Rumble strip on roadwayRoadway departure fatalities are a serious and often preventable problem.

The Federal Highway Administration reports that 54 percent of all highway fatalities in the U.S. are caused by drivers leaving their lane of travel.

What are rumble strips?

Rumble strips are grooved patterns that make a rumbling sound and physical vibration that immediately warns inattentive drivers that they are leaving their driving lane.

Why use rumble strips?

Rumble strips allow drivers to self-correct and avoid a crash. Our before and after crash analysis found that head-on fatalities were reduced by 40 percent with the installation of centerline rumble strips.
