A SHANGHAI taxi driver who charged an American passenger three times the correct fare is among 400 cabbies who have had their licenses revoked or suspended this year, officials said yesterday.

As well as overcharging, other common offences included taking longer routes, swapping transport cards for ones without credit and lending cabs to other drivers, the Shanghai Traffic Law Enforcement Team said.

A total of 93 cabbies had their licenses revoked for at least five years for serious breaches of regulations, said the enforcement team.
