The States Helping Apprehend Rogue Exports Act would require states to share motor vehicle registration data with the federal government in order to receive certain transportation security grants. Specifically, states would need to enter into data sharing agreements with the Department of Homeland Security and the Department of Transportation that allow these agencies to request information about registered vehicles, including registration details, titles, and vehicle identification numbers. The bill applies this requirement to three federal grant programs: the Port Infrastructure Development Program, the Port Security Grant Program, and the Airport Improvement Program. States that refuse to sign such agreements would become ineligible for funding under these programs. The legislation does not establish new funding amounts or specific timelines for implementation beyond making data sharing a prerequisite for grant eligibility.
