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

Walking on the left side of the highway is the safest practice because it allows you to face oncoming traffic. This way, you can see vehicles approaching you and take necessary actions to avoid potential accidents. Being able to watch for oncoming vehicles gives you a chance to react timely, such as moving to the side or stepping off the road if a vehicle is too close.

Although there can be specific contexts where other options might seem plausible, such as walking only on the shoulder, the fundamental safety principle is to always walk against the flow of traffic. This is crucial for your visibility and allows both you and the drivers to be aware of each other's presence.
