From the insurer's point of view the driver of the private vehicle was at fault.
But this is not to say that the lorry driver demonstrated good driving.
He could slow down and accommodate the pushy drivers.
The point is that lorries hate to slow down; they like to maintain speed due to the time it takes them to get back to cruising speed.
Or perhaps he was just not alert enough? We should not assume that he actually saw everything that the camera did.
Legally, the lorry driver is in the clear. But it does seem that a good driver could have avoided the crash.
I think you are splitting hairs a bit.
A murderer, would not be a murderer if he / she did not kill. Maybe they were molested, maybe the victim threatened them or their family, maybe...plenty of maybes that can be thrown into this.
I doubt there was anything else going there, as the car driver was joining from the slip road, so it is unlikely there was 'history' between these two drivers.
Also, if you ever driven the lorry, you would know that at the point of the impact, the car would be in his blind spot, hence not clearly, if at all visible.
The lorry driver did not change the speed, or the his line of travel, he did however proceed straight to the hard shoulder, to avoid somebody else rear ending him or the car.
In my opinion, it is not just legal aspect the lorry driver dealt with quite well, but the moral one too.
And, they do not like to slow down, and yes they do overtake one another blocking three lanes on 4 lane motorways, and they do overtake for 10min, when one is doing 0.5km more than the one on the inside...and I hate them for all of these things
But, in this case, seeing the little clip I cant say I believe he should be blamed for this incident. Good driver can prevent some situations, but also, good driver dont try to squeeze in front of 40t artic, just because he cant be ****d to ease off his accelerator and merge behind it
