Centerline Rumble Strips in Montana
Every year, about 70 percent of the lives lost on Montana’s roads occur from a vehicle leaving its designated lane of travel. Distracted, drowsy, impaired or other dangerous driving behaviors can cause roadway departure. Unfortunately, if/when the driver realizes the departure, it is too late. As MDT works towards the goal of Vision Zero, the implementation of safety improvements to existing roads is a critical tool in ending deaths and serious injuries on Montana’s roads.
MDT is currently installing centerline rumble strips as the newest safety measure on 2-lane highways across the state. Centerline rumble strips have been proven to reduce fatalities and serious injuries in other states across the country. While they are installed in both passing and non-passing zones, they are not meant to deter safe passing. Their purpose is to provide immediate feedback to drivers and motorcyclists unintentionally crossing the centerline of the highway.
In addition to their record in preventing roadway departure crashes, they are also cost effective! MDT’s Engineering staff have extensively researched the best safety solutions for our existing roadways; which includes careful consideration of the cost and benefit to the traveling public. Compared to $1 million per mile for total highway reconstruction, centerline rumble strips cost $5,000 per mile to install.
