Who Pays When the Driver Who Hit You Has Mexican Insurance
A driver from Mexico who hits you in San Diego may or may not have insurance that counts in California.
A Mexican policy can satisfy California's financial responsibility law for a car registered outside California when the insurer has filed a power of attorney with the DMV, under Vehicle Code § 16056(b).
A policy that does not extend to driving in the United States, or whose insurer denies the claim, leaves the car uninsured under California's definition.
Then your own uninsured motorist coverage is the route to compensation.
Trucks from Mexican carriers follow a separate set of federal insurance rules.
More than 990,000 trucks entered the United States through Otay Mesa in 2025.
After a crash near the border, the other driver's insurance card and registration are the documents that answer who pays.
Crashes With Drivers From Mexico at a Glance
- A non-admitted Mexican insurer's policy can count for a car registered outside California if the insurer filed a power of attorney with the DMV
- A policy that does not apply to the crash, or a denied claim, makes the car uninsured for UM purposes
- Mexico-domiciled trucks must carry U.S.-authorized insurance of at least $750,000 for general freight
- Serving a lawsuit on a defendant in Mexico runs through the Hague Service Convention, with Spanish translations
- Two years to file the injury claim, and two years to protect your own uninsured motorist claim
Is Mexican Car Insurance Valid in California?
California's default rule is that an insurance policy proves financial responsibility only if the insurer is admitted to do business in California. Under § 16056(b), a non-admitted insurer's policy counts for a vehicle registered outside the state if the insurer "executes a power of attorney authorizing the department to accept service on its behalf of notice or process."[1]
The minimum limits are the same as for any California policy issued or renewed since January 1, 2025: $30,000 per person and $60,000 per crash for injuries, and $15,000 for property damage.
Three things decide whether a Mexican insurance card means coverage: whether the policy reaches driving in the United States, whether the insurer filed with the DMV, and whether it accepts the claim. A photo of the card, the policy number, and the insurer's name taken at the scene lets each one be checked.
There are two workable answers when the other driver is insured in Mexico. Either the policy covers the crash and pays, or it does not and your own uninsured motorist coverage becomes the claim. A tractor-trailer from a Mexican carrier has to prove U.S. insurance before it crosses at Otay Mesa, and the pickup in the next lane may carry a policy California does not recognize. Good legal representation will identify and run down what coverage is available without wasting two years running down the options.
What Happens When the Mexican Insurer Denies the Claim
Insurance Code § 11580.2(b) defines an uninsured motor vehicle as one with "no bodily injury liability insurance or bond applicable at the time of the accident," or one whose insurer denies coverage or will admit it only "conditionally or with reservation."[2] Nothing in the definition depends on where the insurer is based.
- A Mexican policy that covers the crash and is honored: the claim goes against that policy, and your uninsured motorist coverage does not
- A policy limited to driving in Mexico: the car is uninsured for this crash, and your own UM coverage can pay
- An insurer that denies the claim or reserves its rights: the statute treats the car as uninsured
No published California appellate decision has applied this definition to a Mexican policy, so the argument rests on the statute's text. Your own insurer will look for the same facts, which is another reason to collect the other driver's documents early.
Uninsured motorist coverage has its own deadline and rules, explained on our page about uninsured motorist and hit-and-run claims in California.
The Federal Rules for Trucks From Mexican Carriers
A commercial carrier based in Mexico needs a USDOT number, an FMCSA-assigned MX number, and a Certificate of Registration before its trucks enter the United States, either for work inside the border commercial zones or, with long-haul authority, for international freight beyond them.[3]
- A U.S.-authorized insurer: federal rules accept insurers authorized in a U.S. state, U.S.-authorized surplus lines insurers, and Canadian insurers, and do not list Mexican insurers[4]
- At least $750,000 in liability coverage for for-hire general freight in vehicles of 10,001 pounds or more, and $1 million or $5 million for hazardous materials[5]
- Proof aboard every truck: an English-language MCS-90 or MCS-82 endorsement, without which the vehicle "shall be denied entry into the United States"[6]
- A U.S. process agent named on a BOC-3 filing, so the carrier can be served without going through Mexico
A commercial-zone carrier may buy that coverage in periods as short as 24 hours, so the policy in force on the day of the crash is what to identify.

How Many Trucks Cross at Otay Mesa Each Year
The Bureau of Transportation Statistics counts vehicles entering the United States at each port. Otay Mesa, the commercial crossing in San Diego's South Bay, was second on the U.S.-Mexico border in 2025, behind Laredo's 2,945,388 trucks.[7]
| Year | Trucks entering at Otay Mesa |
|---|---|
| 2023 | 1,034,188 |
| 2024 | 1,059,759 |
| 2025 | 990,111 |
| 2026, January through September | 744,037 |
These are northbound entries only; the government does not count trucks leaving the country. San Ysidro, a few miles west, took in about 33 million people in 2025 by car, on foot, and by bus or train, more than any other land port in the United States.
Three Versions of the Same Crash on Interstate 805
A driver from Tijuana runs a red light at an I-805 off-ramp in Chula Vista and hits your car. Who pays depends on the driver's coverage.
If the driver's Mexican insurer covers U.S. driving, has filed a power of attorney with the DMV, and accepts the claim, the claim goes against that policy, up to its limits. If the policy covers driving in Mexico only, the car is uninsured for this crash, and your own uninsured motorist coverage pays up to your limits. If the vehicle was a tractor-trailer from a Mexican carrier operating legally, the claim goes to the carrier's U.S.-authorized insurer, with at least $750,000 behind it.
The example shows how the rules sort a crash; the outcome of any real claim depends on its own facts.
Suing a Driver or Trucking Company Based in Mexico
Mexico joined the Hague Service Convention in 1999, effective in 2000, and its declarations require a Spanish translation of the documents and reject service by mail or other direct channels.[8] Service goes through Mexico's Central Authority at the Ministry of Foreign Affairs.
A Mexican motor carrier with U.S. authority can usually be served through its BOC-3 process agent in the United States instead. Collecting a judgment from assets in Mexico is a separate proceeding in the Mexican courts, which is one reason the insurance questions above come first.
What a Crash With a Driver From Mexico Can Be Worth
The damages follow California law whoever the defendant is: medical bills, lost income, and pain and suffering, reduced by any share of fault that is yours.
- The policy limits, which can set the practical ceiling against an individual driver
- Your underinsured motorist coverage, when the other driver's limits are lower than your own coverage
- Your own insurance status, since Proposition 213 bars pain-and-suffering damages for a driver who was uninsured at the time, under Civil Code § 3333.4[9]
The Proposition 213 rule and its exceptions are explained on our page about Proposition 213 and uninsured drivers.
Two Years to File, and the Same Two Years for Your UM Claim
A California injury lawsuit must generally be filed within two years under Code of Civil Procedure § 335.1, and that applies to a driver from Mexico like anyone else.[10]
Your own uninsured motorist claim has a separate requirement. Within two years of the crash, you must settle it, file suit against the uninsured driver, or formally begin arbitration with your insurer, under Insurance Code § 11580.2(i). A pending claim with the other driver's Mexican insurer does not stop that clock.
A crash caused by a road defect or involving a public vehicle adds the six-month government claim, covered on our page about San Diego claim offices and courts.
