Almost everyday I come across an incident involving a HGV and a car. 9/10 the Truck is LHD and has moved out into the right hand lane, hitting the smaller vechle. Too many blind spots and lack of driver care/attention in my opinion.
OP, if you think it's worth reporting then do it. As some other members on here have said it would probably make more of a difference if it was to his Boss, rather than police.
