Big Rigs

Nothing hauls goods on cross-country highways like a big rig! This transportation book introduces beginning readers to the vehicles known variously as semi trucks, tractor-trailers, and 18-wheelers. Aided by eye-catching photographs, fun facts, and comic-inspired speech bubbles and humor, kids will learn about the design, functions, and working principles of these freight-carrying machines. A labeled diagram enhances comprehension. Includes a glossary, index, and further STEM resources.
