A road closure was put up and my vehicle was parked within it, work was being carried out close to me but away from my car. There was also right next to my passenger side 2 cones and a metal post sticking out of the ground, the 2x cones where there i guess to alert for the post but when i got in my car i didnt see them. The cones were 45cm high to be exact. I hit a cone and the temporary metal post sticking out of the ground. Scraping my vehicle. It was 30mph road and very small cones so i didn't see them next to my car when i got in. Is this my fault or should the company who put the cones and post out pay for this? As they should have maybe left a note one my car?
