If you run your own truck under your own USDOT number, FMCSA treats you as two people in the Drug and Alcohol Clearinghouse: the employer and the driver. Both have to be registered, and a consortium or third-party administrator (C/TPA) has to be designated in your account before you can run a single query. Here is which role to pick, what to have ready, the registration steps in order, and what to do once the account is open.
Your authority decides which role you register as
Federal rules say an employer who employs himself or herself as a driver must meet the employer requirements and the driver requirements at the same time (49 CFR 382.103). In the Clearinghouse that comes down to one question: whose USDOT number is the truck running under?
| Your situation | Register as | C/TPA designation |
|---|---|---|
| Leased on to another carrier, running under its USDOT number | Driver | Not yours to make. The carrier queries you |
| Own authority, you are the only driver | Employer and a Driver | Required before you can query or report |
| Own authority, you also hire drivers | Employer and a Driver | Required. Your drivers register as drivers |
The registration screen has a separate option for the second and third rows, Register as an Employer and a Driver. It registers your company and your own CDL in one pass, so you do not open two accounts.
What to have ready before you start
- Your USDOT number. Employer registration asks for it, and when you have one the Clearinghouse pulls your contact and company information from other FMCSA systems for you to verify.
- An FMCSA Portal account. FMCSA says a company that has, or should have, a USDOT number should request a Portal account before registering. The steps differ slightly with and without one.
- An email address you will keep. The Clearinghouse sends every notification to the email you sign up with, and that address cannot be modified later.
- Your CDL exactly as printed. State, number and details are checked against the national CDL database, and once verified they can no longer be edited.
- A C/TPA that has agreed to take you on. FMCSA asks employers to contact the C/TPA before sending a designation request. Enroll first, register second.

Get registeredRegistering as an employer and a driver, step by step
- Create a Login.gov account. Sign-in to the Clearinghouse runs through Login.gov. The password must be at least 12 characters, and you set up a second way to secure the account before you can continue.
- Answer the FMCSA Portal question. FMCSA publishes separate instructions for employers with and without a Portal account, so the next screens depend on your answer.
- Choose the role. Select Employer, then Register as an Employer and a Driver.
- Enter contact and company information. Name, address, phone and USDOT number. The company step asks you to indicate that you are an owner-operator, meaning an employer that employs itself as a CDL driver.
- Add and verify your CDL. Without a verified CDL you cannot view your own record or answer consent requests. If verification fails, check the entry; you can finish registering and fix the CDL later from your profile.
- Pick how you get notices. Email or U.S. Mail. FMCSA warns that mail can delay time-sensitive requests, which can affect whether you are allowed to drive.
- Designate your C/TPA and authorize what it can do on your behalf (next section).
Designating your C/TPA is required, not optional
A company with several drivers can choose whether to use a C/TPA. A one-truck owner-operator cannot. The rule requires an employer who employs himself or herself as a driver to designate a C/TPA to report on his or her own drug and alcohol use (49 CFR 382.705), and the Clearinghouse will not let an owner-operator run queries or report until that designation is in place.
- Search and designate. Type the C/TPA’s name in the search box, find it in the list and click Designate. The C/TPA has to be registered in the Clearinghouse itself to show up.
- Authorize the functions. The choices are Report Violations, Report RTD Information and Conduct Queries. An owner-operator must authorize at least one C/TPA to report violations and at least one to report negative return-to-duty information.
- Wait for the C/TPA to accept. The request shows as Pending until the C/TPA responds, then Active or Rejected. Until it is Active, the C/TPA cannot act for you.
- Changing C/TPAs. The account stays; you change the designation under Manage, C/TPAs. Any change to your C/TPA or its authorizations must be updated within 10 days (49 CFR 382.711).
After registration comes the query plan
Registration lets you into the system, but every query carries an FMCSA fee, so you need a query plan before anyone can run one. Plans are sold only by FMCSA inside the Clearinghouse, and a C/TPA is not allowed to buy one on your behalf. You buy it from your own employer account, and your designated C/TPA then runs queries against it.
Two queries matter from day one. Before a driver starts safety-sensitive work, the employer runs a full query, and the driver has to give consent electronically inside the Clearinghouse. After that, every driver on the payroll is queried at least once a year, and FMCSA’s owner-operator brochure is explicit that this includes yourself. A driver who refuses consent cannot drive for you (49 CFR 382.703).
Keeping the account in good standing
- Verify your authorized users every year. The names of the people allowed to report to or query the Clearinghouse for your company must be verified annually (49 CFR 382.711).
- Keep the registration valid. Query records must be kept for 3 years, and since January 6, 2023, an employer that keeps a valid registration meets that requirement through the Clearinghouse itself (49 CFR 382.701).
- Keep the testing program running. The Clearinghouse does not test anyone. A one-driver employer still has to be in a random testing pool of two or more covered employees (49 CFR 382.103), which is what a consortium is for.
- Expect your CDL to be checked too. Since November 18, 2024, the state CDL licensing official must obtain your Clearinghouse record when you apply to that state for a CDL or a learner’s permit (49 CFR 382.725).
Violations of the Clearinghouse rules carry civil and criminal penalties under federal law (49 CFR 382.727).
If you would rather hand the paperwork off, our Federal Clearinghouse service completes the registration for employers and CDL drivers on your behalf, sets up the annual query plan, and sends reminders for the annual queries and other required actions.
