Warning, Construction & Information SignsStandalone practice
A yellow diamond sign shows a traffic signal with red, yellow and green lights. What should you expect ahead?
Correct answer: A traffic signal ahead, so slow down and be ready to stop for it
Why
Yellow diamonds warn of hazards that are hard to see in time, and this one is used where a curve, hill or high speed could hide a signal. At high speed, a light that turns yellow can leave too little room to stop. New Jersey law also calls for a lower speed as you approach any intersection.
