Shoulder and centerline rumble strips are used to reduce lane departure crashes. Portable rumble strips, also called Andreas strips, can be used to alert traffic to upcoming lane closures or road works to prevent collision with signage and barriers. They may cross the entire road from shoulder to shoulder, or they may only be in the wheel paths. They are used to alert the driver of an upcoming intersection, toll booth or similar hazard. Transverse rumble strips are placed in the travel lanes where most if not all vehicles will cross them. Rumble strips are divided into transverse rumble strips, shoulder rumble strips, and centerline rumble strips, depending on how they are used.

Rumble strips are also known as audible lines, sleepy bumps, wake up calls, growlers, drift lines, waker-uppers and drunk bumps.Ĭonvex road lines, raised thermoplastic pavement lines isolated CSRS and centerline rumble strips effectiveness 7.1 Effectiveness of CSRS on different classes of highway.6.3 Continuous lane rumble strips (CLRS).
