ABSTRACT:
A vehicle barrier (20) includes an upper barrier member (22), a lower barrier member (24), and a plurality of linking members (28A,28B,30A,30B). The plurality of linking members extend between the upper and lower barrier members other than parallel to a median of the barrier, leaving one or more large gaps in the barrier effective so that a vehicle tire overriding the lower barrier member and any lower portion of any linking member will encounter such a gap and, thereby be unable to draw the barrier beneath the vehicle to drive over the barrier. The linking members may be disposed at angles between about thirty to about sixty degrees relative to the median as measured with the barrier in an unfurled condition. The vehicle barrier (20) may also include a median member (26) extending along the median of the barrier.
