What percentage of crashes occur on dry roads?

• A. 72%
• B. 81%
• C. 16%
• D. 10%

Answer: (A)

The idea being tested is how crashes break down by road surface condition. The best answer reflects that the majority of crashes happen on dry roads, about 72 percent. This makes sense because dry pavement is the most common driving condition, so most crashes occur under that condition simply due to exposure. Wet, snowy, or icy surfaces are riskier per mile driven, but they occur less often, so their share of total crashes is smaller.

So the 72 percent figure is the largest share and aligns with the idea that the most frequent condition yields the most crashes. The other options either overstate or understate the dry-road share given how common dry conditions are in everyday driving.
