Within one year after the replacement period, if the driver's license is overdue, the driver can go through the formalities at the vehicle management office with his ID card, invalid driver's license and physical condition certificate issued by medical institutions at or above the county level, without taking any subject examination.
If the driver's license exceeds the renewal period by one year instead of three years, the driver's license will be in the state of "cancellation and recovery" during these two years. In other words, although the driver's license was cancelled at this time, it can be restored. As long as the driver goes to the vehicle management office to take the subject one exam and passes the exam, he can go through the formalities of replacing the card normally.
If the driver's license exceeds the three-year renewal period, the driver's license status is "cancelled", that is, the driver's qualification is cancelled and cannot be restored. Drivers need to take all the exams and get a new driver's license, just like the students who took the driver's license for the first time.
