How to make a query in the FMCSA Clearinghouse

A query is an electronic check-in the Clearinghouse, conducted by an employer or their designated C/TPA, to determine if current or prospective employees are prohibited from performing safety-sensitive functions, such as operating a commercial motor vehicle (CMV), due to unresolved drug and alcohol program violations.

Queries in the Drug & Alcohol Clearinghouse (DACH) are conducted by employers or their designated Consortium/Third Party Administrators (C/TPA).  Full queries are required for new driver applicants being hired by the company. The limited query is used for the required annual query of all drivers.

For the limited query the employer must obtain a paper consent.  This is obtained outside the Clearinghouse. Employers may obtain a multi-year general consent from the driver for limited queries. A sample limited consent form from is available. is a private company dedicated to providing assistance to all Clearinghouse users.

An employer must be registered in the FMCSA Clearinghouse and have purchased a Query Plan in order to run a query.  A driver must be registered in the FMCSA Clearinghouse in order to provide electronic consent for a full query. 

In order to run queries, the employer must purchase a query plan.  The cost of queries are $1.25 each, only the employer can purchase the query plan.  These are the only fees charged for use of the Clearinghouse. These query plans must be purchased direct from the FMCSA Clearinghouse.

  10. Click on Send Consent Request

For a full query once you send the consent request your query will be performed when the driver provides the consent.  If the driver does not provide consent the driver is not allowed to operate in a FMCSA covered position. For new drivers coming onboard your company, they cannot drive until you get back a clear record on the query.

Queries can also be conducted with a bulk upload file when you have many drivers to query.  These bulk orders are placed into batches. These batches are processed each night, between the hours of 8:00 p.m. and 8:00 a.m. ET., in order to avoid overloading the system during peak user hours.
