Here's a breakdown:
* Clear weather: Accounts for the majority of crashes, simply because people drive more often in good weather.
* Rainy weather: While rain increases the risk of accidents due to reduced visibility and slippery roads, the overall number of collisions tends to be lower because people drive less often in the rain.
* Snowy/Icy weather: These conditions drastically reduce the number of vehicles on the road, but the accidents that do occur are often more severe.
* Foggy weather: Fog significantly reduces visibility, leading to a higher risk of collisions.
Other factors that contribute to collisions:
* Time of day: Traffic volume is higher during rush hour, leading to an increased risk of collisions.
* Day of the week: Weekends tend to have more collisions due to recreational driving and increased traffic.
* Road conditions: Poorly maintained roads, construction zones, and road hazards all increase the risk of accidents.
It's important to remember that any type of weather can contribute to collisions, but clear weather sees the highest overall number due to the sheer volume of traffic on the road.
