The reasons for being unable to schedule Subject 3 on the Traffic Management 12123 platform are as follows: 1. Ranking exceeds available slots: If your scheduling rank exceeds the test center's capacity, the chance of successful scheduling is extremely low unless some candidates cancel their appointments. 2. Multiple cancellations: Note that there are limits on cancellation times for each subject. Frequent cancellations may negatively impact your next scheduling attempt. 3. Incomplete training hours: Scheduling will fail if required Subject 3 training hours aren't completed. Typically, Subject 3 requires 16 hours of theoretical training and 24 hours of practical training, with slight regional variations - please refer to local standards. 4. Exam cheating: Candidates who had scores canceled due to cheating must wait one year before rescheduling, during which any scheduling attempts will fail.

I also experienced the frustration of not being able to book Subject 3 on the 12123 app, mainly because the app gets too crowded during peak hours, and the system lags when too many people log in. I remember when I was taking my driver's license test, my coach reminded me to avoid the peak hours around 7-8 PM and instead try refreshing the page early in the morning or on weekday mornings for a higher success rate. Limited slots are also a key issue—each test center releases only a small number of slots per week, so if you're slow, you'll miss out. Additionally, checking personal information is crucial. If your ID number or photo is incorrect, the system will automatically reject your application, and you'll need to verify the details at the driving school. Driving safety is a big deal, so don’t get too anxious if you can’t book a slot right away. Use the time to practice road rules more, which will be very helpful for preventing accidents when you eventually hit the road. In short, keep trying, don’t give up, and remember that mastering the skills safely is the ultimate goal.

It's common to encounter difficulties when scheduling Subject 3 of the driving test. I believe the congestion on the 12123 app is the main reason. The app has a massive user base, making it prone to crashes or errors during peak hours. I recommend refreshing the app regularly, not just rushing when test slots are released. Double-check your personal information, as the system won't allow scheduling Subject 3 if you haven't passed Subject 2. Technical issues like excessive cache can also interfere—clearing the cache or updating the app version usually helps. As an automotive knowledge sharer, I emphasize that scheduling problems are minor; what truly matters is learning safe driving. Spend more time studying traffic signs and the principles of braking systems for a more confident driving experience in the future.

I also tried to book the Subject 3 test on 12123 but failed, which was really frustrating. Most of the time, the system is too busy, and after entering the information, it just spins without any response. Check your network and phone settings; if WiFi doesn’t work, switch to mobile data. The slots are limited, so act early and don’t wait until the last minute. If your personal photo is blurry, you’ll need to re-upload it. During the driving test process, focus on learning the rules, such as lane changing and parking. Use the gaps when you can’t book the test to practice these skills, which will help you pass on the first try. Mastering the basics of driving will make everything go smoother.

Thinking back to when I was taking my driver's license test, the 12123 system often got stuck when scheduling the Subject 3 exam. During peak hours, the system was crowded with people queuing, and waiting for a long time yielded no results. Sometimes it was due to mismatched information, like outdated license photos that needed retaking. With limited slots available, it's advisable to consult the driving school instructor for help in securing a spot. Driving skills are the core; I recommend reviewing Subject 3 content such as turning and following distance when unable to schedule the test, to avoid potential hazards during actual driving. Car knowledge, like regular checks, can also be applied to the driving test.
