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

• A. It marks the center of the road and lane boundaries.
• B. It marks the edge of the drivable roadway; crossing it is discouraged except to enter or exit the roadway.
• C. It designates a bike lane only.
• D. It indicates a no-passing zone.

Answer: (B)

A solid white line along the edge marks the boundary of the drivable pavement. It guides you to stay on the roadway and warns that the shoulder beyond it may be soft, uneven, or have hazards. Crossing this line is discouraged because leaving the paved surface can be unsafe; you should cross only when necessary to enter or exit the roadway, such as pulling onto or off the shoulder or into a driveway, and you should do so with extra caution. This line is not the center line and does not designate a bike lane or a no-passing zone.
