The North Luzon Expressway's raised plastic transverse rumble strips approaching Balintawak Toll Barrier, Philippines. Rumble strips (also known as sleeper lines or alert strips) are a traffic calming feature to alert inattentive drivers of potential danger, by causing a tactile fuzzy vibration and audible rumbling transmitted through the wheels into the vehicle interior.
A rumble strip can be a series of simple troughs, typically 1 cm (0.4 in) deep and 10 cm (4 in) wide, that is ground out of the asphalt. Other alternatives, similar to the Botts' dots, use raised strips, painted or glued to the surface. A specific form of raised strips using thermoplastic is called profile thermoplastic markings.
Later on, rolled-in strips on asphalt shoulders and formed-in strips on concrete shoulders were two of the earlier designs used in installing shoulder rumble strips by a number of U.S. states. A major limitation was that they had to be installed with new pavement. There were also difficulties in consistently obtaining the desired shape.
