DOT Clearinghouse SAP: How the Return-to-Duty Process Works
DOT Clearinghouse SAP: How the Return-to-Duty Process Works

If you hold a CDL and have a drug or alcohol violation in the FMCSA Clearinghouse, a Substance Abuse Professional (SAP) is the person who opens the way back to safety-sensitive work. You choose a SAP, designate that SAP in the Clearinghouse, complete the evaluation and whatever education or treatment is recommended, and the SAP reports two dates. Your employer, or a third-party administrator acting for you, then handles the return-to-duty test that clears your status. This guide walks through each step, what the SAP can and cannot do in the Clearinghouse, and what to expect afterward.
TL;DR
- A violation puts you in “prohibited” status, and you cannot perform safety-sensitive functions until the return-to-duty (RTD) process is complete.
- You must be registered in the Clearinghouse, contact the SAP first, and then designate that SAP. Once the SAP accepts, you cannot switch to a different one in the system.
- The SAP enters only two items: the date of your initial assessment and the date you become eligible for RTD testing. The employer or a C/TPA enters the negative RTD test result.
- Follow-up testing includes at least six unannounced tests in the first 12 months back on safety-sensitive duty.
- We provide SAP evaluations by live Zoom, so you can start without a car or a day off. A SAP evaluation with us is $400.

What a SAP does in the Clearinghouse process
A SAP evaluates employees who have violated a DOT drug and alcohol program regulation and recommends education, treatment, follow-up testing and aftercare. The DOT describes the role as a major decision point for an employer deciding whether someone returns to safety-sensitive work, and that weight is why the rules are specific about who may serve.
The DOT does not certify, license or approve individual SAPs. Under FMCSA guidance, a SAP must be a licensed physician, a licensed or certified psychologist, social worker or employee assistance professional, or a certified addiction counselor, with clinical experience in substance abuse disorders. Inside the Clearinghouse, SAPs register, verify their identity, and self-certify that they meet the qualifications in 49 CFR 40.281.
For a fuller explanation of the role outside the Clearinghouse, see our guide on what SAP evaluations are.
The return-to-duty process, step by step
FMCSA’s own RTD process overview lays out seven steps. Here they are in plain order, with who acts at each one.
| Step | What happens | Who acts |
|---|---|---|
| 1 | Employer provides a list of DOT-qualified SAPs, and you choose one | Employer and driver |
| 2 | You designate the SAP in the Clearinghouse | Driver |
| 3 | The SAP performs the initial evaluation | SAP |
| 4 | The SAP gives the employer education or treatment recommendations | SAP |
| 5 | After you finish the plan, the SAP re-evaluates and sets a follow-up testing plan | SAP |
| 6 | The employer sends you for an RTD test | Employer or C/TPA |
| 7 | Any employer during the prescribed period completes the follow-up testing plan | Employer |
You are no longer prohibited from safety-sensitive functions once you have a negative RTD test result.
Step 1: Choose a SAP
The employer is expected to give you a list of DOT-qualified SAPs. You pick one. Choose someone who answers the phone, can see you quickly and explains each stage, because every later step depends on this relationship. We have written a separate walkthrough of every step back to work if you want the longer version.
Step 2: Register and designate your SAP
You need a Login.gov account to register. Drivers enter and verify their CDL or CLP information and accept the terms, and registering is what lets you view your own record and respond to employer consent requests.
Before you designate anyone, contact the SAP and establish a relationship. Once the SAP accepts your request, you cannot designate a different SAP in the Clearinghouse. If something unforeseen prevents your SAP from overseeing your plan, FMCSA says to contact the agency for help. Because the choice is effectively final, confirm the SAP’s availability and your timeline before you click.
Step 3: The initial evaluation
The SAP meets with you, reviews your violation and history, and decides what education or treatment fits. At our practice this happens live over Zoom, and same-day and expedited appointments are available when a deadline is close. Our virtual SAP evaluation page explains how a remote session works.
After the evaluation, the SAP enters the date of the initial assessment in the Clearinghouse. Nothing else from the evaluation goes into the system.
Steps 4 and 5: The plan, then re-evaluation
The SAP gives your employer the education or treatment recommendation. That might be an education course, counseling or a higher level of treatment, and it is based on your evaluation, not on a standard formula. You complete the plan, then return for a follow-up evaluation. When the SAP determines you completed it, the SAP enters the date you become eligible for RTD testing and writes the follow-up testing plan.
Steps 6 and 7: RTD test and follow-up testing
The SAP does not order the RTD test and does not report it. SAPs may not order the RTD test or report it to the Clearinghouse. Your employer sends you for it. Before returning to duty, you must pass an RTD test with an alcohol concentration below 0.02 and/or a verified negative controlled-substances result, and have a documented follow-up testing schedule.

