Here in Missouri the law states that possession of a firearm, in a vehicle on the premises of places posted, is not prohibited so long as the firearm is not removed from the vehicle or brandished while the vehicle is on the premises. That includes the following full list of places you can't legaly carry in Missouri;
In accordance with Section 571.107 RSMo.
. any police, sheriff, or Highway Patrol office or station without consent
. within 25 feet of any polling place on election day
. adult or juvenile jail or institution
. courthouse or facilities
. any meeting of a government body ( except by a member with a concealed carry endorsement )
. bar without consent ( I was told this just changed to you can carry in a bar )
. airport
. where prohibited by federal law
. schools
. child care facility ( without consent of the manager )
. amusement parks
. any church or place of worship without the permission of the Minister or person representing religious orginazation
. any sports arena or stadium with seating for more than 5,000
. hospitals
. private and public property where posted
The Missouri Highway Patrol's booklet "Missouri Concealed Carry Laws" says you can't carry on private or public property where posted. You can be denied access or removed from the premises if caught. If a police officer is called, upon the first offense, you can be fined up to $100.
If within six months a second offense occurs, you can be fined up to $200 and your permit can be suspended for one year
If within one year of the first offense a third citation is issued for a like offense, you can be fined $500 and your permit revoked. Plus you won't be eligible for a new permit for a period of three years. Same goes for the list of places where carrying is prohibited.
