Determining who is at fault in a crosswalk accident, you usually look toward a statute. Statutes in most states say that a pedestrian facing a green light can cross the street or the roadway, unless the green signal is a turn arrow, and they can do that as long as they remain within any marked crosswalk, or if there are no marked crosswalks, they are still allowed to cross a street or roadway as long as they are facing a green light.
And all motor vehicles are required to yield the right-of-way to pedestrians that are lawfully within that intersection or crosswalk. If a light is yellow or red, a pedestrian is not supposed to enter a crosswalk or roadway unless, obviously, they have some other proper pedestrian crossing signal. If, for instance, you enter a crosswalk or roadway improperly, other vehicles/cars still have a responsibility to avoid hitting you, and so, there are statutes throughout the country that say, even when a pedestrian enters a crosswalk or tries to cross a street improperly, every driver should exercise due care to avoid colliding with them, and give some type of warning, if it’s possible, whether it’s beeping their horn or some other type of warning, if they have the ability to do that.
Ultimately, a driver of a motor vehicle tends to be in a better position to avoid an accident, and so, the law still places some responsibility on a driver to be able to stop if they can, or to be aware of their surroundings, and to take precautionary measures, if possible.
