The US Department of Transportation’s Bureau of Transportation Statistics has some interesting information on fatal automobile crashes that may challenge some perceptions about driving conditions and the risk for fatal automobile accidents and fatal truck accidents. Saturday is the most dangerous day, followed closely by Sunday. Nighttime and adverse conditions are not as problematic as many think: nearly half of all fatal automobile accidents happened during daylight and almost 90% happened on a clear day without any rain or snow. In fact, fatal accidents during snowy conditions barely account for 2% of all fatal accidents.
