Arizona's track record in terms of crime is not unlike that of other U.S. states, if a little higher than average in Phoenix and Tucson. In these big cities you should take the same precautions you would anywhere—be aware of what's going on around you, stick to well-lighted areas, and quickly move away from any situation or people that might be threatening. In both of these cities it's easy to find yourself driving into a less-than-savory neighborhood with little notice; if you feel uneasy about your surroundings, turn around and go back the way you came.
Check the U.S. government travel advisory before you plan a trip to the Mexico border towns. Visitors should take extra precautions.
