A preliminary investigation shows the 36-year-old man was driving a 2000 Harley Davidson.

Wilde said the motorcycle was traveling southbound on Route 83 when it struck the rear of a white 2022 Nissan.

The force of the collision caused the motorcycle to veer into the oncoming northbound lane where it struck a silver 2008 Acura SUV.

The driver of the Nissan and Acura have been cooperating with police throughout the investigation, Wilde said.

Page said the drivers of the two cars were treated at the scene and did not require transport to the hospital.

The crash remains under investigation by the Round Lake Beach Police Department and the Major Crash Assistance Team of Lake County (MCAT).

Route 83 remains shut down as of Monday afternoon as Round Lake Beach police and MCAT continue to investigate.
