If orange flags indicate underground infrastructure, what type of cable is most likely present?

• A. Fiber-optic communications cable
• B. Gas line
• C. Electrical power line
• D. Water line

Answer: (A)

When you see orange flags marking underground lines, it’s signaling a fiber-optic communications cable. Fiber optics carry data for internet, phone, and network services, so identifying this cable helps you plan digging to protect it from damage and avoid service disruption. Other buried utilities are indicated by different colors: electric power lines are usually marked in red, gas lines in yellow, and water lines in blue. Knowing this helps you interpret marks quickly and coordinate with the right crews before you dig, often by calling a locator service (like 811) to confirm exact locations.
