What is the test for a driver to be found guilty of dangerous driving in a collision involving a delivery truck?

Here, the delivery truck blocked defendants view of the entire right lane and at least part of the left lane. He simply had no idea whether it would be safe to passand yet he nevertheless pulled into the left lane on a dark but apparently busy road and, driving 70 miles per hour, tried to pass two vehicles at once. The jurors, at least some of whom were presumably licensed drivers, were undoubtedly familiar with basic principles of traffic safety and could reasonably infer that by ignoring them, defendant acted with wanton disregard for the safety of others.
