What is the name of the police officer in Cars?

The police officer in Cars is Sheriff. He is Radiator Springs’ resident peacekeeper and is identified by the title “Sheriff,” which functions as his canonical character name.

Sheriff is not a human officer but an anthropomorphic 1949 Mercury Eight police car. He patrols Radiator Springs and takes local law enforcement seriously, even though the sleepy Route 66 town has little crime. His duties include pursuing Lightning McQueen after the race car tears through town and causes extensive damage.

Sheriff is voiced by Michael Wallis, a Route 66 historian whose real-world knowledge helped connect the character to the highway’s culture. That background is fitting because Radiator Springs is built around the decline and nostalgia of historic Route 66 communities.

Lizzie is an elderly town resident, Fillmore runs the local organic-fuel business, and Sarge is a military veteran. They are all prominent Radiator Springs characters, but only Sheriff serves as the town’s police officer.
