Phoenix is 110 miles north of Tucson, a drive that takes about an hour and 40 minutes heading west on I-10. The international border between Nogales, Arizona, and neighboring Nogales, Sonora is 60 miles away, which is roughly a one-hour drive south via I-10/I-19. Drivers looking to travel deeper into Mexico beyond Nogales will need to carry a Mexico-specific auto insurance policy.
