"bangle for president"
The rider moving right would of most likely expected the truck to be doing a straight right hand turn to be heading the same direction as the bike, not back across his path.
that's the problem...don't expect anything
and look at 6-7s, there is even a guy standing on the road warning oncomming traffic.
that truck driver didn't do anything wrong, the biker just paniced and lay down his bike
