After a DOT drug or alcohol violation, Colorado 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.
Colorado's CDL workforce: With freight moving along I-25, I-70 and I-76 and the I-70 mountain freight corridor and the Denver logistics hub anchoring the state's logistics economy, Colorado's construction, energy, aerospace, and distribution sector depends on drivers getting back to compliant, safety-sensitive duty quickly. Colorado’s mountain routes place added emphasis on driver fitness and DOT medical standards.
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 Colorado.
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 Colorado 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.
