How do I know what drivers to include in my drug pool?
Generally, all CDL drivers who operate commercial motor vehicles are subject to DOT drug and alcohol testing (§382.103). This includes all full-time, part-time, intermittent, backup and international drivers.
If you are required to or choose to test non-CDL drivers, they must be in a separate pool from your CDL drivers.
