In Rome, you can hail a cab by standing at the side of the road and raising your arm to signal the driver to come. Look for cabs that have a sign on the roof that says "TAXI" indicating that they are for hire. Be aware that some cab drivers in Rome try to overcharge. Therefore, it is best to agree on a price before getting into the cab or insist on using the taximeter. Also, it is advisable to have cash with you, as not all cabs in Rome accept credit cards.
