Whenever any roadway has been divided into two or more clearly marked lanes for traffic the following rules in addition to all others consistent herewith shall apply.
(A) A vehicle shall be driven as nearly as practicable entirely within a single lane and shall not be moved from such lane until the driver has first ascertained that such movement can be made with safety.
(B) Upon a roadway which is divided into three lanes and provides for two-way movement of traffic, a vehicle shall not be driven in the center lane, except when overtaking and passing another vehicle traveling in the same direction when such center lane is clear of traffic within a safe distance, or in preparation for making a left turn, or where such center lane is at the time allocated exclusively to traffic moving in the same direction that the vehicle is proceeding and such allocation is designated by official traffic control devices.
(C) Official traffic control devices may be erected directing specific traffic to use a designated lane or designating those lanes to be used by traffic moving in a particular direction regardless of the center of the roadway and drivers of vehicles shall obey the directions of every such sign. On multilane controlled access highways with three or more lanes in one direction, the city may designate lanes of traffic to be used by different types of motor vehicles.
(D) Official traffic control devices may be installed prohibiting the changing of lanes on sections of roadway and drivers of vehicles shall obey the directions of every such device.
(E) Vehicles shall be driven on a roadway, and shall only be driven on the shoulder for the purpose of stopping or accelerating from a stop while merging into traffic. It shall be a violation of this section if while merging into traffic and while on the shoulder, the vehicle passes any other vehicle on the roadway adjacent to it.
(F) This section shall not apply to any authorized emergency vehicle, to any authorized transit bus, to any farm tractor or implement of husbandry, to any service vehicle while engaged in maintenance of the highway or related work, or to any authorized vehicle within a designated construction zone.
