Why can't I schedule Subject 4 on 12123 and it shows Subject 3 instead?

Subject 4 scheduling requires passing Subject 3 first. Here is more information about Subject 3: 1. Subject 3 includes the road driving skills test and the safe and civilized driving knowledge test, where the latter is commonly referred to as Subject 4 by students and driving schools. However, the official term is the Subject 3 Safe and Civilized Driving Knowledge Test, so seeing Subject 3 when scheduling Subject 4 is normal. 2. The Subject 3 Safe and Civilized Driving Knowledge Test covers: safe and civilized driving operation requirements, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations like tire blowouts, and post-accident disposal knowledge.
I recently just got my driver's license and encountered similar issues when scheduling the subject four test. The 12123 system kept reverting back to the subject three interface, which was quite frustrating. The main reason might be that the scores haven’t been fully uploaded yet, as the data from subject three needs time to sync to the central database, and delays of a day or two are normal. My experience is not to rush to click the scheduling button; first, check in the ‘My Test Scores’ section of the app to see if subject three shows as passed. If it does, wait patiently for 24 hours before trying again. If it hasn’t passed or shows as pending review, you’ll need to contact the driving school to help expedite the upload. The platform’s rules are strict like this, ensuring a step-by-step and orderly process to maintain fairness and safety in the exams. Remember not to repeatedly operate the system to avoid it freezing up. If all else fails, try logging in via the web version on a different device. Though this small issue is annoying, handling it properly will help you get your license sooner and hit the road.
From a technical perspective, the 12123 platform has automated verification mechanisms during user operations. When you schedule Subject 4 but see content related to Subject 3, it usually means the system detects that Subject 3 status is incomplete or data hasn't been updated. Possible reasons include: delayed upload of post-exam results (typically requiring 1-3 working days), App cache issues, or unstable network connections causing incomplete data retrieval. We recommend first checking your personal exam records to confirm Subject 3 passing status; if normal but still stuck, try clearing the App cache or logging out and back in. If errors persist, there might be temporary server-side issues—contact your local DMV hotline for resolution. This logic design ensures standardized exam procedures, preventing skipped steps that could compromise driving safety, so just patiently follow the system rules to resolve it.
