Report Date:  05/15/2008


The Federal Highway Administration (FHWA) defines rumble strips "as raised or grooved patterns on the roadway shoulder that provide both an audible warning (rumbling sound) and a physical vibration to alert drivers that they are leaving the lane." Cities and counties may use rumble strips as means of enhancing safety to help warn motorists to slow down in anticipation of a stop sign or to help warn motorists that they are leaving the roadway or crossing the centerline.
