Which of the following statements regarding runway markings is true?

Runway markings serve a crucial role in aviation by providing necessary operational information that helps pilots safely navigate on and around runways. These markings convey important data, such as the runway’s dimensions, alignment, and which parts of the runway are available for takeoff and landing. They also include designations for taxiways and other operational instructions, which are essential for maintaining safety and efficiency in airport operations.

The other options do not accurately capture the function of runway markings. They are not merely for visual appeal, nor are they solely for informational purposes without operational significance. Furthermore, while some markings might indicate taxi routes, the primary purpose of runway markings is broader—they encompass key operational information essential for effective runway usage.
