Effective December 1987 and January 1988, the maximum speed limit on rural limited-access highways in Michigan was raised from 55 mph to 65 mph. The study examined the effects of the raised limit on traffic crashes and crash casualties. A multiple time-series design was used, comparing roads where the speed limit was raised with roads where the limit remained unchanged. Results revealed significant increases in casualties on roads where the speed limit was raised. The increases in crash casualties on 65-mph roads have resulted in 31 additional deaths, 420 serious injuries, and 491 moderate injuries over the 25-month period studied. The societal cost of these casualties is nearly $98 million. No changes in crash casualty figures was found for 55-mph limited-access highways or other roads.
