Rumble Stripe Impact
|Event Date:||November 20, 2013|
Rumble stripes are an effective countermeasure for preventing roadway departure crashes. The noise and vibration produced by rumble stripes alert drivers when they leave the traveled roadway. Rumble stripes is the term used for stripes painted with a retroreflective coating to increase the visibility of the pavement edge at night and during inclement weather conditions.
Included in the 2013 INDOT Goals, implementation of rumble stripes are currently taking place statewide with 30 projects covering 238 project miles. (See map on right)
