It's about **177 miles (3 hours)** south of the Nogales, Arizona border on Federal Highway 15 — and thanks to Sonora's "Only Sonora" program, you won't need the federal vehicle permit required to drive deeper into Mexico. Here's how to plan the trip. ## The route: Nogales to Hermosillo - **From Tucson:** about 1 hour to the Nogales crossing, then 3 hours on Highway 15 — roughly 4 hours total. - **From Phoenix:** about 3 hours to Nogales, then 3 hours south — a long but very doable day, or split with an overnight. - **Highway 15** is a modern four-lane toll road (cuota). Keep some pesos or USD for the toll booths. ## The "Only Sonora" program — no vehicle permit Normally, driving a foreign-plated car into mainland Mexico requires a Temporary Vehicle Import Permit (TIP) with a refundable deposit. Sonora is different. Under the **"Only Sonora" (Sonora Solo)** hassle-free program, visitors driving to destinations like Hermosillo, San Carlos and Guaymas do **not** need a federal TIP. This removes the biggest headache of driving into Mexico. A note on the details: a "Sonora Only" vehicle permit (about $30-$50 USD) can be required if you drive east of Highway 15 or south of Empalme. For a straight trip down Highway 15 to Hermosillo you generally stay within the free zone. Rules change, so **always confirm current requirements with Banjercito before you travel.** ## Documents you'll need - **Valid US passport** (passport book or card). - **FMM tourist card** — issued at the border; required for visits beyond a short stay or distance. - **Mexican auto insurance** — your US policy won't cover you in Mexico; buy a short-term Mexican policy online before you go. - Vehicle registration and a valid driver's license. ## Border crossing tips Cross on a weekday morning for the shortest waits and the easiest paperwork. Fill your tank on the US side, carry pesos for tolls, and drive Highway 15 in daylight your first time.
