What is a common cause of skidding on icy roads?

Answer: B — Sudden acceleration or braking

Sudden acceleration or braking is a common cause of skidding on icy roads because these actions can quickly disrupt the balance of the vehicle. When a driver accelerates or brakes too abruptly on slippery surfaces, the tires can lose traction with the road. This loss of traction makes it difficult for the driver to maintain control, leading to skidding. Icy roads already reduce the coefficient of friction between the tires and the pavement; therefore, gentle and smooth inputs on the accelerator and brakes are essential for maintaining traction. By avoiding sudden movements, drivers can help ensure that their vehicle remains stable and responsive, reducing the likelihood of skidding in icy conditions.
