12123 Subject 3 may not be bookable because the booking time has not yet arrived, or there are too many test takers in the local area, resulting in a lower ranking, and you may often be placed at the end of the system queue, thus failing to secure a test spot. The following are the precautions for Subject 3: 1. Vehicle Inspection: As the first minor operation after submitting your ID information, pay attention to the direction of the vehicle inspection and the required operations. After getting out of the passenger seat, the most common issue is closing the car door—always remember to close it. The buttons at the rear and front of the car must be pressed only after hearing the broadcast inside the car before proceeding. 2. Light Operations: The main issue here is test takers answering too quickly. After a light operation is announced, wait until the broadcast is complete before performing the operation. Acting before the broadcast ends will be considered a failure. 3. Turn Signal Details: When changing lanes or starting, you need to operate the turn signals. However, after activating the turn signal, remember to wait three seconds before turning the steering wheel; otherwise, the system will deem it a failure. Some learners may struggle with this point, but paying attention to this detail might help them pass Subject 3 easily.

There are many reasons why you can't book the Subject 3 test on the 12123 platform. Firstly, the system might be too busy. The platform gets crowded when there are many users, especially during peak hours in the morning and evening when slots get snapped up instantly. You should try refreshing at off-peak times. Secondly, personal conditions might be an issue, such as insufficient training hours or incomplete exam records. If the driving school hasn’t uploaded the graduation certificate, the system will block you. Technical glitches are also common, like app updates or unstable networks—sometimes restarting your phone or switching networks helps. I recommend first checking your account status and training progress. If everything is fine, try booking at a different time. Don’t lose heart; many succeed by persistently trying to avoid peak times. Additionally, regional restrictions might affect availability—if there are few test slots nearby, you’ll need to monitor the page more diligently. Planning ahead can be a big help.

How to Deal with Gear Shift Jerk in Manual Transmission?

Methods to prevent gear shift jerk in manual transmission: When lifting the clutch to the semi-engagement point, ensure the engine speed matches or slightly exceeds the clutch disc speed to effectively prevent jerking. Specific methods: 1. Pause briefly when lifting the clutch to the semi-engagement point; 2. Apply slight pressure on the accelerator while lifting the clutch, adding a bit of throttle. As the engine speed continues to drop, lift the clutch slightly earlier—don’t wait until the speed fully drops, or it will lag. A manual transmission, also known as a manual gearbox, requires manually shifting the gear lever to change the gear engagement inside the transmission, altering the gear ratio to achieve speed changes.
