Here are the methods to avoid crossing the line when turning in an S-curve during Subject 2: 1. When entering the curve, position the front of the car in the middle. When the left corner of the car touches the right line, turn the steering wheel left by one and a half turns (45 degrees) and maintain the course. When the left corner of the car touches the left line of the second curve, straighten the steering wheel. When the right corner of the car touches the left line of the second curve, turn the steering wheel right by one and a half turns (45 degrees). Once the car is straight, straighten the steering wheel and slowly exit the S-curve. 2. When navigating the S-curve, it is crucial to control the speed properly. Press the clutch gently to slow down, which increases reaction time. Even if the direction is slightly off, it can be adjusted in time to avoid crossing the line. 3. There are two entry directions: left entry and right entry. For a left entry, keep the vehicle as close to the right line as possible before turning the steering wheel left. For a right entry, do the opposite—keep the vehicle as close to the left line as possible before turning the steering wheel right. This accounts for the inner wheel difference, preventing the rear wheels from crossing the line during the turn.

The S-curve is a mandatory item in Subject 2 of the driving test, and I have three key tips. First, the speed must be slow—keep the clutch steady at around 5 km/h to allow ample time for adjustments. Aligning the car body properly before entering the curve is crucial; the highest point of the steering wheel should align with the centerline of the curve for the safest entry. Steering adjustments should be subtle: for a left curve, keep the left corner of the hood along the outer yellow line, and for a right curve, focus on the right corner following the outer line. If the front of the car crosses the line, immediately turn the steering wheel back half a turn. The side mirrors should stay within 30 cm of the edge line to pass. During practice, don’t just memorize reference points—train yourself to instinctively observe the side mirrors. One of my students overcame line-crossing issues in just two weeks using this method. Before the test, make sure to familiarize yourself with the curve’s arc on the test track.

I've been driving a training car for ten years, and the most common advice I give for S-turns is: Eyes faster than hands! When entering the turn, first look at the distant apex, don't fixate on the front of the car. Keep the speed just slightly faster than walking pace, and don't turn the wheel too sharply—push it gently to follow the curve naturally. For example, in a left turn, keep the car close to the right side when entering, and only make a slight left turn after the left rearview mirror passes the apex. The key is to counter inertia: if you feel the car drifting outward, slightly correct the steering; if it's drifting inward, increase the angle a bit. The rear wheel position is the hardest to master—here's a little trick: lower the window to see the distance between the rear wheel and the boundary line more accurately. Practice 'stopping and starting in a curve' often to improve your control feel.

Here's my summary of tips for nailing the S-curve in one go: 1) Ease off the throttle when entering the curve, 2) Hug the outer lane close to the yellow line, and 3) Adjust steering while monitoring the rearview mirror. During practice, I often crossed lines until realizing reference points vary by individual—adjust your seat height to find your optimal view. Don't haphazardly spin the wheel like kneading dough; follow the 'small frequent corrections' principle: make 10-degree steering adjustments, small in magnitude but frequent. The final curve segment is most hazardous—preemptively steer the opposite way to prevent rear wheels from crossing. Chew gum if nervous during the test; gripping the wheel too tightly increases error risk.
