Generally, a right turn is a small curve, while a left turn is a large curve. The steering wheel should be turned between 100-130 degrees for a right turn and 130-160 degrees for a left turn, depending on the specific road conditions. Precautions for turning a car are as follows: Pay attention to driving speed: When approaching a turn, the driver should brake in advance to slow down, and then turn the steering wheel at the intersection without rushing to avoid excessive centrifugal force causing the car to skid. If a skid occurs, immediately release the accelerator pedal and turn the steering wheel toward the side of the rear-wheel skid. Once the vehicle resumes straight driving, straighten the steering wheel and continue driving. Pay attention to the turning radius: The driver should accurately estimate the trajectory of the wheels. The degree of steering wheel rotation should correspond to the road curvature and be coordinated with the driving speed. Ensure appropriate steering angle, proper timing for turning, and timely correction of direction. Otherwise, the vehicle may deviate from the intended path and enter the opposite lane, increasing the risk of traffic accidents. Use driving functions correctly: Avoid using neutral gear when entering a curve, especially for U-turns. In neutral, the engine cannot restrain the wheels, causing the car to solely on inertia. In this state, all braking and steering operations become significantly less effective, easily leading to safety hazards.

















When I'm driving, the number of degrees I turn the steering wheel is never a fixed number; it entirely depends on the actual situation. For example, when making a right turn, if the intersection is wide and the speed is slow, I'll turn the wheel about half to one full turn (equivalent to around 120 degrees), ensuring the car smoothly enters the new lane. Left turns are similar, but I'm more cautious about oncoming traffic, usually turning the wheel a bit more, up to one and a half turns (180 degrees), especially on narrow roads. The key is to operate based on vision—once you see the car's front aligned with the direction you want to go, straighten the wheel. Before turning, I always slow down to 20-30 km/h and check blind spots for pedestrians or bicycles. After repeated practice, this becomes muscle memory, and there's no need to calculate degrees; the focus is on safety first, avoiding loss of control due to sharp turns.

I don't think the exact degree of steering wheel rotation should be the focus; turning angles while driving are determined by road conditions. For right turns at large intersections, I steer more gently, around 100-150 degrees is sufficient. Left turns are more complex, such as on city streets, requiring 150-200 degrees to avoid obstacles. But this isn't scientific calculation—it's based on experience: checking mirrors, signaling, then naturally turning the wheel to what feels appropriate. Related points: novice drivers often worry about degrees, but over-focusing on this distracts attention; actual steering is influenced by speed and vehicle type—smaller angles at higher speeds provide more stability. My advice is to first practice fundamentals: slowing down, anticipating, and gradually straightening the wheel to avoid hazards.

When I was learning to drive, I also kept asking this question; a right turn usually requires about 90 degrees of steering wheel rotation to complete, while a left turn needs to be more daring, possibly 120-180 degrees. However, the instructor always said, don't memorize the degrees—how much you turn the steering wheel is visually determined. With practice, you'll understand: quick turns for narrow-angle rights, gentle turns for wide-angle lefts; safety first, I always check the rearview mirror and keep the speed low for every turn.

The vehicle's steering wheel can turn several times (approximately 720 degrees), but only a portion is used for turning. For a right turn, I only need to turn the wheel 100-150 degrees, while a left turn requires about 150-200 degrees, depending on the curve radius and speed. When driving too fast, a smaller steering angle is used to avoid skidding. In reality, drivers adjust the steering intuitively—observing the wheel movement and promptly returning the wheel to the straight position after turning to ensure safe driving.

Once while making a left turn in strong winds, I turned the steering wheel too sharply and the car wobbled, giving me a scare. Since then, I've learned: for right turns, I gently turn the wheel 80-120 degrees, while for left turns it's 120-160 degrees depending on the road width—not precise but guided by feel. The key is to slow down, check blind spots, then begin turning. In rainy conditions, I turn the wheel even more slowly to maintain stability.
