Being a trucker myself, this sounds like the typical "oh I am gonna blow by this trucker before the construction zone" type of accident, which means, the bike was probably trying to zip around the truck, and the truck was moving over becuase his lane was ending in the construction zone. seen this happen on hwy 2 a million times. No one will let the trucks in so they get forced into either hitting pylons, or moving over.
GIVE US SOME DAMN ROOM!!!!!
if this was NOT what happened, then the driver of the truck is a complete idiot. What's not mentioned is if the truck had his siginal light ON to move over or not. If he DID, then the guy in the bike trying to zip by him probably shouldn't have tried something like that. If the truck driver did NOT have a siginal light on, I'll find the bastard and beat him senseless myself.
Too many morons out there who can't be bothered to use the siginal lights these days too.....
