The responsibility for the establishment of speed limits on our county roads and roadways, lies with the Michigan State Police, the Jackson County Department of Transportation, and Township Boards, as specifically outlined in the Michigan Vehicle Code. This requires a unanimous determination.

Criteria and standards of normal conditions have been developed to determine what is to be considered the proper speed limit for a section of road. Traffic volume, daylight visibility hours, and dry pavement conditions are all considered when determining an appropriate speed limit. Specific speed limits are based on a traffic study that includes the speeds drivers are traveling on the road, accident patterns and history, the road’s physical characteristics, and surrounding land use.

Please call our office at 517-788-4230, or email us for any specific speed limit requests.
