Title 49 › SUBTITLE VI — MOTOR VEHICLE AND DRIVER PROGRAMS › PART B — COMMERCIAL › CHAPTER 311 — COMMERCIAL MOTOR VEHICLE SAFETY › SUBCHAPTER III — SAFETY REGULATION › § 31141
The Secretary of Transportation must review State laws and rules about commercial motor vehicle safety and decide if each one matches, is weaker than, or is stronger than the federal rule under section 31136. If a State rule has the same effect as the federal rule, the State may enforce it. If it is less strict, the State may not enforce it. If it is extra or more strict, the State may enforce it unless the Secretary finds no safety benefit, finds it conflicts with the federal rule, or finds it would place an unreasonable burden on interstate commerce. When deciding about burdens, the Secretary may look at how that rule would work together with similar rules in other States. A State that gets funds under section 31104 must send a copy of any new truck-or-bus safety law or rule to the Secretary right away. If the Secretary decides a State rule may not be enforced, the Secretary must send the State written notice within 10 days. Anyone, including a State, can ask for a waiver of that decision. The Secretary must act quickly on a waiver if it is consistent with the public interest and safe vehicle operation, and must give the petitioner a hearing on the record first. Within 60 days of the Secretary’s decision or of a waiver grant or denial, an affected person can ask a U.S. court of appeals (the D.C. Circuit or the circuit where they live or have their main business) to review the action. The court can grant relief under chapter 7 of title 5, and Supreme Court review is under section 1254 of title 28. The Secretary may start reviews on the Secretary’s own or after a petition.
