A Stop Stick; i.e. a device consisting of a series of diagonally-spaced hollow spikes, placed face up on the surface of a road; used by law-enforcement agencies at roadblocks etc. to puncture the tires of a fugitive vehicle so as to bring it to a safe and gradual halt.
Setting up a roadblock just past the interchange, police used "sticky-stickies" to blow out the suspect's tires, and he was apprehended without incident about half a mile away.
