Points will be deducted if the speed remains below 20 km/h in third gear for more than 8 seconds during the Subject 3 test. In Subject 3, the appropriate speed range for third gear is generally between 25 km/h and 35 km/h, with a minimum speed not lower than 20 km/h and a maximum speed not exceeding 40 km/h. If the speed goes beyond these limits, there is a buffer period of 5-8 seconds to adjust the gear. As long as the corresponding speed is restored within the specified time, no points will be deducted. Below is more information about the Subject 3 test: Subject 3: Subject 3, which includes the road driving skills test and the safety and civilized driving knowledge test, is part of the motor vehicle driver's license . It is the abbreviated name for the road driving skills and safety and civilized driving knowledge test in the motor vehicle driver's examination. The content of the road driving skills test varies depending on the type of vehicle license. Subject 3 test content: The road driving skills test for Subject 3 generally includes: preparation for getting on the car, simulated lighting test, starting, driving in a straight line, gear shifting operations, changing lanes, pulling over to park, going straight through intersections, turning left at intersections, turning right at intersections, passing pedestrian crossings, passing school zones, passing bus stops, meeting vehicles, overtaking, making U-turns, and driving at night. The safety and civilized driving knowledge test generally includes: requirements for safe and civilized driving operations, safe driving knowledge under adverse weather and complex road conditions, emergency handling methods for situations such as tire blowouts, and knowledge of handling after traffic accidents.

Last month when I was taking the Driving Test Part 3, the instructor specifically emphasized this key point: if the vehicle speed in third gear drops below 20 km/h and remains so for over 2 seconds, it will be judged as gear disengagement. The examination system automatically detects and deducts points for this. I remember during the road test that day, I momentarily panicked and let the speed drop to around 15 km/h. The dashboard flashed immediately, and the examiner issued a warning. Actually, gear disengagement not only leads to point deductions but can also cause engine strain and vibration, affecting the overall score. I later learned that this rule mainly aims to prevent mechanical wear and safety risks caused by prolonged low-gear high-speed or high-gear low-speed driving. So during practice, I made a conscious effort to control gear-shifting timing, usually downshifting to second gear when speed fell below 25 km/h. I did over ten simulation runs before the test to basically avoid such mistakes. If you're learning to drive, I recommend consulting instructors frequently and familiarizing yourself with the vehicle's power delivery points, as responses vary between car models.

As a veteran driver with over a decade of experience, I've witnessed numerous cases of novice drivers making mistakes during tests. Gear control in Subject 3 is particularly crucial. When in third gear, if the speed drops below 20 km/h, the system is set to deem it non-compliant after just 2 to 3 seconds, resulting in immediate point deductions. The reason is that too low RPM in higher gears can easily cause engine vibration and power interruption, and examiners will check instrument or sensor readings. This isn't just about passing the test—it's a fundamental habit for safe driving. I've seen many drivers on the road staying in high gear for too long, causing the car to jerk and lurch dangerously. During practice, I recommend finding a flat road to repeatedly test, maintaining the speed around 25 km/h within the shifting range to minimize sudden speed drops. If you're nervous on the test day, remember to control the throttle smoothly—avoid overly aggressive acceleration or braking.

During the driving test, the most challenging part of Subject 3 for me was the gear shifting section. According to the standard examination rules, if the speed drops below 20 km/h in third gear for more than 2 consecutive seconds, points will be deducted. Before my test, the instructor demonstrated that it's safer to immediately shift to second gear when the speed drops to 18 km/h. I didn't pay attention that time, and the dashboard alarm sounded, resulting in point deduction. Fortunately, I still passed. I recommend that beginners practice this scenario more with the training car to avoid gear mismatch.

During my driving school training, I always pay attention to safety details. In Subject 3, gear-speed matching is required. If the speed drops below 20 km/h in third gear for about 1.5 to 2 seconds, the exam system will record a penalty. Don't underestimate this brief moment - gear disengagement can cause vehicle instability and increase accident risks. I've experienced several practice sessions where the engine rattled when the speed dropped too low. I remind everyone to thoroughly test the vehicle's performance before the exam and develop the good habit of timely gear shifting to ensure a smoother test experience.

When learning to drive, I focused on mastering skills. Gear 3 speed control in Subject 3 is tricky—if the speed drops below 20 km/h for more than 2 seconds, points are usually deducted. During the test, sensors monitor speed changes; too low can overload the engine. My lesson was to simulate urban driving conditions more often, keeping the speed around 25 km/h for stability. I noted the time threshold during each practice, so it became second nature by the exam.
