First of all, according to your description, your motor vehicle is more likely to be identified as the whole or main responsibility for traffic accidents. In this respect, the traffic police need to issue a traffic accident certificate and report it to the insurance for the record. As for the compensation part, it depends on the actual loss of the injured person and the damage of your car. Generally speaking, if you only pay the compulsory insurance, you can pay within the limit whether it is the car damage or the injured part of the other party (1 10,000 yuan for disability-free injury treatment and 2,000 yuan for car damage, yes.
Secondly, some of the agreements you signed are mandatory, so you should call the police as soon as possible after signing them. This part is beyond traffic accident compensation. If you can prove that it was signed involuntarily at that time, the agreement is invalid, and if it causes serious consequences, you have the right to pursue the criminal responsibility of the other party.
