Fatal Head-On Crashes on Rural Two-Lane Two-Way Highways in Minnesota

This study aims to determine whether passing related maneuvers trigger the high number of fatal crashes on two-lane two-way highways. The public and others perceive that fatal head-on crashes are a result of drivers who attempt to pass others on two-lane two-way highways. Public officials advocate for additional passing lanes and four lane expansions to alleviate these fatal crashes.

The Minnesota Department of Transportation (MnDOT) reviewed 251 fatal head-on crashes on Minnesota two-lane two-way highways. After careful review of police crash reports, seven (7) of 251 fatal crashes involved passing. The remaining 97% of the crashes involved vehicles drifting over the centerline, losing control of the vehicle, weather, and incorrect lane use. Drifting over the centerline alone accounted for 162 (65%) of the fatal crashes.
