Final answer:
To avoid skidding, it is essential to reduce speed before entering a curve, which helps maintain vehicle control under challenging conditions like icy roads.
Step-by-step explanation:
Before entering a curve in order to avoid a skid while driving, one should reduce speed. Reducing speed before the curve is crucial because it helps maintain control of the vehicle and prevents it from skidding or sliding, especially on icy mountain roads where the risk of losing traction is greater. It is important not to apply brakes too sharply, accelerate, or turn the steering wheel sharply while in the curve, as these actions can also lead to loss of control.