If you have no current or prospective employer to send you, the driver may register as an owner-operator and designate a C/TPA for the limited purpose of completing RTD. When the C/TPA reports the negative result, your status changes from prohibited to not prohibited.
Who reports what in the Clearinghouse
Much of the confusion about “Clearinghouse SAP status” comes from not knowing who enters which information. Per the FMCSA FAQ on violations and RTD:
- Employers or C/TPAs enter drug and alcohol program violation information, and MROs enter drug violation information.
- SAPs enter the date of the initial assessment and the date the driver is eligible for RTD testing.
- Employers enter the negative RTD test results and the date the follow-up testing plan was successfully completed.
SAPs do not upload the treatment plan, reports or other information, and cannot access a driver’s violation information. That is why your SAP will ask you to share your paperwork directly with your employer.
What the status labels mean
In FMCSA’s state licensing agency handbook, the driver status values include PROHIBITED (a violation is recorded and RTD is not complete), NOTPROHIBITED (no violations recorded), and REPROHIBITED (a new violation after a prior RTD). Others, such as RTDCOMPLETE7DAY, RTDCOMPLETE30DAY and RTDCOMPLETE90DAY, relate to completed RTD records. For your own situation, the one that matters is simple: prohibited means you cannot drive CMVs, and not prohibited means the process is complete.
Can you drive while in the SAP program?
No, not in a safety-sensitive role. A driver with a verified violation is prohibited from safety-sensitive functions until the RTD process is complete, and that process is governed by 49 CFR part 40, subpart O.
There is also a licensing consequence. Beginning November 18, 2024, state driver licensing agencies must query the Clearinghouse before issuing, renewing, transferring or upgrading a CDL or CLP, and a driver with a prohibited status loses or is denied commercial driving privileges, which means a downgrade until RTD is complete. Finishing the process quickly matters for your license as well as your job.
How long a violation stays on your record
The information is retained for five years from the violation determination or until you complete the follow-up testing plan, whichever is later. Finishing RTD changes your status to not prohibited, but the record itself remains for that period, and employers who query with your consent can see it.
To stay in good standing, your employer must complete the follow-up testing plan the SAP specifies. It must include at least six unannounced follow-up tests in the first 12 months after you return to safety-sensitive functions. The SAP can require more tests, and can extend testing beyond 12 months.
When you change employers, a negative RTD test can sometimes double as a pre-employment test. The FMCSA overview says this applies when a new employer would otherwise have to conduct both tests on the same day under 49 CFR 382.309.

What a SAP evaluation costs
The evaluation fee and the cost of any recommended education or treatment are separate. Our SAP evaluation is $400, as published on our pricing page. The education or treatment your SAP recommends, and the RTD and follow-up tests your employer or C/TPA arranges, are priced by whoever provides them, so ask for each cost before you commit to a step. Ask your SAP what the recommendation is likely to involve once the evaluation is complete, so you can plan.
Our view: speed and clarity are the whole job
When a driver calls us after a failed or refused test, the first thing we hear is worry about income. The process itself is fixed by federal rules, so what we control is how quickly and clearly you move through it. That is why we built a full team that answers the phone, rather than a one-person practice that goes to voicemail.
We offer live Zoom SAP evaluations, because a driver who is off the road often has no way to get to an office and cannot afford to wait weeks for an opening. Same-day and expedited appointments are available when a deadline is close. We explain, before the first session, what we will report, what your employer will receive and what happens next, so that nothing in the Clearinghouse surprises you.
Our goal is to help you finish each step correctly the first time, with paperwork your employer can use, and without judgment.

A practical checklist before you call a SAP
- Register in the Clearinghouse with Login.gov and verify your CDL or CLP information.
- Ask your employer for the list of DOT-qualified SAPs, or find one if you have no employer.
- Call the SAP and talk before you send a designation request, and confirm the appointment date.
- Designate the SAP only when you are sure, since it cannot be changed after acceptance.
- Keep copies of your recommendation, class certificates and any treatment attendance records.
- Ask your employer or C/TPA to schedule the RTD test once the SAP reports you eligible.
- Keep your contact information current in the Clearinghouse so notices reach you.
Our SAP evaluation process guide covers the steps, requirements and timeline in more detail.

FAQ
Do I have to register in the Clearinghouse before seeing a SAP?
Yes, to designate a SAP you must be registered. FMCSA notes that drivers are not required to register generally, but must register to view their record and respond to employer consent requests. Registering takes a Login.gov account and your CDL or CLP details, so do it before your appointment.
Can the SAP see my violation in the Clearinghouse?
No. SAPs cannot access a driver’s violation information in the Clearinghouse. They enter the dates of your initial assessment and RTD eligibility only, so bring the details of your violation to the evaluation.
Does the SAP clear my status?
Not by itself. The SAP reports that you are eligible for RTD testing, but your status changes after you have a negative RTD test result entered by your employer or C/TPA. Plan for that test as the final step.
What if I have no employer?
You can register as an owner-operator and designate a C/TPA solely to complete RTD. The FMCSA FAQ says the C/TPA reports the negative RTD result, and your status then moves from prohibited to not prohibited.
