To make a right turn at an intersection where the traffic signal displays a flashing red arrow, you should treat it as a stop sign.
Come to a complete stop and yield the right-of-way to any other vehicles or pedestrians in the intersection. Once it is safe to do so, proceed with the right turn. Remember to always follow the rules of the road and exercise caution when making turns.
