Rumble Strips provide warning of road conditions

Temporary rumble strips are comprised of a series of raised elongated bumps laid down on the surface of the roadway to provide both sound and vibration to alert motorists of changing road conditions, said State Maintenance Director Natalie Roark.

Temporary rumble strips are one of a number of safety devices used by the Missouri Department of Transportation to provide an additional layer of protection for everyone in work zones.

“Temporary rumble strips are comprised of a series of raised elongated bumps laid down on the surface of the roadway to provide both sound and vibration to alert motorists of changing road conditions ahead requiring your complete attention,” explained State Maintenance Director Natalie Roark. “These conditions could encompass any number of situations including lane closures, speed reductions, uneven pavement or work zones.”

According to the National Highway Traffic Safety Administration, distracted driving claimed 3,166 lives in 2017. Placement of temporary rumble strips is designed to give motorists enough time to react safely before encountering potentially hazardous road conditions, states a MoDOT release.

If a driver hears the rumble and feel the vibration, Roark advises drivers to not panic but focus on the road and be alert to changing conditions ahead.

To help inform drivers about this safety tool, MoDOT created an educational video that can be found online at https://youtu.be/if4JKLh5NBQ.

“Slow down, be alert and avoid distractions,” Roark said.
