A minor accident and a ban on stopping?

So, I had a little accident today. And that’s when I wanted to leave school with us, I hit a car when I parked out. Not at all. Are there three dents in there and the bumper at the back is a bit broken. But what interests me is: was he allowed to stand there at all? Because: (did he do a sketch there, hope it works) and it says on the sign: only for motorcycles (or something like that) and now I wonder if he’s there. Well, would I be interested? Thank you LG Kiki P.S. I can’t put my sketch on… can someone help me how that could work? Or I’ll send it to you… Thanks
