Enrolling There are no costs for drivers to sign-up with the FMCSA Clearinghouse. Queries Employers are charged a flat rate of $1.25 per query (pre-employment or annual). Queries never expire. Query Plans Employers are required to purchase a query plan, which allows them (or their third-party administrator) to conduct queries. Third-party administrators cannot purchase queries on behalf of employers. Find more information on Query Plans here.
