What effect will an icy road have on braking distance?

An icy road significantly increases braking distance due to reduced traction between the tires and the surface. When brakes are applied, the vehicle is more likely to skid rather than stop quickly, as the friction is insufficient to decelerate effectively. Consequently, drivers must allow for greater stopping distances in icy conditions to prevent accidents. It's essential to drive at reduced speeds and maintain a safe distance from other vehicles in such conditions.
