Driving to Mexico or Canada: what your US car insurance covers and what you need to add

Does US car insurance work in Mexico?

Near the border in San Diego, Arizona or Texas, a trip south can feel routine. For insurance it isn't: your policy was written for US state laws.

What Mexican law requires

Mexico's federal roads law, the Ley de Caminos, Puentes y Autotransporte Federal, says every vehicle on federal roads, highways and bridges must carry insurance that protects third parties against damage to their property and persons. That rule, Article 63 Bis, was added on May 21, 2013 and puts the duty to buy coverage on the owner. It refers to all vehicles and makes no exception for foreign plates.

Under Article 74 Bis, driving on a federal road without that insurance can bring a fine, which the law expresses as 20 to 40 days of minimum wage. The fine is canceled if the owner buys a policy and shows proof within 45 days.

Why your US policy is not enough

• The Texas Department of Insurance (TDI) says Mexico doesn't recognize American auto policies and that drivers heading into Mexico should buy a Mexican liability insurance policy.
• The NAIC's consumer guide says that to drive into Mexico you'll need to buy Mexican auto insurance.
• The US Embassy in Mexico is blunt: "Your U.S. insurance is not sufficient." You need a separate policy.

The gap is about liability. Liability coverage pays others when you cause a crash, and in Mexico that duty must be met by a policy Mexican authorities accept, whatever your US limits.

Buying Mexican liability insurance

The US Embassy notes that many companies sell short-term "tourist" policies. Mexico's financial consumer agency, CONDUSEF, advises checking that an insurer is duly authorized by Mexican authorities. When you compare policies, check:

• Dates. Every day you'll be in Mexico, including the drive back to the border.
• Car and drivers. The right VIN and plate, and everyone who will drive.
• Liability limits. The law sets a floor; higher limits protect you more if you injure someone.
• Your own car. Liability alone won't repair or replace it, so ask about physical damage and theft coverage.

TDI notes that some Texas agents sell Mexican policies. StateCover Guide doesn't recommend specific insurers or brokers.

What a US policy's Mexico coverage may or may not do

Some US insurers offer an endorsement for short trips into Mexico. TDI warns it might not meet Mexico's legal requirements. Wording varies widely, but in general terms an endorsement may extend some protection for your own car, while a Mexican policy is what satisfies Mexican liability law.

Before relying on an endorsement, ask your insurer in writing which coverages apply in Mexico, any distance or day limits, and how you'd report a claim from there.

The border zone and the temporary vehicle import permit

Insurance and the vehicle permit are separate requirements. The temporary vehicle import permit, often called a TIP, depends on where you go. The US Embassy says a US-registered car needs one for most of Mexico, but not for the Baja California Peninsula, the Sonora Free Zone, Quintana Roo or the Border Zone, generally within about 12 miles of the US border. Mexico's embassy in Canada says the border strip extends 21 km into Mexico.

You can get a TIP at CIITEV modules at major crossings, or request it on the Banjercito website 10 to 60 days before you enter. The Consulate of Mexico in Denver lists these costs:

Pay by Visa or Mastercard in your own name; the deposit goes back to that card. The permit lasts for your authorized stay. On the way out, cancel it at the Banjercito office at the border: the US Embassy says skipping this forfeits the deposit and may keep the car out of Mexico in future. Driving without a required permit can mean steep fines and impoundment. For a financed or leased car, the consulate accepts a recent financing contract with an authorization letter, or a leasing contract in your name.

Does US car insurance work in Canada?

Usually, yes. The NAIC says your auto insurance will cover you in Canada, and TDI lists accidents in other states and Canada among the things most policies cover. The US State Department says US auto insurance is accepted for tourists and proof of insurance is required.

Policies often adjust to local rules: New York's Department of Financial Services says a New York policy covers you at the higher limits a Canadian province requires. Check your own policy's out-of-state clause.

Proof of insurance and the Yellow Card

The Canadian Council of Insurance Regulators (CCIR) explains that US insurers can file a Power of Attorney and Undertaking, agreeing to meet the minimum liability limits of the province or territory where an accident happens. Those insurers can issue the Canada Non-Resident Inter-Province Motor Vehicle Liability Insurance Card, known as the Yellow Card, as evidence of coverage if police stop you or you crash. CCIR says the card isn't required in every province.

Ontario's insurance regulator accepts, for drivers from US states, a document from the insurer or state government showing the car is insured under that state's laws. Ontario also tells visitors to carry the original, or an exact copy, of the vehicle's ownership permit.

Provincial minimums differ

Canada has no single national minimum. CCIR says the compulsory third-party liability limit is 200,000 CAD in most provinces and territories; Nova Scotia's minimum is higher, as the table shows. Amounts are in Canadian dollars.

In British Columbia, ICBC says tourists can drive on their existing insurance for up to 6 months with a valid out-of-province licence. If your US limits are below a province's minimum, ask your insurer to confirm in writing that it will meet that province's requirement.

Quebec's public plan for injuries

Quebec's public plan, run by the Société de l'assurance automobile du Québec (SAAQ), compensates people injured in road accidents regardless of fault, and the SAAQ says its no-fault principle bars court proceedings against another road user. Private insurance handles property damage.

For non-residents in a vehicle registered outside Quebec, the SAAQ pays benefits in inverse proportion to their share of responsibility. Its example: a non-resident who bears 20% of the responsibility gets 80% of the plan's benefits. Agreements with Ontario, Manitoba and Alberta can take precedence for those provinces' residents. The SAAQ also says it may seek reimbursement from you for benefits paid to a victim if you were responsible.

Licence rules for visitors

The State Department says US driver's licenses are valid for visitors to Canada, and provinces set time limits, as the table shows. Quebec notes that an international driving permit can only be issued in the country that issued your licence, so get one before you leave.

Rental cars in Mexico and Canada

• Renting in Canada. Your policy's rental coverage may extend to Canada. New York's regulator, for example, says a New York policy makes the rental company's collision damage waiver unnecessary for rentals of 30 days or less in the US, its territories and possessions, or Canada. Note that rental reimbursement is different: it pays for a substitute car after a covered claim, not for damage to a rental.
• Renting in Mexico. Wisconsin's consumer protection agency recommends taking the rental company's waiver in a foreign country, because your personal auto insurance may not be valid outside the US. Ask what Mexican liability coverage comes with the car.
• Taking a US rental into Mexico. Read the rental agreement first; it may forbid the trip. You still need Mexican liability insurance and, beyond the border region, a TIP.
• Credit card benefits. Read your card's guide to benefits for any country limits before you rely on it.

Before you cross: a step-by-step checklist

1. Call your US insurer. Ask which coverages apply in Canada and Mexico, and get the answers in writing.
2. For Canada, get proof ready. Ask for a Yellow Card if your insurer issues one, and keep it with your insurance card and registration.
3. For Mexico, buy a Mexican liability policy from an authorized insurer, covering your whole stay and every driver.
4. Decide how to protect your own car. Compare physical damage coverage on the Mexican policy with any endorsement your US insurer offers.
5. Check whether you need a TIP. Beyond the border zone, Baja California, Quintana Roo or the Sonora Free Zone, apply online or at the border with a card in your name.
6. Pack documents. A passport, passport card or other document US Customs and Border Protection accepts at land crossings, plus your license, registration and printed insurance papers. Service members, see car insurance for military members.
7. Check licence and visit-length rules for each province on a long stay.
8. Ask your lender or leasing company whether the trip is allowed.
9. Cancel the TIP when you leave Mexico at the Banjercito border office, and keep the receipt.
