The DOT drug and alcohol program for a small carrier: what you actually need
Why a one-truck carrier still needs all of it
Part 382 does not have a small-employer exemption. The rules attach to the driver holding a CDL, not to the size of the company. An owner-operator is the employer of one driver, themselves, and owes every duty on the list. The only relief the rule gives is that an owner-operator with no other drivers does not need supervisor training, because there is nobody to supervise.
The consortium, and why it is not optional for the small carrier
Random testing must be unannounced and statistically random. A pool of one cannot be randomly sampled, so 382.305 effectively requires small carriers to join a consortium or use a third-party administrator that pools drivers across companies. There are no DOT qualification requirements to be a C/TPA, so choose one that can show you it knows Part 40. The employer remains responsible for the C/TPA's errors.
The 2026 random rates
DOT confirmed on January 8, 2026 that the minimum annual random testing rates remain 50 percent for controlled substances and 10 percent for alcohol, the sixth consecutive year at those levels. The drug rate drops to 25 percent only if the industry positive rate stays below one percent for two consecutive years. Your consortium runs the selections; you make sure every selected driver tests.
Pre-employment, post-accident, reasonable suspicion
Pre-employment: a negative drug test result before the driver performs any safety-sensitive function (alcohol is optional). Post-accident: after a fatality, or after an injury or tow-away crash where the driver receives a citation. Reasonable suspicion: when a trained supervisor observes specific indicators; the observer must have completed 382.603 training, which is the piece most small carriers are missing.
The Designated Employer Representative
Every program needs a DER: the person who receives test results and can immediately remove a driver from safety-sensitive duty. It must be an employee with that authority, not an outside vendor, though a C/TPA can do the administrative work. In a small carrier the DER is usually the owner.
What an auditor will want to see
The written policy with each driver's signed receipt, the consortium agreement and random selection records, pre-employment results, Clearinghouse query records, supervisor training certificates, and, if any test was positive, the return-to-duty file. Missing any of the first three is on the new-entrant audit's automatic-failure list.
Questions drivers ask
Can I run my own random program with three drivers?
Technically yes, but a pool of three is hard to defend as random and the administration is more than the consortium fee. Most small carriers join a consortium.
Does the owner-operator need supervisor training?
Only if they supervise another CDL driver. An owner-operator with no other drivers is exempt from 382.603; the moment they hire a driver, they need it.
What does supervisor training cost and how long does it take?
ELDT365 offers the 382.603 course online at $29. It is two hours, one-time, with a certificate for the file.
Is CBD or legal marijuana a problem for my drivers?
Yes. DOT tests for THC and does not accept state legalization or CBD use as an explanation for a positive. Tell your drivers plainly.
