Rules for overlanding in Mexico

Our summary of the country advice published by the Italian Ministry of Foreign Affairs (Viaggiare Sicuri) on 26 May 2026.

Which licence you need

All vehicles — A national licence covers you if you drive your own vehicle, and an International Driving Permit (1949 Geneva or 1968 Vienna model) is recommended if you rent one. Check what applies to the licence you hold.

An International Driving Permit states the categories it covers: check yours covers what you will actually drive. A car licence does not cover a motorcycle, and a heavy camper or a truck can need a higher category.

At the wheel

Insurance — Foreign policies are not valid in Mexico. Short-term cover for a day or a week costs roughly 10 to 20 USD a day and can be bought either before you arrive or at the border.
Temporary import — No customs document is required to bring a vehicle in temporarily to Baja California or within the 25-mile strip along the United States border. The tax authority, SAT, is the office to ask about anything beyond that.
Never drive at night — The basic precaution for anyone travelling by car is to stick to the main highways rather than secondary roads and never to travel in the evening or at night. Air travel is recommended between Mexican cities; if you drive from one to another, keep strictly to daylight hours.
Breakdown assistance — If your vehicle breaks down on a highway, call the Angeles Verdes on 078. They help with small repairs, fuel supplies and short-distance towing.
Alcohol — The limit is 0.08%, dropping to 0.05% for drivers of light goods vehicles and 0.00% for commercial passenger transport. Police can stop any driver they suspect, and over the limit means a fine, 12 to 36 hours held in a dedicated centre and a 15-day licence suspension. Checks are frequent, including inside cities and especially at night near bars and clubs; stay calm and cooperative with the officers.
Rules of the road — Traffic drives on the right and overtakes on the left, and overtaking is not allowed where visibility is insufficient, such as approaching a bend, or within 30 m of a junction or a level crossing. Between 23:00 and 05:00 drivers may go through a red light at a signalled junction once they have checked the road is clear. Improper use of the horn is restricted or prohibited in Mexico City except where safety requires it, and allowed elsewhere in the country when needed.
Equipment on board — In Mexico City seatbelts are compulsory on every seat, children may not be carried in the front seats, and helmets are compulsory for mopeds, motorcycles and motorised tricycles. Every two- and three-wheeled motor vehicle must run with lights on 24 hours a day, and all vehicles must switch them on in poor visibility. A warning triangle goes at least 20 m behind the vehicle in town and at least 100 m in the country.
Cancún to Tulum — The coast road between Cancún and Tulum is often the scene of accidents, caused by reckless driving, by trucks and earth-movers on the road and by poor lighting at night. Money and documents are frequently stolen in Cancún, Playa del Carmen and Tulum, so keep excursions away from your accommodation to a minimum and use only taxi firms based at the airport.

What catches travellers out

Documents at the border — Immigration officers can require a document proving your accommodation with the address and length of stay, a ticket out of the country, proof of enough money for the stay, evidence of where you normally live, your tour or activity bookings and, if you are staying with someone, an invitation letter with the host's details, which they may telephone to check. Without that paperwork entry is refused, and the rules have been applied strictly.
Check your permitted days — No visa is needed for tourism or business for up to 180 days, but the border officer decides how many days you actually get and writes them on the slip issued at passport control. Check that number carefully and ask for enough days to cover your whole stay, because the permit must not expire before you leave.
Customs and e-cigarettes — Bringing electronic cigarettes and their refill liquids into Mexico is prohibited. You may import goods worth up to 300 USD per person by land, or 500 USD by air or sea, with a 16% tax on the excess value. There is no restriction on cash up to 10,000 USD; above that you must declare it on the currency form at entry.
Drugs — Mexican law is very severe on trafficking and possession, and personal use is prohibited, with even soft drugs or hallucinogenic mushrooms treated as a criminal offence. Almost every Italian held in a Mexican prison is there for this, and those prisons remain extremely violent.
