What action should be taken on encountering a yellow arrow signal?

When you encounter a yellow arrow signal, it indicates that the signal is about to change to red. This is a warning for drivers that the road may soon be closed for turning in that direction. The correct action in this situation is to continue with your turn if you are already in the intersection. This means you should complete your maneuver safely and without hesitation, provided it is safe to do so.

This guidance is shaped by the need for safety and traffic flow; stopping suddenly in the intersection can lead to accidents, especially if vehicles are behind you intending to make the same turn. Therefore, as long as you have entered the intersection when the yellow arrow appears, it is appropriate to execute your turn. It promotes safe driving behavior by helping maintain the movement of traffic while also ensuring that you are not placed in a hazardous situation by stopping unexpectedly.
