Question: If a traffic signal is completely out, treat the intersection as:

Answer options:

  • A one-way street ✅ A four-way stop
  • An open road
  • A roundabout

Correct answer: A four-way stop

Explanation: Under the Quebec Highway Safety Code, when a traffic light is completely inactive due to a power failure or malfunction, drivers must treat the intersection as a four-way stop. This rule ensures orderly traffic flow by requiring all vehicles to come to a complete stop and yield to the first vehicle that arrived, or to the vehicle on their right. Treating the intersection as an open road, a one-way street, or a roundabout is incorrect and highly dangerous, as these options ignore the statutory requirement to stop and negotiate right-of-way safely. On the SAAQ knowledge test, remembering emergency yielding rules for malfunctioning signals is crucial for demonstrating safe defensive driving practices.
