Federal law does not restrict individuals from transporting legally acquired firearms across state lines for lawful purposes except those explicitly prohibited by federal law to include convicted felons; persons under indictment for felonies; adjudicated “mental defectives” or those who have been involuntarily committed to mental institutions; illegal drug users; illegal aliens and most non-immigrant aliens; dishonorably discharged veterans; those who have renounced their U.S. citizenship; fugitives from justice; persons convicted of misdemeanor crimes of domestic violence; and persons subject to certain domestic violence restraining orders. Therefore, no federal permit is required (or available) for the interstate transportation of firearms.
Many states and localities have laws governing the transportation of firearms. Travelers must be aware of these laws and comply with legal requirements in each jurisdiction. There is no uniform state transportation procedure for firearms. If in doubt, a traveler should carry firearms unloaded, locked in a case, and stored in an area (such as a trunk or attached toolbox) where they are inaccessible from a vehicle’s passenger compartment and not visible from outside the vehicle. Any ammunition should be stored in a separate locked container. Title 18 Part 1 Chapter 44 s926A
