Which interval is used as the warning phase before red on signals?

• A. All-red interval.
• B. Green interval.
• C. Amber interval.
• D. Walk interval.

Answer: (C)

The amber interval is the warning phase before red on signals. It signals that the light is about to change, giving drivers a final cue to slow down and prepare to stop. If you’re close enough that stopping safely isn’t possible, you may proceed with caution, but otherwise you should brake and stop. This interval helps create a safe transition for both vehicle traffic and pedestrians. The green interval is when you may go, the walk interval is for pedestrians crossing, and the all-red interval is a safety clearance where all directions are stopped before the next cycle begins.
