Most police chases end when the car being pursued stops. This could be the result of a driver coming to one's senses, an erratic move resulting in a single car accident, or it could be the result of a police blockade with spikes or a PIT maneuver. The last is an example of one technique police departments employ to end police chases more safely. http://en.wikipedia.org/wiki/PIT_maneuver http://en.wikipedia.org/wiki/PIT_maneuver
