Title 49 › Subtitle SUBTITLE VI— MOTOR VEHICLE AND DRIVER PROGRAMS › Part A— GENERAL › Chapter 301— MOTOR VEHICLE SAFETY › Subchapter I— GENERAL › § 30103
The Secretary of Transportation cannot make a safety rule for a motor vehicle covered by subchapter I of chapter 135 that conflicts with the federal motor vehicle safety standards in this chapter. The Secretary can, however, require a higher performance standard after the vehicle is made for vehicles run by carriers under subchapter I of chapter 135. When a federal safety standard is in effect, a State or local government may only have a rule about the same safety issue if it is exactly the same as the federal rule. The U.S. Government, a State, or a local government may impose a tougher standard for vehicles it buys for its own use, and a State may enforce a state rule that matches the federal standard. The chapter does not change antitrust law: it does not make illegal conduct legal or make legal conduct illegal. Sections 30117(b), 30118–30121, 30166(f), and 30167(a) and (b) do not create or change warranty duties under federal or state law. Remedies under those sections and under sections 30161 and 30162 are extra rights in addition to other legal remedies. Following a federal motor vehicle safety standard does not free someone from common-law liability.
