You arrive at an uncontrolled four-way intersection at the same moment as a driver on your right. Neither street has a stop sign. Who must yield?

Why B is correct

At an uncontrolled intersection where two vehicles arrive at essentially the same time, the driver on the left yields to the driver on the right. The reason is physical rather than arbitrary: the vehicle approaching from your right sits closer to the point where your two paths cross, so letting it go first removes the conflict immediately. If both drivers simply insisted on their own vague claim of arriving first, the result would be a collision in the middle of the box, which is why the law supplies a fixed tiebreaker instead. Yielding here means slowing or stopping until that driver has cleared the intersection, not maintaining your speed and hoping the gap holds.

Why the other options are wrong

A. The driver on your right must yield, because the left side always has priority

There is no rule giving the left-hand driver priority at an open intersection. The tiebreaker in the handbook runs the other way: the vehicle on the right is nearer to the conflict point, so the driver on the left is the one who has to give way.

C. Whichever driver is operating the larger vehicle

Vehicle size, weight, or price never decides who proceeds first at an intersection. Right of way is assigned by rules that any driver can apply in advance, which is exactly why a pickup truck and a compact car follow the same order here.

D. Whichever driver signals a turn first

A turn signal tells other road users what you intend to do, but it never creates priority. A driver who signals first still has to yield to traffic that already holds the right of way, including the vehicle on the right at an open intersection.

On the road

Picture a neighbourhood grid on a Saturday morning: no stop signs, hedges cutting off the corner view, two cars rolling up at the same moment. The driver on the left eases off the accelerator, lets the car on the right go, then follows. On the written test the same situation is usually drawn as an overhead diagram, and you have to pick which car moves first.
