Subject Three straight-line driving allows slight steering wheel movement. Subject Three is part of the motor vehicle driver's license , abbreviated as the road driving skills and safe civilized driving knowledge test. The road driving skills test generally includes: vehicle preparation, light simulation test, starting, straight-line driving, gear shifting operations, lane changing, parking by the roadside, going straight through intersections, turning at intersections, meeting vehicles, overtaking, U-turns, night driving, etc. Different test contents apply to different permitted driving models. The safe civilized driving knowledge test generally includes: safe civilized driving operation requirements, safe driving knowledge under adverse weather and complex road conditions, and post-traffic accident handling knowledge.

During the straight-line driving section of the road test (Subject 3), slight steering wheel adjustments are allowed, but the movements must be extremely restrained. I remember my driving instructor repeatedly emphasizing during practice: hold the steering wheel lightly with both hands, and focus your gaze far ahead at least 100 meters. When the car shows signs of drifting, just apply slight finger pressure to correct it—the adjustment must never exceed half a palm's width. The key is to detect and correct early; don't wait until the car has visibly deviated before making sharp turns. It's especially important to straighten the car before entering the assessed section. Some students, due to nervousness, gripped the wheel too tightly without any movement, and ended up being flagged by the system for deviation due to uneven road surfaces. Remember, this test evaluates your ability to make micro-adjustments, not to remain rigid like a wooden figure.

Maintaining a straight line doesn't mean keeping the steering wheel completely still, but rather testing steady control. When accompanying family members during driving practice, I've observed that minor adjustments within 5 degrees are allowed. For specific operations, it's recommended to use the 3 o'clock and 9 o'clock hand positions with arms naturally relaxed. The correction principle is to make small adjustments frequently, returning to center after each correction. For example, if the car drifts slightly right, gently push the wheel left with your left hand no more than a fingernail's width, then release immediately when the car straightens. Pay special attention to concrete road joints or sloped sections where natural drifting is common - focusing on distant fixed reference points makes directional judgment easier. Gripping the wheel too tightly actually increases wobbling; treating it with smartphone-screen-like gentle touches is safest.

Personal experience tells you: You must move the steering wheel! During the test, I encountered an asphalt road repair area, and the wheels were pulled to the right by the road surface. At that time, my left little finger pushed about the thickness of a coin, and the car body just returned to the center line and immediately stabilized. Remember two key points: the correction amount should not exceed 5 degrees, which is equivalent to the steering wheel logo moving half a finger width; the second is that after each correction, the steering wheel must be allowed to automatically return to its original position, and continuous left and right shaking is prohibited. During practice, find some straight roads with slight slopes to feel the directional compensation of the wheels. The test system judges based on the displacement amplitude of the car body. As long as the total offset within 30 meters does not exceed 30 centimeters, you can pass.

The core of driving straight is maintaining dynamic balance. Control the steering wheel like holding a bowl of water: gently turn the rim when the water tilts, and stop when it levels out. Common mistakes in the test include students panicking and making large adjustments after noticing deviation, or gripping the wheel too tightly for too long, causing muscle stiffness. My advice is to align the car body before starting the exercise, and while driving, use peripheral vision to observe the dynamic relationship between the lane markings and the front of the car. If the left corner of the car moves farther from the left line, make a slight 5-degree adjustment, as gentle as turning a doorknob. Pay extra attention in rainy conditions—on slippery roads, initiate steering corrections half a second earlier than usual and reduce the adjustment range by one-third. After making an adjustment, count to three seconds to observe the effect, avoiding overcorrection.

Last year, while instructing students for the Driving Test Part 3, I paid special attention to this detail. The steering wheel of the test car is highly sensitive, allowing for micro-adjustments of no more than 1 cm on the plane. The correct method is to imagine the steering wheel as a clock face, with both hands fixed at the 3 and 9 o'clock positions. When you feel the right wheel pressing against the vibrating marking line, use the hypothenar of your left hand to gently push the hour hand from the 9 o'clock to the 10 o'clock direction (an actual movement of about 3 degrees), hold for 2 seconds, and then naturally release to reset. The key is to anticipate the road's trend: when going uphill, the car tends to drift toward the shoulder, so you should retract your left hand in advance; the opposite applies when going downhill. During the test, if there is continuous deviation, you can adjust a maximum of 3 times. After each correction, you must maintain straight-line driving for more than 3 seconds to be considered effective control.
