How is a traffic light malfunction defined?

• A. It is blinking
• B. It doesn't work
• C. It is off
• D. It changes too quickly

Answer: (B)

A traffic light malfunction means the signal isn’t operating as it’s supposed to, failing to perform its normal control function. Saying it doesn’t work captures this broad idea—that the system isn’t delivering the expected traffic control signals. Blinking can be a specific mode the signal goes into under certain conditions (like a service or fault mode in some systems), so it isn’t universally the definition of malfunction. An intersection being off could result from a power outage or other issues, which is a form of not working but is more specific. If the signal changes too quickly, that describes a timing error, not the general state of malfunctioning. So the best answer is that a malfunction is when the traffic light doesn’t work or operate as intended.
