centerline rumble strip

A: Centerline rumble strips are an effective safety tool used to address head-on, sideswipe and crossing-the-centerline crashes on two-lane, rural highways resulting from driver inattention, error or fatigue.

In a 2003 research study by the Insurance Institute for Highway Safety, “Head-on and opposing-direction sideswipe crashes---the primary target of centerline rumble strips---were reduced by an estimated 21 percent, while head-on and opposing direction sideswipe crashes involving injuries were reduced by an estimated 25 percent.”
