Drug and Alcohol Screening for Driving Classifications

The Omnibus Transportation Employees Testing Act of 1991 requires drug and alcohol testing of safety-sensitive transportation employees in aviation, trucking, railroads, mass transit, pipelines and other transportation industries. The Department of Transportation (DOT) publishes rules on who must conduct drug and alcohol tests, how to conduct those tests, and what procedures to use when testing. These regulations cover all transportation employers, safety-sensitive transportation employees, and service agents (roughly 100 million people).

Alcohol and Drug Rules

The Federal Motor Carrier Safety Administrationís (FMCSA) require alcohol and drug testing of drivers, who are required to have a California Driverís License (CDL). The DOT rules include procedures for urine drug testing and breathe alcohol testing.

Who is affected by these rules?

The FMCSA rules apply to safety-sensitive employees, who operate commercial motor vehicles requiring a commercial driverís license (CDL).

Examples of drivers and employers subject to these rules are:

  • Anyone who owns or leases commercial motor vehicles
  • Anyone who assigns drivers to operate commercial motor vehicles
  • Federal, state and local governments
  • For-hire motor carriers
  • Private motor carriers
