Abstract: A vehicle security gate apparatus and methods are provided for inhibiting undesired access to a protected area. The vehicle security gate apparatus preferably has a barricade adapted to be positioned adjacent a roadway to thereby block vehicle passage along the roadway into an area desired to be protected. The apparatus also preferably has a barricade rotating mount connected to the barricade for rotating the barricade about a predetermined axis so that the barricade rotates about the predetermined axis between a vehicle passage position which allows a desired vehicle to readily pass along the roadway into the protected area, a vehicle blocking position which blocks the roadway so as to inhibit an undesired vehicle from readily entering into the protected area, and a vehicle arresting position which arrests an undesired vehicle responsive to an attempt by the undesired vehicle to ram the barricade when the barricade is positioned in the vehicle blocking position.
