DOT drug and alcohol testing is a federally mandated program that ensures all safety-sensitive transportation employees remain drug-free and fit for duty. Required under 49 CFR Part 40 and enforced by the Department of Transportation (DOT), these tests are designed to protect drivers, fleets, and the public by preventing substance-related incidents on the road.

At Safety Hub, we specialize in helping carriers and fleet operators stay compliant with every DOT testing regulation. Our comprehensive drug testing service covers all stages of employment and operation — including pre-employment, post-accident, random drug testing, reasonable suspicion, return-to-duty, and follow-up testing.

Each test is conducted through certified laboratories, ensuring accuracy, confidentiality, and full adherence to DOT and Transport Canada guidelines. We manage all aspects of your testing program — from scheduling and employee notifications to result tracking and documentation — so you can focus on running your business confidently.

Maintaining a compliant drug and alcohol testing program not only helps avoid penalties and out-of-service orders but also improves your safety rating, lowers insurance risks, and demonstrates your commitment to road safety and professionalism.

With Safety Hub, you get a reliable partner who understands both U.S. and Canadian compliance frameworks — ensuring your fleet operates safely, legally, and efficiently on every mile.
