While driving along A19 behind a Durham county council tipper type transit it's load of plastic facia & guttering starts blowing off doing about 55 mph I pull into outside lane speed up to about 70 to get past ( not quick enough ) a 4 mtr length of guttering comes across the front of the car, go straight over it both front wheels, car instantly start vibrating, tipper pulls in, I pull in next lay by and wait he pulls in when I flag him down. Anyway results in car having two buckled wheels cracked bumper passenger side lower ball joint pushed back and various scratches on body.6K of damage, this happened 3 weeks ago van driver hasn't give a statement so council insurance won't do any thing about it.Any idea where I stand with this?
