You must drive on packed snow. How should you change your speed?

  1. Reduce it by about 10 km/h
  2. Reduce it by more than half
  3. Keep it, but use four-wheel drive
  4. Reduce it by about one quarter
Show answer

Correct answer: Reduce it by more than half

Packed snow adds a great risk of skids. Drive much slower than normal, and go at a crawl on ice.
