For lane changes in Subject 3 of the driving test, shift to second gear. When the vehicle needs to change lanes, the driver should carefully observe the traffic conditions. Below is an extended explanation: Check rearview mirrors: Before changing lanes, pay attention to the size of the following vehicle in the rearview mirror to estimate the distance. For example, if the following vehicle is a sedan and appears about the size of a matchbox in the rearview mirror, it is typically 80-100 meters away or even farther. If it occupies more than half of the rearview mirror, the distance is much closer (40-50 meters), and the driver should be cautious. Observe traffic signs: When changing lanes at intersections, check road signs and markings in advance. Choose the appropriate lane based on the intended direction and enter the designated lane according to the guiding arrows before reaching the solid line area.

When I first got my driver's license, I also struggled with which gear to use for lane changes in the third road test. After driving in the city for over a decade, I've learned that lane changes should be light, quick, and smooth. At speeds of around 30 to 40 km/h, third gear is most suitable—it provides enough power without being too aggressive. If the test route has low speed limits or heavy traffic, dropping to second gear is fine; taking it slow is safer. Beginners should avoid higher gears—fourth and fifth gears make the car too fast to control direction well. Examiners pay most attention to safety details like signaling and checking mirrors. Just practice a few times to get the feel for it.

The key requirement for the Subject 3 driving test is stability. When changing lanes, I usually instruct students to use second gear. Second gear provides moderate speed that's easier to control. After activating the turn signal, don't rush to turn the steering wheel - first turn your head to check the rearview mirror for any vehicles. Only proceed with a small-angle lane change when it's clear. If encountering a slope or curve during lane change, it's better to brake and downshift to maintain stability. The evaluation system primarily focuses on safety standards. As long as the gear matches the speed range and the engine sound remains stable without jerking, the main deduction points will be on turn signal usage and observation.

During my driving test for Subject 3, the instructor kept nagging about lane change techniques. Most test centers require using second gear for lane changes, with a speed around 30 km/h being the safest. Third gear is too fast and can easily make you nervous. Always observe the road conditions in advance, turn on the signal for three seconds before starting the maneuver. When changing lanes, don’t steer too sharply; a gradual approach is more stable. Be mindful not to press the accelerator too hard, and lightly tap the brake when releasing the clutch for a smoother transition. Only after passing did I realize the key lies in anticipation and staying relaxed.

After driving for decades and teaching my kids to practice the third driving test, I always remind them to use lower gears when changing lanes. Second gear provides enough power and is easier to control. After signaling, check the mirrors and blind spots thoroughly, and only turn the steering wheel when it's safe. A common mistake beginners make is turning too sharply when changing lanes, causing the car to jerk—this will cost points. On test routes, the speed limit is usually below 40 km/h, so third gear is also acceptable for lane changes, but keep the RPM below 2500. Remember to coordinate the accelerator and clutch smoothly to avoid jerky movements.

Vehicle power transmission depends on RPM matching. Selecting second gear for lane changes in Subject 3 is a safe choice. Second gear provides moderate torque around 2000 RPM, ensuring accurate steering direction while maintaining speed control during lane changes. In practice, first stabilize the speed around 25 km/h, lightly press the accelerator to maintain a steady speed, and simultaneously pay attention to road inclines or obstacles. The exam evaluation system monitors operation smoothness, as lane changes in higher gears can easily cause gear dragging and vibration. Focus on developing a habitual action chain: signal - observe - steer - straighten. Mastering this process will make passing the test much easier.
