Do I need to track Hours of Service for my non-CDL drivers?

Any driver that leaves the state or goes to the airport in a vehicle designed for 9 of more passengers is an interstate commercial motor vehicle operator.  These driver are subject to the same Hours of Service regulations as a CDL driver. That means you are responsible for ensuring compliance with the 70-hour 8-day or 60-hour 7-day rules; including non-driving time for other employers.  You must also ensure these drivers do not exceed the daily hours of service regulations for passenger carriers.
