Which statement about exit signage visibility is true?

• A. Directional exit signs are to be used when exit doors are not readily visible.
• B. Signs are optional if doors are clear.
• C. Signs are required only on exterior doors.
• D. Signs are never required.

Answer: (A)

Clear, visible exit signage is about guiding people to a safe egress path during an emergency. When the route to an exit isn’t clearly obvious—such as corridors with multiple doors or turns—directional exit signs are required to point the way. That ensures occupants can find the exit quickly even in smoke or low visibility, which is why the statement about using directional exit signs when exit doors aren’t readily visible is the correct one.

Signs aren’t optional just because doors are easy to see; the presence of signs helps ensure a reliable path to safety in all conditions. Also, exit signage isn’t limited to exterior doors—interior exits and paths leading to exterior doors typically require signs too. And of course, signage isn’t something that would be never required.
