At what speed should you not jerk the steering wheel?

[Terrance]

You should not jerk the steering wheel at a speed of 80 km/h, as sudden steering movements can easily cause the vehicle to roll over. At excessively high speeds, it may even lead to continuous rolling of the vehicle. This is because jerking the steering wheel shifts the vehicle's center of gravity, and in severe cases, it can also result in tire blowouts. Here is a detailed introduction about vehicle speed: Overview: Vehicle speed refers to the distance a car travels per unit of time, commonly measured in kilometers per hour or meters per second. Vehicle speed is one of the three key parameters used to describe traffic flow and holds significant importance in traffic flow theory research. Additional Information: Vehicle speed can also broadly refer to the speed of motor vehicles. To suit different purposes, vehicle speed is mainly categorized into spot speed, segment speed, and design speed. Spot speed is the instantaneous speed of a vehicle passing a specific point on the road. Design speed is the speed set to determine the design parameters of various geometric elements of the road and ensure their coordination.

I remember once driving at 80 km/h on the highway when I suddenly saw a rock ahead. Panicking, I jerked the steering wheel to avoid it, causing the car to swerve and nearly roll over, which scared me so much I broke out in a cold sweat. After that experience, I learned that you shouldn't make sharp turns when driving over 40 km/h because at higher speeds, the inertia is greater, the tires lose grip, and the chassis can suddenly lose control—even the ESP system can't save you in such situations. Now, I always advise my friends: if you encounter danger, it's best to brake first and slow down to below 30 km/h before gently steering. This approach is much more stable—don't expect to safely avoid obstacles by swerving at high speeds. Steering at low speeds is fine, but at high speeds, you must stay steady. Developing this habit ensures safety—after all, safety comes first.

While driving, I once tried jerking the steering wheel sharply at 60 km/h, and the car immediately became unstable. The reason is straightforward: at high speeds, centrifugal force increases significantly, and sudden tire twisting can lead to skidding, which worsens on rainy or slippery roads. Vehicles with a higher center of gravity, like SUVs, are more prone to rollovers, and even sedans can fishtail. I read in a car magazine that tires have strong grip during low-speed turns, but at high speeds, the wheels rotate too quickly, making any sudden turns dangerous. Now, I recommend adjusting the steering gently above 50 km/h, prioritizing obstacle avoidance and slowing down—don’t mimic racing techniques. When driving at high speeds, steer lightly and smoothly, maintain safe distances from vehicles ahead and behind, and prioritize stability above all.

When driving in the city, it's fine to make slight turns at speeds over 30 km/h, but you need to be careful when exceeding 50 km/h. Once, I made a sharp turn at high speed and almost had a scrape, which gave me a real scare. Jerking the steering wheel at high speeds makes the car unstable and prone to accidents. Now, I've developed the habit of turning slowly at any speed and braking first when encountering obstacles before handling them. Safe low-speed turns are key.
