In Subject Three, the permissible speed range for third gear is 20-40 km/h. Below are relevant details: Precautions for gear shifting: 1. Never look down at the gear lever: Especially during the 100-meter acceleration and deceleration test where shifting from 1st to 5th gear is required, always keep your eyes on the road ahead. Hold the steering wheel with your left hand and operate the gear lever with your right hand. Never look down at the gear lever while shifting. 2. Avoid incomplete gear engagement and coasting in neutral: When shifting gears, release the accelerator and press the brake. Ensure the brake is fully depressed; if not, it may be difficult to engage the gear. Coasting in neutral will result in point deductions. If the gear is not firmly engaged, a sharp grinding noise may occur. Failing to fully depress the clutch promptly and attempting to re-engage the gear may lead to stalling.

I remember it very clearly when I was taking the driving test. The instructor kept nagging about the third gear speed. When using third gear, the speed should ideally be maintained between 25 to 40 kilometers per hour, not below 20 or exceeding 45, otherwise the system would deduct points directly. Last time, I saw a fellow student in the same car hit 45, and the examiner immediately hit the brakes, resulting in an instant fail. Actually, it's not just about the test; you should also develop good habits when driving normally. When shifting from second to third gear, remember to press the accelerator to around 30 before changing gears to ensure a smooth ride. Speeding or driving too slowly can easily cause the engine to shake, and long-term driving like this can damage the transmission. So, the speed range required in the test really makes sense.

During the practice of Subject 3, the most feared situation is gear-speed mismatch, especially with the critical third gear. My instructor told me the speed must be maintained between 20 and 40 km/h—below 20 is considered low-speed gear blocking, and exceeding 40 is called high-speed low-gear. During my test, I drove steadily at 35 km/h in third gear on a straight road. A reminder: there might be slight regional variations, such as northern areas requiring no less than 25 km/h in winter. It's best to check the local traffic app to confirm the standards before the test. Additionally, third gear is suitable for urban expressways; at 40 km/h, the tachometer reads around 2000 RPM, which is the most fuel-efficient state. If the speed drops below 15 km/h, quickly press the clutch and shift down to second gear, otherwise the engine will sputter and stall.

As a driving school instructor, I emphasize the third gear speed standard every day: maintain 25-40 km/h. Going below 20 km/h will lug the engine and damage the clutch, while exceeding 45 km/h is considered dangerous driving. Here's a tip: when the speedometer hits 30 km/h, shifting to third gear is the safest bet. During tests, when encountering turns or school zones, don't panic and downshift to second gear—just coast through slowly at 30 km/h in third gear. In actual driving, this speed range in third gear is most commonly used, allowing you to overtake bicycles without worrying about speed cameras. If you encounter a long downhill, maintaining 40 km/h in third gear can also utilize engine braking.

The third gear speed must be maintained between 20 and 40 km/h to pass, this data I remember clearly. Having just passed the Subject 3 test, the exam system deducts no points when shifting to third gear at 25 km/h. Two key points to note: first, shift up to third gear as soon as possible after starting, don't linger in second gear; second, don't believe the old drivers' saying 'third gear can go up to 60 km/h'—that's an instant fail. Once during a mock test, I didn't notice the speed dropping to 18 km/h, and the system immediately announced point deduction. I recommend using your phone's navigation during practice, focusing on the speed prompts to build muscle memory. By the way, third gear is more reliable during night tests—maintaining 35 km/h ensures the lights illuminate far ahead and keeps you safe.

The driving theory instructor always emphasizes the gear-speed matching principle. Third gear corresponds to a speed range of 20-40 km/h, which ensures both power and meets environmental requirements. During the exam, going below 20 km/h will be judged as improper operation, while exceeding 40 km/h may trigger a dangerous driving evaluation. In practical operation, referring to the tachometer is more accurate – shifting to third gear between 1500 to 2500 RPM results in the smoothest transition. In actual road conditions during traffic jams, maintaining 25 km/h in third gear avoids frequent gear changes. A common mistake beginners make is shifting up too hastily, engaging third gear before reaching 25 km/h, causing the engine to clunk. Remember to shift only after the speed needle passes 25 km/h for a smooth ride.
