What Is the DISA Return-to-Duty Process?
The DISA Return-to-Duty process is a formal procedure required for employees—particularly CDL drivers and safety-sensitive workers—who tested positive for drugs or alcohol. This process, guided by DOT regulations and DISA Global Solutions, ensures the employee is fit to return to safety-sensitive duties. It involves a SAP (Substance Abuse Professional) evaluation, treatment or education, and follow-up testing.
Whether you’re employed under the DOT, FMCSA, or working in a safety-sensitive role, this process is mandatory after a drug or alcohol policy violation.
Step-by-Step: How to Complete the DISA Return-to-Duty Process in 2025
Here’s what the full process looks like in 2025:
1. Immediate Removal from Duty
As soon as you test positive or refuse a drug/alcohol test, you’re removed from safety-sensitive functions. This includes driving a commercial vehicle, operating heavy machinery, or any role that can impact public safety.
2. Contact a Qualified SAP
You must find a DOT-qualified Substance Abuse Professional (SAP). DISA or your employer may provide a list, or you can choose a SAP independently.
💡 Tip: Choose a SAP who offers telehealth evaluations to complete this step faster and more conveniently.
3. Complete the SAP Evaluation
Your selected SAP will conduct a face-to-face or virtual clinical evaluation. Based on your assessment, they’ll recommend:
- Substance abuse treatment (if necessary)
- Education programs
- Counseling sessions
These recommendations are documented in a SAP report, which is sent to DISA and your employer.
4. Fulfill SAP Recommendations
You must complete all the treatment or education as recommended. Your SAP will track your progress, and you must provide documentation of your participation and completion.
5. SAP Follow-Up Evaluation
Once your program is complete, the SAP will conduct a final evaluation to determine if you are fit to return to duty. If successful, the SAP issues a Return-to-Duty Report.
6. Return-to-Duty Drug Test
You will then take a Return-to-Duty drug and/or alcohol test, which must be conducted under direct observation. You must test negative to be eligible to return.
⚠️ NOTE: This test is reported to DISA’s database and the FMCSA Drug & Alcohol Clearinghouse (if applicable).
7. Follow-Up Testing Plan
Your SAP will design a follow-up testing schedule for up to 5 years, with a minimum of 6 unannounced tests in the first 12 months.
What Are the Drug Testing Rules in 2025?
DISA drug testing follows DOT 49 CFR Part 40 and company-specific policies. Common rules include:
-
Return-to-Duty tests must be directly observed
-
Testing for:
- Marijuana (THC)
- Cocaine
- Opiates
- Amphetamines
- Phencyclidine (PCP)
- Alcohol
-
Random drug testing continues after reinstatement
DISA vs DOT: What’s the Difference?
| Feature | DOT Return-to-Duty | DISA Return-to-Duty |
|---|---|---|
| Required By | Federal regulations | Employers using DISA |
| Applies To | CDL drivers, safety-sensitive workers | Broader industries (energy, petrochem, logistics) |
| Reported To | FMCSA Clearinghouse | DISA database |
| SAP Role | Mandated | Mandated |
Failing to complete the process means you remain ineligible for employment in any safety-sensitive role. Employers regularly consult DISA’s internal compliance systems, and incomplete records can block you from hiring opportunities.
Final Takeaways: Key Tips to Complete the Process Successfully
- ✔️ Start your SAP evaluation immediately after violation
- ✔️ Choose SAPs who understand DISA and DOT compliance
- ✔️ Stay consistent and communicative during treatment
