How is the validity period of a driver's license regulated?

[MacNorah]

Here are the specific regulations regarding the validity period of a driver's license: Within one year before expiration: The driver should apply for a license renewal at the vehicle management office within 90 days (three months) before the expiration of the driver's license. The license can still be renewed normally within one year after expiration. Between one and three years after expiration: The driver's license will be revoked, and the driver needs to retake the subject one exam to obtain a new license. If the driver's license has been expired for more than three years, it will be directly invalidated. The initial renewal period for a driver's license is 6 years. If no demerit points have reached 12 points in any cycle during these 6 years, a 10-year validity period driver's license will be issued upon renewal. If there is a case where 12 or more demerit points have been recorded within a year, a 6-year validity period driver's license will still be issued. When the 10-year driver's license expires, if no demerit points have reached 12 points in any cycle, a long-term valid driver's license can be issued.
