DOT Return-to-Duty Process for CDL Drivers & DOT-Regulated Employees 

What Is the DOT Return-to-Duty Process? 

The DOT Return-to-Duty (RTD) process is the federally required process that a DOT-regulated employee must complete after certain drug or alcohol testing violations before becoming eligible to return to safety-sensitive duties.

A DOT drug or alcohol violation can immediately remove an employee from safety-sensitive work. Completing another drug test by itself is not enough to return to duty. The employee must first complete the required process with a DOT Qualified Substance Abuse Professional (SAP).

What Are the Steps in the Return-to-Duty Process? 

The Return-to-Duty process generally involves the following steps:

1. Select a DOT Qualified SAP.
   The employee must work with a qualified Substance Abuse Professional.

2. Complete the initial SAP evaluation.
   The SAP evaluates the employee and determines the appropriate education and/or treatment recommendation.

3. Complete the SAP recommendation.
   The employee completes the education and/or treatment prescribed by the SAP.

4. Complete the follow-up SAP evaluation.
   The SAP determines whether the employee has successfully complied with the recommendation and whether the employee is eligible to proceed in the Return-to-Duty process.

5. Complete the Return-to-Duty test.
   The applicable employer or authorized party arranges the required Return-to-Duty drug and/or alcohol test. The required result must be obtained before the employee may resume safety-sensitive duties.

6. Complete follow-up testing.
   After returning to safety-sensitive work, the employee is subject to the SAP's follow-up testing plan in addition to any other DOT-required testing.

What Happens After a Failed DOT Drug Test? 

A failed DOT drug test does not permanently prevent an employee from returning to DOT-regulated work. However, the employee must be immediately removed from safety-sensitive functions and complete the required Return-to-Duty process before becoming eligible to perform those duties again.

The first step is to work with a DOT Qualified Substance Abuse Professional (SAP). The SAP conducts an initial evaluation and determines what education and/or treatment must be completed.

After successful compliance with the SAP's recommendation, a follow-up evaluation is conducted. If the SAP determines that the employee has successfully complied, the employee may proceed to the required Return-to-Duty testing process.

What Happens After Refusing a DOT Drug or Alcohol Test? 

Certain refusals to submit to DOT-required drug or alcohol testing are treated as DOT violations and require completion of the Return-to-Duty process.

If a refusal has been reported as a DOT violation, the employee must complete the SAP process before becoming eligible to return to safety-sensitive duties. The process includes an initial SAP evaluation, completion of the SAP's education and/or treatment recommendation, and a follow-up SAP evaluation before proceeding to Return-to-Duty testing.

For CDL drivers subject to FMCSA requirements, applicable violation and Return-to-Duty information is reported through the FMCSA Drug & Alcohol Clearinghouse.

How Long Does the DOT Return-to-Duty Process Take?

There is no standard number of days required to complete the DOT Return-to-Duty process. The timeline depends on the SAP's professional recommendation and how quickly the employee completes the required education and/or treatment.

The SAP cannot skip required steps or guarantee that the process will be completed within a specific number of days. Completing appointments and recommendations promptly can help prevent unnecessary delays.

After successful completion of the SAP recommendation and follow-up evaluation, the employee must still complete the required Return-to-Duty testing requirements before resuming safety-sensitive duties.

Can I Start the Return-to-Duty Process Without an Employer?

Yes. An employee can begin working with a DOT Qualified SAP and complete the SAP evaluation and recommended education and/or treatment even if they are not currently employed.

However, completing the SAP portion does not by itself authorize the employee to resume safety-sensitive work. The remaining Return-to-Duty requirements, including the required Return-to-Duty test, must be completed in accordance with the applicable DOT regulations.

For CDL drivers, the FMCSA Clearinghouse also tracks required Return-to-Duty information.

What Is DOT Follow-Up Testing? 

After an employee successfully completes the SAP process and returns to safety-sensitive duties, the employee is subject to a follow-up testing plan established by the SAP.

DOT regulations require a minimum of six unannounced follow-up tests during the first 12 months after the employee returns to safety-sensitive duties. The SAP may require additional testing, and the follow-up testing plan can continue for up to five years.

Follow-up testing is separate from other DOT testing requirements, such as random, post-accident, reasonable suspicion, or other required testing.
