Who is expected to approach from your opposite direction when the color of the arrow in the sign is yellow?

Why this is the answer
The correct answer in the official bank: Public transportation vehicle or any other vehicle that is permitted according to the sign.
A yellow arrow on this sign marks a lane where public transport travels against the general direction of traffic. So vehicles coming toward you in it are public transportation vehicles, or other vehicles that a sign specifically permits to use that lane. It has nothing to do with trains, and it is not a lane for vehicles carrying several passengers, which has its own sign.
