You can legally drive a car with foreign plates in the US for up to one year, as long as you are a nonresident, the vehicle is for your personal use, and you export it before that year is up.1U.S. Customs and Border Protection. Importing a Motor Vehicle After that, or once you settle in a state, the rules change completely: the car has to clear federal safety and emissions standards before any state will register it.
How Long the One-Year Rule Lasts
U.S. Customs and Border Protection lets nonresidents bring a personal vehicle into the country duty-free for up to one year. The clock starts the day the vehicle enters the U.S., and there is no extension or renewal.2U.S. Customs and Border Protection. Returning to the United States With a Vehicle and Household Goods During that window the car does not have to meet U.S. safety or emissions rules, but it cannot be sold here, and it has to leave before the year runs out.
Two conditions keep the exemption alive. The vehicle has to arrive around the same time as its owner, and it has to be used only for personal transportation and tourism. Commercial use, including rideshare driving and freight, breaks the exemption. If CBP finds that the car was sold or is working commercially, the temporary status is void and the vehicle is subject to forfeiture.1U.S. Customs and Border Protection. Importing a Motor Vehicle
Who Can Use Their Own Plates and License
Drivers from Canada and Mexico are the most common foreign-plated cars on U.S. roads. Both countries have arrangements with the United States that let motorists tour the U.S. on their own national plates and licenses, without needing U.S. plates or a U.S.-issued permit.1U.S. Customs and Border Protection. Importing a Motor Vehicle The one-year cap and the personal-use rule still apply.
Visitors from countries that ratified the 1949 Convention on International Road Traffic get similar treatment. That covers most of Europe, much of South America, Australia, Japan, India, and many other nations. If your country signed the convention, you can drive here for up to a year on your home plates and license.1U.S. Customs and Border Protection. Importing a Motor Vehicle
What to Carry With You
Keep your home-country driver’s license and the vehicle’s foreign registration on you whenever you’re driving. If the license is not in English, get an International Driving Permit before you leave home. Some states require the IDP and some do not, and the rules are not uniform, so treat it as effectively necessary.3USAGov. Driving in the U.S. if You Are Not a Citizen An IDP is a standardized translation of your license, valid for one year, and it can only be issued in your home country.
Hold onto any CBP paperwork you received at the port of entry, along with your passport and visa. A traffic stop or a border checkpoint is easier when the whole file is in one place.
Insurance Is Where Visitors Get Caught
Most foreign auto policies do not provide third-party liability coverage inside the United States. If you cause a crash, your home insurer will not pay the other driver’s medical bills or property damage. Every state requires liability insurance. You can be ticketed, have the car impounded, and be sued personally with nothing behind you.
Canadian policies are the main exception. Most extend into the U.S., so Canadian visitors driving their own cars are usually already covered. Confirm with your insurer before you cross.
Mexican auto insurance does not cover U.S. third-party liability. Drivers from Mexico need a separate short-term U.S. liability policy, sold by specialty insurers that write on foreign-plated cars. Visitors from anywhere else should line up a U.S.-based policy before driving. Not every mainstream carrier will write one, but specialty insurers do.
When Visitor Status Ends
The one-year privilege is only for nonresidents. The moment you establish residency in a state, the exemption ends, even if months remain on the CBP clock. Residency triggers vary by state but commonly include taking a job, enrolling children in school, registering to vote, or signing a long-term lease.
Once you’re a resident, you have to register the car with the state motor vehicle agency. Deadlines range widely. Some states expect registration immediately with no grace period; others give up to 90 days; a large group sets the window at 30 days. Driving on foreign plates past your state’s deadline is treated the same as driving an unregistered car: fines, and in many places, impoundment.
