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.
Start here: the four essentials before you cross
- 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.
- Travel documents. A US passport or passport card to get back across the border.
- FMM tourist permit if needed – see when it applies for Baja.
- Pesos or a card for toll roads and fuel.
Border crossing logistics
Which crossing to use, how long the wait will be, and how to speed it up.

Sonora coast: Arizona to the Sea of Cortez
Heading past the border zone to mainland Sonora – the beaches, the route, and the permits.
Pacific coast: Puerto Vallarta & Riviera Nayarit
The long mainland drive down the Pacific – Banderas Bay and the Nayarit beach towns.
Inland Jalisco: Guadalajara, Tequila & Lake Chapala
Heading inland from the coast – Mexico’s second city, agave country, and the expat lakeside.
Costalegre coast & Colima: Manzanillo and the volcano
Further down the Pacific – the quiet Costalegre beaches, the port of Manzanillo, and volcano country.
Bajio highlands: San Miguel, Guanajuato & Queretaro
Mexico’s colonial heartland and expat country – the central highlands by car.
Texas border crossings & the northern route
Driving in from the east – the Laredo gateway and the central corridor to the Bajio.
Mexico City & the Highway 57 terminus
The end of the central corridor – the capital, its driving rules, and the road in.
South of the capital: Puebla, Oaxaca & the coast
Beyond Mexico City – colonial Puebla, the Cholula pyramid, Oaxaca and its Pacific beaches.
Mexico’s far reaches: the Sierra, Chiapas & the Yucatan

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.
