SAP’s Do’s and Don’ts

The Do’s and Don’ts for Substance Abuse Professionals and the Return-to-Duty Process in the DOT Drug and Alcohol Testing Program

What You Need to Know:

On March 4, 2026, the U.S. Department of Transportation (DOT) released an important notification for Substance Abuse Professionals (SAPs) and DOT-regulated employers. This blog post will break down key points from this notification to ensure both SAPs and employers effectively support safety-sensitive employees returning to duty after a DOT drug or alcohol violation.

Why Is This Notification Important?

The Substance Abuse Professional (SAP) is the “gatekeeper” of the Return-to-Duty (RTD) process, holding enormous responsibility for public safety. SAPs make pivotal decisions about when an employee who violated drug or alcohol rules can resume safety-sensitive duties, such as driving a bus, flying a plane, or operating heavy machinery.

In recent years, DOT has noticed concerning trends and compliance gaps in the RTD process. This notification serves as a comprehensive reminder: SAPs and employers must follow all federal procedures outlined in 49 CFR Part 40.

The Do’s: SAP Responsibilities in the RTD Process

1. Protect the Public Interest
   • Your primary responsibility is to objectively evaluate employees and recommend education, treatment, and follow-up testing to safeguard public safety.
2. Adhere to DOT and State Credentials
   • SAPs must hold DOT-approved qualifications and credentials and be up to date (including 12 hours of relevant professional development every three years).
3. Conduct Individualized Evaluations
   • Each assessment must be unique and comprehensive, including psychosocial history, substance use history, and current mental status. No two employees are the same; your recommendations must reflect their individual needs.
4. Provide Clear and Complete Reports
   • Supply all required reports directly to employers and, with redactions, to employees. Maintain records for five years in secure, limited-access areas.
5. Ensure Evaluations Are Face-to-Face
   • Evaluations must occur via live, two-way audio and visual communication (in-person or remote).
6. Follow Federal and Mode-Specific Rules
   • Be aware of unique requirements from FAA, FMCSA, FRA, etc., especially regarding follow-up testing and documentation.

The Don’ts: Critical Compliance Pitfalls to Avoid

1. Don’t Be an Advocate
   • SAPs are not advocates for either the employer or employee.
2. Don’t Promise RTD Timelines in Advance
   • Never predict how long the RTD process will take before a full, individualized initial evaluation.
3. Don’t Cut Corners Due to Employer or C/TPA Pressure
   • Avoid setting the minimum follow-up testing based on external pressure. Recommendations must be clinically justified.
4. Don’t Provide Employees a Copy of Their Follow-up Testing Plan
   • This information is for employers only, per federal rules. Employees should only see redacted reports that exclude the follow-up plan.
5. Don’t Reuse or Template Recommendations
   • Assigning the same education or treatment plan to every employee is a violation of federal protocols.
6. Don’t Fast-Track Evaluations
   • Rapid, “cookie-cutter” assessments designed to get employees back to work faster undermine the integrity of the RTD process.
7. Don’t Operate Outside Credential Jurisdiction
   • Only conduct evaluations within the geographical scope allowed by your credentials.
8. Don’t Perform Unqualified Services
   • Only SAPs who meet all credential, training, and exam requirements may conduct DOT SAP services.

Key Takeaways for Employers

• Ensure SAPs are DOT-qualified and follow the protocol in 49 CFR Part 40.
• Do not share the follow-up testing plan with the employee.
• If in doubt, consult the latest DOT SAP Guidelines (PDF) or contact DOT for clarification.

Why Compliance Matters

Noncompliance can lead to:

• Public Interest Exclusion proceedings
• Invalidation of SAP determinations
• Safety failures and reputational harm

SAPs and employers should always use federal documentation as the authoritative source. Review the full 49 CFR Part 40 text or contact the Office of Drug and Alcohol Policy and Compliance for guidance.

Bottom line: The RTD process is about much more than compliance—it’s about safety, integrity, and individualized support for affected employees. For more details, visit the DOT’s official drug and alcohol policy page.
