Factors in Collisions

There are a variety of different factors that could contribute to accidents on the roads. Contributing circumstances fall into one of two main categories including vision obscurement and road. Vision obscurement includes weather conditions, physical obstructions, and anything else that could keep a driver from seeing properly out the windshield. Road contributing factors are things such as ice and snow, animals on the road, trees, crops, signs or glare. The most common reported road circumstance was the weather.

Road surface conditions may add to the cause of a crash. Of all fatal reported in 2015, 96 of them were dry pavement.

Driver actions are also responsible for many crashes. In 2015 the most common driver-related contributing circumstances were running off the road, failure to maintain lane, failure to yield, driving too fast for road conditions, tailgating and driving while distracted. These issues and others were determined to have caused or added to a collision according to police and accident reports.
