Mexican Auto Insurance for San Diego

Mexican Car Insurance for San Diego Drivers Crossing to Tijuana or Baja

Liability-only coverage starts at $23.25 USD per day or $197.00 USD per year, and full coverage runs from about $31.62 USD per day or $438.38 USD per year through Chubb — that is the policy US and Canadian drivers need before crossing at San Ysidro or Otay Mesa, since a home auto policy is not valid liability coverage once you're in Mexico. Most San Diego drivers just need a short pass for a day or weekend in Tijuana, Rosarito or Ensenada, or an annual policy if they cross often.

Do I need Mexican insurance to cross at San Ysidro or Otay Mesa?

Yes. Mexican law only recognizes liability coverage issued by a Mexican insurer, so the policy your US or Canadian carrier sold you back home does not count once you're south of the line. Timi sells a policy issued by Chubb, quoted and bought by chat from your phone in about 2 minutes, with the PDF landing in your email before you reach the booth.

What does a day trip from San Diego to Tijuana or Rosarito need?

All reference totals include Mexican tax and policy fees. Included fees: $18.00 USD for 1 day, 3 days, 7 days, 30 days; $20.00 USD for 90 days; $35.00 USD for 6 months, 1 year. Do not add the fee again. Your exact quote depends on the vehicle, coverage, territory and dates.

Driving from San Diego to Ensenada or Valle de Guadalupe?

The coastal run down to Ensenada or inland to Valle de Guadalupe is a common weekend trip for San Diego drivers, and it's covered by the same Chubb policy — see San Diego to Ensenada for that specific route. Confirm your exact dates and vehicle in the chat so the term on the policy matches your trip.

What do San Diego drivers usually get wrong before crossing?

The most common mistake is assuming a US policy's liability transfers south of the border, or buying at the booth under time pressure instead of ahead of time. The other is picking a one-day rate for a trip that actually runs several days, which ends up costing more per day than a longer term would.

What should I have ready before I reach the border?

Have your driver's license, vehicle registration, and travel dates on hand — the chat asks for these to match the policy to your car and trip. For broader Baja route and border basics, the guides section and Baja California page cover what else to expect once you're past San Ysidro or Otay Mesa. You can also read why Timi before you buy.

Frequently asked questions

Does my US car insurance work if I'm just driving a few blocks into Tijuana?

No. Distance doesn't matter — the moment you cross into Mexico, your US or Canadian liability coverage is not recognized, even for a short hop past the border. You'd need a Mexican-issued policy like the one Timi sells through Chubb, valid from as little as one day.

Can I buy the policy right at the San Ysidro or Otay Mesa border, or should I do it before leaving San Diego?

You can buy it from anywhere with phone signal, including while you're still on the US side, since it's all done by chat with no forms. Buying before you reach the booth means the PDF is already in your email and you're not holding up the line trying to sort it out at the crossing.

Do I need a different policy for Rosarito or Ensenada than for a Tijuana day trip?

No, one Chubb policy covers your vehicle for the dates and term you choose, regardless of how many Baja towns you visit on that trip. Just make sure the term you pick covers the full length of your trip, including the drive back to San Diego.

I'm driving a rental car from San Diego into Mexico — does this apply to me?

The same rule applies: a US rental agreement's insurance typically does not extend as valid Mexican liability coverage, so you'd still want a Mexican policy for the vehicle. Confirm the exact vehicle details in the chat so the policy is issued correctly for that car.
