Why can't I schedule the subject four test after taking subject three before subject two?

Why can't I schedule the subject four test after taking subject three before subject two? It might be because the previous test results haven't been uploaded to the system yet. Here is a brief introduction about subject three: 1. Basic information: Subject three includes road driving skills test and safety civilized driving knowledge test. It is part of the motor vehicle driver's license assessment, and is the abbreviation for the road driving skills and safety civilized driving knowledge test subjects in the motor vehicle driver's test. The content of the road driving skills test varies depending on the type of vehicle. 2. Test content: The road driving skills test of subject three generally includes preparation before getting on the car, light simulation test, starting, driving in a straight line, shifting gears, changing lanes, parking on the side, going straight through intersections, turning left at intersections, turning right at intersections, passing pedestrian crossings, passing school areas, passing bus stations, meeting cars, overtaking, turning around, driving at night, etc.

I have a relative who works at a driving school, and he told me that the inability to schedule the Subject 4 exam is usually related to score synchronization. Normally, you should be able to book Subject 4 after passing Subject 3, but if you took Subject 3 before Subject 2, the system might show that your Subject 2 scores haven't been archived yet. The driving exam system takes 1-3 working days to process scores, especially slower over weekends. I suggest you open the Traffic Management 12123 APP and check the exam scheduling page to see if there are any red-text notifications. If it shows Subject 2 as incomplete, don't worry—just refresh the page a few times tomorrow or the day after. Another possibility is insufficient course hours. New regulations now require completing all video course hours for Subject 4 before scheduling. Ask your instructor to check the course records in the driving school's system. If all else fails, bring your ID to the DMV counter—they can refresh your system status on the spot.

Last time when my brother took the driving test, he encountered the same situation. The instructor explained that there is a delay in uploading the exam system data. It takes time for the signed confirmation data from the Subject 2 test site to be transmitted to the DMV server, and during this processing period, you cannot schedule Subject 4. Especially on rainy days, the slow internet speed at the test site can cause even longer delays in score synchronization. Have you passed Subject 2? If you just finished it, wait 48 hours and try again. Also, check if all the exam fees have been paid—some places require all fees to be settled before opening the Subject 4 scheduling channel. The status 'Ready for Exam' on the mobile app indicates it’s effective; once you see this prompt, scheduling is usually successful. Currently, the DMV system upgrades often have minor bugs, so if it doesn’t work, try using the self-service kiosk at the DMV.

This situation is quite common in driving test groups. The system has a score confirmation process, and reversing the order of subject two and subject three exams may cause data issues. First, check if there's exam qualification info in the 12123 app—if not, the data hasn't synced properly. The solution I've used is simple: refresh the app twice daily (morning and evening) for three consecutive days, and suddenly you can book when the system stabilizes. Another possibility is an issue with your file status—some test centers have slow paper file archiving, which affects the electronic system. Or maybe you passed subject one too long ago, exceeding the three-year validity period, causing the system to lock automatically. I recommend directly asking the driving school's file administrator—having them manually push a data update is much faster than waiting.
