49 CFR, or Title 49 of the Code of Federal Regulations, is a set of rules established by the U.S. government to regulate transportation safety and operations across various modes such as highway, rail, air, and maritime. It includes requirements for vehicle safety, hazardous materials handling, driver training, and transportation security.
