They're big. They're tough. And when rocks, sand, gravel, or dirt need moving, they're the perfect truck for the job! In this book, readers will discover all about dump trucks and the men and women who drive them. Learn about the machinery and technology that allows these trucks to deliver and tip tons of rocky materials. Discover how dump trucks are able to travel over rough, bumpy terrain thanks to their super-strong, giant tires. Join a dump truck driver as they visit a quarry to collect materials and then deliver them to a construction site. And see dump trucks working in partnership with diggers to remove huge quantities of soil from an area of land where a new freeway is being constructed. Filled with photos, this book is a fascinating read for all truck fans and young readers who prefer factual books. It's also perfect for supporting social studies topics such as "The Jobs People Do" and "People in Our Communities Who Help Us."
