Rock chipped windshield

BeechSierra, sorry, but I am going to highjack this thread a little bit, and ask a question of some of the legal minded members of the forum.

What if this rock that chipped BeechSierra's windshield can off of a truck, hauling gravel? If you could get this truck to pullover, could you make a damage claim against that driver?

Or, what if the truck just pulled out of a construction area, and did not "clear" its tire treads, and a stone gets loose from his dirty tires, and then the rock/stone smacks your windshield?

Or one more, what if a car or truck has a tire blowout, and part of the tire hits your car and does damage?
