Which symbol represents a power transmission line on maps?

• A. Zig-zag solid or dash lines
• B. Dash lines, or lines with the word telephone next to it
• C. Solid line
• D. Dotted line

Answer: (A)

Power transmission lines are shown with a zig-zag line on maps. The jagged pattern stands out and visually evokes overhead cables stretched between tall towers across terrain, making it easy to distinguish from roads or rivers. Whether drawn solid or dashed, the distinctive zig-zag cue is the telltale symbol for these high‑voltage lines.

Dash lines with the word “telephone” refer to telephone cables, not power lines. A solid line by itself is more likely to represent roads or boundaries depending on the map, and a dotted line usually marks proposed features or boundaries.
