When two vehicles arrive at a four-way stop at the same time, who has the right-of-way?

Question: When two vehicles arrive at a four-way stop at the same time, who has the right-of-way?

Answer options:

• The vehicle on the left ✅ The vehicle on the right
• The larger vehicle
• Whoever signals first

Correct answer: The vehicle on the right

Explanation: Under Québec’s Highway Safety Code, when two vehicles arrive at an all-way stop intersection at the exact same time, the rule of priority dictates that the vehicle on the right has the right-of-way. The vehicle on the left must yield, making that option incorrect, while physical size and signaling order have no legal bearing on right-of-way determination. This basic priority rule ensures orderly traffic flow and prevents collisions at intersections. On the SAAQ knowledge test, questions regarding right-of-way at stop signs and intersections are highly common, making it crucial to memorize who must yield in various simultaneous arrival scenarios.
