Who must yield when two vehicles enter an intersection from different highways?

Answer: B — The vehicle on the right

When two vehicles enter an intersection from different highways, the vehicle on the right has the right of way. This is because a vehicle turning right from one highway should not impede the path of a vehicle driving straight on the other highway. Option A is incorrect because it refers to the position of the vehicles, not their direction of travel. Option C is incorrect because speed does not determine right of way in this scenario. Option D is incorrect because size does not determine right of way in an intersection.
