What does the term "HOS" refer to in commercial vehicle operation?

The term "HOS" stands for "Hours of Service," which is a set of regulations established by the Federal Motor Carrier Safety Administration (FMCSA) to govern the working hours of anyone operating a commercial motor vehicle. These regulations are crucial for ensuring safety on the roads by limiting the number of hours that a driver can operate a vehicle without taking mandatory rest breaks.
