Cheapest Mexican car insurance: what you are really comparing

The short version

The cheapest real number we can show you is $26.69 USD for one day of Chubb liability-only in the border-states territory ($26.97 for all of Mexico), measured 2 September 2026. Of that, $18 is a fixed policy fee Chubb charges on every policy — which is why a one-day policy "does not get cheaper" whoever sells it.

Per day, the cheapest Mexican insurance is the longest one: the annual liability policy costs $228.52 for all of Mexico ($212.63 border states), about $0.63 per day, and pays the fee once.

"Cheapest" comparisons usually mix three different products: liability-only (from $26.97/day), full coverage (about $37/day for a typical car), and policies with lower liability limits. Compare the same limits, the same territory and the total with fees.

The insurer on the policy is what you are buying. Every valid Mexican tourist policy is issued by a Mexican insurer; a lower price with a weaker insurer or a lower limit is not a bargain when the claim happens in Mexico.

Where we are not the cheapest: for a single one-day trip the fee dominates and every seller lands near the same number; for someone who wants an agent face to face or pays cash, a traditional broker fits better.

Direct answer with the number: the cheapest real price we can show you is $26.69 USD for one day of Chubb liability-only in the border-states territory ($26.97 for all of Mexico), measured 2 September 2026 — and $18 of it is a fixed policy fee. Per day, the cheapest Mexican insurance is the longest one: the annual liability policy costs $228.52 for the year, about $0.63 a day. Everything else people call "cheapest" is a comparison between different products.

The fee that flattens every one-day price

Chubb charges $18 USD per policy on daily and 30-day plans ($20 on 90 days, $35 on 180 days and annual), whatever the length. A one-day policy is mostly fee; a one-year policy is mostly coverage. No seller can discount a fee they do not set — which is why one-day quotes cluster near the same number on every site.

USD, Chubb Tourist Auto via Timi, $100,000 USD liability + $2,000 USD medical, IVA included. Three separate one-day trips cost $80.91 and pay the fee three times; the 7-day policy at $63.51 covers a whole week for less. That single fact settles most "cheapest" arguments — the full math is in is annual Mexican car insurance worth it?.

Three things "cheapest" usually mixes up

Liability-only vs full coverage. $26.97 a day buys what the law requires; about $37 a day also covers your own car for damage and theft. Different products, not a discount.
Liability limits. A quote with a lower liability limit is cheaper for a reason. Ours defaults to $100,000 USD; compare like with like — see coverage comparison.
Territory. Border states (Baja, Sonora, the northern strip) is a few dollars cheaper than all of Mexico. Fine for Rocky Point or Ensenada; wrong for Mazatlán.

What you are actually buying

By Mexican law only a Mexican insurer can issue the policy, whoever sells it. So the price you compare is attached to an insurer, a claims network and a set of limits. Chubb has been the number-one tourist-auto insurer in Mexico for more than ten consecutive years and handles claims through Chubb México 24/7 — that is the insurer behind every Timi policy, and it is why we do not chase the last dollar on a one-day pass.

Where we are not the cheapest — said plainly

For one single day, everyone lands near $27 and there is nothing to win. If you want a person across a desk, a drive-through stand at the border when you have no signal, or to pay cash, a traditional seller fits better. For a personal car, SUV, pickup, motorcycle or RV on real trips — a weekend, a week, a month, a snowbird season — the chat at timi.mx/tourist gives the real number in about 3 minutes, before you type an email.

Frequently asked questions

What is the cheapest Mexican car insurance you can buy?

The lowest real price in our quoter on 2 September 2026 was $26.69 USD for one day of Chubb liability-only coverage ($100,000 USD liability + $2,000 USD medical) in the border-states territory, $26.97 for all of Mexico. Per day, though, the cheapest policy is the annual: $228.52 for the year, about $0.63 a day.

Why does a one-day policy never go much below $27?

Because Chubb charges a fixed $18 USD policy fee on every Tourist Auto policy, regardless of length. On a one-day policy the fee is two thirds of the price; the coverage itself is a few dollars. No seller can discount a fee they do not control, so one-day prices cluster around the same figure everywhere.

Is liability-only the cheapest option?

It is the cheapest legal option: Mexican law requires third-party liability from a Mexican insurer, and that is what liability-only provides. It does not pay for your own car. Full coverage (liability + own-damage + theft) costs about $37 USD per day or $531 per year for a typical car — a different product, not a more expensive version of the same one.

How do I compare two quotes fairly?

Same liability limit (ours is $100,000 USD), same medical limit ($2,000 USD), same territory (border states vs all of Mexico), same number of days, and the total including fees and tax. Then look at the insurer named on the policy and at how claims are handled in Mexico. A quote missing any of those is not comparable.

Is the border-states territory worth choosing?

If your whole trip stays in Baja, Sonora and the northern border states, yes: $26.69 vs $26.97 for a day and $212.63 vs $228.52 for the year. If there is any chance you drive farther south, the all-of-Mexico policy is the safe choice — a policy cannot be re-territoried from the road.

When is Timi not the cheapest?

On a single one-day trip, the fixed fee makes every seller land near the same price and there is little to win. If you want to sit with an agent, pay cash, or insure a fleet or a commercial vehicle, a traditional broker fits better. For a personal car on real trips, the annual at $228.52 is hard to beat per day.
