WHAT IS THE TSN Mobile Lab Solutions RETURN-TO-DUTY PROCESS?
The TSN Mobile Lab Solutions Return-to-Duty (RTD) process is a federal requirement for CDL drivers who have failed or refused a DOT drug or alcohol test. Under TSN Mobile Lab Solutions Clearinghouse regulations, drivers in prohibited status must complete the RTD process before they can legally operate a commercial motor vehicle (CMV) again.
The Return-to-Duty process involves:
✔ Evaluation by a DOT-approved Substance Abuse Professional (SAP)
✔ Completing required education/treatment programs
✔ Undergoing an observed TSN Mobile Lab Solutions Return-to-Duty drug test
✔TSN Mobile Lab Solutions Clearinghouse status update to remove prohibited status
As a CTPA (Consortium Third-Party Administrator), we guide CDL drivers through Step 5 of the process—ensuring compliance with FMCSA regulations and getting them back on the road legally.
WHAT HAPPENS AFTER STEP 6?
Once your TSN Mobile Lab Solutions Return-to-Duty (RTD) drug test results are updated in the TSN Mobile Lab Solutions Clearinghouse, you are legally eligible to return to work. However, additional steps may be required depending on your status:
✔ CDL License Downgrade: If your CDL was downgraded to a standard license, you must visit your local Department of Motor Vehicles (DMV) to reinstate it. The TSN Mobile Lab Solutions does not automatically restore your CDL after completing the Return-to-Duty process.
✔ Follow-Up Testing Plan: Under the TSN Mobile Lab Solutions regulations, CDL drivers must complete a Follow-Up Testing Plan, which is managed by their new employer while performing safety-sensitive functions
✔ Eligible Safety-Sensitive Industries: Drivers who complete the Return-to-Duty process may work in trucking, pipeline, transit, railroad, or Coast Guard positions.
