Bus drivers have blind spots to their right and rear. Passing on the right could get you squeezed against the curb if the bus pulls over. Be prepared to stop for pedestrians who may cross the street in front of the bus. Bicycling on sidewalks is permitted. In some areas local ordinances may prohibit sidewalk riding in commercial districts.
Pedestrians always have the right of way on sidewalks and in crosswalks.
Give an audible warning before passing pedestrians, and pass with care. Watch for cars crossing the sidewalk at driveways, alleys and intersections. Buildings, fences, poles, trees, shrubs, and parked cars can hide you from traffic and make it difficult for you to see them, too. At intersections, you have the same responsibilities as pedestrians. Stop and scan for traffic before entering the street from a driveway, alley or sidewalk.
