Direct answers to your Mexico questions

If you're driving a vehicle into Mexico, yes — your US or Canadian auto policy is not recognized south of the border, and you can be detained after an accident without a Mexican policy. Travelers without a vehicle should consider travel medical for healthcare emergencies abroad.

Almost never. Most US health plans either don't cover care abroad or pay only emergency-room costs at out-of-network rates. A short-term travel medical plan is usually the simplest fix.

Auto insurance for a one-day cross-border trip typically runs $15–$30 for liability-only and $30–$60 for full coverage. Travel medical for a one-week trip is usually $20–$60 depending on age and limits. Get an instant quote for your exact dates.

Online quotes are real-time. Most travelers complete the buy and download the policy in under five minutes. The policy is valid the moment you cross the border with the dates you selected.

Yes for most products — log in, extend the dates, and pay online. Don't let the policy lapse: a gap of even one day means you're driving uninsured.

Yes. US and Canadian citizens need a valid passport book to enter Mexico by air. By land, a passport book or passport card works. Children under 16 traveling by land need a passport or birth certificate.

The FMM (Forma Migratoria Múltiple) is Mexico's tourist permit. It's required for stays beyond the 'border zone' or longer than 72 hours. You can fill it out online before your trip or at the border crossing.

Yes — pesos go further than US dollars almost everywhere outside tourist zones. Pull pesos from a bank ATM (better rate than airport kiosks). Carry a mix; many places near the border accept dollars but offer a worse exchange rate.

Stick to bottled or filtered water. Reputable restaurants use purified ice. Brushing teeth with tap water is generally fine in tourist zones, but bottled is safer if your stomach is sensitive.

Use ATMs inside banks, hotels, or grocery stores during the day. Avoid stand-alone ATMs on the street, especially at night. Cover the keypad and check for skimmers.

SENTRI is a CBP trusted-traveler program for frequent crossers — pre-vetted, dedicated lanes, much faster northbound returns. Ready Lane is for travelers with RFID-enabled documents (passport card, enhanced license) and is faster than the regular lane but slower than SENTRI.

Yes. Going south: any commercial goods, alcohol over personal limits, prescription medication in original packaging. Coming north: any food (most fresh produce is restricted), alcohol over duty-free, and any cash above $10,000.

Southbound is light-touch — most travelers wave through. The intensive check is northbound, where US Customs inspects your vehicle and documents. Plan extra time for the return.

For driving: passport (or passport card by land), valid driver's license, vehicle registration, and proof of Mexican auto insurance. For walking across: passport or passport card.

Most US carriers (T-Mobile, Verizon, AT&T) include Mexico in their main plans. Confirm before you travel. If your plan charges roaming, swap to a local SIM or eSIM at the airport — Telcel has the best coverage outside cities.

Tourist zones are bilingual; outside them, basic Spanish helps a lot. A translation app (downloaded for offline use) covers most situations. Locals are patient with attempts.

Hot, cooked-to-order food from busy stands is generally safer than salads or unrefrigerated items. Avoid raw vegetables you can't peel and unpasteurized dairy. If in doubt, eat where locals are eating.

Pesos. The exchange rate when paying with dollars is almost always worse than what you'd get at an ATM, and small businesses often round up.
