Tire-killers series blockers are designed as a platform with retractable spikes that pierce motor vehicle tires. The blocker is installed directly on the road surface. The blocker platform is shaped as “speed bumps” which makes the vehicles reduce their speed but not block them when entering the territory. In its active state, Tire-killers spikes are raised. Tire-killers road blockers are installed at stadiums, exhibition grounds, government offices, etc.
