What documents do I need to drive from the US to Canada or Mexico by land?
Driving into Canada or Mexico you need a WHTI-compliant document such as a passport, passport card, enhanced licence or NEXUS card, plus vehicle papers and insurance.

Crossing by land - what you need
The Western Hemisphere Travel Initiative sets the rules, and it lists more accepted documents at a land border than at an airport. Booking your hotel on trip1 before you set off also gives you an address and a confirmation to show if an officer asks where you are staying.
- A US passport book. The one document that works for every country and every mode of travel.
- A US passport card. Wallet-sized and cheaper, valid for land and sea crossings from Canada, Mexico, the Caribbean and Bermuda only.
- An enhanced driver's licence or enhanced ID, available in Michigan, Minnesota, New York, Vermont and Washington.
- A trusted traveler card: NEXUS for Canada, SENTRI for Mexico, or Global Entry and FAST. These also get you into the dedicated lanes, which is the real reason people bother.
- For US citizen children under 16, an original or copy of a birth certificate or a Consular Report of Birth Abroad is accepted at land and sea crossings.
Why land rules differ from air rules
A land crossing accepts the cheaper documents, an airport generally does not. Fly back into the United States and you are expected to produce a passport book, so a passport card or enhanced licence leaves you stuck.
This catches people who drive down to Baja or across to Vancouver and then change plans, or who take a one-way rental and fly home. Also note that a standard driver's licence, REAL ID or not, proves identity but not citizenship, so it is not a crossing document on its own.
Driving into Canada
US citizens need no visa and no eTA to enter Canada by land, just proof of citizenship and identity. US permanent residents show their green card at the booth and do not need a passport when arriving directly from the United States.
For the car, bring the registration and proof of insurance. Most US policies extend into Canada, and your insurer can issue a Canadian non-resident inter-province motor vehicle liability insurance card as evidence, which is worth requesting before you leave.
Declare food, alcohol, tobacco and gifts honestly. Cannabis cannot cross the border in either direction even where it is legal on both sides, and an old drink-driving conviction can make you inadmissible, so check your situation before you drive rather than at the booth.
Driving into Mexico
A passport book or passport card gets you across, but the paperwork does not stop there. Mexican crossings are easy to drive straight through, so pull over at the immigration and customs building rather than assuming nobody wants to see you.
The tourist permit
Mexico's tourist permit, still widely called the FMM, is issued by the immigration authority INM at the crossing. Travellers staying within about 20 km of the border for 6 days or less are exempt. Everyone else needs one, applied for online or at an INM office; stays longer than seven days carry a fee, and a permit can run up to 180 days.
Get it stamped. An unstamped form counts for nothing if you are stopped inland or questioned on the way out. Exemptions for very short trips in the border area have tightened and differ by state, so ask at the INM window instead of relying on what worked years ago.
The vehicle import permit
Taking a US-plated car beyond the free zones means a temporary import permit from Banjercito, the army bank that issues them. The free zones are the Baja California peninsula, Quintana Roo, the Sonora free zone and the strip roughly 20 to 25 km from the border.
Apply online in advance or at the crossing, with your passport, tourist permit, driving licence and the original title or registration in your name. There is a permit fee plus a refundable deposit, and you must cancel the permit at the border on your way out or you lose the deposit and the right to get another one.
Mexican insurance
Important: Your US auto policy is generally not valid in Mexico. Mexican law requires liability cover from a Mexican licensed insurer, and after an accident without it your vehicle can be impounded and you can be held while liability is sorted out. Buy a short-term policy online before you travel or at an agency near the crossing.
Taking a rental car across
Read the rental agreement before you plan the route. Canada is usually permitted if you tell the counter in advance and collect the non-resident insurance card with the keys.
Mexico is much tighter. Many companies ban it, and those that allow it usually restrict pickup to branches in California, Arizona, New Mexico or Texas, require Mexican insurance bought at the counter, and insist the car returns to the United States. A rental also cannot normally get a vehicle import permit, because the title is not in your name, which keeps you inside the free zones.
Hotel check-in on the other side
Hotels in Canada and Mexico ask for government photo ID from the guest named on the booking, and Mexican hotels usually want to see the passport of a foreign guest. Bring the same document you crossed on, plus your trip1 confirmation so the desk can find the reservation.
A hotel may also ask for a card at check-in to hold a deposit for incidentals. That is the property's own policy and has nothing to do with how you paid for the room.
Driving from the US to Canada or Mexico - FAQ
US citizens need proof of identity and citizenship, and Canada recommends a valid passport. To drive back into the US you need a WHTI document: a passport book, passport card, enhanced driver's license, or a NEXUS, SENTRI or FAST card. US citizens need no visa or eTA for a tourist visit. Bring the car's registration and proof of insurance.
Only if it is an enhanced driver's license, which proves both identity and US citizenship. A standard license, including a REAL ID, proves who you are but not your citizenship, so it is not enough to return to the US. Enhanced licenses are issued by Michigan, Minnesota, New York, Vermont and Washington.
Canada may accept that combination from a US citizen arriving by land, since together they show your name, date of birth and citizenship. Getting back into the US is the problem: adults need a WHTI document such as a passport card or enhanced license. US citizen children under 16 can cross by land with just a birth certificate.
A valid US driver's license is accepted for visitors, although each province sets how long a foreign license can be used. Carry the vehicle registration and proof of insurance. Most US policies extend into Canada, and your insurer can issue a Canadian non-resident inter-province motor vehicle liability insurance card, which is worth requesting before you leave.
Cannabis cannot cross the border in either direction, even if bought legally. You must declare all food, plants and animal products, some of which are refused, and declare any firearms or weapons. Firewood needs a permit, and soil-covered vehicles can be refused. Cash of CAN$10,000 or more must be reported. Check the Canada Border Services Agency site before you go.
Yes. Mexican car insurance is required for all vehicles, and your US policy is generally not valid there. Without it, drivers involved in an accident, even a minor one, can be arrested regardless of who was at fault. Buy a short-term policy from a Mexican licensed insurer online before you travel or at an agency near the crossing.
