Why don't you get illegal information every time you speed?

From the description, it may be that the owner of the motor vehicle did not enter the contact information of the mobile phone when entering the motor vehicle information, or the mobile phone number was entered incorrectly.

Because according to the "Procedures for Handling Road Traffic Safety Violations", the owner or manager of motor vehicles will be notified by SMS within 3 days after the illegal information of motor vehicles is uploaded to the information management system. Therefore, combined with the description, the reason why there was no notice may be that the mobile phone number left at that time was wrong, or it was not left.
