From this plot, we can conclude that most of the accidents took place in the temperature range of 50 to 80 Fahrenheit. It means that the temperature is very normal. Hence temperature is not very crucial factor in accidents
The plot shows the percentage of accidents in each timezone. Eastern time zone having the highest number of accidents around 43% than pacific, central, and Mountain time zone.
A good proportion of very severe accidents tend to occur at low visibility conditions, although less in number.
Most of the accidents recorded when the wind speed is zero, so we can infer that wind speed is not a crucial factor.
