Failure to break to avoid collision or accident. Once the red truck hits the shoulder or grass, he's kicking up stuff, break lights glaring as the truck is slowing, the following pick up needs to let off the gas and prep for the worst. For some yet-to-be-explained reason he was trying to keep pace with the governor, and did not break to avoid the hazard the red truck unintentionally created.
Geez. We all agree the white truck driver could have possibly done more to avoid the danger. We really don’t have ANY details about what he observed. And you’re just speculating about flying gravel and screaming brake lights.
The ONE thing we DO know is that the red truck left the highway. The white truck was not LEGALLY required to stop, slow, veer, follow him or do anything else. He could have done any of those, but we don’t know what he saw in those few seconds. He may have been focusing on the approaching “emergency” vehicle. As best we can tell, he simply maintained his course. When the red truck veered back onto the hightway, HE-—not the white truck driver-—was in the wrong. That is not disputable. That’s all I’m saying.
