The present invention proposes a system and method for preventing a vehicle from rolling over in curved lane. An image corresponding to the lesion is obtained from each beam direction, and the beam shape and image are fixed to a common coordinate system to facilitate alignment. A threaded lock stud having a tapered external wall is constructed to fit at least partially within the hollow lock bolt and threadingly engage the threaded aperture of the housing and engage the tapered wall of the hollow lock bolt.
