Introduction
Traffic signals use lights to direct the safe movement of vehicles and pedestrians. While most people are familiar with the basic red, yellow, and green lights, the green arrow provides a very specific instruction that every driver must understand.
What Does a Green Arrow Mean?
-
A green arrow allows you to make the movement shown by the arrow — usually a left turn or right turn — with the right-of-way.
-
When the green arrow is on, oncoming traffic is stopped by a red light, so your turn is protected.
How to Respond to a Green Arrow
-
Make sure you are in the correct lane for the direction of the arrow.
-
Proceed carefully in the direction of the arrow.
-
Yield to pedestrians and bicyclists in the crosswalk.
-
Complete the turn smoothly — the signal guarantees you a safe gap, but it doesn’t remove your responsibility to look.
Protected vs. Permissive Turns
-
Protected Turn (Green Arrow): You may turn safely in the arrow’s direction. Other traffic must wait.
-
Permissive Turn (Green Circle): A plain green light may allow you to turn left, but you must yield to oncoming cars and pedestrians first.
Key Safety Reminders
-
Never try to “beat the arrow.” If it turns yellow or red, stop unless you are already in the intersection.
-
Always check for pedestrians and cyclists, even if you have the arrow.
-
Be alert for turning lanes and pavement arrows that show which movements are legal.
Conclusion
The green arrow is one of the clearest signals you will see: it gives you a protected movement in the direction shown. By obeying it, yielding to pedestrians, and making smooth, careful turns, you’ll handle intersections safely and confidently.
