After a DOT drug or alcohol violation, drivers based in Houston 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.
Houston's CDL workforce: With freight moving along I-35, I-10, I-45, I-20 and I-30 and the I-35 NAFTA corridor, the Ports of Houston and Laredo, and the nation’s largest network of truck freight anchoring the region's logistics economy, energy, logistics, construction, and manufacturing around Houston depend on drivers getting back to compliant, safety-sensitive duty quickly. Texas CDL drivers submit their Medical Examiner’s Certificate to the DPS/DMV to stay certified.
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 Houston, TX.
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 Texas, 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 Houston.
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.
