In response to recent fatal accidents involving truck drivers, the US Transportation Department (DOT) has imposed new restrictions on commercial driver licenses (CDLs) for non-citizens. The emergency rules aim to address safety concerns and include a direct warning to California, which is facing potential funding cuts if it continues to issue licenses to undocumented immigrants. Approximately 194,000 non-domiciled CDL holders may be affected as the DOT seeks to enforce a crackdown on foreign drivers overstaying their visas. Critics are urging states to withdraw licenses from those who do not meet the new eligibility requirements, emphasizing the need for better regulation in the trucking industry.
