When a road like the one shown is wet, by roughly how much should you lower your speed?
Correct answer: By about one-third.
Answer options
ABy about one-fifth
BBy about one-third Correct
CBy about one-half
Why
On wet pavement, slow down by roughly a third: a truck that would go 45 mph on a dry road should go about 30 mph. On packed snow, cut your speed by half or more.
