The purpose of this survey is to collect information from Michigan road users regarding the performance of centerline rumble strips on Michigan two-lane highways. Centerline rumble strips are a pattern of depressions installed on the centerline of two-lane highways to alert distracted or drowsy drivers that they are crossing the centerline. Many states have reported reductions in head-on and related crashes after installation of centerline rumble strips. Your participation in this effort and your responses to these survey questions would be greatly appreciated. Thank you for your participation.
