle dynamic systems maintain functionality when passenger vehicles are modified or customized. - Owners and modifiers would get quantifiable tolerance thresholds, calibration procedures, and confirmatory test protocols to verify ADAS operation after repairs or changes. Manufacturers must provide vehicle tolerance and system sensitivity information to owners and the Administrator within 30 days of a new model's release. - Manufacturers would need to publish allowable modification ranges, system sensitivity data, and proper post-repair calibration steps across vehicle platforms. Violations of the guidelines could lead to civil penalties under 49 U.S.C. § 30165(a). - The Administrator may contract with independent laboratories and testing facilities to develop empirical test methods. The bill requires a 12-month study on feasibility, capability, and costs to support ADAS functionality for model years after 2028 and mandates stakeholder outreach and a U.S. NCAP-style scoring scale for calibration validation.
