49 CFR Part 382 & Part 40
No jargon, no scare tactics. Here is what a DOT-regulated employer has to do, why a consortium exists, and what happens if you skip it.
A negative drug test before a driver performs any safety-sensitive function. No exceptions.
Selections drawn from a pool at federally set rates, spread unpredictably across the year.
Required after qualifying accidents, within strict time windows. A driver cannot refuse.
When a trained supervisor observes specific, articulable signs. Requires documented supervisor training.
After a violation, following completion of the SAP process. Must be an observed collection.
A SAP-directed schedule after return to duty. Can continue for up to five years.
| Test type | Annual rate |
|---|---|
| Drug | 50% of average driver positions |
| Alcohol | 10% of average driver positions |
Unchanged for a sixth consecutive year. Selections must be genuinely random and spread reasonably through the year — you cannot do them all in December.
A one-truck operator can't run a random selection on a pool of one — statistically it's meaningless, and the FMCSA knows it. So owner-operators are required to join a consortium: a pooled group of drivers from many employers, drawn from together.
Larger fleets aren't required to use a consortium, but almost all small ones do, because the alternative is running a defensible randomization program, maintaining the records, contracting an MRO, and managing Clearinghouse reporting yourself. The consortium administrator — the C/TPA — does all of that.
We're not going to run scare tactics at you — but the honest answer is that this is one of the cheapest obligations FMCSA places on a carrier and one of the most consequential to miss.
A missing or lapsed testing program is a finding in a new-entrant safety audit and can put your operating authority at risk. Brokers and shippers increasingly ask for proof of enrollment before they'll give you a load. And failing to run Clearinghouse queries is the single most common violation found in audits — more than 18,000 were issued between 2021 and 2025.
The cost of compliance is a few hundred dollars a year. The cost of non-compliance is your authority.
