The Federal Motor Carrier Safety Administration (FMCSA), along with the Department of Transportation (DOT), requires that persons subject to the commercial driver’s license (CDL) requirements and their employers follow alcohol and drug testing rules. These rules include procedures for testing, frequency of tests, and substances tested for.

    
    
      
      Who's Impacted?

Anyone employing CDL drivers to operate commercial motor vehicles (CMVs) on public roads
	CDL drivers who operate CMVs on public roads
	Interstate motor carriers
	Intrastate motor carriers
	Federal, State, and local governments
	Civic organizations (disabled veteran transport, boy/girl scouts, etc.)
	Faith-based organizationsResources for Drivers*

While it is the responsibility of your employer to provide you with information on drug and alcohol testing programs, it is still ultimately your responsibility to obey all rules and regulations in order to keep our roadways safe. Drivers of CMVs can learn about drug and alcohol rules, types of tests required and their rights, responsibilities and requirements here.

Resources for Employers*

As an employer, you have a responsibility to implement and conduct drug and alcohol testing programs. Learn about drug and alcohol rules and how they affect your business here.

*An employer who employs himself/herself as a driver must comply with requirements of 49 CFR Part 382 that apply to both employers and drivers.

Resources for Service Agents

Service agents that administer drug and alcohol tests can find general information and other resources here.

Guidance on Drug and Alcohol Supervisor Training
