What does a solid white line along the edge of the roadway indicate?

• A. The boundary of the travel lane; do not cross except to avoid danger or for safety purposes.
• B. It marks the edge of the shoulder and can be crossed anytime.
• C. It indicates a pedestrian crossing zone.
• D. It designates a bike lane only.

Answer: (A)

Solid white edge lines show where the driving surface ends and the shoulder begins. They mark the boundary of the travel path, and you should stay in the lane and on the paved roadway. Crossing the line is only appropriate to avoid a hazard or for safety purposes, not for normal driving. This line isn’t a pedestrian crossing zone and it isn’t indicating a bike lane.
