Subject 1 exam appointments can be canceled without any impact on the candidate as long as the cancellation is made within the stipulated time frame. According to Article 43 of the 'Regulations on the Application and Use of Motor Vehicle Driving Licenses,' if an applicant is unable to attend the exam at the scheduled time, they must apply to cancel the appointment at least one day in advance. Failure to attend the exam as scheduled will result in a failing grade for that attempt. It is important to note that the system allows a maximum of three cancellations. Exceeding this limit will lock the system, preventing any further cancellations for all subsequent exam subjects. To cancel a Subject 1 exam appointment, the request must be submitted one day in advance. Same-day cancellations are not permitted if the candidate is unable to attend. If the exam has not yet been successfully scheduled and is still in the pending status, the cancellation can be processed online by logging into the 12123 APP. Navigate to the homepage, click 'More,' enter the 'Business Center,' locate the 'Driving License Services' section, and then select 'Cancel Exam Appointment.' Follow the prompts to cancel the desired exam session. If a confirmation SMS for a successful appointment has already been received, the candidate must bring their original ID card and a written request for cancellation to the local vehicle management office. Submit the application and materials to the staff for review to proceed with the cancellation.

I had scheduled the subject one test but had something come up last minute. I specifically asked my instructor, who said it can be cancelled. You just need to operate it on the 12123 Traffic Management APP, and cancelling even one day before the test is fine. This way, rescheduling won't have any impact—the system won't specially mark you, and you'll still queue normally. The worst thing is missing the test without notice—that counts as a fail, and your next scheduling might be ranked lower, making you wait longer. It's advised to immediately reschedule after cancelling, especially during peak seasons when test slots are tight. I also found that frequent cancellations affect efficiency since each cancellation puts you back in the queue, prolonging the time to get your license. So, always confirm your schedule before booking a test. If you really need to reschedule, cancel decisively—it's better than missing the test.

Last time when I had the subject one test scheduled, I canceled the appointment due to a typhoon. I called the vehicle management office and they said cancellations are allowed as long as they're done on the 12123 app before the exam starts. The key point is that canceling itself doesn't cost money or deduct points, and there's no record at all—it's purely for personal schedule adjustment. However, missing the exam is different; the system automatically counts it as one failure, and you have to bear the consequences. Rescheduling is quite convenient now—just a tap on the phone puts you in the queue. Having canceled once didn't make me feel slower than others. The driving instructor reminded me not to cancel too often, as test center schedules are limited and others are waiting for slots. I think the most crucial thing is to plan your time well. If you have to cancel, quickly book the next available session, as delaying too long might mean missing a suitable time slot.

During my driving school training, I found canceling the subject one exam was quite simple. The instructor taught me to use the 12123 app - the cancellation button is right under the appointment page, and completing the cancellation one day in advance won't affect subsequent arrangements. The most important thing to avoid is missing the exam without canceling, as the system will directly record it as an absence and count it as one failure. I specifically checked the new regulations - canceling appointments doesn't affect other subject exams nor lower your scheduling priority. However, note that local regulations may vary - some cities might impose short-term scheduling restrictions for frequent cancellations, but generally it's completely fine. I recommend taking screenshots when operating in the app to keep records, which can help when contacting customer service if issues arise.
