The North Dakota Department of Transportation (NDDOT) is currently implementing a Centerline and Edgeline Rumble Stripe Program across North Dakota. The stripes have been installed on many of our two lane highways as a safety measure to help prevent traffic fatalities and injuries from motor vehicle crashes. Rumble stripes are grooved patterns on the roadway that provide a rumbling sound and physical vibration, immediately alerting inattentive drivers they are leaving their driving lane. Rumble stripes are an effective countermeasure for preventing roadway departure crashes.
