What should you do if the roads are icy?

Answer: A — Follow at a slower speed

When driving on icy roads, it is important to follow at a slower speed in order to maintain better control and have a longer reaction time in case of potential hazards. Stopping driving altogether may not always be feasible, and keeping your vehicle at the same speed or increasing it can be dangerous and result in losing control of your vehicle. Therefore, option A is the safest and most appropriate action to take when encountering icy roads.
