If you must walk on the highway, which side should you walk on?

When walking on a highway, it's essential for your safety to walk on the left side so you can see oncoming traffic. This allows you to be aware of vehicles approaching you and take any necessary action to ensure your safety. By facing oncoming traffic, you have the opportunity to react to vehicles more effectively. It also minimizes the risk of being surprised by a vehicle approaching from behind, which can be particularly dangerous.

Walking in the middle of the road, blending with traffic, or choosing any side based on preference does not prioritize safety and can lead to dangerous situations. It's crucial to always be cautious and alert while in or near traffic to prevent accidents.
