FMCSA Drug & Alcohol Clearinghouse
The FMCSA Drug & Alcohol Clearinghouse contains information on all violations of the FMCSA Drug and Alcohol Testing Program incurred by drivers who hold a commercial driver’s license (CDL) or commercial learner’s permit (CLP). These violations include:
- Report for duty/remain on duty for safety-sensitive function with alcohol concentration of 0.04 or greater or while using any drug specified in the regulations (Part 40), other than those prescribed by a licensed medical practitioner
- Alcohol use while performing, or within four hours of performing, a safety-sensitive function
- Alcohol use within eight hours of an accident, or until post-accident test, whichever occurs first
- Test positive for use of specified drugs
- Refusing to submit to a required alcohol or drug test
What can a driver do about inaccurate information?
If an employer or medical review officer (MRO) enters violation information in your Clearinghouse record that you believe to be inaccurate, you may petition FMCSA to review the information by submitting a driver petition in FMCSA’s DataQs system. Download the Submitting a Petition for Data Review Job Aid for more details.
Note that you are permitted to challenge only the accuracy of information in the Clearinghouse reflected in one of the following categories:
- Accuracy of data in driver record
- Actual knowledge violation did not result in a conviction
- Actual knowledge violation did not comply with reporting requirements
- Refusal to test violation did not comply with reporting requirements
Drivers may not use the petition process to challenge the accuracy of test results or refusals.
How can drivers view their Clearinghouse record?
To view a Clearinghouse record electronically, a driver must be registered in the Clearinghouse and have verified his or her CDL or CLP information.
If you have completed registration but not verified your CDL/CLP information, log in to the Clearinghouse and navigate to My Driver Profile and click Add CDL#.
Having trouble verifying a CDL?
If your CDL number has special characters (such as spaces or dashes), try entering the CDL number with or without these characters, as requirements vary by State. If your CDL number begins with a zero, or multiple zeroes, be sure to enter these.
