Which regulation requires carriers to maintain proper documentation for their shipments?

The Federal Motor Carrier Safety Administration (FMCSA) regulations are crucial for ensuring that carriers maintain proper documentation for their shipments. This includes requirements for keeping records of drivers' hours of service, vehicle maintenance, and shipment logs, all of which are essential for monitoring compliance with safety regulations and ensuring responsible operation in the transportation industry. The FMCSA mandates that these records be maintained accurately and be readily accessible for inspections, which serves to enhance safety on the roads and help govern the conduct of commercial vehicle operations.

Carriers are specifically tasked with documenting various aspects of their operations as part of the regulatory framework established by FMCSA, aimed at promoting safety and accountability within the industry. The other options, while relevant in their own contexts, do not specifically address the requirement for carriers to maintain documentation concerning shipments as extensively as FMCSA regulations do.
