Summary

Manufacturers, distributors, dealers, rental companies, and repair shops must not on purpose disable any safety device or design feature that was put in a vehicle to meet federal safety rules. A motor vehicle repair business means a person who advertises or offers to fix vehicles or vehicle parts for pay. They may only make a device inoperative if they reasonably believe the vehicle or equipment will not be used while it is turned off, except for testing or similar use during maintenance or repair. The Transportation Secretary can issue rules to allow some exemptions and to define what “disable” means.
