Okay, little one! Let’s talk about dumper trucks! They are big trucks that help carry things like sand or gravel. Imagine a big toy truck that can hold lots of stuff. These trucks have a special back part that can lift up!
When the truck lifts up, it lets the sand or gravel fall out. That’s why it doesn’t need a roof like other trucks. It can open up and dump everything on the ground. Isn’t that neat? So, we use dumper trucks to move sand or gravel without needing a cover on top!
