You will fail if the speed drops below 10 in second gear during Subject 3. The speed range for second gear is 10-30 km/h. When the speed falls below 10 km/h, the engine is prone to stalling. Here is some additional information: 1. First gear: Engine speed around 1000-1500 rpm, vehicle speed 10 km/h, it is recommended to shift to second gear. 2. Second gear: Engine speed around 1500-2000 rpm, vehicle speed 30 km/h, it is recommended to shift to third gear. 3. Third gear: Engine speed around 1500-2000 rpm, vehicle speed 40 km/h, it is recommended to shift to fourth gear. 4. Fourth gear: Engine speed around 1500-2000 rpm, vehicle speed 50-70 km/h, it is recommended to shift to fifth gear. 5. Fifth gear: Engine speed around 1500-3000 rpm, vehicle speed 80-120 km/h.

As a seasoned driver with over 20 years of experience, I always remind young learners during their Category 3 test never to let the speed drop below 10 km/h in second gear, or the risk of failing is extremely high. During the manual transmission test, if the speed is too low (e.g., below 10 km/h), the car will noticeably shake or even stall, leading the examiner to deduct points or declare failure due to unstable operation. The Category 3 test evaluates safe driving skills, and mismatched speed and gear is considered a serious mistake. In real traffic, driving too slowly also increases the risk of rear-end collisions. I recommend maintaining a speed of 15-25 km/h in second gear during practice, with gentle and steady throttle control. Failing the test means wasting time and money on retakes—it’s much better to practice simulated exam scenarios thoroughly beforehand.

I just passed the Subject 3 test not long ago, and I remember clearly that the instructor said failing to maintain second gear speed above 10km/h would definitely result in failure. On the exam day during my urban road test with a manual transmission car, the moment the speedometer dropped to 9km/h, the car started shaking and the examiner immediately marked me as unqualified. My classmate had to retake the test once because of this, wasting a lot of money unnecessarily. Subject 3 emphasizes gear-speed matching for safety, and idling speed driving is considered an operational error with heavy penalties, easily raising the examiner's suspicion of poor control. While second-gear low-speed driving might be acceptable in daily driving, the exam requires maintaining at least 15km/h for safety. During the stressful test, you must constantly monitor the speedometer and not be careless. Practicing fundamentals well makes passing easier.

I've been working in the repair shop for ten years, and common engine issues include stalling and shaking during the Subject 3 test when driving in second gear below 10 km/h due to excessively low RPM, which can lead to failing the test. Driving at too low a speed in a high gear damages the clutch, and the examiner may penalize you for improper operation with significant point deductions. It's recommended to maintain a speed above 15 km/h in second gear during the test to avoid danger, and practice paying attention to pedal feel.

Watching my neighbor take the driving test, my son failed three times before realizing the details: in Subject 3, if the speed in second gear drops below 10 km/h, it's an automatic fail. The examiner deducts points strictly. Failing means spending thousands more to relearn and wasting time. My advice to learners: focus on keeping the speedometer above 15 for safety and control, pass in one go to save money.
