Which line marks the outer edge of the road?

• A. Dashed white lines
• B. Solid yellow lines
• C. Dashed yellow lines
• D. Dashed white lines

Answer: (D)

The line that marks the outer edge of the road is a solid white line along the right edge of the pavement. This edge line shows where the drivable surface ends and helps keep you in your lane, especially when there’s little or no shoulder. Dashed white lines indicate lane separation and that you may pass when safe, while solid yellow lines mark the left edge of the roadway or no-passing zones on two-way streets, and dashed yellow lines mean passing is allowed when safe. So the outer edge is identified by the solid white edge line, not a dashed line.
