What is correct in this situation?

In this situation, you are driving near a truck while approaching an advisory bike lane. According to German traffic regulations, it is generally allowed to use an advisory bike lane if you have checked that it is safe to do so.

1. **Allowed to drive on the advisory bike lane after ruling out risks**: This means you can move into the bike lane if you ensure there are no cyclists present and that it's safe to do so. Observing the traffic situation is crucial to prevent accidents.

2. **Allowed to drive on the advisory bike lane only until past the truck**: This indicates that you can use the bike lane temporarily while passing the truck, provided that it's safe and free of cyclists.

The combination of these two points is correct because it acknowledges both the need for caution and the allowance to use the lane for safety when navigating around larger vehicles. The third statement—that it is not allowed to drive on the bike lane—is incorrect in this context, as there are situations where it is permissible, as long as safety is prioritized.
