Though you didn't ask for it...

The other big mistake that I see at drivers school is hesitation when there is an emergency vehicle moving on course. If the vehicle is moving on course and is being covered with a white flag, pass him, but do so safely. Typically, if it is a rescue truck, there will be someone in the bed that points to which side you should pass. Otherwise, the vehicle typically hugs one side of the course, so pass on the other.
