Which statement about exit signs visibility during darkness is true?

• A. Exit signs should clearly indicate the location of exits and guide occupants to safety, including in darkness.
• B. Exit signs are optional in many occupancies.
• C. Exit signs must be replaced every year.
• D. Exit signs are only required on exterior walls.

Answer: (A)

The main idea tested is that exit signs must be illuminated and clearly visible in darkness so people can find exits and move to safety during an emergency. In a real incident, power can fail or smoke can obscure visibility, so exit signage needs a reliable light source—often emergency power or battery backup—to stay lit even when normal lighting is out. This is why the correct statement emphasizes that exit signs should clearly indicate the location of exits and guide occupants to safety, including in darkness. Exit signs are a required safety feature, not optional, and their purpose is to help people orient themselves and exit quickly during an emergency. They aren’t something that must be replaced every year, and they aren’t limited to exterior walls alone—signs are placed along interior routes and at exits to ensure a clear path to safety.
