When two vehicles approach an unmarked intersection at the same time, which vehicle must yield?

Answer: B — The vehicle on the left

When two vehicles approach an unmarked intersection simultaneously, the driver of the vehicle on the left must yield to the driver on the right. This rule is grounded in the principle of right-of-way, which is designed to prevent confusion and collisions at intersections, especially in the absence of traffic signals or signs. The vehicle on the right has the priority because it is generally considered to be the more advantageous position in terms of safety and traffic flow. By yielding to the vehicle on the right, the driver on the left contributes to a smoother and safer navigation of the intersection. Understanding this right-of-way rule is essential for safe driving habits and compliance with traffic laws in Idaho and many other states.
