Reducing Your Risk is a series of lessons on mitigating crash risks. Regardless of who would be at fault, the bicyclist has a lot of power to prevent conflicts and crashes.
As we learned in the Pedestrian Rules section, drivers are required to yield to sidewalk traffic when entering and leaving a roadway. In practice, people are often distracted, overtasked or literally unable to see bicyclists on the sidewalk. A bicyclist who understands the risk factors and compensatory behaviors can choose to use a sidewalk, sidepath, or other parallel bike facility with relative safety.
