Subject 3 does not have specific speed requirements for straight-line driving. Generally, driving on the road should be within 30km/h, and second gear is appropriate. Specific instructions are as follows: Straight-line driving: When hearing the voice prompt "Please maintain straight-line driving," the examinee should look straight ahead, control the steering wheel with both hands, and keep the vehicle moving in a straight line. It is strictly prohibited to ride or press on the road dividing line. Extended information: The content of Subject 3 test generally includes: preparation before getting on the car, light simulation test, starting, straight-line driving, gear shifting operation, changing lanes, parking by the roadside, going straight through intersections, turning left at intersections, turning right at intersections, passing through pedestrian crossings, passing through school areas, passing through bus stations, meeting vehicles, overtaking, turning around, and night driving. Safe and civilized driving knowledge: 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.

During my driving test for Subject 3, I always used second gear for the straight-line driving section, maintaining a speed of around 20 to 25 km/h, which felt very stable. The examiner emphasized that this speed range is easier to pass because higher gears with faster speeds can cause the car to veer off if the steering wheel isn’t controlled properly, while lower gears may result in loud engine noise or even stalling. I remember when I first started practicing, my coach kept reminding me that shifting to second gear is simple—just lightly press the accelerator and avoid unnecessary maneuvers with third or fourth gears. The key to straight-line driving is to look far ahead, hold the steering wheel with relaxed hands, and avoid gripping it too tightly, as that can easily cause deviation. During the test, I focused on the road conditions and passed smoothly. Later, when discussing with classmates, everyone agreed that second gear has the lowest failure rate. In short, beginners should stick with second gear—it’s safe and efficient, so don’t rush for speed.

From the perspective of driving school instruction, using second gear for straight-line driving is most appropriate, with a speed of around 20 km/h being ideal. I've observed many students—when they shift to third gear and the speed exceeds 30 km/h, beginners tend to get nervous, struggle with steering control, and often lose points from the examiner. The advantage of second gear is the steady engine RPM, smoother acceleration and deceleration, and reduced risk of stalling. During regular practice, I always focus on this point, practicing directional control more instead of just staring at the dashboard. Another detail: avoid frequent gear shifts. Shift to second gear early and maintain steady throttle to keep the car straight without drifting. Additionally, exam rules may vary slightly by region, but second gear is almost universally standard.

I feel that driving in a straight line with second gear is the safest, as the speed is moderate and easy to control. As an ordinary driver, I care more about reducing mistakes—second gear keeps the speed between 20 to 25 km/h, with hands lightly holding the steering wheel and eyes focused straight ahead on the road, allowing timely corrections to direction. Avoid using higher gears, as sudden steering inputs when nervous can cause the car to veer off. During practice, I found that proper throttle control is sufficient, and during the test, the examiner values stability and safety awareness more.

For the straight-line driving section of the driving test (Subject 3), I recommend always using second gear with the speed stabilized around 20 km/h. I remember feeling a bit nervous on the test day, but following the instructor's advice to use second gear, gently pressing the accelerator, and holding the steering wheel naturally made the entire process smooth and successful. Using a higher gear like third might lead to overspeeding or deviation due to the increased speed; while lower gears are more stable, they may cause uneven RPM and potential abnormalities. It's best to practice simulating test conditions frequently during training to get accustomed to the rhythm of second gear and avoid last-minute panic during the actual test.

Having driven for decades, I believe the best way to pass the straight-line driving test in Subject 3 is to use second gear. The car's handling is optimal at speeds between 20 to 25 km/h. Don't underestimate the importance of gear selection—beginners using second gear can reduce steering deviations caused by engine vibrations, requiring only slight adjustments to the steering wheel without excessive force. Once you're more experienced, occasionally using third gear is acceptable, but it comes with higher risks. Remember, the key to passing the test is maintaining a smooth straight line, and second gear makes it easier to achieve that.
