Drug & Alcohol Clearinghouse

Access the Drug and Alcohol Clearinghouse

How will you use the Clearinghouse?

Employers, or their designated consortia/third-party administrators (C/TPAs), must now conduct queries, with driver consent, for all prospective CDL drivers, and annually for all currently-employed drivers.

Employers must be registered prior to hiring a new driver, and before the annual queries can be completed. Only drivers seeking new employment must be registered. Employers, or their designated C/TPAs, and medical review officers (MROs) must now report drug and alcohol program violations.

NOTE: For employers or drivers who, due to extremely high traffic volume, experienced issues last week registering or conducting queries, those issues have been addressed. To ensure compliance, please retry completing those actions at this time.
