Bicycle riders may utilize the sidewalk except in downtown West Bend and downtown Barton. All three of these collisions occurred in a part of town where riding on the sidewalk is permitted. But bicycle riders on the sidewalk must stop at every intersection and must understand that they are less visible to drivers than they would be if they were on the street. This is nothing new. For their part, drivers must come to a full stop at a red light or stop sign before completing a right-hand turn and under all circumstances must yield to anyone in a crosswalk.
Infrastructure doesn’t fix this. Only better behavior fixes this. There will always be points of intersection between bikes, pedestrians and motor vehicles, and it’s up to you to conduct yourself safely at those points.
