On a snow-packed road, you should reduce your speed by at least which amount?

• A. At least 1/4
• B. At least 1/2
• C. At least 3/4
• D. None

Answer: (B)

Snow-packed roads dramatically reduce traction, making braking and steering much less predictable. A safe rule of thumb is to slow down by at least half of your normal dry-road speed. This extra reduction gives your tires a better grip, increases your stopping distance, and gives you more time to react to slick spots or sudden hazards. You’ll also want to increase following distance and brake smoothly to avoid skidding. Reducing by only a quarter isn’t enough margin for slick pavement, while reducing by three-quarters would be overly conservative and not necessary in all situations; saying no reduction is required would be unsafe.
