Traffic control spikes are ideal for controlling traffic direction and speed through a controlled entry location. Traffic spikes prevent vehicles from proceeding through a traffic lane in the wrong direction by enforcing one-way traffic lanes. Flush mount spikes are available with Spring Retraction or with Weighted Retraction. Speed bumps force drivers to slow down while driving through the controlled entry point. They are also ideal for keeping vehicular traffic at a safe speed while driving over traffic spikes.
