In Pixar's Cars, what is Doc Hudson's official role in Radiator Springs?

In Pixar's Cars, Doc Hudson serves as Radiator Springs' judge and doctor.

Doc is one of the town's most respected residents, and his official responsibilities help explain why the community turns to him during Lightning McQueen's stay. He is also an experienced mechanic and the local medical authority, giving him several practical roles in the small desert town.

The character's deeper history is revealed later: Doc was once the Fabulous Hudson Hornet, a celebrated race car and three-time Piston Cup champion. A severe crash ended his racing career, and his disillusionment shaped his guarded attitude toward the sport.

Viewers sometimes remember Doc mainly as Lightning's mentor or as Radiator Springs' doctor. Those are both important aspects of his character, but the film specifically identifies his civic position as judge and doctor. His role as sheriff belongs to Sheriff, another town resident.
