Dolly (trailer)

A dolly is like a super strong cart with wheels that can help a big truck move an extra heavy load. It’s like when you help Mom and Dad push the grocery cart and you can put more groceries in it because it’s easier to push with the wheels. The dolly’s job is to take the weight of the heavy load so that the truck doesn’t have to carry it all by itself. It’s like having a helpful friend to share the weight with you! The dolly also helps the truck make really tight turns, just like you can turn the grocery cart easily in the store. This means that the truck can go to lots of different places and deliver lots of different things, all thanks to the dolly’s help!
