If the robot is red and the green arrow flashes to the right as indicated in X5, what does this mean?

When the robot is red and the green arrow is flashing to the right, it indicates that you are permitted to turn right. This signal is designed to guide drivers where they are allowed to proceed, particularly at intersections or when dealing with complex traffic situations.

A flashing green arrow often signifies that the specific turn can be made safely, even when the main signal is red. It allows for a right turn, giving drivers an indication that they may proceed cautiously in that direction while ensuring that it's clear of any oncoming traffic or obstacles.

The other choices do not apply in this instance. For example, stopping and waiting would not be appropriate when the arrow indicates a permitted action, and proceeding straight or turning left does not align with the instruction given by the flashing green arrow to the right. Thus, in this context, the flashing green arrow conveys permission to turn right.
