Hydraulic Road Blocker vs Tyre Killer:
Vehicle Threat Mitigation at Its Best
Posted by Secure India | Updated: July 11, 2025
When it comes to hostile vehicle mitigation (HVM), both hydraulic road blockers and tyre killers serve distinct functions. Here's how they compare in terms of threat level resistance, installation, and usage.
What is a Hydraulic Road Blocker?
Hydraulic road blockers are crash-rated steel barriers that rise from the ground to physically stop vehicles. They are often tested to PAS68 or IWA14 standards and can stop vehicles traveling at high speeds.
What is a Tyre Killer?
Tyre killers consist of retractable metal spikes that puncture the tires of unauthorized vehicles. They act as a deterrent and slow down vehicles but may not completely stop high-speed intrusions.
Where Are They Used?
- Hydraulic Road Blockers: Embassies, military bases, nuclear plants
- Tyre Killers: Border checkpoints, jail entrances, toll plazas
Comparison Table
| Feature | Hydraulic Road Blocker | Tyre Killer |
|---|---|---|
| Crash Rating | Tested (ASTM/PAS68/IWA14) | Not rated |
| Vehicle Stopping Power | High | Medium |
| Visibility | Highly visible | Less noticeable |
| Maintenance | High | Low |
Use hydraulic road blockers where absolute vehicle stoppage is critical. Tyre killers are effective for moderate threat levels and locations requiring quick installation and deterrence.
