What is Hours of Service?

Hours of Service (HOS) regulations are designed to prevent accidents caused by driver fatigue. These regulations specify the maximum number of hours a driver can work and drive, as well as the minimum amount of rest they must take. The goal is to ensure that drivers are well-rested and alert, thereby improving road safety. HOS regulations are particularly important in industries such as trucking and transportation, where long hours on the road are common.
