Argentina has the highest traffic mortality rate in South America per 100,000 inhabitants, with Argentinian drivers causing 20 deaths each day (about 7,000 a year), with more than 120,000 injured people each year. These deaths have included some unfortunate tourists. Pedestrians should exercise extreme caution. Do not jaywalk if you do not feel comfortable, and always keep your eyes about you when crossing the street.

There is plenty of activity and foot traffic throughout the night. Nice areas have a very thorough police presence, perhaps one officer per 3 blocks, plus store security and auxiliary patrols. Public security in all major cities like Buenos Aires, Córdoba and Rosario is handled by the Federal Police and the National Gendarmerie or the Naval Prefecture, especially in the Puerto Madero area of Buenos Aires.

As in any large city, certain particular neighborhoods in Buenos Aires and other cities are very dangerous. Some shady neighbourhoods include Retiro, Villa Lugano, La Boca and Villa Riachuelo. Ask trusted locals, such as hotel desk staff or police officers, for advice. Pay attention to your environment and trust your instincts. If an area seems questionable, leave.

Many people in the street and in the subway hand out small cards with horoscopes, lottery numbers, pictures of saints, or cute drawings on them. If you take the card, the person will ask for payment. You can simply return the card along with a no, gracias. or simply in silence if your Spanish is not good. Persistent panhandlers are usually not dangerous; a polite but firm no tengo nada ("I don't have anything") and/or hand gestures are usually enough.

Most robberies are not violent, if it is just give the robbers everything, because they may be on drugs, drunk, have a knife or a gun; in most cases, if your wallet is stolen, you won't even notice until hours later. In the unlikely event that you are confronted by a mugger, simply hand over your valuables - they are replaceable. Watch out for pickpockets in the subway and on crowded city streets. Never hang your purse or bag from the back of your chair in a cafe or restaurant - stealthy theft from such bags is common. Keep your purse or backpack on the floor between your legs while you eat.

Popular demonstrations are very common in Buenos Aires, and are best avoided by tourists as these demonstrations sometimes grow into violent confrontations with the police or National Gendarmerie, particularly as they approach the government buildings in the city center.

There are rogue taxis operating in Buenos Aires whose drivers kidnap and rob tourists and locals alike. If you take a taxi, it's best to have your hotel or business phone for a radio taxi. If you must hail one on the street, look for one with the lighted gear on the roof and the designation "Radio Taxi" next to a phone number. Try to have small bills ready, as you may receive counterfeits if you pay in large denominations.

It is recommended that you carry some ID with you, but not your original passport. A copy of it (easily provided by your own hotel) should be enough.
