Exit-Only Spike Barriers

In this image, a series of robust, spring-loaded spikes lies flush with the pavement on the exit side of a roadway. When approached head-on from the proper direction, the spikes gently give way, allowing traffic to exit without obstruction. However, if someone attempts to drive in from the opposite end, the angled spikes catch and threaten to puncture tires, effectively preventing unauthorized entry. Commonly installed in parking garages, security perimeters, and controlled-access areas, these one-way barriers help maintain orderly, regulated traffic movement and deter rule-breaking attempts.
