The Interstate Transport Act of 2025 aims to establish a federal right for law-abiding citizens to transport knives across state lines, preempting conflicting local and state prohibitions. This legislation permits individuals to transport knives for any lawful purpose from a place where possession is legal to another such place, provided they are not otherwise federally prohibited from possessing a knife. For transport by motor vehicle, knives must either be inaccessible from the passenger compartment or contained in a locked container if no separate compartment exists; for other modes, a locked container is required. The bill specifically allows for the carriage of certain emergency escape knives , designed for cutting safety belts, in passenger compartments without being locked, but excludes all knives from passenger aircraft cabins. Individuals complying with these provisions are protected from arrest under state or local knife laws. If a person successfully asserts this federal right in court, they are entitled to recover legal costs and attorney's fees, and in criminal proceedings, a prevailing party will also have their arrest and related criminal records expunged. This Act does not, however, limit any existing state rights regarding knife possession or transport.
