What is Mater's job in Pixar's Cars?

Mater is a tow truck in Pixar's Cars.

Mater is Lightning McQueen's first close friend in Radiator Springs. He is rusty, cheerful, and proudly describes himself as the town's best tow truck. His job leads to the nighttime tractor-tipping adventure that becomes one of the film's most recognizable comic scenes.

Mater's full name is commonly given as Tow Mater, a pun on the phrase “tomater,” while his design resembles an old International Harvester boom truck. Larry the Cable Guy provides his voice in the feature films.

Mater is not a race car or a mechanic, although he helps friends with practical tasks. His role expands in Cars 2, where he becomes involved in an international spy adventure.
