FMCSA Drug and Alcohol Clearinghouse

The FMCSA requires all trucking companies and drivers to enroll in the DOT Clearinghouse.

The purpose of the Clearinghouse is to track drivers who have tested positive for drugs or alcohol, or refused to take a drug and/or alcohol test when required.

FMCSA / DOT Drug and Alcohol Clearinghouse

TCS works with more than 10,000 DOT‐approved FMCSA drug specimen collection sites and alcohol testing technicians. These sites are located across the United States and Canada. Wherever your drivers are operating or wherever your business is located, there is a testing location near your drivers.

Our trained representatives will walk you through the process of setting up your DOT Clearinghouse account. We’ll help you with the registration process from start to finish.

TCS has been awesome!

Started my transport business this year & I can truly say that if it wasn’t for this company & staff, I wouldn’t have made it through the DOT/MC process with any hair on my head!

The awareness to stay ahead of any setbacks would have been overwhelming

I’m a new Owner Operator and getting organized and ready to present myself as a business owner with the awareness to stay ahead of any setbacks would have been overwhelming if the team from TCS had not taken the reigns for me.

The company is a one stop service for USDOT, LLC, and other legal matters

Transportation Compliance Services is the best because their employees I spoke to (3 of them) knew their jobs flawlessly. I am very impressed. It also tells me that the management is top of the line because the employees are very professional. The company is a one stop service for USDOT, LLC, and other legal matters needed for a business. The best phone call I made, and they got me up and running. Thank you.
