But if those two cars really belong to their bureau, it will involve the private use of the bus. If the traffic police at the scene of the accident made an investigation, it must have been divided into a primary responsibility and a secondary responsibility. For example, your husband is responsible for 20% and the other party is responsible for 80%. You can hire a professional lawyer to do forensic identification, and let the lawyer specifically calculate the amount of your husband's loss and multiply it by 80% to ask the other party for compensation.
If the car belongs to the Land and Resources Bureau, it will be compensated by the Land and Resources Bureau or shared by the Land and Resources Bureau and the driver.
If it is a private car, the driver will pay.
If, after investigation or investigation by the traffic police, the driver has a major responsibility in the accident or intentionally caused the accident, then the driver will bear criminal responsibility.
I suggest that you hire a professional lawyer and then bring a lawsuit to the people's court. This is the most correct and effective method. We have to accept hundreds of such traffic accident cases a year, and there will be laws to uphold justice for you.
