How is the age of a car calculated?

[DiGabriella]

The calculation method for a car's age is based on the registration date on the driver's license. The driver's license, also known as the motor vehicle driving license (referred to differently in various regions), is the legal document permitting the operation of motor vehicles on Chinese roads. After each annual inspection, a registration is made, which refers to the staff marking the supplementary page of the driver's license. If the registration is not completed after the annual inspection, it is considered as not having undergone the annual inspection, even if the vehicle has passed the inspection and has no issues. If caught by traffic police, it will still be regarded as not having undergone the annual inspection because there is no record in the backend system of the vehicle management office. The driver's license must be carried with the vehicle at all times; otherwise, the car may be impounded and fined until the owner can provide the driving license to retrieve the vehicle.
