Refrigerator truck

Okay kiddo, have you ever seen a big truck that delivers food to the grocery store? Well, sometimes that food needs to be kept really cold or it will spoil and be yucky to eat. So, a refrigerator truck is a special kind of truck that has a big fridge inside of it to keep the food cold. Just like the fridge in your house keeps your juice and your snacks cold, but much bigger. The truck is like a big icebox on wheels! This way, the food stays fresh and people get to eat yummy things like fruits, vegetables, and meat. Isn't that cool?
