Do you Need Help Registering Your
Company Into The DOT Clearinghouse?

What is the Drug and Alcohol Clearinghouse?

Mandatory reporting by employers to the Clearinghouse begins Jan. 6, 2020.

Employers will be required to conduct both electronic queries and manual inquiries with previous employers to check CDL driver violation histories from the past three years as required by the FMCSA’s drug and alcohol use testing program.

Employers are required to query all current employees at least annually. All queries need driver consent. The type of consent depends on the query type, limited or full.

If a full query is needed for a driver, the driver will need to register with the Clearinghouse, log in, and grant electronic consent.

On Jan. 6, 2023, employers will be required to use the Clearinghouse exclusively when it comes to identifying prospective drivers who have committed drug and alcohol program violations.

Three years of violation data will by then be stored in the Clearinghouse system, making inquiries to previous employers unnecessary.

An owner-operator (an employer who employs himself or herself as a CDL driver, typically a single-driver operation) is subject to the requirements pertaining to employers as well as those pertaining to drivers.

Under the Clearinghouse final rule, an employer who employs himself or herself as a CDL driver must designate a consortium/third-party administrator (C/TPA) to comply with the employer’s Clearinghouse reporting requirements (§ 382.705(b)(6)).
