The federal government’s crackdown on commercial driver’s licenses for immigrants has found problems in eight states so far following several deadly crashes.

Transportation Secretary Sean Duffy has publicly threatened to withhold millions in federal funds from California, Pennsylvania, Minnesota, and now New York after investigations found issues such as licenses that remained valid even after an immigrant’s legal status had expired. The Department of Transportation has also sent letters detailing similar concerns to Texas, South Dakota, Colorado, and Washington during the recent government shutdown.

Concerns about immigrant truck drivers spiked after a tractor-trailer driver, not authorized to be in the U.S., caused a crash in Florida that killed three people. Following that, another deadly crash in California, involving an undocumented truck driver, intensified scrutiny.

Duffy proposed new restrictions in September aimed at limiting which noncitizens can obtain licenses for driving larger vehicles, although a court has temporarily paused these new rules.

States like California have faced specific scrutiny. Following Duffy's threats, California has revoked 21,000 commercial driver’s licenses after confirming issues with them, while Pennsylvania faces nearly $75 million in potential funding cuts if it cannot prove its licensing practices are sound.

New York is now under investigation for improperly issuing many of its commercial licenses, with federal officials claiming that many were issued without valid verification of the applicants' immigration statuses.

The findings across various states indicate systemic issues with how licenses were issued to noncitizen drivers, underlining the need for rigorous audits and regulatory compliance to ensure road safety and prevent further tragic incidents.
