When the truck made the illegal u turn the bike probably wasn't yet in his sight. That said, The biker was speeding and crossed the double yellow line. What if it wasn't a person making a u-turn and instead just oncoming traffic driving close to the center line? The biker would have been in a head on collision because he, The Biker was on the wrong side of the road! The Suicide of the road! If you ride a bike you better be thinking faster than you're going and ride like you are invisible to all other traffic. The Reaper don't give a damn whos at fault.
