You and another driver reach a four way stop at the same moment. The other car is directly to your right and both of you are going straight ahead.
- You go first, because a driver going straight has priority over one on a side street
- The driver on your right goes first
- You go first, because the vehicle on the busier street goes first
- Neither of you has priority, so creep forward until one of you gives way
The answer is B
At a four way stop the order is set by who stopped first. When two drivers stop at the same instant the tie is broken in favour of the vehicle on the right, so the driver beside you goes first. A fixed rule matters here because two drivers guessing at each other is exactly how these collisions happen.
