What does a red flashing signal mean?

A red flashing signal signifies that drivers must stop completely at the intersection or location where the signal is present. This is similar to the function of a stop sign, which also requires a full stop before proceeding. The purpose of the red flashing signal is to alert drivers to a potentially dangerous situation, such as when visibility is limited or when crossing traffic needs to be prioritized for safety. When faced with a flashing red signal, drivers must check for oncoming traffic or pedestrians and only proceed once it is safe to do so.

The context of the question reflects crucial safety protocols essential for all drivers to understand, especially in Hawaii, where unique traffic conditions can arise.
