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 depicted with a zig-zag line on maps. That jagged pattern is used to represent the tall pylons and long spans of overhead electrical lines, making them stand out from other features. A solid or dashed line by itself is more generic and can indicate roads, boundaries, or routes, while lines labeled as telephone would point to telecom lines rather than power. Dotted lines usually mark trails or uncertain boundaries. The distinctive zig-zag symbol specifically signals overhead electrical transmission lines, which is why it’s the best choice.
