Road Signs

You are approaching an intersection at 50 km/h when the light turns yellow. You are about 20 metres from the stop line. What should you do?

Ontario road sign — Judge whether you can stop safely — if yes, brake smoothly and stop; if no, continue with caution
Show Answer & Explanation
Correct Answer: B. Judge whether you can stop safely — if yes, brake smoothly and stop; if no, continue with caution

Yellow is a judgment decision based on distance, speed, and following traffic. A smooth safe stop is best when possible; if too close, maintain speed and continue carefully. Never accelerate on yellow — that is how right-angle collisions happen.

Why the other answers are wrong

  • A.Slam the brakes hard to stop before the stop lineSlamming the brakes can cause rear-end collisions; smooth controlled braking is the correct technique.
  • C.Speed up to clear the intersectionSpeeding up on yellow is how intersection collisions occur when opposing traffic gets a green.
  • D.Honk and proceed throughHonking does not grant passage; yellow decisions are about distance and safe stopping.
