As a general rule, older drivers tend to be more amenable to the meters, while the younger ones tend to gun for big fares from tourists. Also avoid the parked taxis (dishonest drivers prefer to wait for gullible tourists) and hail a moving taxi (a red light on the dashboard indicates if they are available). The majority of taxis are new (less than two years old), and it’s best to avoid the older taxis as their air-conditioners function poorly, and these drivers tend to be less reliable. The great majority of taxi drivers are reasonably honest, though, so always opt for a taxi instead of a tuk-tuk.
