FMCSA Clearinghouse guide for owner-operators: registration, C/TPA, queries and consent

The FMCSA Drug and Alcohol Clearinghouse is a federal database of CDL drivers’ drug and alcohol program violations. Every employer of CDL drivers must use it, and an owner-operator is an employer. This guide walks through what that means when the employer and the driver are the same person.

Why an owner-operator has two roles

Part 382 defines an employer as any person who owns or leases a commercial motor vehicle and assigns drivers to it, including a person who drives their own truck. It defines a driver as anyone who operates a CMV that requires a CDL. An owner-operator meets both definitions at once.

The Clearinghouse mirrors that. You register an employer account for your USDOT number, and you also exist in the system as a driver identified by your CDL number and state. The employer account runs queries, designates a C/TPA and receives notifications. The driver identity is what gets queried and, if something goes wrong, where a violation is recorded.

Since you cannot query yourself in a way FMCSA accepts, and you cannot report your own violation, the rule requires an owner-operator to designate a consortium / third-party administrator (C/TPA) inside the Clearinghouse. This is written into 49 CFR 382.705(b)(6).

Step 1: register

1. Go to clearinghouse.fmcsa.dot.gov. That is the only real address. The site uses Login.gov for sign-in.
2. Create or use a Login.gov account. As of 2026, identity verification through Login.gov applies to FMCSA systems, so have a government ID ready.
3. Choose “Employer” as the registration type. You will be asked for your USDOT number. If you do not have one yet, get the number first through Motus and come back.
4. Answer the question about whether you are an owner-operator. Answer yes. The system then requires you to designate a C/TPA before you can complete the employer setup.
5. Purchase a query plan. Queries are 1.25 USD each. A one-driver carrier buys a small bundle; the credit does not expire.

You do not register separately as a driver unless you want to see your own record or need to give electronic consent for a full query. Drivers register with their CDL number and state, and the driver account is free.

Step 2: designate your C/TPA

In the employer dashboard, under “My Assistants” or the equivalent menu, invite your C/TPA by name. The C/TPA accepts the invitation from their side. Once linked, the C/TPA can run queries and report violations for your USDOT number.

Designation does two things. It satisfies 382.705(b)(6), and it gives the auditor something to check. At a new-entrant safety audit the auditor can see in the Clearinghouse whether the C/TPA designation exists and when it was made. A gap between the USDOT number issue date and the designation date is a question you will have to answer.

Step 3: the pre-employment query

Before a driver first operates a CMV for an employer, the employer must run a full query (49 CFR 382.701(a)). For an owner-operator that means before your first dispatch under your own authority, even if you have driven for years for someone else.

A full query needs the driver’s electronic consent inside the Clearinghouse. As the driver, you log in to your driver account and approve the request the employer account sent. If you do not have a driver account yet, this is the moment to create it. The query cannot complete without the consent, and a full query that is never completed is the same as no query at all.

A full query must also be run on any driver you hire. Do not put a new driver on the road while the consent request is pending.

Step 4: the annual limited query

At least once every 12 months, every employer must query each of its drivers (49 CFR 382.701(b)). A limited query is enough for the annual check. It asks a yes-or-no question: does the Clearinghouse hold any information about this driver?

A limited query does not need electronic consent. It needs a general consent signed by the driver and kept in the employer’s files. The consent can cover multiple years if it says so. Keep it with the driver qualification file. If the limited query comes back with a record, you have 24 hours to run a full query, and the driver must not perform safety-sensitive functions until the full query shows they are not prohibited.

Owner-operators forget the annual query more than anything else in this area. Put it on the same calendar day as the consortium renewal so it is done once a year without thinking.

Step 5: reporting

Three parties report into the Clearinghouse:

Who reports	What they report
Medical Review Officer	Verified positive, adulterated or substituted drug tests, and refusals determined by the MRO
Employer, or the C/TPA for an owner-operator	Alcohol results of 0.04 or higher, refusals not handled by the MRO, actual knowledge of use, negative return-to-duty and follow-up test results
Substance Abuse Professional	Initial assessment date and the date the driver is eligible for a return-to-duty test

An owner-operator does not report their own results. The designated C/TPA does. That is the practical reason the designation is mandatory, and why your C/TPA needs to know about any post-accident or reasonable-suspicion situation the same day.

What prohibited status means

A driver enters prohibited status when a violation is recorded and the return-to-duty process is not complete. In prohibited status, a driver cannot perform any safety-sensitive function, which for a truck driver means no driving. An employer who uses a prohibited driver violates 49 CFR 382.501 and, at a new-entrant audit, has an automatic failure item.

As of January 2026 about 328,000 drivers had at least one violation in the Clearinghouse and about 202,000 were in prohibited status. Most of those never started the return-to-duty process.

The CDL downgrade under Clearinghouse-II

The second Clearinghouse rule took effect November 18, 2024. State driver licensing agencies now receive prohibited-status notices from FMCSA and must remove the commercial privilege from the driver’s licence within 60 days. The driver keeps a non-commercial licence but the CDL or CLP is gone until the Clearinghouse shows the driver has completed the return-to-duty test.

For an owner-operator the sequence is short and hard to reverse. A positive test with no program in place, or a refusal, becomes a Clearinghouse record. The state downgrades the CDL. The truck sits until the driver finds a Substance Abuse Professional, completes the evaluation and any treatment, takes a return-to-duty test under direct observation, and the result is recorded. Follow-up testing then continues for at least 12 months and up to 5 years.

Return to duty, in brief

The process is in 49 CFR Part 40 Subpart O. The driver picks a qualified SAP, the SAP evaluates and prescribes education or treatment, the driver completes it, the SAP does a follow-up evaluation and reports eligibility to the Clearinghouse, the employer or C/TPA orders a return-to-duty test, and the negative result is reported. Only then does the status change. The C/TPA can manage the return-to-duty and follow-up schedule; the SAP fees are separate and paid by the driver.

Common owner-operator mistakes

• Registering as a driver only and never creating the employer account.
• Skipping the pre-employment full query because “I have been driving for twenty years.”
• Not designating a C/TPA, or designating one and then switching consortiums without updating the Clearinghouse.
• Letting the annual limited query lapse.
• Not keeping the signed general consent in the file.
• Hiring a second driver and running a limited query instead of a full one.

What Profirm does for you

Consortium members get the Clearinghouse handled from the same desk: we walk you through the employer registration, accept the C/TPA designation, run the pre-employment full query and the annual limited query, keep the consent forms, and report on your behalf when we must. At the time of writing the annual limited query is 15 USD per driver and the pre-employment full query is 25 USD per driver, in both cases including the 1.25 USD FMCSA query plan fee. C/TPA designation and the registration walkthrough are included with consortium enrollment, which is 99 USD a year for an owner-operator. Profirm is a private firm operating as a C/TPA under 49 CFR Part 40, not a government agency.
