May an employer authorize a consortium/third-party administrator (C/TPA) to conduct queries in the Clearinghouse on their behalf?

Yes. Employers may designate a C/TPA or C/TPAs to conduct queries and/or report violations on their behalf. The C/TPA must be registered in the Clearinghouse before an employer can select the C/TPA, and C/TPAs must be designated by the employer before reporting drug and alcohol program violations or querying the Clearinghouse on their behalf.

An owner-operator (an employer that employs himself or herself as a commercial driver’s license (CDL) driver, typically a single-driver operation) must designate their C/TPA(s) as part of their Clearinghouse registration process.
