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 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.

For drivers who completed the SAP process and need the required observed DOT RTD test before returning to safety-sensitive duties.

What Is the RTD Step 5 Drug Test?

The Return-to-Duty Step 5 drug test is a federally required DOT test that must be completed after a driver violates DOT drug or alcohol regulations - and before returning to any safety-sensitive duties.

This requirement is mandated under 49 CFR Part 40 and enforced through the FMCSA Drug & Alcohol Clearinghouse. A driver cannot legally operate a commercial motor vehicle until the RTD test result is verified negative and properly reported to the Clearinghouse. Passing the test alone is not enough - the Clearinghouse update must also be completed before the driver may return to duty.

The RTD Step 5 test is required after any of the following violations:

Positive drug test - any DOT-regulated substance confirmed by MRO

Refusal to test - including no-show, leaving the site, or refusing observed collection

Adulterated specimen - specimen tampered with to defeat the test

Substituted specimen - specimen not consistent with normal human urine

Important: SAP Steps 1-4 Are Separate

Before ordering Step 5, the driver must complete the SAP evaluation and any required education or treatment. goMDnow does not provide SAP assessments. Step 5 should be ordered only after the SAP has made the driver eligible for RTD testing.

If you have not completed SAP steps 1-4, contact your SAP first before scheduling the RTD drug test.

What the Price Includes

RTD Step 5 - total price $149.95 / driver

DOT Urine Drug test$69.95

Observed testing$45

FMCSA Clearinghouse reporting support$35.00

The observed collection is required by DOT for all RTD and follow-up tests - a same-gender collector must be present during the entire specimen collection.

SAP Assessment (Steps 1-4) is not included. goMDnow is not responsible for SAP assessments. The SAP process must be completed with an independent DOT-qualified Substance Abuse Professional before the RTD Step 5 test can be ordered.

Step 5 vs Step 6

Step 5 is the single return-to-duty test required before the driver can return to safety-sensitive work. Step 6 is follow-up testing that begins after the driver has returned to duty and follows the SAP-prescribed follow-up testing plan.

If you already passed your RTD test and now need follow-up testing, enroll in Step 6 follow-up testing instead.

Employer Responsibilities

Employers and owner-operators share responsibility for ensuring the RTD process is followed correctly. An employer who allows a driver with PROHIBITED status to operate a CMV faces serious FMCSA penalties - even if the driver initiated the RTD process.

Do not allow the driver to perform any safety-sensitive function until the negative RTD result is both received and reported to the Clearinghouse
Verify the driver's Clearinghouse status has changed from PROHIBITED before return to duty
Ensure the driver has a SAP-prescribed follow-up testing plan (Step 6) in place after returning to duty
Maintain records of the RTD test and Clearinghouse reporting for FMCSA audit readiness

goMDnow handles Clearinghouse reporting as part of the RTD package - removing this administrative burden from the employer.

Frequently Asked Questions

Can I order the Step 5 RTD test before completing the SAP process?

No. The SAP evaluation and any required education or treatment (Steps 1-4) must be completed before the RTD Step 5 test can be ordered. The SAP must confirm the driver is eligible before goMDnow can process the test.

Is the RTD test directly observed?

Yes. DOT requires the Step 5 RTD drug test to be directly observed - a same-gender collector must be present for the entire specimen collection, as required under 49 CFR Part 40.

Does goMDnow report the RTD result to the FMCSA Clearinghouse?

Yes. FMCSA Clearinghouse reporting is included in the RTD Step 5 price. A negative result is reported after MRO confirmation, which updates the driver's status from PROHIBITED in the Clearinghouse.

Can owner-operators order the RTD Step 5 test through goMDnow?

Yes. goMDnow supports both owner-operators and employer-sponsored CDL drivers. The RTD Step 5 test can be ordered online at any time with same-day availability at most collection sites nationwide.

What happens if the RTD test result is positive?

A positive RTD Step 5 result is another DOT violation. The driver must restart the SAP process from Step 1 - a new SAP evaluation is required before any subsequent RTD test can be ordered.

Does goMDnow assign or provide the SAP (Steps 1-4)?

No. goMDnow manages the testing portions of the RTD process - Step 5 and Step 6. The SAP evaluation and treatment (Steps 1-4) must be arranged independently with a DOT-qualified Substance Abuse Professional.

Can a driver return to work while waiting for the Clearinghouse to update?

No. The driver must not perform any safety-sensitive function until the negative RTD result is both confirmed by the MRO and reported to the Clearinghouse. The employer must verify the PROHIBITED status has been removed before the driver returns to duty.

How long does the RTD process take from start to finish?

Timeline varies based on SAP scheduling and treatment requirements. Once the SAP confirms eligibility, the Step 5 test can be ordered and completed same-day. Results are typically available within 24-48 hours after collection.
