Passing on the right by going over a solid white line that marks the edge of the road is:

• A. Allowed
• B. Not applicable
• C. Prohibited
• D. Permitted in some cases

Answer: (C)

Crossing the solid white line that marks the edge of the road is not allowed when you’re trying to pass. That line defines the boundary between the paved roadway and the shoulder, and it isn’t a driving lane. Using the shoulder to speed past another vehicle can be dangerous because the shoulder is not designed for regular traffic—it may have debris, soft ground, or obstacles, and it can put pedestrians and cyclists at risk.

To pass safely, stay in your driving lane and only pass where permitted, typically in a lane designated for passing or in the left lane when the line markings allow it. The solid edge line is a cue to stay on the roadway and not use the shoulder as a passing lane.
