What is "if there is no sidewalk?

When there is no sidewalk available, pedestrians are advised to walk facing traffic so they can see oncoming vehicles and have the opportunity to react. It is recommended that pedestrians stay as far to the side of the road as possible to avoid being hit by passing vehicles. Additionally, it is important for pedestrians to wear bright or reflective clothing, especially in low light conditions, to increase their visibility to drivers. In some cases, it may be necessary for pedestrians to find an alternate route or use extra caution when walking in areas without sidewalks.
