U.S. car insurance in Mexico: what's not covered and what the law requires

November 11, 2026. If you're planning to drive to Mexico for Thanksgiving, on November 26, or to spend the winter here, check your insurance before you cross the border. Most U.S. car insurance does not provide valid coverage while you drive in Mexico, according to the guide that U.S. insurer GEICO updated on August 31, 2026. The same guide says Mexican law requires a Mexican auto tourist policy to drive legally in the country and recommends buying it before you reach the border.

Another U.S. insurer, Progressive, explains that Mexican law requires separate liability insurance issued by a company licensed in Mexico. It offers its Texas policyholders physical damage coverage for their own vehicle on occasional trips into Mexico within 25 miles (about 40 kilometres) of the border. That protects your car, not the damage you cause to other people.

What Mexican law says

Article 63 Bis of Mexico's Federal Roads, Bridges and Motor Transport Law (Ley de Caminos, Puentes y Autotransporte Federal) states that every vehicle travelling on federal roads, highways and bridges must carry insurance that covers third parties for damage to their property and persons caused by driving the vehicle, and that the owner is responsible for buying it. Article 74 Bis sets a fine of 20 to 40 days of minimum wage for driving without it, and gives the owner 45 calendar days to buy the policy and show it to the collecting authority to have the ticket cancelled.

Expansión calculates that fine in UMA, Mexico's unit of measure for fines, and puts it at 2,346.20 to 4,692.40 pesos, or about 126 to 251 dollars at the Bank of Mexico FIX exchange rate of November 10, 2026 (18.6678 pesos per dollar), the latest published when this note was written.

What happens if you crash on a federal highway

Since May 26, 2026, Mexico's National Guard has been applying the amendments to the Traffic Regulation for Federal Highways and Bridges, according to El Financiero. The decree describes what follows a crash:

• If there is only property damage and the drivers are not under the influence of alcohol or drugs, they can agree on the repair or payment on the spot and, if they ask, the National Guard draws up a settlement record, an acta-convenio (article 185).
• If a settlement is not possible or the drivers don't agree on who is responsible, the National Guard refers them to the appropriate authority and the vehicles go to licensed impound lots (article 187).
• In certain cases listed in the regulation, the National Guard takes steps to keep the driver, companions or passengers and the vehicle in its custody, and informs the investigating authority (article 209).
• When a violation leads to a vehicle being taken off the road and it goes to the impound lot because it has no policy or the policy doesn't apply, the driver or owner must pay or guarantee the fines imposed to get it released (article 204).

A Mexican policy is built for this. The tourist auto insurance page of MAPFRE, for example, lists among its coverages legal defence for the driver from the start to the end of a criminal proceeding, including steps to obtain release on bail, and medical expenses for occupants, and says it can be bought for one day up to one year. Check in the policy terms which of them apply to the plan you choose.

Why it's not enough that the other driver is insured

Only 30% of the vehicles on Mexico's roads have any policy, according to an estimate by the Mexican Association of Insurance Companies (AMIS) cited by Animal Político in July 2026. If an uninsured driver hits you, in practice you'll depend on the coverages you bought yourself, such as physical damage or medical expenses for occupants.

If you live in Mexico with a foreign-plated car

If you spend the season here or you're a resident driving a car with U.S. or Canadian plates, at 1SEGUROS we can quote you auto insurance for foreign plates with Mexican insurers. If your car already has Mexican plates, we offer national auto insurance, with full, limited or liability-only coverage.

Before you cross the border

1. Buy the Mexican policy before you arrive. That's what GEICO recommends.
2. Check what it includes, not just the price. Ask about legal defence, medical expenses for occupants and damage to your own car, in addition to liability.
3. Check the temporary import permit. According to Progressive, you need one if you drive beyond the border free zone.
4. Keep the policy handy. We recommend having your insurer's claims number and checking with it before you sign any settlement.

If you'll spend weeks here, also review your travel insurance: the medical coverage in an auto policy, when it exists, has limits.
