A bus stop is next to a cycle lane, and a motor vehicle approaches in the lane beside that cycle lane on a 50 km/h road. The bus signals to leave the stop. What does Finnish law require?

1. The approaching motor vehicle must yield to the bus leaving the stop
2. Only cyclists must yield; the adjacent motor lane never yields
3. The bus must wait until every lane in the city is empty
4. The rule applies only if the bus is empty
