Is a bus without passengers permitted to enter a road on which the following road sign is placed?

- Yes, because all vehicles are permitted to drive on that road.
- Correct answer: Yes, according to the provisions of the sign.
- No, because it doesn’t carry the number of passengers required by the sign.
- No, because a bus without passengers does not serve as a bus.
Why this is the answer
The correct answer in the official bank: Yes, according to the provisions of the sign.
The sign allows trams, buses, taxis and cars carrying at least four occupants to use the road. The passenger requirement applies only to the car shown next to 4+, not to the bus, so a bus may enter even when it carries no passengers. The road is not open to all vehicles, only to those shown on the sign.
