After a DOT drug or alcohol violation, Missouri drivers 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.
Missouri's CDL workforce: With freight moving along I-70, I-44, I-55, I-29 and I-35 and the St. Louis and Kansas City freight hubs at the center of the national network anchoring the state's logistics economy, Missouri's logistics, manufacturing, agriculture, and healthcare sector depends on drivers getting back to compliant, safety-sensitive duty quickly. Missouri’s dual freight hubs make it one of the busiest CDL states in the Midwest.
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 Missouri.
A minimum of 6 unannounced tests over the next 12 months, as set by the SAP.
Return-to-duty and follow-up tests can be completed at any certified site in our network, including locations near:
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 Missouri site.
WorkOccMed reports return-to-duty and follow-up test results to the FMCSA Clearinghouse on your behalf as your 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.
