It is a book about children's favorite cars. Pictures using primary colors are clear and simple enough to catch the attention of children. There is a wiper to clean your favorite car, you need oil to drive, a light to shine brightly at night, a wiper to catch your vision when it rains, good traffic regulations, good traffic signs.

It is not a concept book that shows a kind of car but a brief introduction to how to use a car, what it takes to get a car rolling, what you need to keep while driving, and a very practical English expression in real life.
