Question

Explanation:

On icy roads, the friction between the tires and the road surface is reduced. Stopping distance is related to the ability of the vehicle to decelerate, which is affected by the road - tire friction. Sanity is a psychological state not directly related to driving on icy roads in a mechanical sense. The ability to shift gears is a function of the vehicle's transmission system (for manual cars) which is not directly affected by the road surface being icy. The ability to use headlights is an electrical and mechanical function of the vehicle's lighting system, not related to the road conditions.

your stopping distance
