Which of these locations is it illegal to carry a firearm in Indiana, even with a permit?

In Indiana, it is illegal to carry a firearm on school properties regardless of whether or not you have a permit. This is due to federal and state laws that aim to protect schools and ensure a safe learning environment. The other options, such as public parks, restaurants serving alcohol, and private vehicles, all have certain exceptions or requirements for carrying a firearm with a permit. For example, while it is legal to carry a firearm in a public park with a permit, it may be prohibited in specific areas such as playgrounds or during certain events. Similarly, while carrying a firearm in a restaurant serving alcohol is generally allowed with a permit, it may be restricted in certain establishments or if the person is under the influence of alcohol. Private vehicles also have specific regulations for carrying a firearm, such as storing it in a separate compartment or securing it in a certain manner. However, when it comes to carrying a firearm on school properties in Indiana, it is strictly prohibited and illegal regardless of any other circumstances.
