Understanding Dump Trucks for 4-Year-Olds

A dump truck is a special kind of big truck! It helps move heavy things like rocks, sand, or dirt. First, a big truck drives to a place where it needs to pick up the heavy stuff. Then, it lifts up its back part, called the bed, to let everything fall out. Imagine a toy truck that can pour out its toys! That's what a dump truck does with the heavy stuff.

It's very handy for people who are building things, like houses or roads. So, next time you see a big truck on the road, you can remember it's a dump truck!
