DOT’s Clearinghouse faces a key test as fleets will likely flood the system in the coming weeks

November 4, 2020

The CDL Drug & Alcohol Clearinghouse, which faced frequent crashes and lingering technical hang-ups in its initial rollout earlier this year, will face another big test in the coming eight weeks as hundreds of thousands of motor carriers and owner-operators are expected to hit the system for the first time.

Due by Jan. 5, 2021, fleets of all sizes must have run at least one query of all of their drivers to remain compliant. The Clearinghouse regulation, which took effect Jan. 5, 2020, requires fleets to run a once-annual limited query for all of its drivers. Those limited queries differ from pre-employment queries in that they only check to see whether a driver shows up in the Clearinghouse, not what information is within the Clearinghouse for any particular driver.
