Introduction
Hostile vehicles can pose multiple security challenges and have been used time and again for various attacks at public areas, high-security government establishments, hotels, and military facilities. Choosing the right type of solution, whether crash-rated bollards or road blockers, anti-ram barriers, or tire killers, can play a crucial role in improving property perimeter security, controlling vehicle entry and exit movements, and curtailing any attack using vehicles.
However, all solutions are designed to serve a certain prime purpose.
The right bollard solution depends on various factors, like the following:
- Threat level
- Property type
- Vehicle movement
- Security requirements
- Crash Rating requirements
- Access control integration
Let’s first understand various types of bollards and vehicle security systems.
1. Hydraulic Crash-Rated Bollards
Hydraulic bollards are retractable security bollards designed to stop unauthorized vehicle movements while allowing controlled vehicle access. They can be automatically lowered for authorized vehicles' access and rise again to secure the entry access.
2. Fixed Crash-Rated Bollards
Fixed bollards provide permanent perimeter protection in areas where vehicle movement is not allowed. The bollards remain permanent and require very little maintenance.
3. Hydraulic Road Blockers
Hydraulic road blockers are heavy-duty rising wedge barriers designed for high-security vehicle access points. They provide wider lane protection and higher stopping power with a single road blocker compared to bollards.
4. Tyre Killers
Tyre killers are vehicle control systems designed to stop vehicles moving in unauthorized directions and flatten the tyre if any attempts to bypass the secured areas.
5. Rapid Deployment Anti-Ram Barriers
Rapid deployment anti-ram barriers are temporary security barriers designed for fast installation without major civil work. They are used for temporary perimeter protection and emergency vehicle restriction and are popular for public events and gatherings.
How to Choose the Right Bollard, Road Blocker, Anti-Ram Barrier or Tyre Killer
Before selecting the right solution it is important to understand the property’s threat level, operational requirements, vehicle movement, and crash resistance needs.
Understanding Threat Levels and Recommended Security Solutions
Low Threat Environment
| Property Type | Primary Concern | Vehicle Movement | Crash Resistance Required | Recommended Solution |
|---|---|---|---|---|
| Commercial office buildings | Unauthorized vehicle entry | Low | Low | Fixed stainless steel bollards |
| Hotels | Pedestrian safety | Moderate | Low | Hydraulic bollards |
| Public plazas | Vehicle intrusion prevention | Low | Low | Surface mount bollards |
| Retail storefronts | Ram-raids | Low | Medium | Fixed crash-rated bollards |
| Educational campuses | Traffic management | Moderate | Low | Fixed perimeter bollards |
Medium Threat Environment
| Property Type | Primary Concern | Vehicle Movement | Crash Resistance Required | Recommended Solution |
|---|---|---|---|---|
| Warehouses | Controlled vehicle access | Medium | Medium | Hydraulic bollards |
| Industrial facilities | Unauthorized vehicle entry | Medium | Medium | Hydraulic bollards with access control |
| Logistics centres | Wrong-way entry prevention | High | Medium | Tyre killers |
| Utility facilities | Controlled perimeter access | Medium | Medium | Automatic hydraulic bollards |
| Gated communities | Access management | Moderate | Low | Access-controlled bollards |
High Threat Environment
| Property Type | Primary Concern | Vehicle Movement | Crash Resistance Required | Recommended Solution |
|---|---|---|---|---|
| Airports | Hostile vehicle mitigation | Controlled high-frequency access | High | PAS68 hydraulic Bollards or Road Blockers |
| Government facilities | Forced vehicle entry | Medium | Very High | PAS68 hydraulic Bollards or Road Blockers |
| Military sites | Vehicle-borne threats | Controlled access | Very High | PAS68/K12 Crash-rated Road Blockers |
| Data centres | Critical infrastructure protection | Controlled access | Very High | K4/K8 Crash-Rated Road Blockers or Bollards |
| Oil & gas facilities | High-speed vehicle impact protection | Medium | Very High | Crash-rated hydraulic bollards/road blockers |
Understanding Crash Ratings and PAS68
Crash ratings measure how effectively a security barrier can stop a vehicle impact.
K-Ratings
| Crash Rating | Vehicle Speed | Equivalent ASTM Rating | Security Level |
|---|---|---|---|
| K4 | 30 mph / 48 km/h | ASTM M30 | Medium Security |
| K8 | 40 mph / 64 km/h | ASTM M40 | High Security |
| K12 | 50 mph / 80 km/h | ASTM M50 | Maximum Security |
Higher crash ratings provide stronger vehicle impact resistance.
What Is PAS68?
PAS68 is an internationally recognized crash-testing standard for hostile vehicle mitigation systems. Unlike older K-ratings, PAS68 testing evaluates:
- Vehicle type
- Vehicle weight
- Speed
- Penetration distance
- Impact angle
This provides a more detailed understanding of real-world barrier performance. Vantage offers PAS68-rated hydraulic bollards and crash-rated road blockers for high-security applications.
Real-Life Implementation Examples
Government Utility Facility – Oman
A government water and electricity company in Oman installed 10 units of Vantage hydraulic automatic stainless steel bollards to prevent unauthorized vehicle access and improve hostile vehicle protection.
Why hydraulic bollards were chosen:
- Controlled authorized access
- High-security perimeter protection
- Outdoor reliability
- Premium appearance
Hydraulic Bollards – NAMA Water Oman
Government Data Centre
Vantage PAS68-rated hydraulic road blockers were installed at a government data center to secure high-security vehicle entry lanes.
Why road blockers were selected:
- Maximum hostile vehicle mitigation
- Full lane protection
- Centralized software to remotely control all blockers

NEOM, Saudi Arabia
Hydraulic PAS68-rated road blockers were deployed across entry and exit points at a high-security government facility in NEOM.
The project required:
- Continuous high-security operation and hostile vehicle mitigation
- Controlled access management
- Integration with wider perimeter security systems
Integration With Security and Access Control Systems
Modern bollards and road blockers are usually integrated with wider security infrastructure.
Common integrations include:
- RFID readers
- ANPR cameras
- Access control systems
- Traffic lights
- Loop detectors
- Fire alarm systems
- Software-based management from Central command rooms
For example:
- Authorized vehicles can automatically lower bollards using RFID or ANPR.
- Traffic lights indicate when vehicles can pass.
- Fire alarm integration can automatically lower barriers during emergency evacuation.
Vantage security also supports remote management and central monitoring for hydraulic bollards and road blockers.
Conclusion
There is no single perimeter security solution suitable for every property.
The right system depends on:
- Threat level
- Security objectives
- Vehicle movement
- Access frequency
- Crash resistance requirements
- Operational needs
For commercial properties, fixed bollards and controlled access systems often provide the right balance between security, appearance, and operational flexibility.
For airports, government facilities, military sites, and critical infrastructure projects, crash-rated hydraulic bollards and road blockers provide stronger hostile vehicle mitigation and perimeter protection.
Before selecting any perimeter security system, organizations should evaluate both current operational requirements and future security risks.
