No person may stop, park, or leave standing a vehicle, whether attended or unattended, upon or within eight feet of a roadway, except where the roadway is of sufficient width and design to allow parking without interfering with the normal flow of traffic or with snow removal or other highway maintenance, and where the parking, stopping, or standing is not prohibited by an official traffic control device, unless directed to do so by an official flag person or police officer. (Ord. 13-06-332 § 4)
