Establishes reasonableness standard for persons lawfully transporting firearm who deviate from course of travel.

This bill changes the standard for lawful firearm transporters who deviate from their course of travel from "reasonably necessary" to "reasonable." It specifically allows for common, brief, lawful detours like picking up passengers, obtaining supplies or medication, and using restrooms before reaching a permitted destination. The bill also explicitly permits firearm transportation during bona fide emergencies or declared disaster evacuations. This affects individuals lawfully transporting firearms under existing exemptions, such as gun owners traveling between home and business, hunters, and members of rifle/pistol clubs.
