The new requirement is intended to make it more difficult for drivers to continue operating after receiving a drug or alcohol violation.

“By November 18, 2024, as part of new federal regulations, drivers with a ‘prohibited’ status in the Drug and Alcohol Clearinghouse will lose or be denied their state-issued commercial driving privileges.” FMCSA warns truck drivers who drug-test positive will lose their CDLs starting late next year.

FMCSA's  Drug and Alcohol Clearinghouse is taking drivers caught using drugs off the roads. However, several thousand remain in prohibited driving status after failing their drug tests.

The rate of positive truck driver drug tests recorded in the Drug & Alcohol Clearinghouse in the first three months of this year remains on pace with last year’s, and the number of drivers who have yet to enroll in return-to-duty programs remains persistently low.

More than 10,000 positive drug tests for marijuana were reported to the federal Drug & Alcohol Clearinghouse through the end of May this year, distinguishing pot by far as the banned drug of choice for truck drivers failing tests, according to new numbers released in a Clearinghouse report June 11.

A group that manages the services of an estimated 12,000 drivers for major motion picture studios and independent and commercial production houses has been granted a five-year exemption from conducting full pre-employment queries of the Drug and Alcohol Clearinghouse for its drivers, FMCSA announced.
