What is the SAP Program?
The Substance Abuse Professional (SAP) Program, or the Return-to-Duty Process, is a federally mandated process under 49 CFR Part 40 by the Department of Transportation (DOT).
If you fail or refuse a DOT drug or alcohol test, you must:
Step 1
Complete an SAP evaluation with a DOT-qualified professional
Step 2
Follow the treatment or education plan recommended by the SAP
Step 3
Undergo a follow-up SAP evaluation to confirm compliance
Step 4
Pass a Return-to-Duty (RTD) drug test
Return-to-Duty (RTD) Drug Test
Your Final Step to Getting Back to Work
The Return-to-Duty (RTD) drug test is the LAST requirement for returning to work after a DOT violation.
Employer
If you're employed, your employer schedules the test.
No Employer:
We will connect you with a Consortium/Third-Party Administrator (C/TPA) to arrange the test.
Owner Operator
We will connect you with a Consortium/Third-Party Administrator (C/TPA) to arrange the test.
Complete Your SAP Program
Including your initial evaluation, treatment/education requirements, and follow-up evaluation.
Receive Your SAP's Report
Your SAP will confirm your eligibility for the RTD test and send this report to your employer or C/TPA.
Schedule & Take the RTD Test
The test must be conducted at a DOT-approved facility and must be directly observed to ensure compliance.
Pass the Test & Get Back to Work
A negative test result officially removes your prohibited status, allowing you to resume safety-sensitive duties.
We work with certified DOT-approved labs nationwide to ensure fast and accurate results, helping you complete your Return-to-Duty process as quickly as possible.
