If there is no sidewalk, where should pedestrians walk?

When there is no sidewalk available, pedestrians should walk facing oncoming traffic. This practice allows pedestrians to be aware of approaching vehicles, enhancing their safety by enabling them to see traffic coming towards them and take necessary precautions. Walking against the flow of traffic creates a natural line of sight that is important for both the pedestrian's awareness and the drivers' visibility, which can reduce the likelihood of accidents.

In situations where pedestrians walk with traffic, they may not be able to see vehicles approaching from behind, which can increase the risk of accidents. The other options, such as walking in the street center or purely on the shoulder, do not provide the same level of safety as facing oncoming traffic does. The guidance to walk facing traffic is a standard practice aimed at minimizing risks for pedestrians when sidewalks are not available.
