Car driving the scenic Baja California coastal highway from San Diego into Mexico at golden hour

Driving from San Diego into Mexico is one of the easiest international road trips in the country – tacos in Tijuana, wine in Valle de Guadalupe, beaches in Rosarito and Ensenada are all a short drive away. But there are a few things every driver needs to get right before crossing: the right border, the right paperwork, and the right insurance. This complete guide walks you through all of it.

Quick answer: Before you cross, line up four things: 1) Mexican auto insurance (required by law), 2) your passport or passport card, 3) an FMM tourist permit if your stay runs over 7 days, and 4) pesos or a card for tolls and gas. Of these, insurance is the one you need on every trip, no matter how short.

Start here: the four essentials before you cross

  1. Mexican auto insurance. Mandatory for every driver. Your US policy will not cover you. Here is why, and you can get a quote in two minutes.
  2. Travel documents. A US passport or passport card to get back across the border.
  3. FMM tourist permit if needed – see when it applies for Baja.
  4. Pesos or a card for toll roads and fuel.

Frequently asked questions

Do I need insurance to drive from San Diego to Mexico?

Yes. Mexico requires liability coverage from a Mexican-licensed insurer for every driver, and your US policy does not qualify – even for a short trip to Tijuana. You can get covered online in minutes.

Which border crossing is best for driving into Tijuana?

San Ysidro is the busiest and closest to downtown Tijuana and is open 24/7, making it the default for most travelers. Otay Mesa is better for east Tijuana and sometimes has shorter waits, and Tecate is the quietest, ideal for wine country and eastern Baja.

Do I need a permit to drive in Baja?

No vehicle import permit (TIP) is needed anywhere in Baja. You may need an FMM tourist permit if you stay longer than 7 days or travel deep into Mexico. Auto insurance, however, is always required.
