The highway patrol car is a pre-War supercharged police car that was used by troopers of the Nevada and California highway patrol to protect the interstates.
These coupes have a rear-mounted high power engine, two doors and an aerodynamic shape. There are three variants, two for the Nevada Highway Patrol and one for the California Highway Patrol. Other than the seal, the cars are identical.
Highway patrol cars appear only in Fallout: New Vegas.
