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). The sorts of places that warrant consideration as potential terrorist targets in need of HVM include: government buildings, airports, large railway stations, sports venues, concentrations of entertainment and crowded night time economy, etc.
