Hostile Vehicle Mitigation: Places, solutions and planning a strategy

For effective, secure and up-to-date perimeter security, it’s crucial to consider the ever-changing threat landscape. The rise of vehicle-borne attacks has made Hostile Vehicle Mitigation (HVM) measures an increasingly important part of physical security strategies.


Assessing the threat, designing a strategy

Vehicle-borne attacks can range from direct assaults, such as ramming, to a blast from a parked car using Vehicle-Borne Improvised Explosive Devices (VBIEDs). Such attacks have historically targeted busy pedestrian thoroughfares or open spaces for maximum impact.

A comprehensive HVM solution incorporates access control, to prevent unauthorised vehicles reaching their intended target area, and barriers, to impede or delay a hostile vehicle’s progress, whilst also allowing for flowing pedestrian movement and considering the aesthetic impact of barriers in the streetscape.

When establishing a robust HVM strategy for your site, there are several options to consider:

  • Traffic calming measures to slow, and more effectively manage, approaching vehicles
  • How new HVM measures will integrate with existing security features, for example fencing, access control gates, CCTV and/or bollards
  • Managing traffic, authorising legitimate vehicles and monitoring access to and from your site

To strengthen and modify perimeter security for your site based on your needs and the potential threats present, bollards, barriers, road blockers, access control and security fencing are among the most effective ways to impede an attack and limit the damage it may cause.

Vehicle Security Barriers (VSB)

There are two types of VSB: active VSBs include retractable bollards and road blockers, and rising, folding, sliding or swinging gates, and passive VSBs, such as fixed bollards, planter units, structural walls or enhanced fences, strengthened street furniture and earthworks, e.g. steps or ditches.

Vehicle Access Control (VSB)

Vehicle Access Control Points (VACPs) allow you to monitor and restrict vehicle access both to and from a site or public space and are typically designed in tandem with perimeter security and/or static VSBs to prevent circumvention.

As VACPs are often unmanned, it’s essential to consider routes for vulnerable road users, activation methods and unauthorised vehicle rejection as well as basic signs, instructions, signals and maintenance.



When specifying vehicle security barriers, it’s essential to understand the different capabilities of security products in order to incorporate the appropriate level of strength and resistance into your perimeter security strategy.

The British Standards Institution’s (BSI) PAS 68 rating is considered the benchmark for HVM products, offering a strength classification based on product performance when subjected to a single horizontal impact.

At Jacksons we offer a range of PAS 68 barriers, fencing and bollards, designed with the sole intention of preventing or minimising the damage inflicted by vehicle-borne attacks and capable of halting a HGV whilst remaining unobtrusive.

We also offer thorough site assessments, giving full consideration to the needs of any site, from stadiums and public spaces to utility sites and shopping centres, to ensure a comprehensive security solution. For more information about our PAS 68 solutions, click here.
