How to Avoid Crossing the Line in S-Curves?

In Subject 2 of the driving test, the most challenging part of navigating an S-curve is maintaining control without crossing the lines. Simply relying on mnemonics like "turn once, then straighten" makes it difficult to master the technique. Here are the most effective methods to avoid crossing the line in S-curves: 1. Use the car's roof corners to align with the lines: There's a useful mnemonic for S-curves—"left point aligns with the right line, right point aligns with the left line." The left and right points refer to the front corners of the car's roof. When turning in a particular direction, use the corresponding roof corner to follow the opposite side's edge line. 2. Slow down in advance: Before entering the curve, reduce your speed. If you're going too fast, it becomes hard to observe and steer simultaneously, increasing the risk of crossing the line and failing. Additionally, follow the principle of taking the outer line by choosing the path with the largest turning radius. For example, if preparing for a left turn, keep the vehicle to the right side. 3. Steering technique: Starting with a left turn, when the left corner of the car touches the right edge line, turn the steering wheel one full turn to the left, keeping the left corner aligned with the right edge line. This ensures the vehicle stays within the lines.
When navigating S-curves, I prefer to sit upright and look far ahead to better judge the curve's trajectory. Avoid turning the steering wheel too sharply—make slight adjustments instead, like gently twisting a faucet. Keep the speed controlled; I usually use half-clutch to inch forward slowly, ensuring a clear view of the wheel and boundary line in the rearview mirror. For left turns, align your right shoulder with the line and initially turn the wheel 90 degrees, adjusting further if needed. When exiting the curve, pay extra attention to the rear—if the back wheel is about to touch the line, steer slightly in the opposite direction. Sometimes, exiting at a slight angle feels safer. Practice aligning frequently, using the hood's crease as a guide, and over time, your hands will naturally find the right balance.
My driving instructor taught me a trick to imagine myself as an extension of the car's front end. Before entering an S-curve, borrow some space from the opposite direction first—for example, move slightly to the right before the first left turn to leave more room for maneuvering. Use peripheral vision to scan the line instead of staring fixedly at the car's front, which can easily cause visual fatigue. Keep your hand movements smooth, turning the steering wheel naturally along the curve's arc without any pauses. When reaching the apex of the turn, adjust by turning the steering wheel back half a turn to prevent the rear wheels from suddenly fishtailing and crossing the line. The raised position of the wiper aligns very accurately with the line—practice a few times to get the feel. Before the test, use a water bottle as a curb to rehearse a few times for more confidence.
