A spike strip, 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 pointing upward. The barbs are designed to puncture and flatten tires when a vehicle is driven over them
Spike strips are also used to control access by vehicles. A one-way spike strip will allow a vehicle to travel over it in one direction; the spikes are hinged so that they collapse harmlessly when driven over in one direction, but remain upright when driven in the other.
A light-weight variant used by various police forces is the Stinger. It is manufactured in the United States by Federal Signal Corporation, although it is most well known for its use by British police forces. In the UK it is officially known as HOSTYDS (HOllow-Spike TYre Deflation System). It is designed to be easy to deploy, to puncture all four tires on the pursued vehicle, and to leave no debris which could affect following vehicles. It is packaged in a concertina form, with a tough frame of nylon strips holding pointed steel tubes. In use it is spread out across a surface or even thrown towards approaching vehicles, spreading out during flight. An attached rope makes it easy to regather after use before pursuing vehicles also run over it. The construction of the strip points the spikes into the tires as they pass over, and the spikes then detach and remain in the tires, their hollow construction assisting in the venting of air over 10 to 20 seconds.
Homemade spike strips, cheaply constructed using a steel pipe and common household nails, were banned in Australia in 2003 after being used against a police vehicle. Member of the New South Wales Legislative Assembly (presently holding the seat of Ryde) John Watkins, stated they would be added to the New South Wales prohibited weapons list [1].
