1. At present, some provinces and cities have begun to implement electronic insurance policies. As long as the electronic insurance policy has come into effect, the traffic police department can normally produce a copy of the insurance company's electronic insurance policy when inquiring, and it is not necessary to post the traffic insurance sign on the vehicle. However, since the electronic auto insurance policy has not been implemented uniformly in the whole country, you can consult the traffic control department of your city. If it is not implemented, vehicles without paper signs may face penalty points and fines. In order to avoid this situation, if the electronic insurance policy has been implemented in this area, it is still recommended to put up a sign of compulsory insurance and not to tear it off too hastily.
