What is sidewall?

A sidewall is like the edge of a road where you walk or ride your bike.

Imagine you're walking to school, and there's a path next to the street. That path, the one between the road and the grass or the buildings, is the sidewall. It’s like a little border that helps keep people safe while they’re walking or riding.

Sometimes, roads are just wide open with no borders. That’s fine for cars, but it can be tricky for walkers or bikers. A sidewall gives you space to move without getting in the way of cars. It's like having a little lane just for you and your friends on the way to school.

Some sidewalks are flat, like a smooth path you can run on. Others might have bumps or be made of bricks, it depends on where you live. But no matter how they look, sidewalls help people move safely and comfortably from one place to another.
