There is a strong relationship between crash severity and location in Minnesota. Fatal crashes generally require high speed and occur in rural areas where there is abundant opportunity for high speed. The congested traffic and the slow speeds of urbanized areas lend themselves to more numerous but less severe crashes. The genius, in terms of safety, of the interstate system is that it divides traffic flow. Fatal crashes make up only one half of one percent of all crashes.
Most crashes are minor and they mostly occur in the urban areas.
