After passing Subject 4, you cannot directly check your driver's license information. You need to wait for one to two working days before you can check the relevant information of your motor vehicle driver's license online. However, this does not affect your ability to drive, as you can legally drive after passing Subject 4 and receiving your motor vehicle driver's license. Applicants for a motor vehicle driver's license must pass the following four subjects: Subject 1 (Road Traffic Safety Laws, Regulations, and Related Knowledge), Subject 2 (Field Driving Skills), Subject 3 (Road Driving Skills), and Subject 4 (Safe and Civilized Driving Knowledge). The exams must be taken in the order of Subject 1, Subject 2, Subject 3, and Subject 4. Only after passing the previous subject can you proceed to the next one. Subject 4, also known as the theoretical exam or driver's theoretical exam, is part of the motor vehicle driver's license . The main content includes: safe and civilized driving requirements, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations like tire blowouts, and post-accident handling knowledge. The passing score for Subject 4 is 90 out of 100. The exam consists of 50 questions, each worth 2 points, with a total duration of 45 minutes. If you answer six questions incorrectly, the exam will automatically be marked as failed. If you answer 45 questions correctly, the exam will be marked as passed. There is no limit to the number of attempts for Subject 4, but there is a time limit. If you fail to pass Subject 4 within the three-year validity period, the results of other subjects will become invalid, and you will not be able to continue the driver's license exam process.

Right after I passed the DMV written test (Subject 4), I was so excited that I immediately checked my driver's license info on the 12123 traffic app, only to find the system hadn't updated yet—it showed 'under review.' After asking around, I learned the backend processing takes 1-3 business days. Examiners need to input scores into the public traffic system, verify personal details and test results before generating the e-license or mailing the physical copy. So even if you ace Subject 4, don’t rush—give it time. I got my SMS notification days later. The wait can be annoying; my advice is to either wait patiently or visit the DMV counter directly instead of pointlessly refreshing the app. Safety first: never drive before physically holding your license to avoid trouble. Bottom line—patience pays off.

After passing Subject 4, I also tried checking my driver's license status, but there was no update at all. The reason is system delay: Subject 4 scores need to be uploaded to the public database, undergo review and synchronization before generating the electronic driver's license record or mailing the physical card. It usually takes one or two days, or even three to five days during peak periods. My advice is to avoid unnecessary operations and wait quietly for the notification SMS or check status changes in the APP. If you're in urgent need, bring your ID card to the local DMV for on-site inquiry—they can confirm instantly. Remember, don't get too excited and drive immediately after passing the test. Wait until you have the license in hand before hitting the road—that's the smart choice. Safe driving starts with small details. Don't make the same mistake as I did by waiting foolishly; make better use of official resources.

After the subject four exam, I've been through checking the driver's license. Don't expect to see it immediately because there's a delay in score entry and approval procedures. System synchronization usually takes a few days. Use the Traffic 12123 app or official website to check the progress. If it shows 'Accepted' or 'Pending Mailing', just be patient, it will update within a day or two. Avoid refreshing too frequently to prevent errors. If you're really in a hurry, contact the vehicle management office directly for assistance. This is different from checking regular exam results - driver's license generation involves personal information security verification, so more careful processing is essential.

Just passed Subject 4, my experience checking the driver's license was simple: don't rush to refresh the app. The system requires backend processing time. The Subject 4 results need to be uploaded and verified before the electronic or physical version of the license can be generated. It's recommended to wait 24 to 48 hours before checking, usually through the 12123 service to view the status. If there's no update, it might be due to data delays or holiday backlogs. Visiting the DMV in person is the most straightforward solution. Safe driving starts with the license—don't drive impulsively to avoid violations and regrets. Be patient; the license will arrive on time.

After passing Subject 4, I was excited to check my driver's license but found the app empty. Turns out backend processing isn't that fast: examiners submitting scores, database verification, and system-generated licenses all require buffer time, averaging about a day. I later saw my status change from 'Under Review' to 'License Issued' on the 12123 platform before feeling relieved. My advice: don't rush to check, use the waiting time to review traffic rules and prepare for safe driving once you get your license. If truly concerned, call the DMV hotline to inquire about progress—it beats unnecessary hassle.