Permanently Importing the Vehicle
No state will register a foreign vehicle until it has been permanently imported under federal law. Two agencies control that gate. The National Highway Traffic Safety Administration sets the safety standards, and the Environmental Protection Agency sets the emissions standards. Both have to be satisfied before CBP clears the car.4U.S. Environmental Protection Agency (EPA). Learn About Importing Vehicles and Engines
If the car was originally built for the U.S. market, it carries manufacturer labels certifying compliance with Federal Motor Vehicle Safety Standards and EPA emissions rules. Importing one is relatively simple. The owner files DOT Form HS-7 and EPA Form 3520-1 with CBP at the port of entry, and once cleared, moves on to state registration.5U.S. Customs and Border Protection. Vehicle – How Can I Obtain EPA Form 3520-1 and DOT Form HS-7
A car built for a foreign market is another matter. It was designed to meet the standards of the country where it was sold, not U.S. standards. To bring it in permanently, you hire a Registered Importer approved by NHTSA to modify the vehicle for safety compliance.6National Highway Traffic Safety Administration. Importing a Vehicle – Importation and Certification FAQs On emissions, a separate Independent Commercial Importer certified by the EPA handles the modifications, testing, and certification.4U.S. Environmental Protection Agency (EPA). Learn About Importing Vehicles and Engines Costs for modifications, testing, and certification run from several thousand dollars into five figures, depending on how far the car deviates from U.S. requirements.
Duties, Tariffs, and the Gas Guzzler Tax
Temporary visitors bringing a car in for personal use under the one-year rule pay no duty. Permanent imports are taxed. As of April 2025, a 25 percent tariff under Section 232 applies to imported automobiles, including passenger cars, SUVs, and light trucks, on top of any other applicable duties.7Federal Register. Adjusting Imports of Automobiles and Automobile Parts Into the United States
Cars from countries with trade agreements may face lower combined rates. As of early 2026, vehicles from the European Union, Japan, and South Korea are subject to a combined rate of 15 percent under negotiated frameworks, and certain vehicles from the United Kingdom face rates between 7.5 and 10 percent under a separate deal. Vehicles qualifying under USMCA with Canada and Mexico may be exempt.8U.S. Customs and Border Protection (CBP). U.S. Tariff Overview January 2026 These rates have shifted more than once, so checking the current number with a licensed customs broker before shipping is worth the fee.
The federal Gas Guzzler Tax hits cars with poor fuel economy. Any automobile rated below 22.5 miles per gallon triggers it, scaling from $1,000 just under 22.5 MPG to $7,700 for vehicles rated below 12.5 MPG. For imports, the importer counts as the manufacturer, so the tax is charged at entry.9Office of the Law Revision Counsel. 26 USC 4064 Gas Guzzler Tax
The 25-Year and 21-Year Exemptions
A vehicle that is at least 25 years old, measured from its month and year of manufacture, is exempt from Federal Motor Vehicle Safety Standards. It can be permanently imported without a Registered Importer and without safety modifications.10eCFR. 49 CFR Part 591 – Importation of Vehicles and Equipment This is why late-1990s and early-2000s Japanese domestic-market cars have started appearing at U.S. dealerships and car shows. In 2026, cars manufactured in 2001 or earlier qualify.
Emissions has a slightly shorter timeline. Vehicles more than 20 years old, effectively 21 or older when you subtract the production year from the import year, are exempt from EPA emissions requirements. There is a catch: the car still has to be imported through an Independent Commercial Importer, even though no actual modifications are needed.11eCFR. 19 CFR 12.73 – Importation of Motor Vehicles and Motor Vehicle Equipment Subject to Federal Motor Vehicle Safety, Bumper and Theft Prevention Standards Most people importing a 25-year-old car will clear both thresholds at once. A car aged 21 to 24 clears emissions but still has to go through the full NHTSA safety process.
What Happens If You Break the Rules
Federal enforcement here has teeth. If a nonresident fails to export a temporarily imported car before the one-year deadline, the vehicle is subject to forfeiture.1U.S. Customs and Border Protection. Importing a Motor Vehicle CBP can seize any vehicle that shows up at a port of entry without proper documentation, without a Registered Importer arrangement, or without a valid exemption.4U.S. Environmental Protection Agency (EPA). Learn About Importing Vehicles and Engines The importer is also on the hook for unpaid duties, taxes, fees, and liquidated damages under the entry bond.12eCFR. 19 CFR Part 10 Subpart A – Temporary Importations Under Bond
At the state level, driving an unregistered car past your new-resident deadline is a traffic violation in every state. Penalties usually include fines, and in some states police can impound the car at the roadside. Driving without valid U.S. insurance on top of that is a separate offense with its own fines and license consequences.
The most expensive mistake is shipping a non-conforming car to a U.S. port without first lining up a Registered Importer or confirming an exemption. If it doesn’t meet standards and no importer is in place, CBP can refuse entry and require the car to be exported at the owner’s cost. Shipping a car across an ocean twice is a hard way to learn to read the rules first.
