Crashes under **normal conditions** dominate in volume, but adverse conditions show subtle but important differences:

* **Adverse weather** accounts for 345,487 crashes but has *lower fatality rates per crash* (0.030) than clear conditions (0.037).
* Fatal crashes spike in **rain on wet roads** and **fog on dry surfaces**—a dangerous and often underestimated combo.

Top 3 weather × road combinations by fatalities:

1. **No Adverse + Dry:** 59,854 fatalities
2. **Rain + Wet:** 5,767 fatalities
3. **Fog + Dry:** 1,137 fatalities
