A steady green traffic light at an intersection means:
- Increase your speed.
- Adjust your mirrors.
- You may continue through the intersection at a safe and reasonable speed, if it is clear to do so. ✓
Answer: C. You may continue through the intersection at a safe and reasonable speed, if it is clear to do so.
A steady green light means you may continue through the intersection at a safe and reasonable speed, provided the intersection is clear.
Why this is the answer
The handbook's traffic-signal section explains what the lights indicate and points you to right-of-way rules for green. Those rules say a green light does not settle every conflict. You must yield to traffic already in the intersection, wait for pedestrians in a crosswalk, and stay out of the intersection when traffic is backed up. That is why the safe choice is to go through only when it is clear, not to treat green as an automatic command to move fast.
Why the other answers are wrong
- A. Increase your speed. — Increasing your speed is not what a green light authorizes; the handbook says you must yield to traffic already in the intersection and wait for pedestrians, so speeding up can conflict with those duties.
- B. Adjust your mirrors. — Adjusting your mirrors is a separate driving task and is not what a steady green light means; the handbook's green-light discussion is about yielding and proceeding through the intersection when clear.
Remember it
Green means go only when the way is clear — keep your eyes on the intersection, not on your mirrors.
