Slowstop is a parking sign that features enough strength to eliminate the usual wheel stops. The SlowStop Disabled/Handicap Parking Sign acts as a collision shield that does much more than block access. During a collision, the kinetic energy of the impact is progressively absorbed by an elastomer hidden in the base of this rebounding bollard. The post is able to tilt approximately 20° as it progressively absorbs energy, softening the impact. After the impact, the parking bollard returns upright, leaving your guard intact and ready to perform again
