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.
Rumble strips are commonly used for the same purpose. 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.
The surface of this type of vibrating coating line is distributed and scattered with raised bumps. Some bumps are coated with high-refractive-index glass beads.When a speeding vehicle runs over the raised road lines, it produces a strong warning vibration to remind the car driver of deviation from the lane.
