Why do we need red arrows?

Question

Why do we need red arrows? Is there really a need for them?

Answer 1

The red arrow indicates that left turns are prohibited in that intersection when the red arrow is illuminated. Left turns are permitted in that intersection only when the green arrow is illuminated. Red arrows are put in operation where the usual left turns yield on green are hazardous due to heavy opposing traffic or the left turn would have the driver cross multiple lanes of opposing traffic. The green arrow gives drivers a "protected" left turn while opposing traffic is stopped by the red signal. Drivers making a left turn should only enter the intersection when the green arrow is illuminated. The yellow arrow illuminates to warn the drivers making a left turn that the red arrow is about to illuminate, the red arrow prohibiting left turns and indicating that opposing traffic is about to start moving.

Answer 2

I used to drive over the road and never saw a real need for red arrows. A solid red light should be just as good. We don't have them red arrows in Missouri to my knowledge but we do have green ones and yellow (or amber) ones. The real important thing in my opinion is that all the states have a uniform system of visual traffic controls that everyone understands.

A red arrow means no turn on red, a fact lost on most motorists.
