ABSTRACT:
Previous devices for inhibiting the passage of pneumatically tired wheeled vehicles have been too heavy or bulky for quick deployment and easy transport. A portable easily assembled barrier is disclosed which has a number of planar cutters which have a base to engage a roadway and to orient the cutting surfaces. These cutters are spaced along an elongated rod by a number of distance pieces and the distance piece at each end can be used to connect one rod to another so that the assembly can span a roadway.
