Okay, little friend! Let's talk about big trucks!
Most trucks have something on top called a roof. The roof helps to keep things inside safe from the sun and rain. It’s like an umbrella but for trucks!
But guess what? There is a special kind of truck called a dumper truck that doesn't have a roof! Can you imagine that? This truck is built to carry really big things like dirt or rocks.
When a dumper truck gets to where it wants to take the big stuff, it can tip its back to drop everything out. It’s like when you tip over a big toy box and let all the toys fall out!
So, dumper trucks are super helpful even though they don’t have a roof, because they can deliver their really heavy loads easily!
