Is it permitted to smoke in a bus?

1. Yes – within the limits of urban roads only.
2. Yes – but only in the back of the bus.
3. Correct answer: No – and it is even obligatory to place a “no smoking” sign inside the bus.
4. Yes – but only when the air-conditioning system doesn’t work.

WhySmoking on a bus is never allowed. Besides the ban, the operator must put up no smoking signs inside. Air conditioning, the city or the back row change nothing.
