Before you go to Baja.
The one non-negotiable: valid Mexican auto insurance — get a quote →
The short version.
If you read nothing else, read these three. They’re the questions every first-timer asks — and the ones people most often get wrong.
No.
The Baja peninsula is a free zone — no Temporary Import Permit required. You only need one to drive to mainland Mexico.
Yes.
US and Canadian policies aren’t valid in Mexico — even ones claiming Mexico mileage. A Mexican liability policy is the law.
~$300 / person
Of merchandise, by land — plus all your personal belongings. The figure rises to $500 in holiday periods.
Mexican auto insurance.
There’s one thing you cannot skip. Drive uninsured after an accident in Mexico and you can be detained until liability is sorted — settle this first.
You must carry a Mexican auto policy.
US and Canadian policies aren’t recognized — even ones claiming ‘X miles of Mexico coverage.’ Minimum is liability-only; most members add full coverage. Get a quote in about 60 seconds, Chubb-backed.
Do you need a vehicle permit?
This is the question travelers over-worry most. The answer depends entirely on one thing: are you staying on the Baja peninsula, or driving across to mainland Mexico?
No permit needed.
The Baja peninsula sits in Mexico’s free zone — drive the whole peninsula, top to bottom, with no Temporary Import Permit at all.
You'll need a TIP.
A TIP is valid up to 6 months with multiple entries. Turn it in before you leave Mexico and before it expires.

Renting a car?
Confirm coverage before you book

What you can bring into Mexico.
Your personal belongings cross duty-free — bring what you’ll reasonably use. The limits only kick in on merchandise: new goods, gifts, and things you’ll leave behind.
≈$300 / person
Standard allowance
Families arriving together in the same vehicle can combine their allowances. Keep your receipts. Rises to ≈$500 / person during Paisano holiday periods.
Personal belongings & luggage
Duty-free. Bring what you’ll reasonably use — clothes, toiletries, camping gear, fishing rods, electronics for personal use, and medical devices. No need to enumerate every gadget.
Merchandise over your allowance
Declaration lane · ~16% duty. Over your per-person allowance, use the declaration lane and pay ~16% duty. Over $3,000, a Mexican customs broker is required.

Traveling with minors.
Kids need their own paperwork — and if they’re not traveling with both parents, one document matters more than the rest.
Proof of citizenship for every child
Minors need proof of citizenship, and kids over 2 need an FMM — so carry a passport or passport card for each child.
A notarized consent letter, if traveling without both parents
A minor traveling without both parents/guardians needs a notarized consent letter authorizing the trip — means of travel, destination, dates. Issued outside Mexico, it should be translated to Spanish and apostilled.
Use official guidance — not a lead-gen form site
Confirm requirements and download templates from the Mexican consulate or the US State Department.
Money & connectivity.
Two five-minute jobs that save real headaches down the peninsula — sort them before you cross.
Tell your bank you'll be in Mexico
Ask about no-fee ATM partners in Baja, and carry some pesos for tolls, tips, and small vendors.
Set up phone & data before you cross
Telcel has the best remote coverage, and tourist eSIMs install before you leave.
Local customs & etiquette.
Sixty years of members have learned the small courtesies that make Baja warmer. A few go a long way.
Drink bottled water
Outside major resorts and restaurants — including for brushing teeth and ice. Disinfectant drops for washing produce are sold in grocery stores.
The bill won't come until you ask
Rushing it is considered rude. Catch the server’s eye — “La cuenta, por favor.”
A little Spanish goes far
Greet with “¿Cómo está?” — and “por favor” / “gracias” are always appreciated.
Fixed prices in stores; haggle at the stalls
Prices are set in shops. Bargaining is fine at outdoor stalls and markets — keep it good-natured.
