Answer
Yes, regular city taxis operate on a taximeter. The fare is based on the current tariff, distance and time, so traffic or waiting increases the cost. The driver must turn on the meter at the beginning of the trip; clarify any fixed price without a clear basis before getting in.
In the city centre, you can take a taxi from an official rank, hail a vacant taxi or book one through an available service. For a trip at night, with luggage or to the terminal, booking is more convenient, as it keeps a record of the vehicle details. Check the possible surcharges for time and luggage in the current fare.
If the meter is not on or there is a dispute, take a photo of the car’s registration number and ask for a receipt. If you need to know the cost in advance, compare an app’s estimate with public transport, but bear in mind that traffic conditions can change the actual taxi fare.
