I hold a commercial driver's license (CDL). Am I subject to the controlled substance and alcohol testing rules?
Yes. This includes the following:
  • Federal, State, Local and tribal governments
  • Church and civil organizations
  • Farmers and custom harvesters
  • Apiarian Industries
  • For-hire and private companies
Note that the drug and alcohol testing requirements are only required when you operate a vehicle that requires a CDL. An individual can ‘hold’ a CDL for years and not need to be in a drug and alcohol program until they actually operate a commercial motor vehicle.
