If you have only successfully submitted the appointment application, there is a cancel appointment menu on the homepage of this website. Follow the prompts to cancel the appointment. If you have already received a text message from the DMV notifying you that the appointment was successfully scheduled, then you can only cancel it at the DMV.

A few days ago, I helped my cousin cancel the subject one exam reservation using the Traffic 12123 APP, and the whole process was quite simple. After logging into the account on the mobile APP, click into the exam reservation section to view all reservation information. Locate the subject one reservation record you want to cancel, and there will be a cancel reservation button inside. However, it's important to note that you must operate at least one day in advance; if you try to cancel on the exam day, it will be too late. After successful cancellation, the system will send a confirmation SMS, allowing you to reschedule for another time. Each cancellation counts as one opportunity, so avoid frequent cancellations to prevent restrictions on reservation attempts.

Canceling the subject one (theory test) appointment via the Traffic 12123 app is actually quite straightforward. Last time I canceled, I found that after logging into the account, just click 'More' on the homepage to enter the service center, then select 'Exam Appointment' to view the scheduled test list. Locate the subject one appointment entry, click into it, and finally hit cancel. The key is to remember this must be done at least 24 hours before the exam time - after that the button grays out. Upon successful cancellation, you'll need to rejoin the queue for a new appointment, so choose your timing carefully. The whole process takes less than three minutes, far more convenient than queuing at the DMV.

To cancel the subject one test appointment, you need to use the Traffic 12123 APP. After logging in, click on the exam appointment function, find the record you want to cancel, and click the cancel button. However, it must be completed one day before the exam; cancellation is not possible on the same day. There are restrictions on the number of cancellations, and the rules vary by test center. Frequent cancellations may result in restrictions on making new appointments. To reschedule, you need to wait for the system to release test slots, and popular time slots may require a longer wait. The whole process is quite simple and can be completed in five minutes on your phone.

Canceling the subject one test appointment is quite convenient directly through the 12123 traffic app. After logging into the app, navigate to the exam appointment page, select the record you wish to cancel, and click cancel. Remember to do this at least one day in advance, as the system won't allow cancellations on the exam day. Each cancellation counts as one appointment opportunity, and local DMVs have limits on the number of cancellations. You'll receive an SMS notification upon successful cancellation, at which point you can reschedule the exam. If the system is lagging, try exiting and reopening the app—this usually resolves the issue.

I've canceled my subject one exam appointment twice on the 12123 traffic app, and the steps are quite straightforward. After logging into the app, click on the exam appointment function, locate the corresponding appointment record, and follow the prompts to cancel. The most crucial point is to complete the cancellation at least one day in advance - especially for 3 PM exams, the deadline is usually 4 PM the previous day. It's best to take a screenshot as proof after successful cancellation, which can serve as evidence if there's a system delay in receiving the SMS notification. When rescheduling, you may need to wait two days for the test slot to become available again, so plan your time carefully if you're in a hurry. The entire process doesn't require any fees, which is quite user-friendly.
