This bill proposes to withhold 50 percent of specific federal highway funds from states that do not comply with new requirements regarding driver's licenses and immigration information sharing, starting in fiscal year 2027. Its core purpose is to prevent states from issuing driver's licenses to individuals who lack proof of U.S. citizenship or lawful permanent residence. To achieve compliance, a state must enact a law prohibiting the issuance of any driver's license to individuals without such proof. Furthermore, states must not impede local or state government entities from sharing immigration enforcement information with the Department of Homeland Security. This information includes details about an individual's citizenship or immigration status and their release from detention facilities. The Secretaries of Transportation and Homeland Security are tasked with determining each state's compliance and maintaining a publicly accessible database of this status. This measure aims to ensure states align their policies with federal immigration enforcement efforts.
