Under what condition can you cross double yellow lines to pass another vehicle?

The correct condition for crossing double yellow lines to pass another vehicle is when the vehicle in front of you has moved to the right to let you pass. This scenario indicates that it is safe to overtake because the driver in front has signaled their intention to allow you to proceed. It suggests a collaborative effort between drivers to ensure safety while passing.

In general, double yellow lines indicate that passing is not permitted. The presence of those lines is specifically meant to warn drivers of the risks involved in passing on that roadway. However, if the vehicle in front of you actively creates an opportunity by moving aside, it opens a space for you to safely maneuver past, aligning with the shared responsibility of road safety.

The other conditions outlined do not justify crossing the double yellow lines. For instance, simply having a clear road or no oncoming cars does not guarantee safety or legality in passing. Similarly, driving below the speed limit does not automatically allow a driver to pass, especially when double yellow lines are present, as the focus is primarily on maintaining safety and complying with traffic regulations.
