Can I cross with a rental car?

Yes, but you need written permission from the rental company specifically authorizing Mexico travel. Most US rental companies don't allow this, so check your contract carefully.

How long can I keep my car in Mexico?

Tourist vehicles can stay up to 180 days. You must exit with your vehicle before the permit expires or face hefty fines and potential vehicle seizure.

What if I lose my vehicle import paperwork?

Go immediately to the nearest Banjercito office with your passport and vehicle registration. They can issue replacement documents, but it's a time-consuming process that can take several days.

Do I need an International Driving Permit?

Not required but recommended. A valid US driver's license works for tourist stays, but an IDP can help with police interactions and car rental if needed.

How to Cross the US-Mexico Border by Car

Cross at an official port of entry with your passport, vehicle registration, and Mexican auto insurance. Get your tourist card (FMM) stamped at immigration, declare your vehicle at customs, and pay the temporary import permit fee if traveling beyond the border zone.

Get Mexican auto insurance. Buy Mexican liability insurance online or at the border. US insurance doesn't cover you in Mexico. Expect to pay $25-50 per day depending on coverage. Progressive, AAA, and Sanborn's are reliable options.
Prepare your documents. Bring your passport, driver's license, vehicle registration, and title (if you own the car). If the car isn't yours, bring a notarized letter from the owner authorizing you to drive it in Mexico.
Choose your crossing point. Major crossings like San Diego-Tijuana and El Paso-Juárez have longer waits but more services. Smaller crossings like Nogales or Brownsville move faster. Check current wait times on CBP's website or mobile app.
Cross into Mexico. Follow signs for 'Mexico' and 'Turismo.' Stop at the immigration booth first to get your tourist card (FMM) stamped. This is mandatory even if you're just visiting border cities.
Handle vehicle importation. If traveling beyond the 'free zone' (roughly 12-16 miles from the border), stop at the Banjercito office. Pay the temporary vehicle import fee ($51 USD plus deposit based on vehicle value). Keep all paperwork - you'll need it to exit Mexico.
Go through customs. Press the button at the traffic light system. Green means go, red means inspection. If selected for inspection, remain calm and cooperative. Most inspections are routine and take 10-15 minutes.
