Step-by-Step Compliance
The DOT Return to Duty process is strictly defined under 49 CFR Part 40. Every step must be completed in sequence before a driver can return to safety-sensitive functions.
Removal from Safety-Sensitive Duties
Immediately upon a verified positive or refusal, the employee must be removed from all safety-sensitive functions.
SAP Evaluation
A qualified Substance Abuse Professional (SAP) evaluates the employee and recommends education or treatment.
Education / Treatment
The employee completes the SAP's prescribed education or treatment program.
SAP Follow-Up Evaluation
The SAP re-evaluates the employee to determine if treatment was completed successfully.
Return-to-Duty Drug Test — $159.95
The employee must pass a directly observed urine drug test with a negative result. Our fee of $159.95 includes the observed collection, MRO review, and mandatory reporting to the FMCSA Drug & Alcohol Clearinghouse.
Follow-Up Testing Program — Enroll in Doctors Place TPA
The SAP prescribes a random follow-up testing schedule (minimum 6 unannounced tests in the first 12 months). To be placed in the Doctors Place follow-up testing program, the driver or employer must select Doctors Place TPA Services inside their account — available for employers, owner-operators, and student/CDL drivers.
⚠️ Important: A driver cannot return to safety-sensitive functions until ALL steps are completed and a negative RTD test is on file. Skipping any step violates 49 CFR Part 40.
SAP evaluation fee billed separately by the SAP provider.

RTD Questions
How long does the Return to Duty process take?
It depends on the SAP's recommendations. Some employees complete the process in 30 days; others may require longer treatment programs. There is no shortcut — every step must be completed.
Who pays for the SAP evaluation and treatment?
Under DOT regulations, the cost of the RTD process (including SAP evaluation and treatment) is typically the employee's responsibility, unless the employer chooses to cover it.
How many follow-up tests are required?
A minimum of 6 unannounced follow-up tests within the first 12 months of return to duty. The SAP may require more, and testing can extend up to 5 years.
Does the driver need a new DOT physical after RTD?
Not necessarily, unless their medical certificate has expired. However, some employers require a new physical as part of their return-to-work policy.
How do I enroll in follow-up testing for Step 6?
You must select Doctors Place TPA Services inside your account on our portal. We support three account types: Employer accounts (for companies managing drivers), Owner Operator accounts (for independent CDL drivers), and Student/CDL Driver accounts. Once enrolled, we manage your random follow-up schedule automatically per the SAP's plan.
What does the $159.95 Step 5 fee include?
Everything required for the return-to-duty drug test: the directly observed urine collection at one of our nationwide collection sites, MRO (Medical Review Officer) result review, and mandatory reporting of the negative result to the FMCSA Drug & Alcohol Clearinghouse. No hidden add-ons.
Can owner-operators manage their own RTD process?
Yes. Owner-operators can create an account at our portal and select Doctors Place TPA Services to handle their Step 5 test and Step 6 follow-up testing — without needing an employer to act on their behalf.
