On a wet road, by how much should you generally reduce your speed?
- A.By about 5 mph only
- B.No reduction is needed with good tires
- C.By about one-third
- D.By about three-quarters
Correct answer
C. By about one-third
Why
Wet pavement cuts traction significantly, and the standard guidance is to slow by roughly one-third. On packed snow the cut is half or more, and on ice you should slow to a crawl or stop until conditions improve.
