Traffic signals sometimes display arrows to control turns from specific lanes. A green arrow:
- Is used only on one-way streets.
- Has the same meaning as a circular green traffic light, but traffic must turn in the direction indicated by the arrow. ✓
- Means that you may proceed, but only if the green arrow is accompanied by a circular green light.
- Points the way to an airport.
Answer: B. Has the same meaning as a circular green traffic light, but traffic must turn in the direction indicated by the arrow.
A green arrow has the same general meaning as a circular green light, except you must go in the direction the arrow points.
Why this is the answer
The handbook describes a steady green light as permission to go while yielding to other traffic as the law requires. It describes a green arrow as permission to go in the direction of the arrow, again with the same duty to yield. So the arrow works like a green light for that particular direction, and it tells you which way your turn or movement is allowed.
Why the other answers are wrong
- A. Is used only on one-way streets. — Nothing in the handbook says green arrows are used only on one-way streets; they are described as a traffic signal that can control movement in the arrow's direction.
- C. Means that you may proceed, but only if the green arrow is accompanied by a circular green light. — A green arrow does not depend on a circular green light being present, and the handbook even describes a green arrow shown with a red light as allowing movement toward the arrow when the intersection is clear.
- D. Points the way to an airport. — A green arrow is a traffic control signal for turning or moving in the shown direction, not a sign pointing to an airport.
Remember it
Think of a green arrow as a green light limited to one direction: go that way, but still give way as required.
