The U.S. Department of Transportation, under the Trump administration, has issued a warning to California, Washington, and New Mexico, threatening to withhold millions in federal funding if these states fail to enforce English language proficiency requirements for truck drivers. Transportation Secretary Sean Duffy has emphasized the importance of these rules following concerns raised after a recent deadly incident involving a truck. The administration is giving the states a 30-day deadline to comply, and officials assert that stricter enforcement of English tests is necessary to ensure safety and communication standards in the trucking industry. The measures have sparked discussions, with some regions already taking steps to enhance their language requirements for commercial drivers.
