How much is a 90-degree turn of the steering wheel?

[StSawyer]

A 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 way to hold the steering wheel is to place your left hand near the 9 o'clock position and your right hand near the 3 o'clock position. If you want to turn the wheel by 90°, you should turn it a full rotation and then an additional quarter turn. Here are some related tips for beginners: When practicing steering, beginners don't need to worry about exactly how many degrees they're turning the wheel. Just follow the principle of 'turn as much as you need to return, turn less if you need to return less, turn slowly if you need to return slowly, turn more if you need to return more, and turn quickly if you need to return quickly.' As for how much to turn, you can judge by the markings on the steering wheel or simply adjust based on the direction of the car's front and body.
