Final answer:
A pedestrian walking at night should walk against the traffic, facing oncoming vehicles for increased safety and visibility.
Step-by-step explanation:
If you are a pedestrian walking along the side of the road at night, the safest practice is to walk against the traffic. This means you should be facing oncoming vehicles, giving you the ability to see them and react if necessary. This practice increases your visibility to drivers and allows for better anticipation of potential hazards on the road. It's also important to stay as far to the side as possible, preferably on a sidewalk if available. Remember, your safety as a pedestrian is paramount, especially at night when visibility is reduced.
