What should you not do when driving in icy conditions?

Answer: A — Make quick steering wheel turns

Driving in icy conditions requires additional caution to avoid accidents. One of the worst things you can do is make quick steering wheel turns, Option A. This can cause you to lose control of your vehicle and result in a crash. Options B and C are actually safe practices for driving in icy conditions. Option B, allowing plenty of time to stop, is important because it takes longer to stop on icy roads. Option C, using the highest gear, can help prevent your wheels from spinning on the slick surface. Option D, following other vehicles closely, is also incorrect because it reduces your ability to react to potential hazards and can lead to chain-reaction collisions. Therefore, option A, making quick steering wheel turns, is the most dangerous action you can take when driving in icy conditions.
