CA 2268643

A spiked road barrier is provided for deflating the tires of a fleeing vehicle. The barrier includes a housing arranged to be mounted within a trench in a roadway. A cover plate is mounted on a top side of the housing such that it is flush with a top side of the roadway. The cover plate includes a plurality of apertures therein, each for receiving a spike therethrough in an armed position. The spikes are mounted on a bar within the housing and extend upward through the apertures in the cover plate in the armed position. The bar may be lowered into an unarmed position such that the spikes do not extend upward past the cover plate using an actuator mounted within the housing. A membrane is coated over the top side of the cover plate to cover the apertures and seal them closed in the unarmed position. When the spiked road barrier is activated, the spikes are displaced upward and pierce through the membrane.
