How long can the renewal of a C1 driver's license be delayed?

[MaximusFitz]

Article 57 of the "Traffic Regulations and Penalty Points Rules": Motor vehicle drivers should apply for license renewal at the vehicle management office where the driver's license was originally issued or at another vehicle management office within 90 days before the expiration of the driver's license. If the driver's license is expired, traffic police will impose a fine but no penalty points. There is also a deadline for license renewal. If the license has been expired for less than one year, the renewal can proceed through the normal process; if expired between one to three years, the license will be revoked, but it can be reinstated by passing the subject one exam; if expired for more than three years, the license will be permanently revoked. When applying, the applicant must fill out an application form and submit the following documents: the motor vehicle driver's identity proof; the motor vehicle driver's license; a medical certificate issued by a county-level or military regiment-level medical institution. For those applying for a special small automatic transmission passenger vehicle for the disabled, a medical certificate issued by a specialized medical institution designated by the provincial health authority must be submitted. Details regarding the renewal of an expired driver's license: You can apply for license renewal within 90 days of the license's expiration, either at the local vehicle management office or online. When renewing, after filling out the renewal application as needed, the applicant must bring their ID card, driver's license, medical examination report, and other relevant materials. A recent one-inch color photo with a white background and no hat is required for the renewal. If the photo is not up to standard, a new one must be taken. After the motor vehicle driver's license is renewed, the original license becomes invalid and cannot be used again. The driver must properly keep the personal information on the driver's license and not discard it carelessly to avoid information leakage, which could cause issues during the use of the driver's license. Regarding renewal: Before renewal, all traffic violations associated with the license must be resolved; otherwise, the renewal cannot be processed. Processing locations: License renewal can be done at the vehicle management office where the driver's license was originally issued or at another vehicle management office. Renewal can also be done through the mobile app "Traffic Management 12123" or via the vehicle management office, traffic management department, or public security authorities. Photos and medical certificates required for renewal can be brought by the applicant. If concerned about their validity, these can be processed directly at the traffic police office to save time. 12123 Operation Method: Open and log in to the Traffic Management 12123 app. First-time users must register. On the homepage, find and click on "Driver's License Renewal and Replacement" under the driver's license business process channel.
