This substitution of copy may be made without the issuance of any additional permit by a local government agency. The purpose of this provision is to prevent any inadvertent favoring of commercial speech over noncommercial speech, or the favoring of any particular noncommercial message over any other noncommercial message. This provision prevails over any more specific provision in this regulation to the contrary.".
