It looks like the truck trailer is missing its right rear wheel and is supported by a stack of lumber.....so it was probably not moving at the time of the accident.
That would wreck your day. Wonder if his mother-in-law was in the back seat telling him how to drive? If she was she's toast now Hopefully the driver leaned over REAL fast.
Notice that there are no dual wheels being used on the truck.. The tires were way overloaded with those extra large Washington trees.. No wonder they had a tire problem on the log hauler.
