PIT is an
acronym meaning Pursuit Intervention Technique (Yes, I know the phrase "Technique Maneuver" is somewhat redundant, but the
police and
reporters use it).
The PIT maneuver is a technique used by some law enforcement organizations to put an early end to pursuits, particularly high speed pursuits. It involves steering the front end of a police car into the side of a fleeing car, causing it to spin out. It can only be safely used at relatively low speeds (35 MPH and lower, generally). It can be defended against by a skilled driver, but there are very few people who would be fleeing from the police who have both the skill and the knowledge to counteract it.
Here in California, the California Highway Patrol uses it whenever the situations are favorable, and the LAPD has been known to employ it occasionally.
