One of the common yet lesser known tactics used by law enforcement to stop fleeing vehicles is a tactic known as Pursuit Intervention Technique, or PIT.
PIT was developed from the “bump-and-run” technique in stock car racing, in which a trailing vehicle bumps the rear of another vehicle slightly from the side, causing the tires to lose traction and forcing the driver to slow down or correct the direction of the vehicle.
As a police maneuver, PIT is designed to spin a vehicle around, thereby forcing it to come to a stop.
At high speeds, PIT can be extremely dangerous for both suspects and officers, thus it is usually only attempted at lower speeds. Most sheriff’s departments and highway patrols that use PIT have rules and regulations governing its use.
You can see a PIT stop in action from the 2017 arrest of 3 Portland murder suspects in this video.
