What does a solid white line indicate in terms of lane changes?

• A. You may cross to pass a slower vehicle.
• B. You may change lanes safely at any time.
• C. It marks a temporary lane division.
• D. Do not cross; it marks the edge of the lane or a boundary you should not cross.

Answer: (D)

Solid white lines mark the boundary you should not cross. They indicate the edge of a lane or the edge of the roadway, and you must stay in your lane without crossing that line. Crossing a solid white line to pass or change lanes isn’t allowed; you only change lanes when the line is broken or dashed, or when other markings authorize the maneuver. The other choices imply passing or temporary lane divisions, which a solid white line does not authorize.
