How would you (vehicle no. 3) conduct yourself in the following intersection?

- Give right of way to the motorcycle only (2).
- Correct answer: Give right of way to the motorcyclist (2) and to the yellow bus (1).
- Give right of way to the yellow bus only (1).
- Drive forward carefully. The other drivers (of vehicles 1 and 2) must yield.
Why this is the answer
The correct answer in the official bank: Give right of way to the motorcyclist (2) and to the yellow bus (1).
The "Give right of way" sign requires you to give right-of-way to vehicles that are in the intersection or crossing your path. The motorcycle comes from the crossing road. The yellow bus comes from the opposite direction and turns onto the road on the right, so it crosses your lane. So give right-of-way to both, and continue only when it is safe.
