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

• A. It marks the boundary of the travelled road; do not drive over or onto the shoulder
• B. It marks a bike lane boundary
• C. It indicates a no passing zone
• D. It marks the centerline of the road

Answer: (A)

Solid white edge lines mark the boundary of the paved roadway, showing where the road ends and the shoulder begins. You should stay on the main driving surface and not drive onto or over the shoulder. This helps keep you in a safe, stable lane and avoids hazards on the shoulder, such as soft ground or stopped vehicles. It’s not indicating a bike lane, a no-passing zone, or the road’s centerline—the edge line serves to define the edge of the usable pavement.
