A line that marks the center of a roadway is called its ________.

• A. Center line
• B. Lane line
• C. Median line
• D. Shoulder line

Answer: (A)

The center line is the line that runs down the middle of a roadway, dividing the lanes for traffic moving in opposite directions. It serves as a reference for drivers and for operators during grading or paving to keep traffic on the correct side and to judge when passing is allowed (dashed) or not (solid). This distinguishes it from a lane line, which marks the edges of individual lanes; a shoulder line, which marks the boundary between the driving surface and the shoulder; and a term like median line, which isn’t the standard label for the road’s center. So the center line correctly identifies the line that marks the roadway’s center.
