You may pass another vehicle on a 2-lane roadway only if:

Passing another vehicle on a 2-lane roadway is permitted when there is a single broken center line. This indicates that the roadway is designated for two-way traffic, and the broken line signifies that drivers can legally pass other vehicles if it is safe to do so. The presence of a broken center line means that there are no restrictions placed on passing, allowing drivers to maneuver around slower vehicles when conditions are suitable—such as good visibility, no oncoming traffic, and sufficient space to complete the pass safely.

In contrast, a solid center line indicates that passing is not allowed, as it represents a no-passing area due to potential hazards such as curves or intersections. A no-passing zone is specifically marked to warn drivers that passing maneuvers could lead to dangerous situations, thus making it illegal to overtake vehicles in that section. A traffic light being green pertains to intersections and does not apply to the basic rules of passing on a roadway. Therefore, the only situation that permits passing on a 2-lane roadway, as described, is when a single broken center line is present.
