New dash cam footage shown in court in Louisville shows a semi-truck driver as she swerves and nearly crashes over a bridge back in March. The dash cam footage was presented in court Wednesday by the Jefferson County Attorney's Office in a criminal case against a pickup driver who is seen on the March 1 video swerving in front of a semi-truck trailer. The tractor trailer then plows through the bridge's railing and dangles over the water. 26-year-old Sydney Thomas, the driver of the semi-truck, was rescued by Louisville firefighters. The driver of the pickup truck has been charged with four counts of wanton endangerment and one count of operating a motor vehicle with a suspended license.
