202,345 Truckers, Prohibited

Every commercial driver who fails or refuses a drug or alcohol test has that violation recorded in the Drug and Alcohol Clearinghouse, the database the Federal Motor Carrier Safety Administration has run since January 6, 2020 under 49 C.F.R. 382.705.▸ The moment that record posts, federal rule bars the driver from operating a commercial motor vehicle — no grace period — until they complete a multi-step return-to-duty (RTD) process. The Clearinghouse's December 2025 Monthly Summary Report puts the current scale of that bar at 202,345 drivers in "Prohibited" status as of January 2, 2026 — up from 190,402 six months earlier, per the June 2025 report.

Positive drug tests account for the overwhelming majority of Clearinghouse violations.▸ Since the database opened, employers and medical review officers have reported 345,405 positive substance results — and marijuana metabolite alone accounts for 206,394 of them, roughly 60% of every positive test logged, according to the same December 2025 report. That single substance outnumbers the next four most common categories combined.

A positive test doesn't just cost a driver their next shift — it starts a clock that, for most, never runs out.▸ Of the 328,431 CDL and CLP holders with at least one violation on record as of January 2, 2026, 202,345 are still prohibited from driving. Break that group down further and 159,226 — 78.7% of everyone currently prohibited — haven't taken the first step: no substance-abuse-professional evaluation requested, nothing. Another 19,401 are somewhere inside that SAP evaluation (request sent, professional assigned, assessment complete, or the request declined outright), and 23,718 have cleared enough of the process to be eligible for the RTD test itself. Only the 126,086 drivers on the other side of the chart — those who've posted a negative RTD test or finished their follow-up testing plan — are legally clear to drive again.

Value the 159,226 who haven't started the process at the Bureau of Labor Statistics' median annual wage for heavy and tractor-trailer truck drivers — $57,440, per the May 2024 Occupational Employment and Wage Statistics — and that stalled population represents roughly $9.1 billion a year in driving income nobody in it is currently earning.▸ Include every prohibited driver, not just the ones who haven't started, and the figure rises to about $11.6 billion.

The population of prohibited drivers didn't just grow — it grew because a second rule started forcing the issue.▸ Under the Clearinghouse-II final rule, finalized in October 2021 with a compliance date of November 18, 2024, every state driver's licensing agency must now query the Clearinghouse before issuing, renewing, transferring, or upgrading a CDL or CLP — and must downgrade the license of anyone the database shows as prohibited. For the rule's first three years, a prohibited driver could still hold a valid paper CDL even while barred from safety-sensitive duty; states had no mandate to act on that status. Since November 2024, they do, and the prohibited count has climbed accordingly: 190,402 in July 2025 to 202,345 by January 2026, a gain of 11,943 in six months.

Every one of those queries costs money, too.▸ FMCSA guidance sets the Clearinghouse query fee at a flat $1.25 per query, charged to the employer (or its designated consortium/third-party administrator) for every pre-employment check and every mandatory annual check on drivers already on payroll. It's a small line item per query — but it's now also run by every state motor vehicle office in the country, every time a CDL comes up for renewal.

Figures are drawn from the FMCSA Drug and Alcohol Clearinghouse's own published monthly snapshots and reflect Clearinghouse-registered violations only; they do not capture drivers disqualified through other channels (state DUI convictions, medical decertification, etc.). The $9.1 billion and $11.6 billion figures are calculated by this publication — multiplying the cited driver counts by the BLS median wage for the occupation — and represent foregone earning potential in that job, not a government-reported loss total.
