Final answer:
On a sharp curve, you should use your brakes to slow your vehicle before you enter the curve, not while you're already in the curve. Slowing down before entering the curve allows you to maintain better control of the vehicle and reduces the risk of skidding or sliding.
Step-by-step explanation:
This is because applying the brakes while in the curve can cause the vehicle to lose control due to the lateral forces acting on it. By slowing down before entering the curve, you can maintain better control of the vehicle and reduce the risk of skidding or sliding.
It's important to remember that on a curve, the friction between the tires and the road plays a crucial role in keeping the vehicle on the desired path. If you apply the brakes while in the curve, it can lead to a loss of friction and result in a loss of control. Therefore, it is safer to slow down before entering the curve and then maintain a steady speed throughout the curve.
