When approaching an unmarked intersection, which vehicle has the right-of-way?

Answer: C — The vehicle coming from the right

In the context of an unmarked intersection, the vehicle coming from the right typically has the right-of-way. This rule is commonly adopted as a general guideline to ensure safe and orderly traffic flow when no specific traffic control devices, such as signs or signals, dictate otherwise. This approach is rooted in the principle that if two vehicles arrive at an intersection simultaneously and there are no signals or signs to indicate priorities, yielding to the driver on the right helps prevent confusion and potential collisions. This decision-making process is crucial because it establishes a standard behavior that drivers can expect from one another, thereby enhancing safety for all road users. While other options may have their own contexts, such as priority rules at marked intersections or other specific traffic laws, the most widely accepted practice at unmarked intersections is to yield to the vehicle on the right.
