DOT Drug and Alcohol Testing providers

This page focuses on dot drug and alcohol testing for carriers operating in the United States. Carriers in the United States should check whether a provider understands their fleet type, operating model, deadlines and records before work starts.

Use the listings above to review provider profiles, states served and service categories. For urgent matters, ask what the provider can review first, what records they need, how quickly they can respond and whether the work is handled directly or referred to another specialist.

Questions to ask before choosing a provider

  • Do they handle the exact service the carrier needs, including the relevant FMCSA filing, Clearinghouse task, audit-preparation work, driver qualification record, DOT drug-and-alcohol program requirement, operating-authority filing or permit?
  • Can they support your fleet type, state coverage, operating model and deadline?
  • How will they document the work, share updates and protect access to carrier records?
  • What fees, turnaround times and responsibilities apply before they start?

DOT Compliance Companies is an independent provider platform, not FMCSA or a government service. Carriers should make their own checks before choosing a provider.
