Is a bus driver permitted to refuse entry of children trolleys into the bus?

1. Correct answer: Yes, in the event that the bus is crowded and there is not enough space.
2. Yes, when there is no more space in the luggage compartment of the bus.
3. The driver is always obliged to let children trolleys on the bus.
4. Yes, but only when the trolley is designed to carry one baby (not when it is a trolley for twins).

WhyYes, the driver may refuse a stroller if the bus is crowded and there is no room for it. Whether it is a double or a single one does not matter.
