Warning, Construction & Information SignsStandalone practice
A yellow diamond contains a vertical red, yellow and green traffic-signal symbol. What does it tell an approaching driver?

Correct answer: A signal is ahead; be ready to obey its actual light.
Why
Expect a traffic signal ahead. Approach at a speed that allows you to see and respond to the real signal, traffic and any queue. The red/yellow/green symbol on the warning sign does not tell you which light is currently operating.
