Ensuring Exit-Only Access

In this photograph, a series of robust, sharply angled metal spikes is set flush with the pavement of an exit lane. Designed to collapse under forward-moving tires but rise against reverse movement, these traffic deterrents ensure cars cannot re-enter once they have exited. This simple yet effective security solution is commonly employed in parking garages, secured areas, and gated properties to reinforce proper traffic flow and deter unauthorized access.
