A security cover for an automatic gate arm protects against disengagement and removal of the gate arm for the purpose of unauthorized entry through the gate. The security cover comprises four walls and a top plate joined to form a housing that encloses a rotating turret and a portion of a drive arm used to actuate the gate. The security cover mounts over the turret using a vertical rod that extends from above the housing to a location within the drive mechanism of the gate arm motor, and a lock that secures the housing and prevents unauthorized tampering with the drive arm.
