Vehicle entering intersection marked stop or yield

Except when traffic is being controlled by a police officer or a traffic-control signal: 1. When proper signs have been erected, the driver of a vehicle shall stop or yield at a clearly marked stop line or, if there is none, before entering the crosswalk on the near side of the intersection or, if there is none, then at the point nearest the intersection where the driver has a view of approaching traffic on the through highway. After having stopped or, in the event of a yield sign, slowed or stopped, the driver shall yield the right-of-way to other vehicles which have entered the intersection from such through highway or which are approaching so closely on such through highway as to constitute an immediate hazard during the time such driver is moving across or within the intersection. 2. The driver of a vehicle shall stop in obedience to a stop sign or yield in compliance with a yield sign, in compliance with the manner prescribed in subsection 1, prior to entering an intersection if a stop sign or a yield sign is erected at one or more entrances thereto although not a part of a through highway and shall proceed cautiously, yielding to vehicles not so obligated to stop or yield and which are within the intersection or approaching so closely as to constitute an immediate hazard during the time such driver is moving across or within the intersection.
