At 0:16 the truck was responding to the vw by moving left prior to the vw crossing the white line. The truck appeared to properly not over react with excessive braking that could have caused an another wreck between whatever was being air towed behind his trailer (OTR drafting) that we don't see. I see the rig keeping up with the speed of traffic, no intent to excel (I did not a hear audio reporting a speed up either), others may differ.
I would talk pretty hard to the OTR about the fact that his flasher should have gone on when he began to move left and we should be hearing a constant horn from the rig on the audio.
I may have cited improper lane change and reckless driving to the vw, if there were no injuries. With injuries I would have only cited lane change viloations, and asked for BAC after transport. The reckless driving cite would include examination for impaired driving.
The citation(s) if any has as much to do with prior record and the LEO interview as anything else. Whoops and sorry does help, honestly in all comments. The VW issue could be one of many simple mistakes we make daily, just at a deadly wrong time.
The truck would likely have their logs reviewed by a dotcop in most states. OTR driver outcomes are based more on data record accuracy over the interview. Given collabrative negative input from those who report as witness behind the accident and the logs would picked apart word by word....
