This bill amends Section 30103 of Title 49, United States Code, to establish that meeting applicable federal motor vehicle safety standards shall exempt manufacturers from common law liability for failing to exceed those standards. It specifically changes existing language to clarify this exemption, aiming to prevent common law suits from imposing requirements beyond federal regulations. The legislation's core purposes are to ensure the uniform application of motor vehicle safety standards promulgated by the National Highway Traffic Safety Administration (NHTSA) across all states. By doing so, it seeks to relieve what is described as an unreasonable burden on interstate commerce, which currently arises from common law suits that attempt to supplant these established federal safety standards.
