FMCSA Drug & Alcohol Clearinghouse: Annual Query Deadlines and Requirements

2026-09-18 · FleetClear

Most of the deadlines a small carrier tracks are calendar deadlines. MCS-150 is keyed to your USDOT number, UCR resets at the end of the year, IFTA runs on quarters. The Drug & Alcohol Clearinghouse annual query is different, and that difference is exactly why it gets missed: it is a rolling, per-driver deadline. There is no date in December when the whole fleet comes due. A driver hired on March 14 has a March deadline; the driver hired in August has an August one. Run a fleet of eight CDL drivers and you are carrying eight independent twelve-month clocks, none of which the Clearinghouse will chase you about.

What the Clearinghouse actually is

The Clearinghouse is FMCSA's federal database of drug and alcohol program violations by CDL and CLP holders, created under 49 CFR Part 382 Subpart G and live since January 6, 2020. It holds positive DOT test results, test refusals, employer actual-knowledge violations, and the return-to-duty and follow-up testing records that clear a driver to work again. Before it existed, a driver who failed a test at one carrier could quit, drive down the road and be hired by a carrier that never got a straight answer out of the previous employer. The database closed that gap by making the record follow the CDL rather than the employment file.

For an employer, that convenience comes with three standing obligations: query before you hire, query annually after that, and report violations you learn about within three business days. All three are audit items. Failure to run a pre-employment query under §382.701(a) is treated as an automatic-failure violation in a new entrant safety audit — one missed query on one driver can sink the audit outright.

The two query types, and when each is required

The distinction between a limited and a full query is where most carriers get tangled, because the two have different consent rules and different uses.

Two practical consequences. First, because the annual limited query runs on general written consent, you can collect that consent once at hire and keep it on file — but you must actually keep it, because an auditor will ask to see it alongside the query result. Second, a limited query that comes back "information exists" starts a 24-hour clock: you must run a full query within 24 hours, and the driver may not perform safety-sensitive functions until you do. If the driver has not registered in the Clearinghouse and cannot grant electronic consent, the driver stays parked. That is a real operational risk worth heading off by requiring driver registration at hire rather than discovering it on a Tuesday afternoon with a load on the dock.

The deadlines, in one place

The three-year manual check is no longer separate

During the Clearinghouse's first three years, employers had to do the job twice: run the Clearinghouse query and send the traditional written inquiry to every DOT-regulated employer the driver worked for in the previous three years, because the database had no history before January 2020. That transition period ended on January 6, 2023. Since then the full Clearinghouse query satisfies the three-year drug-and-alcohol violation check on its own. Note the limit of that statement: it retires only the drug-and-alcohol portion. The rest of the §391.23 investigation into safety performance history still has to happen, and carriers that quietly dropped the whole previous-employer inquiry after 2023 dropped more than the rule allowed.

Prohibited status now costs the license, not just the job

A driver with an unresolved violation sits in "prohibited" status and may not perform safety-sensitive functions until the return-to-duty process — SAP evaluation, education or treatment, a negative RTD test, and a follow-up testing plan — is complete and reported. That has always been true. What changed is the consequence outside your company. Under the Clearinghouse-II rule, effective November 18, 2024, state driver licensing agencies query the Clearinghouse before issuing, renewing, upgrading or transferring a CDL or CLP, and must downgrade the commercial privilege on the license of a driver in prohibited status, generally within 60 days of notification.

For a carrier this means a stale annual query is no longer a paperwork problem you can clean up later. A driver can be in prohibited status, lose the commercial privilege on the license, and keep showing up for work in a truck you dispatched — and the roadside inspection that finds it is an out-of-service event with your USDOT number on it. The annual query is the control that catches this, which is why letting it drift past twelve months is worse than it looks on a checklist.

Owner-operators are not exempt

If you drive under your own authority, you are both the employer and the driver, and the rules apply to you in both capacities. Because a driver cannot run queries on himself, §382.705 requires you to designate a consortium/third-party administrator to conduct queries and report violations on your behalf. One-truck operations routinely overlook this, register as drivers only, and are surprised during a new entrant audit to learn that the employer-side obligations were theirs the whole time.

Where this sits in the rest of the calendar

The Clearinghouse query is one of several deadlines that do not share a date with anything else. Your MCS-150 biennial update is keyed to your USDOT number, UCR resets December 31, IFTA runs on calendar quarters, and every driver carries an independent medical card expiry. Clearinghouse adds one clock per driver on top of all of it. Nothing about that is hard individually; the difficulty is entirely that nobody sends you a reminder.

Frequently asked

How often do I have to run a Clearinghouse query on my drivers?
At least once every 12 months for every CDL or CLP driver you employ. The clock runs per driver from the date of that driver's last query, not from a fleet-wide annual date, so a fleet of eight drivers has eight separate due dates.

What is the difference between a limited query and a full query?
A limited query only tells you whether information exists in the driver's Clearinghouse record; it runs on general written consent you collect outside the system. A full query returns the actual violation detail and requires the driver's electronic consent inside the Clearinghouse. Pre-employment checks must be full queries, and a limited query that comes back showing information exists must be followed by a full query within 24 hours.

Does an owner-operator have to register with the Clearinghouse?
Yes. A driver who employs himself or herself is both driver and employer for Clearinghouse purposes, and must designate a consortium/third-party administrator (C/TPA) to run the required queries and report violations on the company's behalf.

What happens if a driver is in prohibited status?
The driver may not perform any safety-sensitive function — including driving a CMV — until the return-to-duty process is complete. Since the Clearinghouse-II rule took effect on November 18, 2024, state driver licensing agencies are also notified and must downgrade the commercial driving privilege on the license within 60 days if the driver stays in prohibited status.
