Looks as though his front wheels were over your towing bracket/ bumper bar. So he was firmly stuck Into you. No wonder you were pushed into the fast lane and then and then had to drag him into the first..the chassis must be bent seeing the position of the tow bar.Best of luck with the insurance.The driver didn’t appear inebriated to me, and as I was breathalysed I’m sure he was too,
I was busy clamping off a ruptured fuel pipe on the Megane that was pouring fuel into the rear of the motor home, after I had helped my wife over the crash barrier to relative safety I took the chance to isolate my rear battery, all scary stuff
I take my hat off to the emergency services, they where there in twenty minutes, but watching heavy trucks approaching while a good portion of my vehicle was sticking out into the slow lane is very unpleasant to say the least,
