Transportation regulation refers to the rules and laws that govern how transportation systems operate. These regulations are designed to ensure safety, efficiency, and fairness in the movement of people and goods. They can cover various modes of transport, including airlines, trucking, railroads, and public transit. Regulatory bodies, such as the Federal Aviation Administration (FAA) for air travel and the Federal Motor Carrier Safety Administration (FMCSA) for trucking, enforce these regulations. They set standards for vehicle safety, driver qualifications, and operational practices to protect the public and maintain a reliable transportation network.
