More than 202,000 commercial driver's license holders are currently in prohibited status and unable to legally operate a commercial motor vehicle under the FMCSA Drug and Alcohol Clearinghouse as of January 2, 2026, with 159,226 of them having taken no steps toward the return-to-duty process, according to FreightWaves. Marijuana accounts for approximately 59 to 60 percent of all positive drug test violations in the database, and a separate FMCSA rule effective March 16 is simultaneously phasing out eligibility for an estimated 194,000 nondomiciled CDL holders.
Operator takeaway
Query the Clearinghouse before every hire and annually for every current driver — a missed query averages $5,600 in penalties per violation, and your applicant pool is substantially smaller than surface-level credentials suggest.
