When cars are present, where should pedestrians walk?

Pedestrians should walk on a sidewalk or shoulder to ensure their safety and visibility. Sidewalks are specifically designed for pedestrian use, providing a safe path away from vehicle traffic. If a sidewalk is not available, walking on the shoulder allows pedestrians to stay as far away from moving vehicles as possible, minimizing the risk of accidents.

The other options do not prioritize pedestrian safety. Walking in the middle of the road puts pedestrians at high risk of being struck by vehicles, while walking on either side of the road could still expose them to dangers from traffic, especially if visibility is low or vehicles are coming around a corner. It's crucial for pedestrians to utilize designated areas for walking to maintain safety.
