I don't think the sign itself violates state law, after all it was just made by some guy--with regard to the firearms regulations, the sign does not carry the force of law in Utah...i.e you are not obliged to follow the warning as you would be in some states, like Texas, where a properly made sign does carry force of law and disobeying the sign itself breaks the law.
