The only known motor vehicle collision on Mackinac Island occurred on M-185 at the head of the Shepler passenger ferry dock on May 13, 2005, when the island's fire truck slightly damaged the door on the island's ambulance. Both vehicles were responding to a report from the ferryboat that an injured passenger required medical attention. It has been reported that before this incident, it was the only state highway that never had an automobile accident.

A few times a motor vehicle has been allowed to use the road: in 1979, while filming Somewhere in Time, a car was brought on the island for Christopher Reeve's character to drive. The next time that a vehicle was permitted on the island was on July 6, 1998, to commemorate the original ordinance that prohibited cars from Mackinac Island. A 1901 Geneva steam-powered car toured the island and was exhibited in Marquette Park before being towed by horse back to British Landing.

With all the talk we do about driving and cars, perhaps it would be nice to do away with the car for a day and just bike or walk. I'm not the only one who thinks so- in 2008, USA Today named the island one of the "10 great places to get your feet back on the ground" as a car-free destination".

Would you like to experience a car-free road like M-185?
