When walking on a road, it is important to use a sidewalk as far as possible. When there is no sidewalk, you should still stick to the side of the road without disrupting the traffic flow and walk in the opposite direction of the flow so you face the oncoming traffic. This is important because walking in the direction of the traffic flow restricts the awareness of the traffic to just your ears and can lead to accidents. Walking facing the traffic is safer as you can see the vehicles approaching you and protect yourself as and when required.
