If you’ve been prohibited from performing safety-sensitive functions due to a drug or alcohol program violation, completing the Return-to-Duty (RTD) process is your pathway back to compliance. This process is outlined in 49 CFR Part 40, Subpart O, and ensures that drivers meet the safety standards required by the DOT.
Step 1: Send Request to Substance Abuse Professional (SAP)
A driver with a verified drug and alcohol program violation is prohibited from performing safety-sensitive functions until the RTD process is complete.
The employer provides the driver with a list of DOT qualified SAPs, as required by § 40.287. The driver selects their SAP from this list or based on their own research.
The driver requests the SAP through the Clearinghouse online.
Step 2: SAP Designated
The SAP approves the request in the Clearinghouse portal.
Client schedules an initial evaluation.
The designated SAP initially evaluates the driver.
Step 3: Initial SAP Assessment Completed
The SAP provides the employer with recommendations for education/treatment.
After the driver completes the education/ treatment, the SAP re-evaluates the driver to determine compliance and establish a follow-up testing plan.
Step 4: Driver Determined Eligible for RTD Test
The driver must be sent for an RTD test by his or her current employer.
*In the case of an owner-operator, these steps must be completed by a designated C/TPA.
Step 5: RTD Test with Negative Result
The driver is no longer prohibited from performing safety-sensitive functions once they have a negative RTD test result.
Any employer that employs this driver during the prescribed period must complete the follow-up testing plan as specified by the SAP.
*In the case of an owner-operator, these steps must be completed by a designated C/TPA.
Step 6: Follow-Up Testing Plan Completed
This information is retained in the Clearinghouse for five years from the date of the violation determination or until the successful completion of the follow-up testing plan, whichever is later.
