Well if your working to be an Ohio instructor you need to study a lot harder. There is no specific signage they can have their 3 year old draw a no gun sign in crayon and hang it up and it is legal. The attorney generals sight only suggests the wording it is not mandatory. Signage The law does not say precisely what language must be on the sign. At a minimum, signs must be conspicuous and inform people that firearms and/ or concealed handguns are prohibited. However, the law suggests that the prohibited locations post a sign that substantially says the following: Unless otherwise authorized by law, pursuant to the Ohio Revised Code, no person shall knowingly possess, have under his control, convey, or attempt to convey a deadly handgun or dangerous ordnance onto these premises. 17 An example of a standard warning sign approved for use on state buildings appears below. If you see this sign, it means that you cannot bring your concealed handgun inside. Businesses and persons wishing to post such signs are strongly advised to consult their legal counsel for language, style, format, and placement. Concealed Carry by Law Enforcement Federal law (HR 218) permits active and retired law enforcement officers, under specific circumstances, to carry a concealed firearm. This publication does not address issues related to HR 218. If you are an active or retired law enforcement officer and have questions about HR 218, consult an attorney. Reciprocity Ohio has agreements with other states to recognize one another’s concealed handgun licenses. Consult the Attorney General’s website for the most recent list of agreements. Be aware the laws of the other state apply to you when you are in that state. Open Carry Ohio’s concealed carry laws do not regulate “open” carry of firearms. If you openly carry, use caution. The open carry of firearms is a legal activity in Ohio. The sign is available to download from the Attorney General’s website at www.OhioAttorneyGeneral.gov at no charge.
