When two vehicles reach an uncontrolled intersection at the same time, which vehicle has the right-of-way?

Answer: C — The vehicle to the right

When two vehicles reach an uncontrolled intersection at the same time, the vehicle to the right has the right-of-way. This is because in many countries, including the USA and Canada, cars drive on the right side of the road. Therefore, the vehicle to the right has a clear view of the intersection and can proceed safely. Option A and B are incorrect because the size or loudness of a vehicle does not determine the right-of-way. Option D is incorrect because vehicles on the left would have to cross the path of vehicles on the right, potentially causing an accident. Therefore, in this scenario, the vehicle to the right has the right-of-way.
