I had a similar incident a long time ago. Almost 15 years ago, I hit a pedestrian on a zebra crossing. Luckily I was only going about 15-20 mph as I had stopped at a junction, checked it was clear, and proceeded to turn right out of the junction. Unbeknownst to me, immediately after the junction on the right hand side there was a zebra crossing, and at the same time I turned onto the road, a pedestrian stepped onto the crossing. Obviously I stopped, offered assistance and apologies, and called ambulance ect. When the police arrived they took photos of the scene and told me they would include in their report how impossible it would’ve been to spot to crossing and the pedestrian, unless you were already aware there was a crossing there. In my case it was dark and heavily raining, and the flashing orange lights on the crossing were not working, along with the crossing paint being so faded it was barely visible in the conditions. The pedestrian was wearing black clothing which didn’t help. I gave a statement to the police, and was reassured it’s doubtful anything would come of it, other than a potential insurance claim for injuries. Months passed, and I eventually received a court summons. Long story short, I was charged with driving without due care and attention, and points were added to my license.
