Vehicle Disabling Device

Abstract

A portable device for slowing and disabling moving vehicles, which consists of a plurality of individual blocks carried on a portable mat. The blocks are coated with an adhesive that affixes the blocks to the tire treads of a vehicle rolling over the device. The weight of the blocks unbalances the vehicle tires and creates a severe vibration, which retards the vehicle speed without severely destabilizing the driver's control of the vehicle.

I claim: 
     
         1 . A device for slowing and disabling a vehicle comprising:
 a portable mat adapted to be deployed in a roadway; and   a plurality of individual blocks carried atop the mat, each block having a top surface coated with an adhesive, which adheres to the tire tread of the vehicle when the vehicle rolls over the device.   
     
     
         2 . The device of  claim 2  wherein the mat is a flat elongated substrate. 
     
     
         3 . The device of  claim 3  wherein the mat is adapted to be manually contorted between a compact stowed orientation and extended deployed orientation. 
     
     
         4 . The device of  claim 1  and a film overlying mat and covering the plurality of individual blocks carried thereon. 
     
     
         5 . The device of  claim 1  wherein each of the plurality of individual blocks has a top surface and a bottom surface, the area of the top surface is greater than the are of the bottom surface.
