What does a red flashing light indicate at an intersection?

A red flashing light at an intersection serves as a critical signal that demands immediate attention and action from drivers. It indicates that vehicles must come to a complete stop, similar to a stop sign. After stopping, drivers are required to proceed only when it is safe to do so, ensuring that they check for oncoming traffic and pedestrians before continuing.

This rule is in place to promote safety at intersections, where visibility and right-of-way can be complicated. The process emphasizes caution and the need for drivers to be significantly aware of their surroundings before moving forward.

The other options suggest different actions that do not align with the established meaning of a red flashing light. For example, proceeding with caution implies a level of ongoing movement rather than a complete stop, while turning right only may not be appropriate unless a certain traffic condition permits it. Yielding to traffic, while necessary in some situations, also does not replace the requirement to stop first when a red flashing light is present.
