- Steady green: proceed after yielding to traffic and pedestrians already in the intersection.
- Steady yellow (amber): red is coming; stop if you can do so safely.
- Steady red: come to a complete stop.
- Flashing red: stop completely, then proceed when safe (like a stop sign).
- Flashing yellow: proceed with caution.
- Flashing green / green arrow: an advanced (protected) turn; oncoming traffic is held.
- Power failure: if the lights are dark, treat the intersection as an all-way stop.
Recall: What does a flashing red light require? How do you treat an intersection whose lights have failed?
