Dangerous driving crazy undertaking by lorry in UK - Dashcam

Watch this lorry .. I was behind him for a while .. there was a 50mph temporary speed restriction on the motorway .. but the slow lane had slowed down to around 41mph and the lorry driver just got impatient and undertook the car in front .. not great driving in my opinion .. And I can’t see that he didn’t know what he was doing, he was in the right lane for his journey for a couple of miles before he made this silly manoeuvre ..

He probably just thought that was his exit, then realised it wasn’t last minute. Still very dangerous driving though

Send this to the hgv’s company. Lane is clearly road marked and signed as turnoff.
