Claim 8:
9. 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, wherein the second post comprises a slot formed in a face of the second post, the 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, and wherein the beam comprises a first end attached to the first post and a second end comprising a pin, the method comprising:
pivoting the beam to a blocking position with the pin located in the primary vertical slot;
contacting, with the beam in the blocking position, the moving vehicle with the beam;
moving the pin into the horizontal slot in response to the contacting the moving vehicle with the beam; and
rotating the base plate in response to the contacting the moving vehicle with the beam causing the base plate to contact a frame of the vehicle.
