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.

The effectiveness of shoulder rumble strips is largely dependent on a wide and stable road shoulder for a recovery, but there are several other less obvious factors that engineers consider during design. In favorable circumstances, rumble strips are effective (and cost-effective) at reducing accidents due to inattention. Rumble strips may also be installed in a series across the direction of travel, to warn drivers of a stop or slowdown ahead, or of an approaching danger spot.

A rumble strip is applied along the direction of travel following an edgeline or centerline, to alert drivers when they drift from their lane. Rumble strips (also known as sleeper lines or alert strips) are a road safety 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.
