If two vehicles arrive to a four-way stop at the same time:

1. The vehicle on the left must yield to the vehicle on the right. ✓
2. The vehicle on the right must yield to the vehicle on the left.
3. Drivers must make hand motions to communicate with each other.
4. One driver should proceed without stopping.

Answer: A. The vehicle on the left must yield to the vehicle on the right.

At a four-way stop where two vehicles arrive at the same moment, the driver on the left yields, so the vehicle on the right goes first.

Why this is the answer

The handbook passage about the four-way stop sign says that all traffic must stop before proceeding in the order it arrived, and that when two vehicles get there at the same time, you yield to the vehicle on your right. That rule puts the duty on the driver on the left side of the pair, which is exactly what the bank answer says. Nothing in the passage asks drivers to signal each other by hand or lets anyone skip the stop.

Why the other answers are wrong

• B. The vehicle on the right must yield to the vehicle on the left. — This flips the rule around; the handbook says you yield to the vehicle on your right, not the other way.
• C. Drivers must make hand motions to communicate with each other. — The handbook gives a fixed order-of-arrival rule for these intersections and never asks drivers to work it out with hand motions.
• D. One driver should proceed without stopping. — The passage says all approaching traffic must stop before proceeding, so no driver gets to roll through.

Remember it

Think of it as a courtesy to your right hand: whoever is sitting to your right at the stop gets to go first.
