Subject 4 was automatically cancelled because after passing the Subject 3 road test, the system automatically scheduled the Subject 4 exam for the same day. Therefore, when candidates try to make an appointment, the system will display "duplicate appointment" and automatically cancel it. Introduction to Subject 4: Subject 4, also known as the Subject 4 theoretical test or driver's theory test, is part of the motor vehicle driver's license assessment. After the implementation of "Order No. 139 of the Ministry of Public Security of the People's Republic of China", the Subject 3 test was divided into two parts: in addition to the road test, a safety and civilization knowledge test was added, commonly known as "Subject 4", which assesses "driving ethics". Subject 4 test content: Includes safe and civilized driving operation requirements, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations such as tire blowouts, and post-accident handling knowledge.

I remember once my colleague had their Subject 4 test automatically canceled, mainly due to mismatched registration information, such as entering the wrong ID number or misspelling their name. It could also happen if they scheduled the test but didn't take it within the required time frame, leading the system to automatically cancel it. System upgrades or network failures might also cause cancellations, and I've seen many learners share similar experiences on community forums. Additionally, if you've failed the test too many times before, some places will automatically suspend your scheduling, requiring a review of your materials again. I think if this happens, don't panic—quickly check your status on the traffic management app or contact the driving school to confirm, and double-check your personal information to avoid recurring issues. The safe driving test is not something to take lightly, and handling it promptly won't delay getting your license.

Last time when I helped a friend with the cancellation of Subject 4, I found that the common reasons were time-related factors. For example, forgetting the exam date after booking, which leads to automatic cancellation by the system on the scheduled day; or clicking to book but failing to confirm and pay the fee, making it invalid after a few minutes. Additionally, the exam system frequently updates, and using an outdated app version can easily cause bugs leading to automatic cancellation. I recommend taking a screenshot of the notification after each booking to ensure you receive reminder texts or emails on your phone. When operating the app, make sure you have a good signal and avoid making mistakes while filling out forms. If it happens, just book again—after all, Subject 4 content isn’t hard to prepare for. Don’t panic; most issues are minor technical glitches that can be fixed promptly.

The automatic cancellation of Subject 4 may be caused by several common issues. Incorrect information input is critical, as entering the wrong ID number can lead to system rejection. Time conflicts will prompt the system to prioritize canceling overlapping appointments. Identity verification failures are also frequent, often due to blurry photos or failure to upload required documents. It's important to promptly update the app and personal information to avoid affecting appointments. As long as the operation process is clear, there shouldn't be major issues.

What is the reason for the dim headlights of Qin Pro?

The reason for the dim headlights of Qin Pro is that the outer shell of the headlights, after prolonged exposure to wind and sun, can be gradually corroded and scratched by dust and impurities in the air, resulting in a difficult-to-clean yellow stain that causes the headlights to appear dull and hazy. Methods to clean the headlights: 1. Soapy water is a weakly alkaline substance, non-corrosive, gentle in nature, and has strong cleaning power. Simply apply the prepared soap solution to the surface of the headlights, wait for about ten minutes, and then repeatedly wipe with a sponge to remove stains, also providing a certain polishing effect. 2. Use a soft cloth to wipe the surface of the headlights, which can prevent the formation of stains and maintain the brightness of the headlights. During the wiping process, avoid using rough cloths or applying excessive force, as the headlight shell can be scratched. Once scratches appear, stains can get trapped inside, making them difficult to clean.
