Crimes: firearms; transporting or possessing a firearm in or upon motor vehicle; modify. Amends sec. 227d of 1931 PA 328 (MCL 750.227d).

HB 5164 modifies Michigan law to regulate transporting firearms and certain air guns in moving vehicles. It prohibits carrying a firearm (other than a pistol) or a pneumatic gun expelling metal BBs/pellets over .177 caliber in a moving vehicle unless the weapon is unloaded and stored in one of four ways: disassembled, in a case, in the trunk, or inaccessible from inside the vehicle. Violating this would be a misdemeanor punishable by up to 90 days in jail or a $100 fine. The bill directly affects drivers transporting these items in vehicles while operating them, with no exception for pistols.
