Montana Title 61. Motor Vehicles § 61-8-355. Additional parking regulations

(1) Except as otherwise provided in this section, a vehicle that is stopped or parked on a two-way roadway must be stopped or parked with the right-hand wheels of the vehicle parallel to and within 18 inches of the right-hand curb or as close as practicable to the right edge of the right-hand shoulder.

(2) Except when otherwise provided by the authority having jurisdiction, a vehicle that is stopped or parked on a one-way roadway must be stopped or parked parallel to the curb or edge of the roadway in the direction of authorized traffic movement, with its right-hand wheels within 18 inches 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 18 inches of the left-hand curb or as close as practicable to the left edge of the left-hand shoulder.

(3) A local authority may by ordinance permit angle parking on a roadway, except that angle parking may not be permitted on any commission-designated highway system or state highway, as defined in 60-1-103, unless the department of transportation determines that the roadway is of sufficient width to permit angle parking without interfering with the free movement of traffic.

(4) The authority having jurisdiction may place official traffic control devices prohibiting or restricting the stopping, standing, or parking of vehicles on a highway where in its judgment this stopping, standing, or parking is dangerous to those using the highway or where the stopping, standing, or parking of vehicles would unduly interfere with the free movement of traffic.
