When is a Return-to-Duty (RTD) test required?

An RTD process is required after a positive drug or alcohol test, a refusal to take a required test, or any DOT-defined drug and alcohol program violation under 49 CFR Part 40, Subpart O. A driver must complete the RTD process before returning to safety-sensitive duties.

What are the RTD step-by-step requirements?

Steps include immediate removal from safety-sensitive duties, SAP referral and evaluation (49 CFR § 40.293), completion of SAP-recommended treatment/education and SAP re-evaluation (49 CFR § 40.303), scheduling and performing an observed RTD test at a DOT-certified collection site and HHS-certified laboratory, MRO review, Clearinghouse reporting, and a follow-up testing plan (minimum six unannounced tests in year one, up to five years).

Can an owner-operator perform follow-up testing without an employer?

No — per DOT regulations the follow-up testing plan must be carried out under the direction of an employer. Owner-operators must hire a TPA (such as goMDnow) to act as their official representative to manage RTD and follow-up testing.

What happens if I fail the RTD test?

If a driver fails the RTD test they cannot return to safety-sensitive duties; they may need to repeat the SAP process and remain disqualified from performing safety-sensitive functions until requirements are met.

How long does the RTD process take?

The timeline varies depending on SAP recommendations and completion of treatment or education — it may take weeks or months based on the required program.

How many follow-up tests are required after RTD?

SAP typically prescribes a minimum of six unannounced, observed tests in the first 12 months after RTD. Follow-up testing may continue for up to five years as directed by the SAP.
