Christopher James Lambert

Trooper Christopher Lambert was struck and killed by a vehicle while investigating the scene of a prior crash on I-294 near Willow Road in Northbrook.

He was en route home when he encountered the three-vehicle crash on the left shoulder and stopped to render aid. He positioned his vehicle to protect the crash victims and he was standing outside of his vehicle when he was struck by another vehicle that failed to slow down or move over.

A nurse who was on the scene performed CPR until rescue personnel arrived. He was transported to Glenbrook Hospital where he was pronounced dead a short time later.

The investigation revealed that the driver who struck him was attempting to pass the accident scene by using the left shoulder and had admitted to smoking THC oil the previous day. He was charged with reckless homicide.

Trooper Lambert was a U.S. Army veteran and had served with the Illinois State Police for five years. He is survived by his wife, 1-year-old daughter, and parents.

In December 2019, I-294 in Cook County was renamed to Trooper Christopher Lambert Memorial Highway, between mile markers 49.5 and 50. Trooper Lambert's death was also a contributing factor to the state's "Move Over" Law, which requires drivers to steer clear of emergency vehicles on the highway.

The day before he was taken from his family Officer Lambert picked me up on the side of the interstate while I was walking to go get gas. He brought me back to my car while the States roadside assistance put gas in it. He kept me safe. In just our short interaction I could tell he was a caring individual who put others safety ahead of his own. My heart aches for his family.
