There is no fixed distance for driving straight in Subject 3, but it is generally around 100 meters. The methods to maintain a straight line in Subject 3 are as follows: 1. Choose a fixed reference point: Looking further ahead can help maintain a straight line. You can find a fixed point on the road ahead, which could be an object or a sign, and follow it with your gaze while driving. 2. Maintain a suitable speed: Drive at a constant speed according to local requirements, avoiding significant acceleration or deceleration. 3. Adjust the steering wheel: Remember to make "minor adjustments" only, as the straight driving section is highly sensitive to steering wheel angles. 4. Keep hands and feet relaxed: Arms should be relaxed to control the steering wheel flexibly, and legs should be natural to maintain a constant speed. 5. Be familiar with gear shifting: Memorize the instructor's guidance on "which speed corresponds to which gear." Daily practice should help develop muscle memory so that you can shift gears naturally. 6. Maintain a good mindset: A relaxed mindset leads to flexible hands and feet, and a clear mind enables better performance.

I'm extremely familiar with the straight-line driving section of Subject 3. After years of teaching, I've summarized that the test distance is uniformly set at 100 meters in most regions across the country, with some areas possibly extending it to 120 meters. Remember to maintain a steady speed around 30km/h, and the directional deviation must not exceed 30 centimeters. Many students fail at this point. Actually, the trick is to align with the lane markings in advance before entering the test section. Once you hear the instruction, don't hesitate—keep the throttle steady, focus your eyes on distant buildings, and make only slight adjustments to the steering wheel—never jerk it. Although 100 meters seems short, it feels incredibly long when you're nervous. I always have my students practice over 200 meters to get the feel of it.

Last week, I took students to the test site for a simulation and specifically measured the distance of this exercise: it is exactly 100 meters from the start to the end of the voice prompt. The entire process requires maintaining a stable speed, with only minor adjustments to the direction. Some students asked why they always veer off the line, which is actually related to the bad habit of focusing too much on the distance from the car's front. The correct approach is to look far ahead towards the end of the road and use peripheral vision to glance at the rearview mirror for assistance when feeling the car drift, naturally avoiding swaying left and right. During practice, it's best to find a 200-meter straight road to repeatedly reinforce this skill, making the 100-meter test distance no problem at all.

Strictly speaking, the straight-line driving test distance is exactly 100 meters, requiring the speed to be maintained between 30±5 km/h. The core of this test item is to assess directional perception ability, so steering wheel corrections must be limited to within 3 degrees. From my teaching experience, I've found that students who focus too much on the car body actually struggle to drive straight. It's essential to develop spatial reference awareness. I recommend practicing reference point positioning drills on open roads: for example, fixating on a billboard 200 meters ahead while monitoring lane line distances through rearview mirrors. Once mastered, passing the 100-meter test will become effortless.

The most frustrating part of coaching for six years has been this particular test. Despite being only about 100 meters long, the failure rate among students is extremely high. There are three key points: focus your eyes on a fixed reference point 200 meters ahead, lightly hold the steering wheel without gripping it too tightly, and when you feel the car drifting, make micro-adjustments no wider than the width of your pinky finger. Maintaining a speed of 30 km/h is the most stable—too fast can cause panic, while too slow makes it difficult to stay straight. Some test routes are extended to 120 meters due to special layouts, but the techniques remain the same. I always have my students practice repeatedly on a 120-meter line drawn in the training area, so they can handle the test with ease.
