ABSTRACT:
A sacrificial barrier for use along a highway, usually arranged in an array of such barriers for causing a relatively rapid deceleration and stopping of a vehicle to prevent substantial injury to the vehicle and the occupant thereof. The barrier comprises a container body, a new, improved frangible support table within the body and a quantity of a dispersible mass supported on the support table. One or more spacers may be used under the table for barriers designed to maintain a constant center of gravity when using smaller quantities of dispersible mass.
