At the airport, watch for your suitcase as it appears on the carousel. Don't hang back and wait for the crowds to disperse - you might find that someone else has already taken your bag in the meantime.
Avoid changing money at airports, as thieves could be watching you.
Consult with your hotel manager or tourist information centre about the public transport in your area. Make sure you know what official taxi cabs look like. A thief may pose as a taxi driver to lure you into their car.
Don't share taxis with strangers.
Carjacking is a problem in some cities. When driving, keep all doors locked and windows up. Make sure your boot is locked too.
