Most often, the fault lies with the driver in pedestrian accidents. Some of the most common causes of pedestrian accidents include driving under the influence, driver impatience, recklessness, speeding, inclement weather, road construction, and vehicles making left turns.
If a pedestrian is at fault, typically it is due to jaywalking, not abiding by traffic control signals, walking while not facing traffic, or walking in the street instead of on the sidewalk.
