Spike strip

A spike strip (also known as traffic spikes, tiger teeth, alligator teeth, tire shredders, one-way traffic treadles, Cobra, Enforcer, Python, stinger, spike belt or stop stick, and formally known as a tire deflation device), is a device used to impede or stop the movement of wheeled vehicles by puncturing their tires. Generally, the strip is composed of a collection of 35 mm to 75 mm (1.5" to 3") long metal barbs, teeth, spikes pointing upward. The barbs are designed to puncture and flatten tires when a vehicle is driven over them. The barbs may be hollow or solid. Hollow barbs are designed to allow air to escape at a steady pace in an attempt to reduce the risk of the driver crashing into oncoming traffic or the surroundings.

According to a national law enforcement memorial organization in US, records show that since 1996 as many as 20 or more police officers in the United States have died on duty while manually deploying old-fashioned road spikes or similar manual tire-deflation devices. Remotely deployable spike strips have been developed to reduce the danger to police officers deploying them.

Homemade spike strips, cheaply constructed using a steel pipe and household nails, were banned in New South Wales in 2003 after being used against a police vehicle. John Watkins, a member of the New South Wales Legislative Assembly, stated they would be added to the New South Wales prohibited weapons list.
