The purpose of the Non-Domiciled CDL Integrity Act is to establish clear requirements for states when issuing commercial driver's licenses (CDLs) to individuals who are not residents of the state. This legislation aims to ensure that only qualified individuals, particularly those with lawful immigration status or U.S. citizenship, can obtain these licenses, thereby enhancing safety and accountability in the commercial driving sector. Key provisions of the Act include specific criteria that states must follow when issuing CDLs to non-domiciled individuals.
