A new taxi industry regulation will allow passengers to refuse to pay fares if drivers break certain rules.
Â
According to the regulation, which comes into effect on Jan 1, if drivers don't use meters properly, don't get passengers to destinations on time, don't give receipts or don't accept payment by subway cards, passengers can refuse to pay the fare.
Â
The regulation also requires drivers to choose the most direct route, and says they cannot refuse passengers' requests, negotiate the price or drop off passengers in the middle of the trip.
Â
Drivers who don't obey the rule may be punished with fines ranging from 50 yuan to 200 yuan ($8 to $32).
Â
In addition, the regulation creates more detailed standards, including rules that drivers cannot smoke or eat food with strong smells.
Â
The regulation encourages cities to develop a taxi appointment service through phone, mobile app or website.
