"Officers must be aware of the above exemption for valid CPL holders as many of the citizens who openly carry firearms possess valid CPLs. An individual with a valid CPL may carry a visible firearm in the above listed premises.
A CPL holder is not required by law to carry a pistol concealed. A CPL holder may carry a pistol concealed or visible."
"MCL 28.425o provides that a person with a valid CPL shall not carry a concealed pistol in a pistol-free zone. First offense is a state civil infraction. The following is a list of the premises (excluding parking lots) included in
the statute:
School or school property, except a parent or legal guardian who is dropping off or picking up a child and the pistol is kept in the vehicle
Public or private day care center
Sports arena or stadium
A bar or tavern where sale and consumption of liquor by the glass is the primary source of income (does not apply to owner or employee of the business).
Any property or facility owned or operated by a church, synagogue, mosque, temple, or other place of worship, unless authorized by the presiding official
An entertainment facility that has a seating capacity of 2,500 or more
A hospital
A dormitory or classroom of a community college, college, or university
A casino
Note, the above statute applies to CPL holders carrying a concealed pistol. If the CPL holder is carrying a visible pistol, the statute does not apply. As noted above, the unlawful premises listed in MCL 750.234d do not apply to persons with a valid CPL. Therefore, a person with a valid CPL may carry a visible pistol in the areas described in MCL 28.425o and MCL 750.234d."
I also agree on the wording of "there is not way to "open carry" a pistol in vehicle" It leaves it open for the leo to make his own judgement
