Hostile vehicle mitigation

Hostile vehicle mitigation (HVM) is a generic term that covers a suite of anti-terrorist protective measures that are often employed around buildings or publicly accessible spaces/venues of particular significance. The design of these various vehicle security barriers and landscape treatments came about as security authorities across the globe sought to mitigate the effects of vehicle-borne improvised explosive devices (VBIED) and vehicle-ramming attacks.
