UPDATE: After a serious crash Tuesday morning that resulted in a car stuck under a semi-trailer, Chattanooga police have re-opened Bonny Oaks Drive to traffic.

The crash blocked Bonny Oaks Drive for about eight hours as they worked to investigate what happened and remove the vehicles.

"It made a turn and was pulling out of the parking lot across the street. While it was pulling out the white car was coming down Bonny Oaks and ran under the truck,” said Sgt. Justin Kilgore.

Chattanooga Police tell Channel 3 the crash happened around 1 a.m. on Bonny Oaks near Bonnyshire Drive.

Rob Simmons with CPD said the car had three children and two adults were inside the car. All five victims were rescued from the car by the Chattanooga Fire Department and brought to a hospital, one of them has life-threatening injuries.

The cause of the crash is still under investigation, but investigators believe heavy fog may have contributed to the crash.

"This morning when first responders got on the scene it was really foggy, which may have caused part of this crash,” Sgt. Kilgore said.

During the cleanup, the semi was leaking fluid onto the road. Police say it was likely brake fluid, and don’t believe it’s harmful to the environment.

For eight hours traffic investigators used digital scanning devices to process the scene. It’s technology that can shed light on what happened.

“We can actually put the vehicles in motion to see some of the way the crash occurred, we can see how much of the crush is on the car, we can overlay another car on top of that and that image we can see how much crush is on the car which can also help us with speed,” Sgt. Kilgore explained.

Bonny Oaks was closed at the scene of the crash during the morning commute.

The victim’s have not yet been identified.
