The automobile driver's incursion onto an active runway, which resulted in a collision with a landing airplane.

Factual narrative

The flight instructor reported that, while the student pilot was landing, a car did not stop at the hold short line and drove onto the runway. The car struck the left wing, the airplane nosed over and came to rest on the runway. The driver of the vehicle reported that, he stopped at the entrance of the runway and checked left and right to make sure it was clear. While crossing the runway he heard glass shatter and a heavy impact. At no time did he see the airplane, until after the collision. The airplane sustained substantial damage to both wings, the fuselage and empennage. The flight instructor reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
