What is the minimum height for letters in a notice prohibiting firearms?

• A. One inch
• B. Two inches
• C. Three inches
• D. Four inches

Answer: (A)

Ensuring the notice is readable is the main idea. A minimum letter height of one inch is used because it is large enough to be read from a reasonable distance at typical entry points, making the prohibition actually noticeable to people approaching the area. This size balances visibility with practicality, ensuring the notice serves its purpose without requiring oversized text. Larger letter heights would meet the requirement too, but they’re not the minimum.
