Looks like the initial reports from news station that the aircraft only hit a light pole and the light pole hit the truck were right. Everybody saw the dash cam from the truck and were convinced that the plane wheels must've hit the truck but from the image of the truck's damage, it doesn't seem the plane's wheel touch the truck.
