FMCSA Clearinghouse annual query: how to run it and keep track
What the FMCSA Clearinghouse annual query requires under 49 CFR 382.701, limited versus full queries, consent, and how to keep every driver on schedule.
If you employ CDL drivers who are subject to DOT drug and alcohol testing, you have to query the FMCSA Drug and Alcohol Clearinghouse for each of them at least once a year. It takes a few minutes per driver in the Clearinghouse portal. The hard part is not running the query. It is remembering, for every driver, that the year is up.
This guide explains what the annual query requirement says, the difference between a limited and a full query, the consent each one needs, and a simple routine for keeping every driver on schedule.

What the rule says
The requirement is in 49 CFR 382.701(b), which you can read at Cornell's Legal Information Institute. In plain terms:
- Employers must query the Clearinghouse at least once per year for every employee subject to drug and alcohol testing under Part 382, to find out whether the Clearinghouse holds information about them.
- A limited query can be used to meet the annual requirement instead of a full query.
- If a limited query shows that information exists about the driver, the employer must run a full query within 24 hours. If it does not, the driver may not keep performing safety-sensitive functions until the full query is done and shows no prohibition.
The same section also requires a full query before a new driver performs safety-sensitive functions for you. That pre-employment query is a hiring step and is separate from the annual one.
Section 382.701 also requires you to keep a record of each query and the information you received for three years.
Limited query or full query
| Limited query | Full query | |
|---|---|---|
| What it tells you | Whether any information about the driver exists in the Clearinghouse | The details of any violations and return-to-duty status |
| Driver's consent | A general written consent, given to you outside the Clearinghouse | Electronic consent given by the driver inside the Clearinghouse |
| Typical use | The annual query | Pre-employment, and the follow-up when a limited query finds something |
Most carriers use limited queries for the annual requirement. They need only the paper consent you already have on file, and the result is usually "no information found," which closes the item for the year.
Consent for the limited query
Before you run a limited query you need the driver's written consent. It is collected outside the Clearinghouse, on a form you keep. The consent can cover more than one year, so many carriers have each driver sign one that lasts for as long as they work there, and keep it on file. Check what your existing consent forms say. If they cover a single year, you will need new signatures before the next round of queries.
If a limited query shows information exists, the driver has to log in to the Clearinghouse and give consent for the full query there. That only works if the driver is registered, so it helps to have drivers register when they join rather than in the middle of a 24-hour window.
Running the query
The steps in the portal, at a high level:
- Register as an employer in the Clearinghouse, or designate a consortium/third-party administrator (C/TPA) to run queries for you.
- Buy a query plan. Queries are paid for in the Clearinghouse. Check the current price on the FMCSA site.
- Run the limited query for each driver, using their CDL number and state, which you have on file.
- Read the result. "No information found" means you are done for that driver this year. If it shows information exists, start the full query process the same day.
- Record it. Note the date, who ran it and the result in your records, and set the date for next year.
You can query several drivers in one session. Many small carriers run all of their annual queries on the same day each year.
Picking a schedule: rolling or one month a year
The rule says at least once per year. There are two common ways to schedule it:
- Rolling 12 months. Each driver's next query is due 12 months after their last one. This is the conservative reading, because no driver ever goes more than a year between queries. It spreads the work across the year, one or two drivers at a time.
- One month a year for everyone. You pick a month, say March, and query every driver then. It is simple to remember, and a session in the portal handles the whole fleet. The catch is new drivers: someone hired in October gets a pre-employment full query then, and should be in the following March session, not the one after.
Either works if no driver goes more than 12 months between queries. Pick one and write down which you use, so the next person running the program does the same.
A routine for small fleets
- Every active CDL driver has a signed general consent for limited queries on file, covering the current year.
- Every driver has a recorded date for their last annual query.
- You know each driver's next due date and have a reminder set before it.
- Drivers are registered in the Clearinghouse, so a full query can happen within 24 hours if needed.
- Each query's date and result are kept for three years.
- Results stay in your confidential drug and alcohol records, not in shared calendars, spreadsheets or reminder emails.
The last point matters. A due date is not sensitive. A query result can be. Keep the two apart.
The annual query and the annual MVR review
The Clearinghouse query (Part 382) and the annual review of each driver's motor vehicle record (Part 391) are separate rules, but both come due once a year per driver. Tracking them side by side means one place to look. Our guide to the annual review of driving record covers the MVR side.
Where DQ Calendar fits
DQ Calendar tracks each driver's annual Clearinghouse query date next to their annual MVR review. In settings you choose rolling 12 months from each driver's last query, which is the default, or a fixed month each year. It emails you before each query is due. After a session in the portal, "Mark Clearinghouse done for all" records the date for every driver you queried in one step.
It never runs queries and never sees results. There is no connection to the Clearinghouse: you query in the portal, then record the date in DQ Calendar. It stores dates and the notes you type, and the note field asks you not to enter results.
Stay ahead of every driver's annual MVR review and Clearinghouse query
DQ Calendar tracks each driver's annual MVR review and Clearinghouse query, emails you before they are due, and keeps a dated, printable log of what you recorded.
