did just watch it again, looks to me as if linfox truck has hazards on maybe? not sure stopped a long way back from the line if he is wanting to turn.
either way doesnt change my opinion of truck drivers i could drive around with a camera mounted in my car and edit all the bits to show the awesome tailgating, intimidation, dangerous lane changes, rolling halfway through an intersection cos the light *will* change *eventually* or the not even bothering to stop when they most likely could have and yes sometimes they cant but really i dont think the road laws allow for "oh that light changed you were probably going to fast anyway to stop by the time its RED so thats ok just steam roll through" well after its red
