What We Know About the Deer Park Crash at Lake Cook Road and Quentin Road
On a Tuesday afternoon around 3:15 p.m., at the intersection of Lake Cook Road and Quentin Road in Deer Park, Illinois, a serious crash led to a tragic loss of life and several injuries. Investigators in Lake County reported that a Honda Accord had broken down, and its driver got out to look under the hood. Another vehicle, a Honda HR-V, then struck the Accord, fatally injuring the man who was beneath it. According to officials, passengers in both vehicles were injured, though they were expected to recover. A school bus was sideswiped in the incident, with only the bus driver inside, who was not hurt.
This junction, which sits along the busy Lake Cook corridor and serves local traffic bound for Deer Park Town Center, nearby neighborhoods, and forest preserves, often carries steady afternoon traffic. That is important context for understanding how quickly risks can escalate when a vehicle becomes disabled in or near a travel lane during the after-school and after-work hours.
Location and time
The collision occurred at Lake Cook Road and Quentin Road in Deer Park, around the 3:15 p.m. hour. Afternoon light, commuting patterns, and typical suburban arterial speeds can combine to make roadside breakdowns particularly hazardous during this part of the day.
Vehicles and parties involved
Two primary vehicles were involved: a Honda Accord that had reportedly broken down, and a Honda HR-V that struck the Accord. A school bus was also grazed. The Accord’s driver, who was outside his vehicle at the time, sustained fatal injuries. Passengers in the Accord and HR-V were injured but expected to be okay based on early information from investigators. The bus driver reported no injuries.
Investigation status
Major crash investigations typically span several weeks and may involve scene measurements, vehicle inspections, event data recorder downloads, and toxicology. In a multi-vehicle crash with a fatality, investigators carefully determine pre-impact vehicle positions, impact dynamics, and driver actions before assigning final contributing factors. Families and injured passengers often find it helpful to know that these steps take time and that additional details can emerge as investigators complete their work.
