Rumble strips and rumble stripes are a recommended strategy for crash reduction. The North Dakota Department of Transportation initiated rumble strip use in the 1970s and greatly expanded application of rumble stripes through a statewide initiative in recent years. This study of four intervention and two control road segments shows positive results with regard to crash incidence in before and after comparisons. The crash rates comparison considers crash severity, vehicle type, roadway factors, crash type, and contributing factors.
