The NPSA (National Security Protective Authority) in the UK has provided guidance on various aspects of security, including mitigating the risk of vehicle attacks on infrastructure or crowded places. One such guidance is the Vehicle Security Barriers and Delay Standards.

The NPSA Vehicle Security Barriers and Delay Standards provide recommendations on the type of physical security measures that can be implemented to protect against vehicle-borne threats. These standards typically include guidelines on the selection, installation, and effectiveness of vehicle security barriers to delay and deter unauthorized or hostile vehicles from breaching critical infrastructure or high-risk areas.

Key components and considerations related to NPSA Vehicle Attack Delay Standards (VADS) may include:

1. Risk Assessment: Conducting a thorough risk assessment of the site or infrastructure to determine the level of threat posed by vehicle attacks and identify critical areas that require protection.
2. Selection of Security Barriers: Choosing appropriate vehicle security barriers based on factors such as the level of threat, site characteristics, the desired level of protection, and the need to balance security with operational requirements.

3. Installation and Configuration: Ensuring that security barriers are installed correctly and configured to provide the necessary level of delay and protection against vehicle attacks.
4. Delay Performance: Evaluating the delay performance of security barriers to ensure that they meet the specified standards and are effective in slowing down or stopping a hostile vehicle.
5. Integration with Other Security Measures: Coordinating the deployment of vehicle security barriers with other security measures, such as access controls, surveillance systems, and response protocols, to create a comprehensive security solution.

By adhering to the NPSA Vehicle Attack Delay Standards, organizations and infrastructure owners can enhance their resilience against potential vehicle-borne threats and reduce the risk of unauthorized vehicles causing harm or disruption to critical facilities or public spaces. These standards help organizations to implement proactive measures to safeguard their assets, personnel, and the general public from potential security incidents involving hostile vehicles.
