How many degrees is one full turn of the steering wheel?
2 Answers
One full turn of the steering wheel is 360°, and a quarter turn is 90°. You can think of the steering wheel as a clock. The correct hand position is left hand at the 9 o'clock position and right hand at the 3 o'clock position. To turn 90°, you would turn the wheel one full turn plus an additional quarter turn. Below are some related details about steering wheel operation: 1. Beginners practicing steering don't need to worry about exact degrees turned. Just follow the principle: 'Turn as much as needed, return as much as turned; turn less, return less; turn slowly, return slowly; turn more, return more; turn quickly, return quickly.' The amount of turn can be judged by the steering wheel markings or by observing the direction of the car's front and body. 2. Drive at about 15 km/h on an open road surface while turning the steering wheel left and right to check if it moves smoothly, returns to center properly, and whether the car drifts when you release the wheel.
I've been driving for over twenty years, and turning the steering wheel one full circle is a standard 360 degrees, equivalent to the angle of a full circle. In actual driving, this angle affects the steering sensitivity. Different car models have varying steering ratios. Some sports cars have a lower steering ratio, meaning turning the wheel one full circle allows the wheels to turn more sharply, making the car more agile in turns. In contrast, family cars have a higher steering ratio, so turning the wheel one full circle results in less wheel movement, requiring more turns to achieve the same effect. I remember driving older sedans where a full turn of the wheel was needed to complete a U-turn. Nowadays, with advanced power steering systems in new cars, a single turn can handle the steering, but it's still crucial to remember the wheel's position to avoid locking. Additionally, the centering mark on the steering wheel is very important—after turning, you must check that it returns to the center position; otherwise, the car may drift, affecting driving safety.
