Final answer:
When two vehicles reach an uncontrolled intersection at approximately the same time, the right-of-way is given to the vehicle approaching from the right. This means that the correct answer is D. The vehicle approaching from the right. The vehicle approaching from the left should yield to the vehicle on the right.
Step-by-step explanation:
When two vehicles reach an uncontrolled intersection at approximately the same time, the right-of-way must be provided to the vehicle approaching from the right. This rule is a common driving principle used to prevent collisions at intersections where no signs or signals dictate the priority. It does not rely on the speed at which the vehicles are traveling; hence, neither the vehicle moving the fastest nor the slowest automatically has the right-of-way. Given this information, the correct answer to the question is D.The vehicle approaching from the right.
