Hello I had an accident last week SA evening. Luckily I didn’t blame. He pulled on my lane in the curve and hit me at the front right of the fender. Didn’t call the police because we changed our data and the cars were still capable of driving. He then gave me his data +insurance and also gave to that he was to blame called his insurance company and asked if he reported the accident. Did he not do it until today then I given his data and my license plate and so on and it explained at tel. So now my question I get the days a write of his insurance should fill out and send it back or should I immediately inform the expert and the report then immediately??? Thank you in advance
