Correct testing reason matters
DOT tests are not interchangeable. The testing order must identify the correct regulatory reason, and some services have special timing, observation, or documentation requirements. Contact us before sending a driver to a collection site when the correct test is unclear.
Coordinate the required controlled-substances test before a covered CDL driver first performs a safety-sensitive function for an employer.
Arrange testing after a driver is selected through an employer or consortium random pool. Selected drivers must follow the applicable instructions and timeline.
Request time-sensitive coordination after an accident that may satisfy FMCSA post-accident testing criteria. Employers remain responsible for determining whether the rule applies.
Coordinate testing after a trained supervisor documents specific, contemporaneous observations supporting the determination.
Schedule a direct-observation test after the driver completes the required substance abuse professional process and becomes eligible to test.
Arrange direct-observation follow-up tests according to the plan established through the return-to-duty process.
