Final answer:
The white line parallel to your lane on the right is the edge line, indicating the edge of the vehicular portion of the roadway and should not be crossed.
Step-by-step explanation:
The white line parallel to your lane on the right is called the edge line. It indicates the edge of the vehicular portion of the roadway and should not be crossed. The purpose of the edge line is to provide a visual boundary and separate traffic flow in opposite directions. It helps in maintaining order and safety on the road.
This white line is not related to parking or passing on the right. A solid white line usually prohibits passing, while a broken white line allows passing if it is safe and legal to do so, but these rules do not apply to the edge line.
Therefore, the correct answer is: The edge of the vehicular portion of roadway and may not be crossed.
