Under what condition is it permissible to cross a double center line to pass another vehicle?

The correct answer is based on the traffic regulations regarding road markings. A broken yellow line on your side of a double center line indicates that passing is allowed for vehicles traveling in that direction. This marking signifies that the roadway is open for safe overtaking when it is safe to do so.

A solid yellow line, in contrast, indicates that passing is prohibited in that lane. Therefore, if a solid yellow line is present on your side, crossing the double center line to pass another vehicle would be illegal and unsafe.

The option that states "any double center line" is too general and does not account for the specifics of the markings, which dictate whether passing is allowed. Lastly, indicating that passing is permitted only during daylight hours does not align with the driving regulations, as the legality of passing depends primarily on the road markings rather than the time of day.

Thus, passing is permissible when there is a broken yellow line on your side of the road, indicating that you can safely overtake another vehicle when conditions allow.
