prowl car

“Wait a minute. That’s Junior Palmer’s prowl car. He’s a deputy sheriff.”

Policing was "relaxed," at best, with two officers sitting in each prowl car and driving aimlessly around the streets.

Then the howling prowl cars converged on the scene.

Now they would be ringing in the stations of the Protection Police and call orders would go out to the radio-equipped prowl cars.

Even in the reflected lights of the prowl car's head lamps, the muzzle looked only slightly smaller than the entrance to Mammoth Cave.
