🛑 Driving to Baja? The Truth About the FMM, New Checkpoints, and What the Law Actually Says 🇲🇽

If you follow any Baja travel forums or Facebook groups, you have likely seen the recent explosion of comments regarding INM (Instituto Nacional de Migración) checkpoints and "new rules" for traveling in Baja.

As your local insurance experts based here in San Felipe, we want to cut through the noise. Whether you are a first-time visitor or a veteran traveler who has been driving down for 30 years, understanding the difference between customary practice and legal requirements is essential to avoid fines, delays, or deportation.

Here is everything you need to know about the FMM (Forma Migratoria Múltiple) right now.

What is the FMM?

The Forma Migratoria Múltiple is your official tourist permit. It is crucial to understand the difference between Customs (Aduana) and Immigration (Migración):

• Aduana (The Car): Baja is a "Free Zone," so you generally do not need a Temporary Import Permit (TIP) for your vehicle unless you go to the mainland.

• Migración (The Person): There is no Free Zone for people. Every non-Mexican citizen entering Mexico is legally required to have a valid passport and an FMM tourist permit.

The "Law vs. Custom" Confusion

This is the most controversial topic among expats. You might hear people say: "I have driven down for 20 years, never stopped for a permit, and never had an issue."

This creates a false sense of security. Here is the reality:

• The Custom: For decades, enforcement in Baja was lax. It was easy to drive through without stopping, creating a "custom" of non-compliance.

• The Law: The requirement to have an FMM has always existed. It is not a new rule. The only thing that has changed is the enforcement.

Just because it wasn't enforced strictly in the past does not mean it wasn't required. Relying on "how we used to do it" is no longer a valid legal strategy when facing a federal agent at a checkpoint.

Do I Need to Stop at the Border?

Yes. Even if you fill out the FMM form online and pay for it in advance, it is not valid until it is stamped by an Immigration Officer at the border. If you are stopped at a checkpoint south of the border and you have the printed receipt but no stamp, it is invalid. You must stop at the border crossing (El Chaparral, Otay, Mexicali East/West) to get that stamp.

Validity: One Entry or Multiple?

This is another common point of confusion.

• The 7-Day FMM: Usually free. It is for a single trip.

• The 180-Day FMM: Costs approx. $40 USD (adjusted annually).

Technically, the FMM is a single-entry document that is supposed to be surrendered when you exit Mexico. When you re-enter, you are supposed to get a new one.

However, many travelers treat the paid 180-day FMM as a "multiple entry" visa. While some agents may wave you through with a valid date, strictly legally speaking, if you leave the country, that permit ends. If you want guaranteed peace of mind, always ask the agent stamping your passport: "Is this valid for multiple entries, or must I surrender it when I leave?"

Summary Checklist for a Stress-Free Trip

1. Passport: Ensure it is valid for at least 6 months.

2. FMM: Stop at the border, pay the fee (if staying >7 days), and get it stamped.

3. Auto Insurance: Your US or Canadian insurance is rarely valid in Mexico. You need Mexican liability insurance by law.

Don't let a missing piece of paper ruin your Baja adventure. Compliance is easy, affordable, and gives you peace of mind.
