Official Driving School Segment 1 Practice Test

Crossing the solid white line at the edge to pass another vehicle is prohibited. That solid edge line marks the boundary of the roadway and the shoulder, indicating driving space ends there. Driving or passing onto the shoulder is unsafe and often illegal because shoulders can be rough, inclined, or have obstacles and pedestrians. To pass, you must stay in lanes where passing is permitted (usually with dashed lines) and only when it’s safe.
