What is this experiment about?
You're in charge of the intersection! Tap the lights to change them and keep both cars and people moving safely. Red means stop, yellow means get ready, and green means go.
Questions kids ask
- What does a yellow traffic light mean?
- Yellow means the light is about to change — drivers should slow down and prepare to stop.
- When is it safe to cross the street?
- It's safest to cross when the pedestrian signal shows a walking person and traffic has stopped, after looking both ways.
- Why do traffic lights matter?
- They let cars and people take turns moving through a shared space safely, without crashing into each other.
