Which color line marks the left edge of the roadway?

• A. White line
• B. Dashed yellow line
• C. Yellow line
• D. Dashed white line

Answer: (C)

White lines mark the left edge of the roadway. Edge lines show where the pavement ends and the shoulder begins, and they’re solid white to tell you not to drive onto the shoulder. The other colors indicate different lane and direction rules: yellow lines mark the centerline or no-passing zones on two-way roads, and dashed lines (white or yellow) indicate where crossing a line is allowed when it’s safe. A dashed white line would be used for lane changes, not for marking the road’s edge.
