Commercial Driver’s License Drug and Alcohol Clearinghouse
The Clearinghouse will improve highway safety by helping employers, FMCSA, State Driver Licensing Agencies, and State law enforcement to quickly and efficiently identify drivers who are not legally permitted to operate commercial motor vehicles (CMVs) due to drug and alcohol program violations. This secure online database will provide access to real-time information, ensuring that drivers committing these violations complete the necessary steps before getting back behind the wheel, or performing any other safety-sensitive function.

January 6, 2023: Clearinghouse Three-Year Mark
Employers must query the Clearinghouse to satisfy the employer requirement to identify prospective drivers who have committed drug and alcohol program violations.
FMCSA, along with the Department of Transportation (DOT), requires that persons subject to the commercial driver’s license (CDL) requirements and their employers follow alcohol and drug testing rules. These rules include procedures for testing, frequency of tests, and substances tested for.
Employers of drivers operating CMVs that require a commercial driver’s license (CDL) or commercial driver’s permit (CLP) are required to implement and conduct a drug and alcohol use testing program that complies with FMCSA and DOT requirements. Learn about drug and alcohol rules and how they affect your business. Access Employer Resources
An employer who employs himself/herself as a driver must comply with FMCSA drug and alcohol requirements that apply to both employers and drivers.
Drug and alcohol testing regulations are designed to help keep our roadways safe. Failure to consent to a required test will result in a driver being prohibited from performing a safety-sensitive function, such as operating a CMV. Learn about drug and alcohol regulations, including the types of tests required, when testing occurs, and drivers’ rights and responsibilities. Access Driver ResourcesDownload Factsheet
Frequently Asked Questions
Records of violations of drug and alcohol prohibitions in 49 CFR part 382, subpart B, including positive drug or alcohol test results and test refusals. When a driver with a drug and alcohol program violation completes the required Return-To-Duty (RTD) process, this information will also be recorded in the Clearinghouse.
To access the Clearinghouse once it is operational, a user will be required to request access from FMCSA by registering for the Clearinghouse. Authorized users will include:
- CDL/CLP Drivers
- Employers (this includes motor carriers and other employers with drivers operating CMVs that require a CDL or CLP)
- Consortium/Third-Party Administrators (C/TPAs)
- Medical Review Officers (MROs)
- Substance Abuse Professionals (SAPs)
- State Driver Licensing Agencies (SDLAs)
- Federal and State Enforcement personnel
No. The Clearinghouse will contain only drug and alcohol program violation information for employees subject to the testing requirements under the Federal Motor Carrier Safety Regulations in 49 CFR part 382. Employers must continue to request information from previous employers if the employee was subject to DOT drug and alcohol testing required by a DOT modal administration other than FMCSA (as required by § 391.23(e)(4)(B)).
No. Only results of DOT drug or alcohol tests or refusals may be reported to the Clearinghouse. While employers may conduct drug and alcohol testing that is outside the scope of the DOT testing requirements, positive test results or refusals for such non-DOT testing may not be reported to the Clearinghouse.
- Drivers will need to log into the Clearinghouse in order to electronically consent to requests from prospective and current employers needing to access full details about any drug and alcohol program violations in a driver’s history, as part of employment-related background checks. This is the only valid method for responding to this type of employer consent request, and failure to provide timely consent may result in a driver being prohibited from performing safety-sensitive functions for that employer.
- Drivers can log in at any time to view their individual driver record.
- If choosing to engage a Substance Abuse Professional (SAP), a driver must select the SAP through the Clearinghouse to initiate the Return-To-Duty (RTD) process.
To complete the actions outlined above, drivers will be required to register with the Clearinghouse. Sign up to receive an email notification once registration is open.
The Clearinghouse offers employers a centralized location to report drug and alcohol program violations and check that no current or prospective employee is prohibited from performing safety-sensitive functions, such as operating a CMV, due to an unresolved drug and alcohol program violation—that is, a violation for which the employee has not completed the Return-To-Duty (RTD) process. This check, or query, must be conducted as part of any pre-employment screening, and at least annually after an employee is hired.
Employers can also use the Clearinghouse to designate a Consortium/Third-Party Administrator (C/TPA); this is a required step for any employer that employs himself or herself as a driver.
To complete the actions outlined above, employers and C/TPAs will be required to register with the Clearinghouse. Sign up to receive an email notification once registration is open.
Medical Review Officers (MROs) and Substance Abuse Professionals (SAPs) must use the Clearinghouse to report required information about drivers.
MROs must report verified positive drug test results, or if a driver refuses to take a drug test.
SAPs must report on the Return-To-Duty (RTD) status of drivers working to resolve any open drug and alcohol program violations. These reports include the date of completion of the initial assessment and the date the driver becomes eligible for RTD testing.
Registration will be required to complete these actions. Sign up to receive an email notification once registration is open.
As of January 6, 2020, State Driver Licensing Agencies (SDLAs) will be able to query the Clearinghouse prior to completing licensing transactions.
