Abstract: An entrapment snare, consisting of two small but heavy weights connected by a flexible cable covered with spikes, is designed to be launched from a pursuing law enforcement vehicle at one of the rear tires of a fleeing vehicle. One heavy weight is attached to each end of the flexible cable.

The middle of the cable hits the target tire at or near where the rubber meets the road and the cable goes into tension. Very quickly, the two ends of the cable attached to the projectile weights pull tightly into place in front of the target tire.
