Frequently Asked Questions All FAQs

Safety-sensitive employees regulated by FMCSA, FAA, FTA, FRA, PHMSA, and USCG must participate in DOT testing programs according to 49 CFR Part 40 and modal regulations.

Testing typically includes pre-employment, random, post-accident, reasonable suspicion/cause, return-to-duty, and follow-up. Alcohol testing (including breath alcohol testing) applies in specified circumstances.

A consortium/TPA manages your random selections, recordkeeping, and compliance tasks. Owner-operators and many small employers enroll to meet random testing requirements efficiently.

Negative drug test results are often available within 1-2 business days. Non-negative results and alcohol positives require MRO review, which can extend turnaround time.

DOT agencies publish annual random testing rates. Selections are computer-generated to ensure an unpredictable spread across the selection period.

Refusals include behaviors such as not appearing, leaving the site, failing to provide a specimen, adulterating/substituting, or not following instructions. Consequences mirror a positive result.

An MRO reviews lab results and contacts the employee. If a violation is confirmed, the individual must be evaluated by a SAP and complete return-to-duty and follow-up testing requirements.

Retention periods vary by record type (e.g., 5 years for positive results and refusals). We maintain audit-ready documentation per DOT requirements.
