DOT Drug Testing
Stay road-legal and audit-ready. We provide fully compliant DOT drug screening for CDL drivers and other safety-sensitive employees under U.S. Department of Transportation regulations.
49 CFR Part 40 Compliant
Compliant collections, defensible results
DOT testing has strict rules — and getting them wrong can put your operating authority at risk. Our qualified collectors follow every step of the federal process so your results hold up.
When DOT testing is required
- Pre-employment, before a driver performs safety-sensitive duties
- Random testing throughout the year
- Reasonable suspicion / for-cause situations
- Post-accident testing within required time windows
- Return-to-duty and follow-up testing
