What it does
This bill requires the Department of Transportation to develop safety guidelines within 24 months for how much car owners and repair shops can modify vehicles with advanced driver assistance systems (ADAS) — like lane-keeping and collision-avoidance — without breaking those safety features. It mandates that manufacturers share tolerance information with owners, establishes calibration and testing standards, and makes manufacturers liable for violations. The bill also requires a 12-month study assessing feasibility and cost.
Why we flagged it
The bill's core mechanism is establishing transparent safety guidelines for vehicle modification and repair, with mandatory manufacturer disclosure and independent testing protocols. It functions as a consumer protection and right-to-repair measure, not as a subsidy, carve-out, or deregulation.
What the text implies
- Manufacturers must disclose proprietary sensor calibration data and tolerance thresholds to owners and repair shops, potentially reducing their competitive advantage in aftermarket service pricing.
- Independent repair facilities and aftermarket shops gain legal standing to perform ADAS calibration and testing, directly competing with manufacturer-authorized service centers.
