Tucson is the gateway to Sonora. In about an hour you can be in Nogales, and a few more hours down Highway 15 bring you to Hermosillo, Guaymas and the beaches of San Carlos. Wherever you go, Mexican auto insurance in Tucson should be the first item on your checklist.
Popular Routes from Tucson
- Nogales: shopping, dining and dental or medical visits, just over an hour away.
- Hermosillo: Sonora’s capital, about four hours from Tucson.
- Guaymas and San Carlos: beaches, fishing and sunsets on the Sea of Cortez.
- Bahía de Kino: a quiet fishing town west of Hermosillo.
The Sonora Free Zone
Much of northwestern Sonora is a free zone where foreign-plated vehicles do not need a Temporary Import Permit. Destinations such as Nogales, Hermosillo, Guaymas, San Carlos and Bahía de Kino are within it. If you go farther south or east of Highway 15, you will need a permit from Banjercito. Always confirm the current rules before your trip.
Why You Need Mexican Insurance
Mexico requires liability coverage from a Mexican insurer, and Highway 15 is a busy four-lane toll road with heavy truck traffic. If you have an accident without valid coverage, you may be held until you can guarantee payment for damages.

What to Do If You Have an Accident on Highway 15
Pull over safely, turn on your hazard lights and call 911 if anyone is hurt. Federal highways are patrolled by the Guardia Nacional, who can help. Call the claims number on your policy immediately and wait for the adjuster. Do not sign documents or pay the other party directly.
Crossing Back into Arizona
The return trip can take longer than the drive south, especially on Sunday afternoons and holidays. Check CBP wait times before leaving Nogales, have your passport ready and declare any purchases. If you are carrying food, medicine or alcohol, review CBP’s rules to avoid delays.
Highlights of a Sonora Road Trip
Sonora rewards drivers with variety along a single highway:
- Nogales: pharmacies, dental offices, restaurants and crafts close to the border.
- Magdalena and the Kino Missions: historic churches along the Highway 15 corridor.
- Hermosillo: carne asada, museums and a modern city center.
- San Carlos: Tetakawi mountain, marinas, diving and some of the best sunsets in Mexico.
- Bahía de Kino: a laid-back beach town facing Isla Tiburón.
A single policy covers you for the whole route, as long as the dates match your trip.
Do I need full coverage for a Sonora road trip?
It is recommended for longer drives, newer vehicles and trips with family, because it adds collision, theft and medical coverage.
