Stay in the Know: DOT Proposes Fentanyl Testing for Safety-Sensitive Transportation Workers
The U.S. Department of Transportation has proposed adding fentanyl (and its metabolite norfentanyl) to mandatory drug-testing panels for safety-sensitive roles across trucking, aviation, maritime, transit, and more.
What this means:
• Tests in both urine and oral fluid for fentanyl; norfentanyl in urine
• DOT aligning with HHS standards under a proposed update to 49 CFR Part 40
• Employers will need new lab capabilities, policy updates, and worker disclosure
• Public feedback on the proposal is open until October 17, 2025
Why it matters:
• Strengthens the response to the fentanyl overdose crisis
• Enhances workplace safety in industries where impairment carries high risks
