What is the DOT Hours of Service 150-air-mile radius exemption?

The DOT hours-of-service 150-air-mile radius exemption is one of the short-haul exceptions allotted by the FMCSA for commercial drivers subject to hours-of-service regulations. 

Hours-of-service regulations address the maximum amount of time commercial drivers can work in the U.S. The hours-of-service rules dictate safety-related requirements such as how long a driver can drive during a shift, when they must take breaks, and how much time they must take off between shifts.

The 150-air-mile radius exemption states that if drivers are operating within 150 air-miles of their normal reporting location, they’re exempt from hours-of-service regulations, and don’t have to complete daily logs or have supporting HOS reporting documentation.
