How many days in advance should I cancel my appointment for the driving test? How to cancel?

At least 1 day in advance. The provisions in the "Regulations on the Application and Use of Motor Vehicle Driving License" are: If an applicant cannot take the exam at the scheduled time for some reason, he shall apply for canceling the appointment one day in advance. If the applicant fails to take the exam at the scheduled time, it is judged that the exam is unqualified.

Successful cancellation can be divided into two situations:

1. If only the reservation application is submitted successfully, there is a menu to cancel the reservation on the homepage of this website. Just cancel the reservation according to the prompt. You can cancel your appointment online by yourself, and it will usually be accepted in three to five days.

2. If you receive a short message from the vehicle management office informing you that the appointment date is successful, you can only cancel it at the vehicle management office. You need to bring your ID card to the vehicle management office for filing before you can cancel the appointment. Cancellation on the spot takes effect immediately.
