Raised markers (chatter bars) are safety equipment that prevent vehicles from straying into other lanes, which could cause a head-on collision, by visual guidance using reflective materials and physical vibration if the markers are run over. Road studs are small raised markers suitable for narrow roads, etc. where it is difficult to install regular raised markers. Also, they can be installed on curbs and center medians to clearly indicate the road lines and prompt drivers to drive safely.
