An employer will be required to conduct a query of the Clearinghouse for each currently-employed CDL-driver at least once a year. This annual query may be either full or limited. The annual query is the minimum requirement and employers may conduct queries more often, as long as they obtain the employee’s consent.
A prospective employer must conduct a full pre-employment query of the Clearinghouse prior to employing a driver to perform a safety-sensitive function. The difference between full and limited queries is discussed below.
