The formula to calculate the Hours of Service is:
\[ H_s = H_t - B \]
Where:
Let's say a driver worked for 10 hours and took a 1-hour break. The hours of service would be calculated as follows:
\[ H_s = 10 - 1 = 9 \]
So, the hours of service are 9 hours.
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.
