If a highway is protected by a "STOP" sign, it is the duty of the driver approaching the highway from an intersecting highway, [unless otherwise directed to proceed by a police officer or traffic control signal,] to stop [before entering the crosswalk on the near side of the intersection] [at a clearly marked stop line] [at the point nearest the intersecting roadway where the driver has a view of approaching traffic on the intersecting roadway] and to yield the right-of-way to any pedestrian legally crossing the driver's roadway, and to any vehicle in the intersection or approaching on another highway so closely as to constitute an immediate hazard.

After stopping and looking both to the right and to the left, the driver, while exercising ordinary care, may proceed into the intersection. If a vehicle approaching on the protected highway is so near to the intersection as to constitute an apparent or immediate hazard, the driver of the yielding vehicle must wait until the other vehicle has passed. The driver of the yielding vehicle may enter the intersection only if a person of ordinary prudence would have had reasonable grounds to believe that the other vehicle was so distant from the intersection and proceeding at such a speed that one could safely proceed in advance of the other vehicle.
