FMCSA Clearinghouse: Updated User Brochures Now Available

Updated User Brochures Now Available

FMCSA has posted updated materials to help CDL drivers and their employers register for and get started using the Drug and Alcohol Clearinghouse.

Why should employers register?

• Register for the Clearinghouse.
• Conduct queries on all potential new hires, and at least annually on all current employees who perform safety-sensitive functions, such as operate a commercial motor vehicle.
• Report driver violations (positive alcohol tests, test refusals not reported by a medical review officer [MRO], and actual knowledge of violations).

Why should drivers register?

Drivers must be registered in the Clearinghouse, with a verified CDL number, to respond to employer consent requests. They can also view their own Clearinghouse record at any time.

How should self-employed CDL drivers register?

CDL drivers who operate under their own authority (often called “owner-operators,” typically a single-driver operation) must register as an employer and designate a consortium/third-party administrator (C/TPA) in the Clearinghouse. Owner-operators can also add their CDL information to add a driver role, which allows them to respond to query consent requests from their C/TPA.
