The FMCSA Drug and Alcohol Clearinghouse, registered in one sitting
The Clearinghouse is FMCSA's database of CDL drug and alcohol violations: employers query it before hiring and every year after, and violations are reported into it. A one-truck owner-operator registers twice, as the employer and as the driver, then hands the ongoing work to a consortium. Non-CDL operations do not register for the DOT program at all.

Queries, explained before you buy any
Full query
Shows the details of any violation on a driver's record. Required before a driver's first safety-sensitive work for you, which for an owner-operator means a full query on yourself before your first load. The driver gives electronic consent inside the Clearinghouse.
Limited query
Says only whether a record exists, no details. Satisfies the annual requirement and needs a general written consent, which can cover multiple years. If it finds something, a full query must follow within 24 hours.
Annual query
Every employer queries each CDL driver at least once a year. One limited query per driver per year meets it; your C/TPA can run it for you once designated.
Queries cost $1.25 each, limited or full, bought in prepaid bundles that do not expire, as published October 2026 on the Clearinghouse site. The employer buys the plan; a C/TPA can run queries from your plan but cannot buy one for you. A one-truck carrier typically needs a handful a year, so this is a few dollars, not a line item.
Source: FMCSA Clearinghouse query plans · data as of Oct 2026Why a C/TPA makes this a one-time chore
Owner-operators are required to designate a consortium/third-party administrator in the Clearinghouse. Once designated, the C/TPA runs your annual queries, reports any violations it handles, and keeps the Clearinghouse side in step with your random program. You log in once a year to confirm nothing changed, instead of becoming a part-time compliance clerk.
§ 49 CFR 382.705(b)(6) · checked Oct 2026The registration walkthrough, box by box
Described in words, not screenshots, because the screens change and the steps do not. Each box notes what to put there.
- 01Create a Login.gov account
What to put here
The Clearinghouse signs you in through Login.gov. Use an email you will still own in five years and set up two-factor on your phone, not a shared device.
login.gov - 02Register at the Clearinghouse in the employer role
What to put here
Choose the employer role, enter your USDOT number, and indicate you are an owner-operator. FMCSA verifies the company against its registration records, so the name and USDOT must match exactly.
clearinghouse.fmcsa.dot.gov - 03Link your driver role
What to put here
Enter your CDL number and issuing state so the driver record connects to the same account. This is the dual role made literal: one login, two hats.
- 04Buy a query plan
What to put here
A small bundle covers a one-truck operation for years. Queries are $1.25 each as published October 2026, and bundles do not expire.
- 05Designate your C/TPA
What to put here
Search for your consortium by name and send the designation; they accept it on their side. Required for owner-operators. Switching consortiums later means updating this designation.
- 06Consent to and run your pre-employment full query
What to put here
As the driver, approve the electronic consent; as the employer, run the full query on yourself. Clean result: you are clear on the Clearinghouse side for your first load.

The five snags that stall registration
- 01Company name or USDOT that does not match FMCSA's registration record exactly, down to the LLC suffix. Fix the registration first, then the Clearinghouse.
- 02Two Login.gov identities, one for the driver and one for the employer. Keep one identity with both roles, or consent requests land in the wrong inbox.
- 03A designation sent but never accepted. The C/TPA must accept on its side; check that the status shows accepted before you assume you are covered.
- 04A query run before consent was granted. The full query waits on the driver's electronic consent, which for you means approving your own request.
- 05An expired Login.gov phone number. Update two-factor before you change phones, not after, because locked-out employers cannot run the annual query.
The annual query, so it never sneaks up
Within a year of your pre-employment query, and every year after, each CDL driver needs at least a limited query. Keep the general consent on file, let your C/TPA run it, and put the anniversary on your calendar anyway. If you ever find yourself in a prohibited status, know that since November 2024 state licensing agencies must remove CDL privileges from drivers in prohibited status until the return-to-duty process is complete, which makes the Clearinghouse a licensing matter, not just a hiring one.

Q-01What is the FMCSA Drug and Alcohol Clearinghouse?
FMCSA's online database of drug and alcohol program violations by CDL drivers. Employers must query it before hiring a CDL driver and at least yearly after, and violations, return-to-duty progress and refusals are reported into it. It exists so a violation follows the driver from company to company.
Q-02Do owner-operators need to register in the Clearinghouse?
If the truck requires a CDL and you hold your own authority, yes, in both roles: as the employer who runs queries and as the driver who consents to them. You must also designate a C/TPA. Non-CDL operators are outside the DOT program and do not register for it.
Q-03How do I register as an owner-operator in the FMCSA Clearinghouse?
Create a Login.gov account, register at clearinghouse.fmcsa.dot.gov in the employer role with your USDOT number, mark yourself an owner-operator, link your CDL as the driver, buy a small query plan, designate your C/TPA, then consent to and run your pre-employment full query. The walkthrough above takes most carriers under an hour.
Q-04How do I register as an owner-operator if I already have a driver account?
Add the employer role to the same Login.gov identity rather than creating a second account. Enter your USDOT number and owner-operator status so both roles sit together; duplicate accounts are the most common cause of consent and query confusion later.
Q-05Do I need a Clearinghouse account for my new authority?
If you will drive a CDL truck under that authority, yes, and before the first load: the pre-employment full query has to be run before safety-sensitive work begins. If your trucks are non-CDL, the DOT Clearinghouse does not apply to your operation.
