Across the UK, events of every scale bring communities together from food festivals, concerts and charity runs to marathons, parades and cultural celebrations. With increased footfall comes an increased responsibility to protect attendees from accidental or deliberate vehicle movements. Crowdguard provides temporary HVM and vehicle security barrier solutions that keep people safe while ensuring events remain open, accessible and enjoyable.
We take a calm, proportionate approach grounded in national guidance from NPSA and PSSA. Our specialists work closely with event organisers, Safety Advisory Groups (SAGs), local authorities, police and Traffic Management (TM) partners to design temporary HVM schemes that are informed by risk, operational needs and the unique characteristics of each location.
Whether you’re planning a city-centre celebration, a local community fair or a major event attracting tens of thousands of people, Crowdguard delivers trusted, flexible and fully compliant protection that reduces risk without impacting the visitor experience.
Understanding Vehicle-Related Risk at Events
Every event environment is different, but several common factors influence the need for temporary HVM:
Proximity to Live Roads
Predictable Crowding
Lack of Natural Standoff
Ingress and egress peaks, queueing areas and vendor zones naturally concentrate people in specific locations.
Many events take place adjacent to vehicle routes or within town-centre spaces where vehicles could reach crowds without intervention.
Open squares, wide pavements or temporary event footprints often provide little separation between pedestrians and vehicles.
Accidental Vehicle Incursion Risk
Even without malicious intent, driver error or confusion can pose a risk in mixed-use environments.
Crowdguard’s role is to help organisers understand these factors through proportionate, real-world assessment preventing overspecification and ensuring planning decisions remain practical and justified.
PLAN
PLAN – Risk-led analysis for informed decisions
We begin with a threat, vulnerability and risk assessment (TVRA), and where appropriate, a vehicle dynamics assessment (VDA). This identifies realistic vulnerabilities, crowd movement patterns and operational constraints.
We never overstate risk our goal is clarity, not complexity.
PROVIDE
PROVIDE – A tailored HVM specification
Using insights from the PLAN stage, we design a temporary HVM scheme aligned with NPSA guidance and the needs of your event. This may include:
- temporary HVM
- vehicle security barriers
- pedestrian-permeable solutions
- access-controlled openings for emergency vehicles
- branding opportunities or wayfinding
Our design always prioritises practicality, permeability and proportionate protection.
PROTECT
PROTECT – Professional deployment and on-site support
Our trained technicians install temporary HVM systems strictly “as tested,” ensuring every deployment aligns with certified configurations and approved specifications. We complete thorough pre-event checks to confirm the scheme is safe, compliant and operationally ready.
After the event, we manage efficient de-rig, providing documentation and post-event reporting where required to support accountability and continuous improvement.
