A tire-puncturing apparatus is disclosed which can be placed on a road surface in front of a moving vehicle such as an automobile. The apparatus has a collapsible outer cover which makes it safe to handle the apparatus before its use, yet being collapsible, does not impede the operation of the apparatus in puncturing the tires of the target moving vehicle. The apparatus also has a flexible interior cover made of rip-resistant material. A special three-piece spike is used to first penetrate the tire's surface and then embed a hollow quill in the tread of the tire such that the tire will deflate at a controlled rate, rather than causing a blowout and subsequent loss of control of the vehicle. The tire-puncturing apparatus is designed to be easily carried in the trunk of a police vehicle, and has an optional mating connector such that two or more of the tire-puncturing devices can be rigidly connected together to cover a larger portion of the road surface.
