At the risk of being flamed I have some Sympathy for the truck driver. Theres nothing infront of him, he is looking to the right for a gap ,sees one but now there is a cyclist in front possibly obscured by the high design of most tipper trucks.
We all make mistakes on the road noone (truck drivers or cyclists) is perfect. filtering in front of large vehicles is ultra dangerous in my opinion.
After a fatality lots of questions will have been asked , the vehicle checked and the drivers activities in the 24 hours prior will all be looked at.
Drivers computer records have been checked in the past to see if they were sleeping or surfing the net half the night prior to an accident so for us to make wild assumptions about what the driver did or didnt do is nonsense.
I think theres massive evidence that visibility from truck cabs isnt good enough .Better mirrors and windscreen design could all help reduce the death toll .In the meantime just dont go there.
