The U.S. Department of Transportation is withholding about $160 million in federal safety funding from California after the state missed a January 5 deadline to revoke more than 17,000 commercial driver’s licenses that were improperly issued to foreign drivers. The Federal Motor Carrier Safety Administration (FMCSA) determined the licenses did not comply with federal rules, citing expiration dates beyond drivers’ lawful U.S. presence. California had postponed the revocations, prompting this action. The FMCSA insists on strict compliance with safety regulations, while state officials argue they had been negotiating timelines.
