What are the three points in curve driving?
4 Answers
The three points in curve driving are when the hood overlaps with the right-side arc, when the left front of the car overlaps with the right-side arc, and when the left front of the car aligns with the left-side arc. When the hood overlaps with the right-side arc: After entering the S-curve, observe carefully. When the hood overlaps with the right-side arc, turn the steering wheel one full turn to the left. When the left front of the car overlaps with the right-side arc: As the vehicle continues to move forward, when the left front of the car overlaps with the right-side arc, turn the steering wheel half a turn to the left, then make slight adjustments to keep the front of the car overlapping with the arc. When the left front of the car aligns with the left-side arc: Before entering the right curve, observe carefully. When the left front of the car aligns with the left-side arc, straighten the steering wheel.
I often drive on mountain roads, and the three key points for curve driving are the turn-in point, the apex, and the exit point. The turn-in point is where you start steering—you need to spot it a bit early and not wait until the curve entrance to turn, otherwise you risk running off the road. The apex is the innermost part of the curve, and keeping the car’s trajectory close to it makes the turn smoother. The exit point is where the curve ends—ensure a steady exit without sudden acceleration. Mastering these three points saves fuel and enhances safety, especially useful for daily driving on mountain roads or in rainy conditions. For practice, find an empty curve and try at low speed a few times to feel the car’s centrifugal force and steering feedback. Don’t overlook these basics—many novice accidents happen due to poor turn-in control. The key is anticipating road conditions early and maintaining moderate speed—slow in, precise at the apex, and steady out—this significantly improves the driving experience.
When I was learning to drive, the instructor always emphasized the three key points of curve driving: the entry point, the apex, and the exit point. The entry point is where you start turning, and it's not good to turn too early or too late. The apex is the deepest part of the curve in the middle, and aligning with it makes the turn easier. The exit point is the end of the curve, and you should straighten out smoothly without rushing. Remembering these helped me avoid mistakes during the test, like turning too wide and scraping the curb. New drivers tend to get nervous, but it gets better with practice. When turning in the city, look ahead at distant road signs in advance, control your speed, and avoid speeding—this ensures safety and peace of mind. The instructor said the trick to mastering these three points is to keep your gaze far ahead and anticipate positions without distraction. I found that with practice, the car feels more stable, and there's less motion sickness.
The key to safe curve driving lies in three points: the entry point, apex, and exit point. The entry point determines the steering timing; the apex is the innermost point of the curve, aligning with it can reduce skidding; the exit point ensures a smooth exit. Mastering these can avoid the risk of losing control, especially during snowy conditions when slow and gentle maneuvers are crucial. Drivers need to observe the curve shape in advance and adjust the entry angle to balance centrifugal force. Experience tells me that neglecting these points easily leads to tail slides or collisions with trees. Maintaining distance and visibility is important—enter gently, apex accurately, and exit smoothly.
