Jon Scieszka's Trucktown (Picture books)

Melvin, a cautious cement mixer, worries that he can't keep up with the other trucks, but when Rescue Rita needs to be rescued, he overcomes his worries and fears in order to help her.

This big, noisy, high-octane collection of favorite truckery rhymes includes "Peter Peter Payload Eater," "Little Dan Dumper," and "Pop Blows the Diesel."
