What Is 49 CFR Part 40?
49 CFR Part 40 is the federal regulation that establishes the procedures for conducting workplace drug and alcohol testing for safety-sensitive transportation employees.
Rather than applying to just one transportation agency, Part 40 provides the testing procedures that are used across multiple U.S. Department of Transportation (DOT) agencies. These procedures help ensure that drug and alcohol testing is conducted consistently, fairly, and accurately.
For specimen collectors, following these procedures helps maintain the integrity of every collection and supports a reliable testing process.
