Whether your travel time is work time depends upon the kind of travel involved. Normal travel from home to work is not work time. Time spent by an employee in travel as part of his principal activity, such as travel from job site to job site during the workday, must be counted as hours worked. Travel that keeps an employee away from home overnight is travel away from home.
Travel time as overtime
If you add your travel time and work time exceeds 40 hours a week, you get overtime pay.
An employee who has gone home after completing his day’s work and is subsequently called out at night to travel a substantial distance to perform an emergency job for one of his employer’s customers all time spent on such travel is working time. Where an employee is required to report at a meeting place to receive instructions or to perform other work there, or to pick up and to carry tools, the travel from the designated place to the work place is part of the day’s work, and must be counted as hours worked regardless of contract, custom, or practice
If an employee normally finishes his work on the premises at 5 p.m. and is sent to another job which he finishes at 8 p.m. and is required to return to his employer’s premises arriving at 9 p.m. , all of the time is compensable time.
