ADAS Functionality and Integrity Act
Summary
What This Bill Does
The ADAS Functionality and Integrity Act directs the Secretary of Transportation, through NHTSA, to complete a study within 12 months and publish guidelines within 24 months for advanced driver assistance systems and vehicle dynamic systems on passenger vehicles from model year 2028 onward. The guidelines must address allowable modification ranges, ride height, wheel and tire dimensions, static geometry, sensor and camera function, vehicle tolerance information, manufacturer disclosure of system sensitivity within 30 days after release, calibration procedures after repair or modification, confirmatory testing, performance validation metrics, and New Car Assessment Program style scoring. NHTSA may contract with independent labs and testing facilities, and manufacturers that fail to meet the guidelines face civil penalties under title 49.
Who Benefits and How
Vehicle owners and road users benefit from clearer standards that keep ADAS functioning after customization or repair. Independent repair facilities, aftermarket businesses, dealers, independent labs, and vehicle testing facilities benefit from transparent calibration thresholds and potential testing work.
Who Bears the Burden and How
NHTSA staff must run a study, consult industry groups, publish guidelines, contract for testing if needed, and base determinations on empirical data. Passenger vehicle manufacturers and equipment manufacturers must provide tolerance and sensitivity information within 30 days after vehicle release and face civil penalties if they do not meet the guidelines.
Key Provisions
- Requires NHTSA to complete an ADAS modification and tolerance study within 12 months.
- Directs NHTSA to publish ADAS calibration, tolerance, testing, and validation guidelines within 24 months.
- Requires manufacturers to provide vehicle tolerance and system sensitivity information within 30 days after release.
- Subjects noncompliant passenger vehicle or equipment manufacturers to civil penalties.
