1. A method of arresting a forward motion of a moving vehicle travelling on a surface with a vehicle barrier, the vehicle barrier comprising a base plate, a first post, a second post, and a beam, wherein the base plate is positioned on the surface and has a width extending laterally to define a vehicle passage between the first post and the second post and has a depth extending perpendicular to the width from a front edge of the base plate to a back edge of the base plate, and wherein the beam, when in a blocking position, is positioned proximate the back edge and extends across the vehicle passage from the first post to the second post, the method comprising:
contacting, with the beam in the blocking position, the moving vehicle with the beam, where the forward motion is in a direction from the front edge toward the back edge; and
rotating the base plate due to the contacting the moving vehicle with the beam causing the base plate to contact a frame of the vehicle:
wherein the second post comprises a J-slot formed in a face of the second post, the J-slot comprising a primary vertical slot extending from an open top end of the primary vertical slot in a top of the second post to a bottom end of the primary vertical slot and a horizontal slot extending from the bottom end toward the first post, the horizontal slot comprising a trap extending toward the top of the second post; and
wherein the beam comprises a first end pivotally attached to the first post and a second end comprising a pin disposed in the J-slot when the beam is in the blocking position.
