It shall be unlawful for any person, except persons permitted by law, to have or carry any shotgun, rifle, or air gun in or on any vehicle, unless such shotgun, rifle, or air gun is dismantled to render it incapable of being fired or is unloaded when enclosed in a case; the removal of the bolt from a bolt action rifle shall not be construed as dismantled so as to render it incapable of firing. (1974 Code)
