DOT Random Drug & Alcohol Testing
FMCSA requires random drug and alcohol testing every year — 50% of drivers for drugs, 10% for alcohol, by a scientifically valid draw. We run the whole program: a compliant consortium pool, selections every period, and on-site collection across Nebraska and Kansas.
DOT random testing requires carriers to randomly test a minimum of 50% of drivers for drugs and 10% for alcohol each year (49 CFR 382.305). We run the whole program — compliant pool, valid selections, and on-site collection.
Random testing is the backbone of DOT drug and alcohol compliance — and the piece most likely to trip up a small carrier. The rates are non-negotiable, the selection has to be genuinely random, and a driver who isn't tested when selected is a violation waiting to be found.
The rates, met correctly
FMCSA requires annual minimum random rates of 50% of average driver positions for drugs and 10% for alcohol (49 CFR 382.305). We manage a compliant random pool, run the selections each period using a scientifically valid method — no employer picking names — and make sure the required percentage is actually tested.
The pool that makes it work
Owner-operators and small fleets can't run their own random program; a consortium pool is how you meet the requirement. We place your drivers in a DOT-compliant pool and handle the draws, notifications, and documentation.
Collected on-site
When a driver is selected, our own collectors across Nebraska and Kansas come to the terminal or job site — the driver is tested and back to work without a trip across the state.
Part of your C/TPA program
Random testing runs through our C/TPA & Consortium Program — one partner handling the pool, the selections, the collection, MRO review, and the records.

Compliance Requirements
Compliance Requirement
Minimum random rates — 49 CFR 382.305
FMCSA sets the annual minimum random testing rates at 50% of average driver positions for drugs and 10% for alcohol. The drug rate can drop to 25% only if the industry positive rate stays below 1% for two consecutive years — it currently does not.
Scientifically valid selection
Selections must be truly random — every driver has an equal chance each period, and employer-directed selection is prohibited. A selected driver must be tested as soon as possible after notification.
Owner-operators must be in a pool
An owner-operator cannot administer their own random program; participation in a consortium random pool is required.
Frequently Asked Questions
FMCSA minimums are 50% of average driver positions for drugs and 10% for alcohol each year, by a scientifically valid selection (49 CFR 382.305).
No. Selection must be genuinely random — employer-directed selection is prohibited. We run the draw so every driver has an equal chance each period.
Yes. An owner-operator can't run their own random program; participation in a consortium random pool is required to comply.
As soon as possible after notification. Our on-site collection across Nebraska and Kansas makes prompt testing easy.
Random testing runs through consortium membership — $129/year per company for a DOT-compliant pool — with per-test fees when a driver is selected ($75 in-clinic, $95 mobile).
