Title 49 › SUBTITLE VI — MOTOR VEHICLE AND DRIVER PROGRAMS › PART B — COMMERCIAL › CHAPTER 311 — COMMERCIAL MOTOR VEHICLE SAFETY › SUBCHAPTER III — SAFETY REGULATION › § 31151
The Secretary of Transportation must run a program to keep trailers and chassis used with shipping containers safe and properly maintained. The program will be part of the federal motor carrier safety rules. It must make sure each piece of equipment is tied to a specific provider and has a unique ID, require those providers to inspect, repair, and keep maintenance records, and require drivers to do a short visual or audible check of certain parts before driving. Places that regularly hand off equipment must have space and a process to get defects fixed or the equipment replaced before departure. The program must include audits, a civil penalty system for poor compliance, a ban on using equipment that poses an immediate danger, ways for carriers and providers to ask the agency to investigate alleged violations, and a way for drivers or carriers to report damage when equipment is returned and have that damage fixed and recorded before reuse. DOT staff may inspect equipment and records on demand. Unsafe equipment can be put out of service until repaired. State rules that conflict with these federal rules are preempted, but a State inspection rule in effect on January 1, 2005 may stay in force only until the federal rules take effect unless the State asks to keep it and the Secretary finds it equally effective and not an undue burden; the Secretary must decide within 6 months, and any later changes to that State rule need prior approval. Defined terms: intermodal equipment — trailers and chassis used to move shipping containers on public highways; intermodal equipment interchange agreement — a written contract that sets responsibilities for exchanged equipment; intermodal equipment provider — a person or company that supplies or must maintain that equipment; interchange — giving equipment to a motor carrier for loading, unloading, transport, or repositioning (not long-term leasing for a carrier’s main freight work).
