DOT Workplace Drug and Alcohol Testing Procedures

Current understanding

The Department of Transportation regulates drug and alcohol testing procedures for safety-sensitive transportation workers (e.g., commercial drivers, pilots, transit operators, pipeline and maritime workers). A 2026 revision requires directly observed urine collection when oral fluid testing is unavailable, and updates rule terminology to conform with Executive Order 14168 on federal usage of sex-based terms. Practical effect on workers includes expanded circumstances triggering observed collection (a more intrusive procedure) and altered rules for observer-employee sex matching under revised terminology.
