For lower security applications, surface mounted passive 1-way spikes can be installed which incorporate spring-loaded spikes which are lowered by the movement and weight of the car as it passes in the correct direction. Any attempt to pass over the spikes in the wrong direction will result in multiple tire punctures. The spikes incorporate a screw mechanism to allow them to be manually locked in the down position to temporarily enable vehicles to pass in the wrong direction.
