Random Drug Testing | DOT & Non-DOT

Q: What happens if a driver refuses or misses a random test?

A refusal, including failing to report without a valid documented reason, is treated the same as a positive result under 49 CFR 40.191. The driver is removed from safety-sensitive functions, reported to the FMCSA Clearinghouse as PROHIBITED, and must complete the Return-to-Duty process.

Stay Compliant with Unannounced Random Testing

Random drug and alcohol testing is the backbone of a DOT-compliant program — and the area where employers most often fall out of compliance. Selections must be unannounced, spread reasonably throughout the year, and generated by a scientifically valid method.

goMDnow operates a certified C/TPA random testing consortium: we run the random draws, notify you the moment a driver is selected, direct the driver to a nearby collection site, and keep the documentation FMCSA expects to see during an audit or new-entrant safety review.

When is random testing required?

DOT-regulated employers with CDL drivers operating under FMCSA authority
Owner-operators — who cannot self-administer random testing and must join a consortium under 49 CFR Part 40
Employers subject to other DOT agencies (FTA, FAA, PHMSA, FRA, USCG) with random testing obligations
Non-DOT employers whose written drug-free workplace policy includes random testing
Client contracts or insurance requirements that mandate an active random program

DOT and Non-DOT Random Testing

goMDnow supports both DOT and non-DOT random testing. DOT random testing follows federal rules under 49 CFR Part 40 and Part 382 — annual minimum testing rates set by FMCSA, computer-based random selection, and immediate reporting obligations for violations. Every CDL driver must be enrolled in a compliant random pool; for owner-operators, that means a consortium.

Non-DOT random programs follow the employer's written drug-free workplace policy and applicable state law, so mixed fleets can manage regulated drivers and non-regulated employees through one provider.

How the process works

Enroll in the goMDnow random testing consortium.
Drivers are entered into the random pool after a negative pre-employment test.
Computer-based random selections run throughout the year at FMCSA-required rates.
You and the selected driver are notified immediately by email and text.
The driver completes testing at a nearby clinic, and results are delivered securely.

Why employers choose goMDnow

One provider runs the draws, handles the notifications, and keeps the records — so a random selection never depends on someone in your office remembering to act. When a driver is selected, they must proceed to the collection site promptly; under goMDnow's random testing policy, testing is completed no later than the next business day.

For Employers

Order tests, send employees or candidates to a nearby collection site, and receive secure results for your workplace program.

For Individuals

Complete required testing for employment, legal, agency, or compliance needs with clear instructions and support.

Key Requirements & What Employers Need to Know

Random testing is the most heavily audited element of a DOT drug and alcohol program. Selections must be unannounced, scientifically valid, and completed on time — for DOT-regulated fleets, additional requirements apply.

Annual testing rates (FMCSA) FMCSA requires random testing at a minimum annual rate of 50% of average driver positions for controlled substances and 10% for alcohol. A compliant consortium spreads selections reasonably across the calendar year.

Scientifically valid selection Selections must come from a scientifically valid method such as a computer-based random number generator. Every driver must have an equal chance in every draw — hand-picking or rotating drivers is a violation.

Unannounced means unannounced Drivers cannot be told in advance. Once notified, the driver must proceed to the collection site; under goMDnow's policy, testing is completed no later than the next business day, with short extensions only for documented safety or operational reasons.

Refusal = positive Failing to report, leaving the site, or otherwise refusing a random test is treated as a violation under 49 CFR 40.191 — the driver is PROHIBITED in the Clearinghouse and must complete the Return-to-Duty process before returning to safety-sensitive work.

Owner-operators cannot self-test: Under 49 CFR Part 40, owner-operators must join a consortium — you cannot manage your own random selections. Enrollment in the goMDnow consortium is $99.00/year, includes unlimited drivers with no add fees, and your enrollment certificate is emailed immediately after signup.

goMDnow manages DOT random pools and non-DOT random programs nationwide. Member pricing starts at $79.95 for urine testing. See full pricing →

Frequently Asked Questions

What is a random drug test?

A random drug test is an unannounced test where employees are selected by a scientifically valid, computer-based random method. For DOT-regulated drivers, random testing is required under 49 CFR Part 382 and must be managed through a compliant random pool or consortium.

How are drivers selected for random testing?

goMDnow uses a computer-based random number generator that gives every enrolled driver an equal chance of selection in every draw. Selections run throughout the year, and both the employer and driver are notified immediately by email and text.

What are the current FMCSA random testing rates?

FMCSA's minimum annual random testing rates are 50% of average driver positions for controlled substances and 10% for alcohol. The consortium manages these rates automatically across the pool.

How long does a driver have to complete a random test after notification?

The driver must proceed to a collection site promptly once notified — under goMDnow's random testing policy, no later than the next business day. Delays for convenience are not permitted, and short extensions require documented safety or operational reasons.

What happens if a driver refuses or misses a random test?

A refusal — including failing to report without a valid documented reason — is treated the same as a positive result under 49 CFR 40.191. The driver is removed from safety-sensitive functions, reported to the FMCSA Clearinghouse as PROHIBITED, and must complete the Return-to-Duty process.

Do owner-operators need random testing?

Yes. Owner-operators cannot administer their own random program under 49 CFR Part 40 — they must enroll in a consortium like goMDnow, which manages random selection, notifications, and Clearinghouse reporting.

Does the $99.00 consortium membership include the cost of each random test?

No. Membership covers random pool management, selections, notifications, MIS reporting, and audit support. Each test ordered is billed separately at member rates — urine testing from $79.95.

Can goMDnow run random testing for non-DOT employees?

Yes. Non-DOT random programs follow your written workplace policy and applicable state law. goMDnow supports both DOT and non-DOT random testing, so mixed workforces can be managed through one provider.
