This triage tool is based on our expert knowledge and has been designed to provide you with an initial indication of whether you should consider hostile vehicle mitigation (HVM) for your premises, event or location. The tool has been designed to provide a rough indication of risk, based on the current proposals for Martyn’s Law. It is not a full risk assessment and it is intended only as a guide, to support you in deciding whether to take further advice. You can access free advice from the Protect UK website or your local Counter Terrorism Security Advisor (CTSA), or get in touch with our team for a full Threat, Vulnerability & Risk Assessment (TVRA).
