Running a red light is the traffic violation of entering and crossing an intersection when the controlling traffic signal displays a solid red indication. This action is a leading cause of severe side-impact collisions, known as T-bone crashes. Traffic engineers combat this by installing red light cameras or adjusting the yellow light timing to account for heavy vehicle braking distances.
The dashcam footage shows the delivery truck run a red light and clip the front fender of the sedan.
