A rounded, raised ceramic or plastic marker glued to the road surface to delineate lanes. These markers provide tactile and auditory feedback when a tire rolls over them, alerting distracted drivers that they are drifting out of their lane. Highway crews and truckers use this nickname due to the marker's dome shape.
