All of the brave trucks have different duties. The fire truck puts out fires and the tow truck saves other vehicles. But the garbage truck just collects trash, but maybe he has super powers that only come out when it snows! I love the illustrations in this book. They are bright, bold, and clear. Each page has very little to focus on, so the trucks really become easy to point out. The text is simple as well. There are just a few words per page, and they are very cut and dry and easy for toddlers to understand and learn from.
