The Total Transportation Consortium

Houston Medical Testing Services (HMTS) has one of the largest and oldest FMCSA trucking consortiums for over 25 years, currently with over 2,000 members throughout the United States. As a winner of the Better Business Award for Excellence for years 2015, 2016, and 2017, HMTS is very proud of the fact that in 25 years of operating the Total Transportation Consortium (TTC), no client ever has been fined by the FMCSA for a substance abuse program violation. Overall HMTS maintains an excellent relationship with the many FMCSA auditors and works relentlessly with the clients and FMCSA to keep the clients in full compliance with their mandated substance abuse programs.

With HMTS, client is too small or too big to become a member of the TTC, Membership fees are based upon a sliding scale depending upon the number of drivers. For example, 1 to 3 drivers costs the member company only $144.00 per year, while the next scale is for companies with 4-12 drivers and so on. The Annual membership fee provides the client company with a DOT approved written substance their required DOT physical exam if needed, a pre-employment drug test in conducted and the driver’s membership, so in most cases if a driver is stopped on the road, all the driver must do is show the enforcement authority their consortium membership card indicating that the driver is in full compliance. On randoms, if a driver is selected, the TTC manger contacts the client company representative with the information of where the driver needs to report. HMTS maintains a database of over 4,000 approved collection sites throughout the country, so getting a driver tested at a convenient location within a reasonable time frame is never an issue.

We encourage you to contact Houston Medical Testing Services and learn more about its very successful and federal compliant FMCSA consortium, by calling out main office at 713-665-4687 or 1-800-568-8065.
