Will I fail if I drive at 10 km/h in second gear during Subject 3? The relevant introduction to Subject 3 is as follows: Introduction 1: Subject 3 includes the road driving skills test and the safe and civilized driving knowledge test. It is part of the motor vehicle driver's license and is the abbreviation for the road driving skills and safe and civilized driving knowledge test subjects in the motor vehicle driver's examination. The content of the road driving skills test varies depending on the type of vehicle being licensed. Introduction 2: The road driving skills test for Subject 3 generally includes preparation before getting on the car, simulated lighting test, starting, driving straight, shifting gears, changing lanes, parking by the side of the road, 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.

When I was taking my driving test, I was particularly afraid of gear and speed mismatch. The instructor kept reminding me every day not to let the second gear go below 15 km/h. If you drive at 10 km/h in second gear during the test, the tachometer needle will shake noticeably, and the car body will also shake. The examiner will immediately notice that you're lugging the engine. The system will directly deduct 10 points. If you drive like this near an intersection or crosswalk, you might lose another point and fail the test right away. Actually, when the speed drops to 10 km/h, you should shift to first gear, as first gear allows speeds from 0 to 20 km/h. During practice, try more semi-clutch driving in residential areas to get a feel for controlling the speed with the clutch without pressing the accelerator. This way, you can stay calm and steady during the test.

My friend failed the driving test (Subject 3) because of this. During a turn, the speed dropped to 10 km/h while still in second gear, causing the engine to stutter. The examiner immediately marked it as a fail. Later, during remedial lessons at the driving school, we learned that second gear requires maintaining at least 15 km/h. The instructor said the test cars now have GPS speed detection, which is more precise than we thought. If the speed stays below 15 km/h for 5 consecutive seconds, the system will flag it as a gear mismatch. The right approach during traffic jams or turns is to press the clutch and shift to first gear in advance. Before the test, practice uphill sections more to build muscle memory for gear shifting.

Shifting to second gear at 10 km/h is very dangerous during Subject 3 test. Mismatched speed and gear position will cause insufficient engine torque. While severe vehicle shaking is a minor issue, sudden stalling on slopes would be disastrous. I've witnessed examinees stalling before crosswalks and getting immediately failed by the examiner. The ideal speed range for second gear is 20-30 km/h - smooth enough while avoiding gear dragging. Be prepared to downshift when speed drops below 15 km/h. Remember to survey the test route beforehand and identify intersections requiring frequent deceleration.

When reviewing with students, it was found that driving at 10 km/h in second gear most commonly occurs in two scenarios: turning the steering wheel too sharply and forgetting to slow down, or being overly conservative and afraid to press the accelerator when following a car. In fact, reducing to 10 km/h is not as stable as shifting to first gear, which can support speeds as low as 1 km/h. Here’s a tip: when slowing down, press the clutch first, then brake, while keeping your left hand on the gear lever ready to shift. On the test track, start preparing to downshift as soon as you see a zebra crossing. If you hear the engine stuttering, immediately engage the clutch halfway and give a little throttle.

Last week, I specifically tested this while accompanying my cousin during his driving practice. Driving at 10 km/h in second gear caused the engine warning light on the dashboard to flash wildly, and when the RPM dropped to 500, the car shook like sitting on a massage chair. The instructor explained the principle: the second gear ratio design requires a minimum speed of 15 km/h; below this speed, the combustion chamber cannot function properly. Losing points on the test isn't the main issue; the real concern is the increased risk of rolling back or rear-ending. It's recommended to lightly tap the accelerator with your right foot when in second gear to maintain a speed of around 18 km/h for safety. Remember, don't hesitate when starting at a green light—failing to accelerate within 10 seconds will also result in point deductions.
