The gist

Forces the National Highway Traffic Safety Administration (NHTSA) to write rules ensuring car safety tech keeps working after vehicles get lifted, repaired, or customized starting model year 2028.

Who wins, who loses

Wins: independent repair shops, car modification customers, drivers sharing roads with lifted trucks.

Loses: automakers facing new disclosure rules and possible fines; aftermarket parts makers if modifications get restricted.

What it does

Gives NHTSA 24 months to publish guidelines on ride height, tire size, and sensor placement limits.

Requires automakers to share tolerance and sensitivity data with owners within 30 days of a new model's release.

Creates a good/fair/poor scoring scale for calibration, building on the New Car Assessment Program (NCAP).

Applies civil penalties under federal law to manufacturers who ignore the guidelines.

Why should I care?

Teen drivers share roads with modified trucks and SUVs every day. Supporters say standardized rules close a dangerous gap where lifted vehicles roll around with broken automatic braking nobody knows about. Critics argue federal modification limits could hurt the aftermarket industry and car enthusiasts' freedom to customize. Where do you land?
