Sample question from test 2
signals-markings
What does a steady yellow traffic light warn an Illinois driver?
- The driver may enter without checking the intersection
- The signal will remain green for another full cycle
- Cross traffic must stop immediately
- The signal is changing from green to red
Answer: The signal is changing from green to red. A steady yellow light warns that the signal is changing from green to red. It is not a promise of another green cycle and does not mean the driver may enter without checking the intersection. Cross traffic does not automatically receive a separate command from the yellow indication. The manual adds that when the red light appears, a driver must not enter the intersection. Treat yellow as a transition warning, check position and traffic, and avoid starting an entry that cannot be completed safely.
