Piston Cup flagman
Dexter Hoover is a pick-up truck that serves as the flagman for the Piston Cup Racing series. He is a Pabloloco Compact Pick-Up that is painted blue and yellow, with the word "Official" paint on his hood and each of his doors, along with the Piston Cup logo. He has blue rims and a yellow bumper. His license plate reads A113CA.
In Cars, Dexter is first seen at the Motor Speedway of the South, waving his flags for the racers. He later appears at the Los Angeles International Speedway, waving the flags in the tie-breaker race.
Cars: Fast as Lightning
In Cars: Fast as Lightning, Dexter appears as a non-playable character that serves as the flagman on all 20 of the tracks, waving his flags to begin races.
Dexter also appeared in the comic, Wash Day.
"As a youngster Dex dreamed of being a real race car. A 4-cylinder compact pickup isn't exactly designed for the racetrack, but Dex found a way to put himself in the middle of his favorite sport. He climbed the ranks from selling pennant flags in the stands to top flagman on the circuit. His unorthodox caution flag pattern is a thing of beauty, and if it weren't for Dex, the races would never start -- and they'd never end."
- Dexter's license plate number, A113CA, is a reference to A113, the classroom in which several Pixar animators attended and also Mater's license plate.
- In Cars: Fast as Lightning, when the player passes the finish line, Dexter is waving a green flag, but in race cutscenes that immediately follow, he is waving a checkered flag.
