You and your SAP
You attend appointments and follow recommendations. Your SAP evaluates your progress and provides the required reports and follow-up testing plan.

The DOT SAP program and return-to-duty steps
Your SAP, your employer and you each have a part to play. Here is what to expect at every stage.
Before you begin
Once an employer knows of a DOT drug or alcohol violation, the driver must be removed from safety-sensitive functions. The employer must provide a list of readily available DOT-qualified SAPs acceptable to the employer, even if the driver is fired or was only an applicant. The employer cannot charge for providing the list.
Find and designate your SAP.
The driver contacts a DOT-qualified SAP, establishes a relationship with that SAP and sends a designation request through the Clearinghouse. The SAP must accept the designation before entering the driver's return-to-duty information. Once the driver has been evaluated by a SAP, 49 CFR 40.295 prohibits seeking a second SAP evaluation in order to obtain another recommendation.
Request pricing from up to 4 SAPsAttend your SAP assessment.
The SAP conducts a clinical assessment and determines what education, treatment or both the driver must complete. The evaluation may be conducted in person or remotely when the Part 40 requirements for real-time audio and video and the SAP's credential requirements are met. Every driver who has a DOT violation must receive an individualized recommendation. The SAP records the required assessment information in the Clearinghouse.
Follow the education or treatment plan.
The driver completes the education, treatment or both prescribed by the SAP. There is no standard DOT course, number of counseling sessions or fixed treatment period for every driver. The recommendation must be based on the individual evaluation. A driver cannot shop for a second SAP evaluation simply to obtain an easier recommendation.
Return to your SAP for review.
The SAP evaluates the driver again and determines whether the driver has demonstrated successful compliance with the original recommendations. If the driver has, the SAP provides the required written report and records the driver's eligibility for return-to-duty testing in the Clearinghouse. This does not yet change the driver's status to not prohibited.
Complete the required RTD test.
A current or prospective employer normally directs the applicable DOT return-to-duty test after the SAP has found successful compliance. A DOT drug return-to-duty collection is conducted under direct observation. The driver must receive the required negative drug result and/or, when applicable, an alcohol result below 0.02 before returning to safety-sensitive functions. The responsible employer or authorized C/TPA reports the negative RTD result to the Clearinghouse. That is the point at which the driver's Clearinghouse status changes from prohibited to not prohibited.
Continue with follow-up testing.
Once the driver returns to safety-sensitive work, the employer must carry out the SAP's follow-up testing plan. The plan requires at least six unannounced tests during the first 12 months of safety-sensitive duty and can continue for as long as 60 months. The employer chooses the actual test dates without giving the driver advance notice. The testing obligation follows the driver to later DOT employers and through breaks in service.

Who does what: driver, SAP and employer
Knowing who handles each part makes it easier to ask the right questions.
Your employer or C/TPA
Your employer arranges the required testing and implements the SAP’s follow-up plan. Owner-operators work with their designated C/TPA.
Read employer responsibilitiesEmployers: provide a SAP list
DOT rules require a list of readily available, acceptable SAPs for employees or applicants with a violation. You cannot charge the individual for the list.

Owner-operators and drivers between jobs
An owner-operator who employs themselves as a CDL driver is subject to both driver and employer responsibilities and must designate a C/TPA as required by the Clearinghouse rules.
A driver who loses a job can still complete the SAP evaluation, education or treatment and follow-up evaluation while unemployed. There is also an FMCSA procedure for a driver who has no current or prospective Part 382 employer willing to arrange the RTD test. The driver may register in the Clearinghouse with the owner-operator role and designate a C/TPA for the limited purpose of directing the RTD test and reporting the negative result.
That procedure does not make the C/TPA the driver's future employer and does not eliminate follow-up testing. When the driver later returns to a DOT safety-sensitive position, the employer is responsible for administering the SAP's follow-up testing plan. Owner-operators who need ongoing program administration can compare a DOT drug and alcohol consortium.
Where the process usually stalls
- The driver contacts a SAP but never completes the Clearinghouse designation, or the SAP has not accepted it.
- The person performing the evaluation does not actually meet the DOT SAP qualification requirements.
- The driver completes only part of the education or treatment and cannot demonstrate successful compliance at the follow-up evaluation.
- The SAP records RTD eligibility, but nobody arranges the actual DOT return-to-duty test.
- The driver assumes RTD eligibility means prohibited status has already ended. It has not. The required negative RTD result still has to be reported.
- A driver's CDL or CLP was downgraded while prohibited and the driver assumes a not prohibited Clearinghouse status automatically restores the commercial driving privilege.
- The driver changes employers and the new employer does not continue the unfinished follow-up testing plan.
For CDL and CLP holders subject to FMCSA rules, the Clearinghouse records key milestones in that process. The driver remains in prohibited status until the required negative return-to-duty result is reported. Since November 18, 2024, prohibited status can also lead to removal of the driver's commercial driving privilege by the State Driver Licensing Agency. If that happens, changing to not prohibited does not by itself put the CDL back into driving status. The driver must also complete the state's reinstatement process.
A DOT-qualified SAP must meet the professional credential, training, examination and continuing education requirements in Part 40. SAP referral rules also restrict financial conflicts of interest. With limited regulatory exceptions, a SAP cannot direct a driver into the SAP's own private practice or to a treatment or education provider from which the SAP receives payment or has a financial interest.
Questions drivers ask.
Understand the process before choosing your next step.
Ready to find a SAP? Get quotesHow long does the return-to-duty process take?
There is no fixed completion time. Your SAP recommends education or treatment based on your assessment and evaluates your compliance. DOT advises SAPs against estimating a return-to-duty timeline before the initial evaluation. Read DOT’s guidance.
Can I have my SAP evaluation by video?
A SAP may conduct an evaluation remotely when DOT’s requirements are met. The decision is the SAP’s and the technology must support secure, real-time audio and video. Confirm suitability with your chosen provider. See the remote evaluation requirements.
What if I do not have a current employer?
FMCSA allows eligible drivers without a current or prospective employer to register as an owner-operator for the limited purpose of completing RTD testing and designate a C/TPA. That C/TPA can arrange the test and report the result. Follow FMCSA’s specific instructions; do not apply for a USDOT number for this option. Read the official guidance.
Does finishing the SAP process guarantee a job?
No. Meeting the required return-to-duty conditions does not require an employer to return you to a safety-sensitive position. The employer makes that employment decision. See DOT’s rule.
Does my violation disappear after the RTD test?
No. FMCSA retains violation information for five years from the violation determination, or until successful completion of the RTD process and follow-up testing plan, whichever is later. See Clearinghouse record guidance.
Is follow-up testing the same as random testing?
No. Your employer must implement the SAP’s follow-up testing plan. Tests conducted through a random testing program cannot replace the required follow-up tests. Read DOT’s testing requirements.
