A 29-seat microbus is used for a private company's employee shuttle with no fare charged to the public. What must the driver still verify?

1. Vehicle size, licence category, insurance and company rules, and whether the transport purpose requires any additional entitlement.
2. Nothing, because 29 seats always means any driver may operate it.
3. Only that the trip is shorter than one hour.
4. Only that the bus is painted white.
