As of June 2014, Michigan is one of eight states with a differential speed limit in place on its rural freeways, which sets a maximum speed of 70 mph for passenger vehicles and 60 mph for trucks and buses. In select urban environments, these speed limits are both reduced to a uniform 55 mph limit. Legislation was introduced in early 2014 that proposed increases to these speed limits. In order to ascertain the potential impacts of these proposed speed limit increases, this research examined a…
