Vehicles are something we encounter every day, and they make our lives much easier. This book takes a close look at how they are built and how they function. What technical construction makes it possible to transport freight that weighs many tons? And what exactly is a PTO shaft? Young truck fans will get to know the big vehicles up close and personal, as well as the role they play in our lives.
