For info, there are still non aircon and partial aircon SBST
services here. So there's still the need of declaring the aircon
status of a SBST service. For SMRT Bus, I don't see the need as all
its buses are aircon.
Yes, the bus company would violate the regulation in this case. Two
days ago (14 June), 3603 which is a non aircon Scania was deployed
on Townlink 291, which is declared as a full aircon service.
