DOT vs. Non-DOT Drug Testing: What Maryland Employers Need to Know

If your company employs safety-sensitive transportation workers — truck drivers, transit operators, pilots — you are likely subject to U.S. Department of Transportation (DOT) drug and alcohol testing rules under 49 CFR Part 40. These rules are strict and federally mandated.

DOT testing uses a specific 5-panel urine test, requires certified collectors, mandates a Medical Review Officer (MRO) to verify any non-negative result, and follows exact procedures for collection, forms, and timelines. There is very little flexibility.

Non-DOT testing is for everyone else — private employers who set their own workplace policy. You have more flexibility in panel size (5, 9, 10, or more), specimen type (urine, oral fluid, hair), and program design. The trade-off is that you are responsible for a clear, consistent, legally sound policy.

In both cases, SafeTouch Enterprise provides the collection: certified, compliant, and documented with chain-of-custody. The accredited laboratory performs the analysis and reports results through the MRO (for DOT) or to your designated contact (for non-DOT).
