Employers of safety-sensitive transportation employees play a vital role in ensuring the safety of their employees and the traveling public. Employers are responsible for developing and implementing successful DOT workplace drug and alcohol programs that have as their components clear policies, provisions for education and training, drug and alcohol testing, and when needed, referral for evaluation and treatment.

DOT regulated employers must comply with 49 CFR Part 40 and applicable DOT Agency regulations. Find out if you are covered under the DOT program by going to: Am I Covered?

If you are considered a covered employer, you should know about the regulations, guidelines, and supporting publications.
