Title 49 › Subtitle 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 reviews state laws about commercial motor vehicle safety (trucks, buses, etc.) and decides if a state rule is the same as, weaker than, or stronger/extra compared with federal rules. If it is the same, the state may enforce it. If it is weaker, the state may not enforce it. If it is stronger or additional, the state may enforce it unless the Secretary finds it has no safety benefit, conflicts with the federal rule, or would place an unreasonable burden on interstate commerce. The Secretary can consider how similar laws in other states would add up when judging commerce burdens. States that get funds under section 31104 must send the Secretary a copy of any new safety law or rule immediately after it is passed. Anyone (including a State) can ask the Secretary for a waiver of a decision that blocks enforcement. The Secretary must act quickly and will grant the waiver if it is consistent with the public interest and safe operation of commercial vehicles; the petitioner gets a hearing on the record first. The Secretary must notify a State in writing within 10 days after deciding a law may not be enforced. A person harmed by the Secretary’s decision or a waiver ruling has 60 days to ask a U.S. court of appeals (the D.C. Circuit or the circuit where they live or do business) for review. The Secretary can start a review on the Secretary’s own or after a petition. Note: “Secretary” means the Secretary of Transportation.
