Why can't I schedule Subject 4 on the Traffic Management 12123 platform?

The specific reasons why you cannot schedule Subject 4 on the Traffic Management 12123 platform are as follows: Insufficient or invalid training hours: To schedule Subject 4, you must complete 10 training hours, with no more than 4 hours per day. Invalid training hours may occur if you are simultaneously training for other subjects, such as studying Subject 1 theory and Subject 4 theory concurrently, or training for Subject 1 and Subject 2 at the same time. It is recommended not to study different subjects in a single day. Photo discrepancies can also lead to invalid training hours. If the photo taken during training differs significantly from the one submitted during registration due to posture, shooting angle, or makeup, the system may deem the photo invalid. Not meeting the exam cycle requirement: After passing Subject 3, you must wait for one exam cycle before scheduling Subject 4. The length of the exam cycle varies by region due to differences in administrative efficiency, typically around 10 days. The success of scheduling Subject 4 depends on local factors such as the number of applicants, exam capacity, and your position in the registration queue, so there is no precise timeframe for when you can take Subject 4.
I've also encountered the issue of not being able to make an appointment a few times. It's mainly because the system is under maintenance or the server is lagging due to heavy traffic during peak hours. Another common reason is that your subject three test results haven't been synchronized to the backend database yet, so you might need to wait half a day or a day before trying again. Rules vary by region—for example, some cities require you to schedule subject four within seven days of passing subject three, or you'll have to rearrange. I recommend first ensuring your mobile app is up to date and that you have a stable network connection before proceeding. If the problem persists, consider contacting the local DMV or driving school for assistance; they can help check information matching. I've also found that early mornings or weekdays tend to have higher success rates for appointments, while peak times like weekend afternoons are best avoided. In short, don't worry—waiting a bit and retrying usually solves the issue.
