Is it true that I sent a text message saying that I have to pay a fine for violating the rules?

From the description, you can use the mobile phone WeChat to check whether your vehicle is illegal. If it is, it is true by comparing the illegal information on the Internet, otherwise it may be false.

Because according to the "Regulations on Handling Procedures for Road Traffic Safety Violations", a motor vehicle will notify the vehicle owner or manager by SMS or email within 3 days after uploading the illegal information management system. So pay attention to distinguish between true and false.
