If the injured person can't close the case without signing or making excuses, the insurance company will probably say that it can't apply for compensation on the grounds that the case has not been closed. In fact, it doesn't matter even if the injured person doesn't cooperate. He can consult with the traffic police team. If the traffic police team can't solve it, he can apply to the insurance company with the tax and close the case after one year. Because of accidental injury, the prosecution is only valid for one year, and the insurance company's compensation is invalid for two years.
If both parties bring a lawsuit to the people's procuratorate, and the other party does not deserve it, it is no problem. As long as sufficient direct evidence can be produced, the people's court can pronounce the sentence as usual, and the other party must execute it after the verdict is pronounced. The most harmonious way is not to negotiate, but to agree that the injured cooperate with each other and find insurance companies to settle claims together.
Road traffic accidents are attributed to accidents, and the obligations that should be undertaken cannot be earned. In short, if the injured person doesn't cooperate, leave it alone. If he is cured and refuses to be hospitalized, he can stop paying medical bills and drive him to court. If the other party is arrested within one year, it will be impossible to file a lawsuit after one year, which means that the other party will not be able to pay a large amount of compensation. At that time, you only need to take the tax bill to the insurance company to apply for closing the case, and the insurance company will reimburse the cost of this claim.
