Fully compliant, federally regulated urine drug testing for safety-sensitive transportation employees. Certified collectors, MRO review, and strict chain of custody — every time.
The U.S. Department of Transportation (DOT) requires urine drug testing for all employees in safety-sensitive positions within regulated transportation industries. These regulations are codified in 49 CFR Part 40, which sets the procedures for transportation workplace drug testing programs.
Any employer with DOT-covered employees — including commercial truck drivers, airline crew, railroad workers, transit operators, and pipeline workers — must maintain a compliant drug testing program or face significant federal penalties.
The DOT-mandated test screens for five specific drug categories in urine. Results are reviewed by a federally certified Medical Review Officer (MRO) before being reported.
Note: Alcohol testing is separate from the drug test panel and is conducted via breath alcohol testing (BAT), not urine.
Required before any safety-sensitive employee performs a covered function for the first time. A verified negative result must be on file.
Computer-generated random selection. FMCSA requires 50% drug / 10% alcohol of the covered pool annually. Selection must be truly random.
Required after accidents meeting DOT thresholds (fatality, injury, disabling damage). Strict time limits apply — urine must be collected ASAP.
When a trained supervisor documents specific, contemporaneous observations of behavior, appearance, or speech suggesting drug use.
A verified negative result is required before an employee may return to safety-sensitive duties following a violation.
At least 6 unannounced follow-up tests in the first 12 months post-return-to-duty, continuing up to 60 months per SAP direction.
All DOT collections follow strict federal procedures outlined in 49 CFR Part 40. At Quick Lab Test, our trained collectors ensure every step is followed precisely:
All DOT drug test results are reviewed by a licensed physician serving as an MRO before being reported to the employer. The MRO contacts donors with non-negative results to inquire about legitimate prescription explanations. This protects employees from false positives and ensures regulatory compliance.
