To know which insurance company underwrites auto insurance, you can refer to the following methods:
1. The traffic insurance sign in the upper right corner of the front glass will show which insurance company it is;
2. The policy provided when buying a car can be viewed (the policy is stamped with the official seal of the insurance company);
You can also try to check with the vehicle management office. You need to provide a copy of the compulsory insurance contract during the annual inspection of the vehicle.
