What does a red-red flashing mode provide to traffic at an intersection?

A red-red flashing mode at an intersection indicates that all traffic movements must yield or stop, operating under the same principles as an all-way stop. This mode is typically utilized in situations where standard traffic signals may not be operational or are being replaced, ensuring safety while managing intersection control. During this phase, vehicles coming from all directions are required to come to a complete stop and then proceed only when it is safe, similar to what would occur at an all-way stop. This mode effectively helps to reduce confusion and potential accidents by establishing clear procedures for drivers, ensuring that all traffic flows in a controlled manner.

In contrast to other options, such as granting right-of-way to a minor street or allowing continuous movement, a red-red flashing mode maintains strict control and emphasizes safety by compelling all vehicles to stop prior to proceeding with caution. Yielding to pedestrians, while important, does not specifically describe the traffic control implications of a red-red flashing signal.
