DOT Return-to-Duty Process

Failed a Workplace Drug Screen or Facing a DOT Violation?

As qualified Substance Abuse Professionals (SAP), we guide you through the federal return-to-duty process efficiently so you can get back to work legally and safely.

The DOT-SAP process is the federal “return-to-duty” program for drivers or safety-sensitive employees who failor refuse a DOT drug or alcohol test. “SAP” stands for Substance Abuse Professional.

It applies to workers regulated by six agencies:

  1. FMCSA — Federal Motor Carrier Safety Administration: Truck drivers, CDL holders, motor carriers
  2. FAA — Federal Aviation Administration: Pilots, flight crews, aircraft mechanics, air traffic roles
  3. FRA — Federal Railroad Administration: Railroad employees
  4. FTA — Federal Transit Administration: Public transit workers (bus, subway, rail)
  5. PHMSA — Pipeline and Hazardous Materials Safety Administration: Pipeline and hazardous material
  6. workers
  7. 6USCG — U.S. Coast Guard: Mariners and commercial vessel crews

When the SAP process is required

You must enter the SAP process if you:

  • Fail a DOT drug test
  • Fail a DOT alcohol test
  • Refuse a DOT test
  • Violate DOT drug/alcohol rules

Once that happens, you are immediately removed from safety-sensitive duties (like driving a commercial vehicle).

What to Expect

The 5 main steps in the DOT-SAP process

Step 1

Initial SAP Evaluation

You meet with a qualified SAP, who evaluates your situation and determines what education, counseling, ortreatment is needed.

This may be:

• Drug/alcohol education classes

• Counseling

• Outpatient treatment

• Inpatient rehab (in severe cases)

Step 2

Complete Treatment or Education

You must fully complete whatever the SAP recommends.There’s no set timeline—it may take days, weeks, or months depending on the recommendation.

Step 3

Follow-Up SAP Evaluation

After treatment, the SAP meets with you again to confirm you complied with all requirements.If satisfied, the SAP clears you for the next step.

Step 4

Return-to-Duty Test

You take a DOT return-to-duty drug/alcohol test.

• Drug tests are directly observed

• You must test negative

• For alcohol, the result must be below 0.02

You can only return to safety-sensitive work after passing.

Step 5

Follow-Up Testing Program

After returning to work, you are placed into a follow-up testing program.

Typically:

• At least 6 unannounced tests in the first 12 months

• Testing can continue for up to 5 years

• This is in addition to normal random testing.

The SAP determines the schedule.

FMCSA Clearinghouse Involvement

For CDL drivers, the violations and SAP progress are tracked in the FMCSA Drug & Alcohol Clearinghouse.The SAP must approve your request in the Clearinghouse before you can enter your return-to-dutyinformation.

How long does it usually take?

It depends mainly on:

• SAP recommendations

• How quickly treatment is completed

• Employer requirements

How long does it usually take?

Completing the SAP process does not guarantee that your old employer will rehire you.

• A company must employ you.

It only restores your eligibility for DOT-regulated safety-sensitive work.

Frequently Asked Questions (FAQs)

Department of Transportation (DOT) & Substance AbuseProfessional (SAP) FAQS

What is the Federal Motor Carrier Safety Administration (FMCSA) Clearinghouse?

(FMCSA regulated drivers only) The Clearinghouse is a national database that logs violations since 2020.Records remain at least five years or until SAP follow-up is complete. Employers must check records andcannot hire until SAP compliance is confirmed.

Who pays for SAP services?

DOT doesn’t specify who pays. Some employers cover the cost or use Employee Assistance Programs (EAPs),but many require employees to pay. Check your employer’s policy or ask if unsure.

How much do the SAP services at 616 SUDS cost?

The SAP service fee is $700. This covers only the SAP evaluations and does not include any additionaltreatment costs that may be required.

What if I can’t afford the SAP’s recommended plan?

What if I test positive on a follow-up test?
