Generally, turning the steering wheel one full rotation is sufficient for a standard turn. Below is more information on steering wheel usage: Steering techniques when turning a car: For tight turns at small intersections, it's often necessary to turn the steering wheel one full rotation. If that's not enough, you can adjust by turning a bit more. For easier turns at larger intersections, you can start by turning the steering wheel half a rotation and adjust further if needed. Precautions for steering wheel usage: Drivers should not remove both hands from the steering wheel simultaneously. Avoid placing your left and right hands too close together on the wheel. The amount and speed of steering wheel rotation should match the angle of the turn and the vehicle's speed. Do not grip the steering wheel from the inside. Avoid turning the steering wheel when the car is stationary to prevent damage to the steering system and unnecessary tire wear.

I've been driving ride-hailing for ten years and never needed to calculate steering angles. For left turns in the city, it's roughly a quarter turn (90 degrees) to half a turn (180 degrees), slightly less for right turns, depending on how sharp the curve is. I remember last time driving on an unfamiliar mountain road, encountering a hairpin turn where I had to steer full lock and even pull back half a turn, barely scraping past the guardrail with the car body. Rear-wheel-drive cars require special attention to oversteer; once during rain at a roundabout, I turned too sharply and the rear end swung out. Always check the mirrors before turning—last time I almost hit an electric scooter cutting in. New drivers, remember: let the steering wheel naturally return to center after turning, don't hold it rigidly, or you'll wear out the tires unevenly and regret the repair costs.

Having taught driving school for eight years, I frequently correct students' mistakes in steering. For right-angle turns, start with half a turn of the wheel, and add a quarter turn if it feels insufficient. A 90-degree turn is enough when entering a roundabout, but always watch for vehicles from the left. When making a U-turn, turn the wheel fully, but avoid stationary steering to prevent damage to the steering gear. Nighttime curves are the most challenging to handle. Just last week, a student nearly drove into a ditch on a suburban curve due to insufficient steering, but was saved by promptly adding another half turn. Rearview mirrors are more important than the steering angle, especially when changing lanes—always double-check. Break the habit of looking at the steering wheel; the key is to focus on the lane markings and make minor adjustments.

Driving a Formula car through corners is completely different. For a 90-degree sharp turn, you need to brake early and steer quickly and decisively, usually turning the wheel 180-270 degrees. Never try this with a regular family car! Last time at a track day, I saw a private car trying to imitate racing cornering and ended up straight in the runoff area. The most crucial thing in everyday driving is to slow down before the turn and steer naturally along the curve's arc, gradually straightening the wheel as you accelerate out of the turn. Remember, the more abruptly you turn the wheel, the more likely the tires are to lose grip, especially in rain or snow.
