   A.   Two-Way Streets: Except as otherwise provided in this chapter, every vehicle stopped or parked upon a two-way street shall be stopped or parked with the right hand wheels parallel to and within eighteen inches (18") of the right hand curb or as close as practicable to the right edge of the right hand shoulder.
   B.   One-Way Streets: Except when otherwise provided, every vehicle stopped or parked upon a one-way street shall be stopped or parked with the right hand wheels parallel to and within eighteen inches (18") of the right hand curb or as close as practicable to the right edge of the right hand shoulder, or with its left hand wheels within eighteen inches (18") of the left hand curb or as close as practicable to the left edge of the left hand shoulder.
   C.   Angular Parking:
      1.   Indicated With Markings: Except in such portions of the city as shall be marked for angular parking by lines upon the surface of the street, vehicles shall be parked within the same and at the angle shown thereby; provided, however, that where angular parking shall have been directed, no vehicle having an overall length in excess of twenty feet (20') shall be so parked. Where lines or markings designate parking spaces, vehicles shall be parked in accordance with those lines or markings, and it shall be unlawful to park any vehicle across any such lines or markings.
      2.   Federal Aid Or State Highways: The police department may permit angle parking on any street, except that angle parking shall not be permitted on any federal aid or state highway unless the state of Idaho transportation department (ITD) has determined that the roadway is of sufficient width to permit angle parking without interference with the free movement of traffic.
      3.   Backing Into Space Prohibited: Where angle parking is permitted, the vehicle shall not be backed into the parking space with the front of the vehicle facing the roadway. (1974 Code § 7-201)
