Rumble strips are a road safety feature that alerts drivers when they are drifting from their lane due to distracted or inattentive driving. They are grooves in the roadway surface that produce noise and vibration when driven upon. This video shows how rumble strips are a proven and cost-effective method of reducing crashes on Minnesota roads. It also acknowledges the impacts to cyclists, recognizes the noise impacts to nearby residents, and describes the difference between rumble strips and rumble stripes.
