I will take the exam for the second time tomorrow, and the driving school will be cancelled for no reason.

If there is evidence, you can complain to the traffic police brigade about driving school.

There are two ways to cancel the exam appointment:

1. If the system does not show that the reservation is successful, just go to the reservation page of 12 123 Traffic Management APP and click the Cancel Reservation option to cancel.

2. If you receive a short message that the vehicle management office has made a successful appointment, you can't cancel the appointment yourself. You must bring your ID card to the driving school examination department to write a written cancellation application, and then the driving school can submit it to the local vehicle management office for cancellation.
