“If they were walking i would have time to pass through without issue.”
Whether you have time/space to pass through is not relevant. If you are in a car and the pedestrian or cyclist is crossing the street, Washington State law requires the car driver to stop for the pedestrian or cyclist.
Also note that *all* intersections without marked crosswalks in Washington State are considered unmarked crosswalks. Automobile drivers are required to stop and let the pedestrian or cyclist proceed.
