Can I cancel the subject three test appointment on my phone if it's successfully scheduled?

If you have only successfully entered the appointment queue for the subject three test, you can cancel it on your phone. However, if the appointment is truly confirmed, you will need to go to the vehicle management office to cancel it. Here are the relevant details: 1. The first scenario of a successful appointment refers to when a student completes the appointment operation on the website and successfully enters the appointment queue, waiting for processing. At this stage, the appointment can be canceled on the phone; 2. The second scenario of a successful appointment refers to when the test appointment is truly confirmed, and the student receives a success notification SMS from the vehicle management office. In this case, the student must bring their ID card to the vehicle management office to cancel the appointment, and this must be done at least one day before the test. Otherwise, the cancellation will not be processed, and it will be treated as an absence.
