What does it mean when a driver's license has not been reviewed on time?

[LaJasper]

Failure to review on time means that the required review was not conducted, resulting in overdue status. The handling methods for an overdue driver's license review are as follows: 1. Within one year: If the driver's license has been overdue for review for less than one year, the normal renewal procedures can be followed, meaning the same materials and process as a regular review. 2. Over one year: If the review is overdue for more than one year but less than three years, the applicant must first pass the subject one exam at the vehicle management office before proceeding with the renewal. 3. Over three years: For a Class C license, if overdue for three years, the license will be invalidated directly. For Class A and B licenses, if overdue for three years, the license will be downgraded, and the driver must complete the downgrade process at the vehicle management office within 30 days. Failure to do so will result in the vehicle management office directly announcing the cancellation of the driving qualification for the corresponding vehicle class.
