A spike trip is a device used to impede or stop the movement of automobiles by flattening their tires. Generally the strip is composed of collection of 1.5" to 3" long metal barbs pointing upward. The barbs are designed to puncture and flatten rubber automobile tires when an automobile is driven over them.
Spike strips are also used to control ingress and egress to certain areas where automobiles travel. A one-way spike strip will allow an automobile to travel over them in one direction. The spikes are hinged so that they collapse harmlessly when driven over in one direction, but remain upright when driven in another.
