Federal regulations in the United States limit the number of hours a commercial truck driver can operate a vehicle within a given period. These limitations, enforced by the Federal Motor Carrier Safety Administration (FMCSA), are designed to prevent driver fatigue and enhance road safety. A driver’s daily driving limit is directly tied to their hours-of-service regulations, rather than a specific mileage cap. These regulations dictate that a driver may drive a maximum of 11 hours after 10 consecutive hours off duty. This means that the actual distance covered in a day can vary considerably depending on factors such as traffic conditions, speed limits, and route specifics. For instance, a driver encountering heavy traffic will cover significantly fewer miles than one driving on a relatively open highway.
Regulations governing driver hours and consequently, potential daily mileage, are crucial for public safety. Driver fatigue is a recognized contributor to accidents, and these rules help mitigate that risk. The historical context of these regulations reveals a growing understanding of the physiological impacts of long hours behind the wheel and a societal commitment to reducing accidents caused by drowsy driving. These rules help create a fairer and more competitive transportation industry, ensuring drivers are not pressured to drive beyond safe limits to meet unrealistic delivery schedules.
