After a DOT drug or alcohol violation, drivers based in Chattanooga must complete a SAP evaluation, a negative return-to-duty test, and a follow-up testing plan before resuming safety-sensitive duties. WorkOccMed coordinates the whole process.
A DOT drug or alcohol violation — including a positive test, refusal, or FMCSA Clearinghouse flag — prohibits a CDL driver from performing safety-sensitive functions until the full return-to-duty process is complete.
Chattanooga's CDL workforce: With freight moving along I-40, I-24, I-65 and I-75 and the Memphis logistics hub — home to the FedEx global superhub — and the Nashville freight corridor anchoring the region's logistics economy, logistics, healthcare, automotive, and music around Chattanooga depend on drivers getting back to compliant, safety-sensitive duty quickly. Tennessee’s Memphis hub makes it one of the most important logistics states in the nation.
A Substance Abuse Professional evaluates the driver and recommends education or treatment.
The driver completes the SAP's recommended program.
The SAP confirms compliance and clears the driver for return-to-duty testing.
A negative, directly-observed test at a certified site near the driver in Chattanooga, TN.
A minimum of 6 unannounced tests over the next 12 months, as set by the SAP.
WorkOccMed coordinates return-to-duty and follow-up testing across Tennessee, including:
It varies by driver — the SAP's recommended education or treatment sets the pace. Once cleared, the return-to-duty test itself can typically be scheduled same-day at a certified site in Chattanooga.
WorkOccMed reports return-to-duty and follow-up test results to the FMCSA Clearinghouse on your behalf as your C/TPA.
We coordinate with SAPs and manage the paperwork, records release, and testing logistics; the SAP evaluation itself is performed by a qualified, independent Substance Abuse Professional.
