Fault probably depends on a number of facts that we don't know: 1) whether the truck was parked (or stopped) in the lane illegally, or just backing out of the driveway normally; 2) whether path 914 was going a safe speed; and 3)whether path914 left a safe amount of room between his car and the car in front of him. There are probably some others that I can't think of at the moment.
