Title 49 › Subtitle SUBTITLE IV— INTERSTATE TRANSPORTATION › Part B— MOTOR CARRIERS, WATER CARRIERS, BROKERS, AND FREIGHT FORWARDERS › Chapter 145— FEDERAL-STATE RELATIONS › § 14501
Federal rules stop states and local governments from making their own laws that control how interstate motor carriers run passenger or freight services. States may not set schedules, force changes in routes, limit the authority to run charter bus service, or control prices and routes for brokers and freight forwarders. One rule allows states to require up to 30 days’ notice for schedule changes. Several safety and road rules still belong to the states: they can enforce vehicle safety, set highway route limits based on size, weight, or hazardous cargo, and require insurance or self‑insurance. The State of Hawaii is mostly exempt from some of these federal limits. States also cannot set rules about prices, routes, or services for property haulers, with a few exceptions. States may keep uniform cargo paperwork and liability rules that are no tougher than federal rules and that apply only when a carrier asks. States can regulate intrastate household goods and tow‑away operations done without the vehicle owner’s consent (and may require written owner authorization or the owner’s presence). For pre‑arranged interstate ground transportation, states cannot charge extra licenses or fees if the carrier meets federal registration and state vehicle rules and is operating under an interstate contract. Taxicabs are not covered, terminals may give special access deals, and states may require nondiscriminatory pre‑licensing drug or background checks.
