When driving under winter conditions the driver/operator should follow at a greater distance because the distance to stop on snow and ice is increased blank times.

• A. 2 to 5 times
• B. 5 to 10 times
• C. 3 to 15 times
• D. 10 to 20 times

Answer: (C)

Winter surfaces drastically reduce tire grip, so braking distance grows far beyond what you’d expect on dry pavement. That means you must leave a much larger gap to stop safely. The stopping distance on snow and ice can be about three to fifteen times longer than on dry asphalt, depending on speed, road conditions, tire condition, and slope. The lower end covers light snow or gentler conditions at moderate speeds, while the upper end accounts for very icy or packed-snow surfaces and higher speeds. Other ranges are too narrow to account for the variability you can encounter in winter driving. So aiming for a three to fifteen times increase in following distance best reflects the need for extra stopping room in winter.
