What does it mean if a pedestrian signal flashes "don't walk"?

When a pedestrian signal flashes "don't walk," it is an indication that pedestrians should not enter the crosswalk. This flashing signal typically serves as a warning that the light for vehicles is about to change and that conditions may soon be unsafe for pedestrians. It helps to ensure the safety of individuals by preventing them from starting to cross when there may be insufficient time to complete the crossing before traffic resumes.

The context of this signal is essential for pedestrian safety. By adhering to this warning, pedestrians can avoid putting themselves at risk of being in an intersection when vehicles may be moving through. It is crucial for pedestrians to wait until the signal changes to a solid "walk" indication, which designates that it is safe to cross.
