It is unlawful for any person, except a person authorized by law or by the division, to possess or have under his control any firearm, other than a pistol or revolver, in or on any motor vehicle unless the chamber of such firearm is unloaded. Any person in possession or in control of a rifle or shotgun in a motor vehicle shall allow any peace officer, as defined in section 33-1-102 (32), who is empowered and acting under the authority granted in section 33-6-101 to enforce articles 1 to 6 of this title to inspect the chamber of any rifle or shotgun in the motor vehicle. For the purposes of this section, a "muzzle-loader" shall be considered unloaded if it is not primed, and, for such purpose, "primed" means having a percussion cap on the nipple or flint in the striker and powder in the flash pan. Any person who violates this section is guilty of a misdemeanor and, upon conviction thereof, shall be punished by a fine of fifty dollars and an assessment of fifteen license suspension points.
