Final answer:
When it becomes necessary to walk on a roadway, you should walk on the left side. Walking on the left side allows you to see and react to any vehicles approaching you, reducing the risk of accidents.
Step-by-step explanation:
When it becomes necessary to walk on a roadway, you should walk on the left side. This means that you should be walking on the side of the road opposite to the direction of oncoming traffic. Walking on the left side allows you to see and react to any vehicles approaching you, reducing the risk of accidents.
This practice is followed in many countries, including the United States. The reason for this is to ensure the safety of pedestrians, as well as drivers. When pedestrians walk on the left side, they have better visibility of approaching vehicles, and drivers have a better chance of seeing pedestrians and taking necessary precautions.
For example, if you are walking on a road without a sidewalk, you should walk on the left side of the road so that you are facing traffic. This way, you are able to see oncoming vehicles and move out of the way if necessary.
