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 Administration’s (FMCSA) require alcohol and drug testing of drivers, who are required to have a California Driver’s 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 driver’s license (CDL).
Examples of drivers and employers subject to these rules are:
- Anyone who owns or leases commercial motor vehicles

- Federal, state and local governments
