Which statement about accelerating on a curve is true?

• A. Accelerate before entering the curve
• B. Accelerate after clearing the curve
• C. Accelerate at any point in the curve
• D. Accelerate at the apex of the curve

Answer: (D)

Controlling speed through a curve requires balancing braking, steering, and acceleration to stay within tire grip. You brake before the curve to reduce speed so you can follow the path without sliding. The optimal time to start adding power is at the apex—the point where your car is closest to the inside of the turn. Accelerating there lets you begin to unwind the steering and increase momentum as you transition to the straight, giving you the fastest exit without losing control. Accelerating earlier increases lateral load while you're still steeply turning, which can exceed grip; waiting until after the arc wastes the opportunity to gain speed where you can do so most effectively.
