Taxis in Rome are easily identifiable; they are white, have a sign on the roof and a taxi identification number on the side of the door. To catch one look for a yellow taxi stand, they’re dotted across the city.
Taxis can be fairly expensive and like in many cities drivers have been known to overcharge tourists. Always take a licensed taxi that uses a meter. And be careful when paying to hand over small notes one by one, counting them out. Drivers have been known to say you handed them a smaller note than you did in reality, making you pay more.
Can’t spot a yellow stand? You can call for a taxi by phone. Be warned though that the meter will start from the time the taxi is dispatched, so don’t be alarmed if you see a charge already showing on the meter.
