Impaired Driving: Alcohol and drug impairment remain the leading cause of wrong-way crashes. Intoxicated drivers may fail to recognize traffic signs, enter an exit ramp by mistake, or continue driving against traffic without realizing it.
Distracted Driving: Drivers who are looking at a cell phone, GPS, or other distractions may miss “Do Not Enter” or “Wrong Way” signs and inadvertently enter the wrong side of a roadway.
Fatigue: Drowsy drivers can experience slower reaction times, impaired judgment, and confusion similar to alcohol impairment. Fatigue is especially dangerous during overnight travel when many wrong-way crashes occur.
Driver Confusion: Complex highway interchanges, unfamiliar roads, poor lighting, faded pavement markings, and confusing lane configurations can contribute to drivers entering the wrong roadway, particularly visitors or elderly motorists.
Missed Exits and Unsafe Maneuvers: Instead of safely continuing to the next exit, some drivers attempt to reverse, make illegal U-turns, or enter an off-ramp to correct a navigation mistake. These reckless decisions can place them directly into oncoming traffic.
Poor Roadway Design or Maintenance: In some situations, roadway conditions contribute to a wrong-way collision. Missing or damaged signs, inadequate lighting, worn pavement markings, obstructed visibility, or improperly designed intersections may create confusion for drivers. When this happens, a government entity or another responsible party may share liability.
Medical Emergencies: A driver experiencing a seizure, stroke, diabetic emergency, or other sudden medical event may become disoriented and unintentionally travel the wrong direction. Whether the driver is legally responsible depends on the specific circumstances and whether the medical emergency was foreseeable.
