Michigan Compiled Laws, Chapter 691. Judiciary § 691.1583

Sec. 3. An operator shall post a conspicuous notice in a conspicuous place near each entrance to and exit from a bowling center that reads as follows:

“Do not wear bowling shoes outside. Bowling shoes are specialized footwear for indoor use only. Bowling shoes worn outside may be affected by substances or materials including but not limited to snow, ice, rain, moisture, food, or debris that may cause the person wearing the bowling shoes to slip, trip, stumble, or fall on the floor or alley surfaces inside the bowling center. Michigan law makes a bowling center posting this notice immune from liability for such an injury.”.
