The Delinquent Road Hazards, also known as the Tuner Gang, are a group consisting of four troublemakers named Snot Rod, Boost, DJ, and Wingo. The Delinquent Road Hazards have caused trouble in many different installments of the Cars series, and are often portrayed as antagonists. Their logo is a typical graffiti drawing done with spray paint.
In Cars, the tuners are causing havoc on the highway when they come across Mack, a tired hauler that is transporting Lightning McQueen to the Los Angeles International Speedway. DJ plays music to cause Mack to fall asleep, while Boost and Wingo push him back and forth. Meanwhile, a bobblehead falls onto the trigger that opens the trailer, causing the back door to open. Snot Rod sneezes, which scares Mack, causing McQueen to fall out of his trailer. Towards the end of the film, they are caught speeding through Radiator Springs, and are impounded and sentenced to pull Bessie.
Cars: The Video Game
In Cars: The Video Game, they are hired by Chick Hicks to steal gear out of Lightning's trailer. To do so, DJ drives in front of Mack and plays music to put him to sleep, while Snot Rod holds a ramp behind Mack, so that Boost can jump onto the roof to open the trailer. Finally, Wingo collects five boxes of McQueen's gear, while avoiding other objects that fall out of the trailer. After McQueen hears the news, he immediately races out to the highway, and steals the gear back from them. They are then arrested by Sheriff, where they confess to being hired by Chick.
Cars: Radiator Springs Adventures
In Cars: Radiator Springs Adventures, the minigame Speed Trap has the four delinquents speeding along the highway, trying to escape from Sheriff (controlled by the player), who is attempting to catch them for speeding.

Cars 2: The Video Game
Cars: Fast as Lightning
