Q7. If a passenger refuses to pay enough fares or any at all, what can a bus driver do?
Bus drivers may refuse entry to his vehicle or may order any person to remove himself from the vehicle where he has reasonable grounds to believe that such person has committed or is about to commit an offence against the Road Traffic (Public Service Vehicles) Regulations (Cap. 374D): see Regulation 56(1) of the Road Traffic (Public Service Vehicles) Regulations (Cap. 374D).
No person shall board a public bus, knowing or having reason to believe that he cannot pay the fare and with intent to avoid payment of the fare; or dishonestly avoid payment of a fare due from him: see Regulation 48(2)(a) and (b) of the Road Traffic (Public Service Vehicles) Regulations (Cap. 374D).
Thus, bus drivers may refuse entry to the bus or may order the passenger to remove himself from the bus.
Strictly speaking, bus drivers may arrest the passenger and may detain such person until he can be handed over to a police officer: see Regulations 58(a) and 58(b) of the Road Traffic (Public Service Vehicles) Regulations (Cap. 374D).
