What should you do at a four-way stop when two vehicles arrive at the same time?

Answer: A — The vehicle on the left must yield to the vehicle on the right

At a four-way stop, when two vehicles arrive at the same time, the rule that applies is that the vehicle on the left must yield to the vehicle on the right. This means that the driver on the left should allow the driver on the right to proceed first. This rule is designed to promote safety and order at intersections, helping to avoid confusion about who has the right of way. Understanding this rule is crucial for safe driving, as it encourages drivers to be aware of their surroundings and the position of other vehicles. Yielding in this context prevents potential accidents that may occur if both drivers assume they can go at the same time. This system of yielding ensures clear communication between drivers and supports smoother traffic flow at intersections.
