Which of the following is listed as a non-public forum?

• A. Public library
• B. City Park
• C. Museum
• D. Airport terminals

Answer: (D)

Non-public forums are government spaces where speech isn’t treated as freely as in traditional public gathering places; the government can regulate or limit speech there more, as long as the restrictions are reasonable and not aimed at suppressing a particular viewpoint. Airport terminals fit this category because their primary function is to facilitate travel and safety, with controlled access and operations. That means the government may impose rules on signage, solicitation, or demonstrations to keep the space safe and efficient.

Public libraries and city parks are typically traditional public forums or designated public forums where the public is expected to have access for expressive activities, with only reasonable time/place/manner restrictions. Museums, while open to the public, aren’t usually treated the same as non-public forum spaces in the same way as an airport terminal. The key point is that airport terminals are the example that represents a non-public forum.
