Neat slalom from the big rig.
Not the van man's fault though,
there's a construction digger type tractor moving across all the lanes to turn right. This causes the bus to try to move left into the van before stopping completely. the van man who seems to have been waiting for the bus to pass him on the right so as then to move right is forced to halt as well.
Of all of them the big rig driver must have had the best view of what could unfold, as he sits up higher than the rest and would clearly see the digger. I agree with you Scott, he still gunned the rig on the main drag faster than he ought, just very lucky this time.
Scary, scary, combination of road junctions though.
The other question is just how and why was the slow moving digger in the fast lane trying to turn right across all the traffic?
