If you are walking along a highway, always walk on the shoulder on the left side, facing traffic.

Explanation:

In city traffic people play various roles as citizens. When in a vehicle - whether it is a car, bus, motorcycle, or bicycle - they are drivers or passengers and must behave safely, driving carefully, wearing a helmet or seat belt in the front and rear seats. When walking, they are pedestrians and should also be responsible and careful in traffic.

When a pedestrian is walking down a road, he or she should always walk on the shoulder on left lane, facing traffic. This allows pedestrians to walk in the opposite direction to drivers, making it easier for drivers to see pedestrians and making it easier for pedestrians to view cars.
