§382.309 sets the return-to-duty test requirement. After a positive test, refusal, or any other §382.211–§382.215 violation, the driver may not perform safety-sensitive functions until a Substance Abuse Professional (SAP) has evaluated the driver under 49 CFR §40 Subpart O and the driver has passed a return-to-duty test administered under direct-observation per §40.67. The carrier may not arrange the test until the SAP has determined the driver is ready.
Severity weight + Clearinghouse
Severity weight 10 in the Controlled Substances & Alcohol BASIC. The Clearinghouse "prohibited" status remains until the return-to-duty test is reported negative — there is no workaround. The carrier that returns a driver to duty without a negative §382.309 test takes a separate §382.215 carrier-side citation.
What the carrier must do
- Provide the driver with the names and contact information of available SAPs (the §40.281 list).
- Do not arrange the test before the SAP signs off on readiness.
- The test must be a direct-observation collection (§40.67) — same-gender observer, all the §40.67(g) protocol steps.
- Report the negative return-to-duty test to the Clearinghouse within the §382.705 timeframes.
Follow-up flows from here
A negative §382.309 test only returns the driver to duty; it does not end the process. §382.311 follow-up testing (minimum six tests over the first 12 months back, per the SAP's plan) is the next phase and continues for up to 5 years.
How Roadworthy HQ helps
Roadworthy HQ tracks the SAP referral, the SAP-determined readiness date, the return-to-duty test result, the Clearinghouse status change, and the §382.311 follow-up schedule as discrete linked items in the driver's D&A record.
