The Federal Motor Carrier Safety Administration (FMCSA), as part of the United States Department of Transportation, regulates both the trucking and bus/motor coach industries. As a result, the FMCSA holds motor carriers and drivers directly responsible for meeting all safety standards and regulations. Notably, a major component of these safety requirements involves maintaining a compliant drug and alcohol testing program.

Moreover, the FMCSA, working in conjunction with the Department of Transportation (DOT), requires that all individuals subject to commercial driver’s license (CDL) regulations—along with their employers—strictly follow drug and alcohol testing protocols.

Specifically, drug testing procedures for all DOT-regulated employers and employees are outlined in 49 CFR Part 40. Additionally, each DOT agency enforces its own set of specific rules and regulations that complement Part 40.

Furthermore, the rules cover various aspects such as testing procedures, test frequency, and the types of substances tested.

In particular, Part 382 establishes comprehensive programs designed to prevent accidents and injuries caused by alcohol misuse or controlled substance use by drivers of commercial motor vehicles (CMVs).

Therefore, all FMCSA employers must take the time to thoroughly understand and comply with both Part 40 and Part 382 to ensure full regulatory compliance.
