North Carolina could lose nearly $50 million in federal funding if the state doesn’t revoke commercial driver’s licenses from immigrants who aren’t qualified to hold them after an audit uncovered problems, the U.S. Transportation Department said Thursday. The audit identified issues with more than half of the licenses reviewed, prompting the threat to withhold funding if corrective actions are not taken. This move is part of a larger federal crackdown aimed at ensuring only qualified drivers operate commercial vehicles. The federal review stems from past incidents, including a fatal crash in Florida involving an unqualified driver. North Carolina officials have yet to respond to the federal notification, but similar actions have been taken against other states like California and Pennsylvania, where thousands of licenses for immigrants have been flagged as invalid.
