Final answer:
There are three ways to know when a green light is going to change: observing the pedestrian signal, observing other traffic signals, and noticing patterns.
Step-by-step explanation:
There are a few ways you can know when a green light is going to change:
- Observing the pedestrian signal: When the pedestrian signal starts flashing or counting down, it usually indicates that the green light is about to change to yellow.
- Observing other traffic signals: If you see other traffic signals turning yellow or red, it's a good indication that the green light is about to change.
- Noticing patterns: In some areas, traffic signal patterns are consistent, so after some time, you may notice a pattern that can help you anticipate when the green light will change.
