Raised Rumble Strips
Raised rumble strips are 50- to 305-mm-wide rounded or rectangular markers or strips that adhere to new or existing pavements. Some road agencies use raised buttons. Because their height can range from 6 mm to 13 mm, use of raised rumble strips is usually restricted to warmer climates that don't require snow removal (see the Issues section).
