FMCSA owner operator drug testing: are you covered?
Follow your truck through the CDL line. Tap any box for the rule behind it.
Is the truck or combination rated or loaded over 26,000 lb?RULE +
A CDL is needed for a single vehicle with a GVWR or GVW of 26,001 lb or more, or a combination of 26,001 lb or more when the trailer is rated over 10,000 lb. Rating or actual weight, whichever is greater.
49 CFR 383.5
Does it haul hazmat that needs placards?RULE +
Any vehicle hauling hazardous materials in a quantity that requires placards needs a CDL, whatever its weight.
49 CFR 383.5
Is it designed to carry 16 or more people, driver included?RULE +
Vehicles designed for 16 or more passengers, including the driver, need a CDL.
49 CFR 383.5
ANY ANSWER IS YES
CDL needed: DOT testing applies
You must follow Part 382: pre-employment, random and the other tests, Clearinghouse and records. As an owner operator you handle the employer side too.
ALL THREE ARE NO
No CDL: not covered by DOT testing
Part 382 does not apply. A shipper, broker or your own company policy can still ask for non-DOT testing.

DOCK 04SETUP
Owner operator drug testing program: the setup checklist
Owner operator drug testing requirements come down to six things, because you are the employer and the driver. One person carries both sets of duties. The usual way to handle the employer side is a consortium.
- 1.
Join a random testing pool
A pool of one cannot be random. A consortium places you in a pool with other drivers.
- 2.
Take a pre-employment drug test
With a verified negative result before your first load.
- 3.
Register in the Clearinghouse
Register as an employer and designate your consortium as your C/TPA, so it can handle reporting.
- 4.
Run the queries
A pre-employment full query on yourself and the annual query, through the Clearinghouse.
- 5.
Have a written policy
A drug and alcohol policy and the educational materials Part 382 requires. Consortiums usually provide templates.
- 6.
Keep the records
Results, selection history and enrollment, ready for a safety audit or investigation.
Skipping these is a violation of Part 382. It can lead to penalties and to problems at your new entrant safety audit, and brokers may ask to see your enrollment certificate before they load you.

Do truck drivers get drug tested? Drug testing for trucking companies
Every CDL truck driver working for a motor carrier is in a DOT testing program: a truck driver drug test before the first trip, random tests through the year, and the other tests when the rules call for them. Trucking companies with employed CDL drivers run the program as the employer, often through a consortium or third-party administrator.
A trucking drug test under DOT rules is a urine drug test and, for alcohol, a breath or saliva test, collected at certified sites under 49 CFR Part 40. Fleets also query each new CDL driver in the Clearinghouse before they drive and query current drivers at least once a year.
So do non CDL drivers get drug tested? Not by DOT. Only by company policy or a customer's requirement.
DOCK 05BOX TRUCKS
Do box truck drivers get drug tested?
Usually not under DOT rules. Most 26 ft box trucks are built at or under 26,000 lb GVWR, so they need no CDL, and DOT drug and alcohol testing applies only to CDL drivers. Check the weight rating on the driver's door sticker, not the box length.
That changes the moment the truck needs a CDL: a straight truck rated over 26,000 lb, a box truck pulling a heavy trailer, or any truck hauling placarded hazmat. Then the full program applies, including for an owner operator.
Non-CDL drivers can still be tested outside the DOT program. A shipper or broker can require it, and a company can set its own non-DOT policy. Those tests follow the company's rules, not Part 382.

DOCK 06FAQ
Drug testing questions
Q-01Do owner-operators need random drug testing?
Yes, if they drive a truck that needs a CDL. An owner operator is both employer and driver, so the random testing rules apply, and a one-person company has to be in a larger pool, usually through a consortium. Owner operators of non-CDL trucks are outside the DOT testing program.
Q-02Do box truck drivers get drug tested?
Under DOT rules, only if the box truck needs a CDL: over 26,000 lb GVWR or hauling placarded hazmat. Most 26 ft box trucks are rated at or under 26,000 lb, so their drivers are not in the DOT program. A shipper, broker or company policy can still require non-DOT tests.
Q-03Do non-CDL drivers get DOT drug tested?
No. DOT drug and alcohol testing under Part 382 covers drivers who need a CDL. Non-CDL drivers can still be tested by an employer or customer under a company policy, but those are non-DOT tests with their own rules.
Q-04What happens if an owner-operator is not in a random pool?
Driving a CDL truck without a testing program is a violation of Part 382. It can bring penalties and cause trouble in your new entrant safety audit or any later investigation. Brokers and shippers may also ask for proof of enrollment before they tender loads.
Q-05What drugs are on a DOT drug test?
Five classes: marijuana, cocaine, amphetamines (including methamphetamine and MDMA), opioids (including heroin, codeine, morphine, oxycodone and hydrocodone) and phencyclidine (PCP). The test is a urine test collected at a certified site and reviewed by a Medical Review Officer.
