Which interval is the warning phase before red in traffic signals?

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

Answer: (C)

Amber interval is the warning phase before red. It appears after the green light and before red, giving drivers a brief cue to slow down and stop if it’s safe to do so. This transition helps reduce abrupt stops and enhances safety by signaling the impending change. It’s not the green interval, which means go; it’s not the walk interval, which is for pedestrians; and it’s not the all-red interval, which is a different phase where everyone must stop to clear the intersection.
