"Ohio is a traditional open carry state. Recently, the Ohio legislature passed HB-12 over Governor Taft's veto, thus preempting all local open carry bans even in Ohio's "home rule" localities. Unfortunately, despite passage of HB-12, a permit to conceal is still required to openly carry a handgun in a vehicle."
Non permit holders and all users of long guns have much stricter rules for carrying firearms in their vehicles. Ohio statute O.R.C. 2923.16 allows for three ways for those not licensed to carry a concealed firearm to transport firearms in a motor vehicle. The firearm(s) must be unloaded (by O.R.C. 2923.11 unloaded includes an empty clip) and carried in one of the following ways:
(1) In a closed package, box, or case;
(2) In a compartment that can be reached only by leaving the vehicle;
(3) In plain sight and secured in a rack or holder made for the purpose;
(4) If the firearm is at least twenty-four inches in overall length as measured from the muzzle to the part of the stock furthest from the muzzle and if the barrel is at least eighteen inches in length, either in plain sight with the action open or the weapon stripped, or, if the firearm is of a type on which the action will not stay open or which cannot easily be stripped, in plain sight.
