After a DOT drug or alcohol violation, drivers based in Naperville 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.
Naperville's CDL workforce: With freight moving along I-90, I-94, I-55, I-80 and I-57 and the Chicago freight hub — the largest rail and trucking interchange in North America anchoring the region's logistics economy, logistics, manufacturing, finance, and food processing around Naperville depend on drivers getting back to compliant, safety-sensitive duty quickly. Illinois drivers submit medical certification to the Secretary of State to keep their CDL valid.
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 Naperville, IL.
