Quick answer: Every employer of CDL drivers has to run a full Drug & Alcohol Clearinghouse query before a driver does any safety-sensitive work for them, and run a query on every current driver at least once every 12 months. The annual one can be a limited query. There’s no fixed calendar deadline. FMCSA tracks the 12 months on a rolling basis from the last query you ran on each driver. A driver in “prohibited” status can’t operate a commercial vehicle, and since November 18, 2024, their state has to downgrade their CDL as well.
Most fleet managers know the Clearinghouse exists. What’s harder to keep straight is the schedule. Drivers get hired on different dates, so each one has their own clock, and it’s easy to lose track of when each one runs out.
TruckDriversPRO centralizes driver, truck, and trailer documentation for fleets, with expiration visibility and exportable records.
The Two Queries Every Employer Runs
The first is the pre-employment query. It’s a full query, and it has to happen before the driver performs any safety-sensitive function for you, driving included. It needs the driver’s specific electronic consent, given inside the Clearinghouse, so the driver has to be registered before you can run it.
The second is the annual query on every CDL driver you currently employ. A limited query is enough to satisfy it. Every employer of CDL drivers has to be registered in the Clearinghouse, owner-operators included.
| Full query | Limited query | |
|---|---|---|
| When it’s used | Before hire, and as the follow-up when a limited query finds a record | Annual check on current drivers |
| Consent | The driver’s specific electronic consent, in the Clearinghouse, each time | A general consent obtained outside the Clearinghouse, which can cover more than one year |
| What you see | Details of violations and return-to-duty status | Only whether the driver’s record has information |
A limited consent has to state the period it covers. If a limited query shows the record has information, the next step is a full query, with the driver’s electronic consent.
The Annual Deadline Is Rolling
You’ll see some guides describe a fixed January deadline. FMCSA’s own FAQ describes something different. The annual query is tracked on a rolling 12-month basis from the last query you ran on that driver. FMCSA’s example: a query on December 1 means the next one isn’t due until the following December 1. A pre-employment query starts that clock the same way.
FMCSA also allows an employer-defined 12-month cycle, as long as the annual requirement in §382.701(b) is still met. Either way, you need to know each driver’s last query date.
When a Driver’s Record Changes
If a driver you’ve queried has new information recorded within 12 months of a pre-employment or annual query, you get an email about it. FMCSA says to run a full follow-up query within 24 hours. The driver has to give specific electronic consent for it, and if they refuse, you have to take them off safety-sensitive duty until a full query is done and the result is back. They can go back to work only if the status comes back “not prohibited.”
The follow-up also counts as your annual query and restarts the rolling 12 months.
That 24-hour window is the part worth planning for. Every registered user on the employer’s account gets the notification, so it helps to decide in advance who acts on it.
What “Prohibited” Means for the Driver’s CDL
A driver in prohibited status can’t perform safety-sensitive functions, including driving a commercial vehicle, until they complete the return-to-duty process. Since November 18, 2024, the state has to act on the license too. The state licensing agency starts a downgrade to remove commercial privileges within 60 days of being notified. A driver who completes return-to-duty before the downgrade finishes is no longer subject to it.
States also have to check the Clearinghouse before issuing, renewing, upgrading, or transferring a CDL or CLP. To get commercial privileges back, the driver completes return-to-duty, their status changes to “not prohibited,” and the state can reinstate.
For a carrier, a prohibited driver is no longer a short scheduling gap. It can mean the driver is off the road for as long as the process takes.
What You Still Need to Keep on File
Less than many fleets assume. The Clearinghouse keeps a history of every query you run, including ones run by a designated administrator on your behalf, and a valid registration satisfies the record retention rules for those queries. Keeping copies in the driver qualification file is optional.
Consent is the exception. You have to keep records of drivers’ limited consent for three years and be able to produce them on request. They don’t have to live in the DQF.
One more case: if a driver was previously regulated by another DOT agency, such as rail, transit, or aviation, those employers’ responses still go in the driver investigation history file, because those violations don’t appear in the Clearinghouse.
How This Fits the Driver Qualification File
The pre-employment query is how an FMCSA-regulated employer meets the drug and alcohol history part of the previous-employer investigation under §391.23(e) for earlier FMCSA-regulated employers. Inquiries made outside the pre-employment query process don’t satisfy it. If it’s on your hiring checklist, it belongs next to the other items in your Driver Qualification Files.
Frequently Asked Questions
Is there a fixed annual deadline for Clearinghouse queries? No. FMCSA tracks the annual query on a rolling 12-month basis from your last query on each driver, or on another 12-month cycle you set, as long as the annual requirement is met.
Does a limited query satisfy the annual requirement? Yes. If the limited query shows the driver’s record has information, you then need a full query, which requires the driver’s electronic consent in the Clearinghouse.
How much does a Clearinghouse query cost? FMCSA lists a flat rate of $1.25 per query. Registration and other Clearinghouse activities have no fee.
Do owner-operators have to query the Clearinghouse on themselves? Yes. An owner-operator is both the employer and the driver, so they follow both sets of requirements and have to designate a consortium or third-party administrator to handle reporting.
What happens to a driver’s CDL when their status is “prohibited”? Since November 18, 2024, the state licensing agency has to remove commercial driving privileges, starting the downgrade within 60 days of being notified. The driver gets them back by completing return-to-duty and reaching “not prohibited” status.
