When you are going fast, it takes ______ movement of the steering wheel to turn the vehicle.

When you are going fast, it takes ______ movement of the steering wheel to turn the vehicle.

• A. More
• B. Less
• C. Same
• D. Double

Answer: (B)

When speed increases, you don’t need as much steering wheel movement to achieve the same turn rate. In driving dynamics, the turning effect (yaw rate) for a given steering angle grows with speed, so to get a specific rate of turning, the required steering angle actually decreases as speed goes up. Put simply, at higher speeds a smaller steering input can produce the same turn, which is why less movement of the steering wheel is enough to turn the vehicle.
