Yes, it can be canceled. The methods for canceling a self-scheduled Subject 3 test after successful reservation are as follows: 1. The Driving Test Center Information Platform allows for the cancellation of a scheduled Subject 3 test, with the latest cancellation time being before 12:00 on the day before the scheduled test date. 2. To cancel the Subject 3 test, you must bring your ID card and a copy of it to the Vehicle Management Office for cancellation. Additionally, you must write the following statement in the blank space of the ID card copy: "I voluntarily cancel the Subject 3 test scheduled on [date] at [driving school name]," and sign your name, provide contact information, and the date in the blank space. 3. If you are unable to come to the Driving Test Center in person, the person handling the cancellation on your behalf must bring their own ID card and a copy, along with the ID card and copy of the person canceling the test, and must also sign the cancellation request.

You can definitely cancel the appointment. I once canceled mine due to a sudden fever before the exam. Open the Traffic Management 12123 app on your phone, go to the exam appointment section, and you'll see your successfully booked session. At the bottom, there's a 'Cancel Appointment' button. However, note that online cancellation is not allowed within two days before the exam date. In such cases, you must quickly visit the DMV window with your ID card. After cancellation, the exam slot will be immediately released to others, and the system will send a confirmation SMS. But be aware, each cancellation wastes one exam opportunity, and frequent cancellations may lead to restrictions on your booking privileges by the system. If you really can't make it, it's advisable to cancel at least 24 hours before the exam to avoid last-minute hassles.

Hi, I just canceled my Subject 3 test appointment last month. The key is to watch the timing: you can cancel for free on the app within the first 24 hours after successful booking; after 24 hours but more than 2 days before the test, the exam fee will be deducted; when it's 1-2 days before the test, you have to visit the vehicle management office in person. Remember not to just wait after canceling—the system won’t automatically schedule your next test; you need to re-enter the booking queue, especially during peak seasons like winter and summer breaks, where securing a test slot is like snagging concert tickets. I recommend setting a phone alarm to remind yourself of the 72-hour deadline before the test.

Let me share three crucial points from my hard-earned experience: First, the cancellation button on the Traffic Management 12123 app is hidden at the very bottom of the exam information page—you'll need to search carefully like digging for treasure. Second, canceling within 48 hours before the exam will freeze your booking privileges for 7 days; a colleague of mine missed the prime summer practice period because of this. Third, if you've booked a slot at a less popular test center, the vacancy will be snapped up within half an hour after cancellation, so it's best to stay up until midnight to rebook. Oh, and driving school instructors say students with more than three cancellation records will need to submit additional documents for review the next time they book an exam.
