What is the rule concerning right of way at intersections?

The rule concerning right of way at intersections dictates that the vehicle on the left must yield to the vehicle on the right. This principle is established to help manage traffic flow and reduce the likelihood of collisions at intersections, particularly when vehicles approach from different directions.

When two vehicles arrive at an intersection simultaneously, this rule clarifies which vehicle has priority. By yielding to the vehicle on the right, drivers can navigate intersections more safely and efficiently. This rule is particularly important in situations where traffic control devices, like stop signs or traffic signals, are not present, allowing for smoother and more predictable interactions between drivers.

The other choices create confusion or imply improper traffic behaviors that do not align with safe driving practices. For instance, stating that the last vehicle to arrive has the right of way contradicts the fundamental principle of yielding to the vehicle on the right. Additionally, the idea that vehicles must proceed regardless of arrival time could lead to chaos at intersections, increasing the risk of accidents. Lastly, requiring all vehicles to stop until traffic clears is impractical and could cause unnecessary delays, undermining efficient traffic movement.
