Registration for the FMCSA Drug and Alcohol Clearinghouse happens at clearinghouse.fmcsa.dot.gov using a Login.gov account. Employers link a USDOT Number, an FMCSA Portal account, and an EIN; CDL and CLP drivers enter their license details, which the system verifies against the Commercial Driver’s License Information System (CDLIS). Once you’re registered, employers can run queries and report violations, and drivers can grant electronic consent, view their own record, and designate a Substance Abuse Professional if needed.
Who Needs to Register
The Clearinghouse is a secure federal database that tracks CDL and CLP drivers’ drug and alcohol program violations in real time, and access to it depends on the role you register under.1Federal Motor Carrier Safety Administration. What is the Drug and Alcohol Clearinghouse (Clearinghouse) and What Information Does It Contain?
Employers. Every FMCSA-regulated employer of CDL drivers must register. That covers motor carriers of all sizes and owner-operators who employ themselves as CDL drivers. Registration is what lets you conduct the queries the regulations require and report violations you’re obligated to report.2Federal Motor Carrier Safety Administration. Drug and Alcohol Clearinghouse – Registration
CDL and CLP drivers. Drivers aren’t technically required to register, but in practice you can’t avoid it. A pre-employment query is a full query, and a full query needs your electronic consent inside the Clearinghouse. Without an account, you can’t provide that consent, and an employer can’t put you behind the wheel of a commercial motor vehicle.2Federal Motor Carrier Safety Administration. Drug and Alcohol Clearinghouse – Registration Registration also lets you view your own Clearinghouse record and designate a Substance Abuse Professional if the return-to-duty process ever applies to you.
Service agents. Consortia/Third-Party Administrators (C/TPAs), Medical Review Officers (MROs), and Substance Abuse Professionals (SAPs) each register in their own capacity so they can report violation and return-to-duty information.3Federal Motor Carrier Safety Administration.

What You Need Before You Start
Every registrant needs a Login.gov account. That’s the universal federal credential the Clearinghouse uses to sign you in. If you don’t have one, set it up first; the Clearinghouse registration flow will send you to Login.gov the first time you try to sign in.
Employers should have these ready:
- Your USDOT Number, which the Clearinghouse uses to pull your company information from other FMCSA databases.4Federal Motor Carrier Safety Administration. Drug and Alcohol Clearinghouse Registration and Requirements for Owner-Operators
- Your FMCSA Portal user ID and password. Registration prompts you to link this existing account so the system can confirm you actually have authority over the USDOT Number you entered.
- Your Employer Identification Number (EIN), used to verify your company’s identity.
Drivers need their CDL or CLP number, the issuing state, and basic personal identification. The Clearinghouse verifies that license information against CDLIS during registration, and you can’t respond to consent requests or view your record until the verification clears.5Federal Motor Carrier Safety Administration. Clearinghouse Registration – CDL Drivers
How Employers Register
Start at the Clearinghouse website, sign in with your Login.gov credentials, and select the “Employer” role. Enter your USDOT Number and EIN so the system can link your company to the account. When prompted, provide your FMCSA Portal user ID and password to verify you control that USDOT Number.
During registration, you designate a Clearinghouse Administrator. The Administrator manages other users on your account and handles reporting and query responsibilities. Larger carriers can have the Administrator invite assistants to perform tasks on the company’s behalf.
Owner-Operators Have an Extra Step
If you’re an owner-operator, you employ yourself as a CDL driver, and the regulations don’t let you report your own violations or run queries on yourself without oversight. You must designate at least one C/TPA during registration.6Federal Motor Carrier Safety Administration. Drug and Alcohol Clearinghouse – How to Designate Your C/TPA Contact your C/TPA before designating them in the system so they know it’s coming. Once designated, the C/TPA can conduct queries and report violations for you. If you ever commit a drug or alcohol violation, your C/TPA is the one who reports it.
You’ll also need to purchase a query plan before your C/TPA can run any queries on your behalf. Queries cost $1.25 each under the individual plan, whether limited or full, and purchased queries don’t expire.7Federal Motor Carrier Safety Administration.

How CDL and CLP Drivers Register
Driver registration follows the same starting point: create a Login.gov account, go to the Clearinghouse website, and choose the “Driver” role. Student drivers already employed by a motor carrier also select “Driver,” but a student in a training program that isn’t affiliated with a motor carrier chooses “Student Driver” instead.5Federal Motor Carrier Safety Administration. Clearinghouse Registration – CDL Drivers
Enter your CDL or CLP details so the system can verify them against CDLIS. Once verified, review and accept the terms and conditions. Your driver dashboard becomes the place where you respond to employer consent requests, review your Clearinghouse record, and manage your account.
One thing worth knowing before you sit down to register: if a current or prospective employer sends you a consent request for a full query and you decline, the Clearinghouse tells the employer you’re prohibited from performing safety-sensitive functions.8Federal Motor Carrier Safety Administration. Clearinghouse – Responding to Consent Requests Refusing consent has the same practical effect as having a violation on your record. The employer can’t let you drive.
What Registration Lets You Do
Registration is the door, not the destination. Once your account is active, the compliance obligations kick in.
Employers must run a full pre-employment query before any driver performs safety-sensitive functions, with no grace period.9eCFR. 49 CFR 382.701 – Drug and Alcohol Clearinghouse Every currently employed driver must also be queried at least once every 12 months, on a rolling 365-day cycle from the last query on that driver.10Federal Motor Carrier Safety Administration. What Is the Annual Requirement for Employee Queries and How Is It Tracked? Annual queries can be limited queries, which use a general consent form signed outside the Clearinghouse and can cover more than one year if the form specifies a timeframe.11Federal Motor Carrier Safety Administration. What Is the Difference Between a Full and Limited Query If a limited query returns “Record(s) Found,” the employer has 24 hours to complete a full query, or the driver must be pulled from safety-sensitive duties until the full query clears.
Employers also carry a reporting duty. A drug or alcohol program violation must be reported by the close of the third business day after you learn about it, including actual-knowledge violations such as direct observation, a traffic citation for driving a CMV under the influence, or the employee’s own admission.12Federal Motor Carrier Safety Administration. What Is the Timeframe in Which an Employer Must Submit a Report of an Employee’s Drug and Alcohol Program Violation to the Clearinghouse?13Federal Motor Carrier Safety Administration. What Is Considered Actual Knowledge of a Violation?
For drivers, registration means you can log in, see what employers see, respond to consent requests, and, if you ever have a violation, designate a SAP to start the return-to-duty process. Both you and the SAP have to be registered for the designation to work.14Federal Motor Carrier Safety Administration. How to Designate a Substance Abuse Professional
One Boundary Worth Knowing
Registration replaces the old manual inquiry process for FMCSA-regulated employers, but not for every DOT agency. If a prospective driver previously worked for an employer regulated by a different DOT agency, such as the Federal Railroad Administration or the Federal Transit Administration, you still need to contact that prior employer directly, because those agencies don’t report to the Clearinghouse.15Federal Motor Carrier Safety Administration. Pre-Employment Investigations After January 6, 2023 Your Clearinghouse account, on its own, doesn’t cover that history.
