A collision involving two cars snarled traffic on Trussler Road early Saturday afternoon.
Witnesses at the scene said it happened as several cars approached a red light at Trussler Road and Huron Road.
While most cars managed to stop, a black car began to veer slowly to the side of the road, but struck the back corner of the car ahead, causing it to flip and roll into the ditch.
A handful of bystanders ran to help the couple get out of the car, who appeared to have minor injuries, but were both conscious.
Emergency crews blocked the southbound lanes following the crash, waving traffic through one direction at a time for about an hour.
There's no word on a cause or charges at this time.
