Are Kei Trucks Legal? Inside the State-by-State Battle Over America's Favorite Tiny Import

The tiny truck America can't quite agree on

The kei truck — Japan's pint-sized, right-hand-drive workhorse — has become the most argued-over import in America, and the argument is finally producing results. So, are kei trucks legal? It depends entirely on your ZIP code. As of June 2026, kei trucks can be registered for road use in 25 states, face limited or low-speed restrictions in 7, and are refused registration outright in 10, according to data compiled by World Population Review and Carmanji. The same Honda Acty that legally hauls firewood in one state can be denied a plate across the border.

That patchwork made 2026 the kei movement's most interesting year yet. Vermont — long a holdout — signed legalization into law in June, and enthusiasts elsewhere are treating it as a template. For anyone eyeing a Suzuki Carry or Daihatsu Hijet, the legal map has never shifted faster.

One caveat: this is reporting, not legal advice. Rules vary by state and change fast — verify with your own DMV before buying.

Where are kei trucks legal? The 25-7-10 map

Break the country into three buckets: 25 friendly states register kei trucks for ordinary road use, 7 cautious ones attach limited-use or low-speed strings, and 10 refusers will not issue a plate as of June 2026.

The holdout list, per Carmanji's June 2026 tally, includes New York, New Jersey, Georgia, Oregon, Nevada, Maryland, Iowa, New Mexico, and Alaska. That roster cuts across political and geographic lines — this is a bureaucratic fight, and it largely traces back to a single document.

Most bans lean on model guidance from AAMVA, the motor-vehicle administrators' association, which called kei vehicles substandard on safety and emissions. The detail fueling the legalization movement: it is guidance, not binding law. DMVs adopted it administratively — and what an agency adopted by memo, advocates argue, a legislature can undo by statute.

Vermont flips: anatomy of a legalization win

Vermont is the proof of concept. Governor Phil Scott signed S.326 on June 16, 2026, and from July 1, 2026 the state registers kei trucks as regular motor vehicles — no special speed restrictions, no low-speed asterisk, no back-roads-only compromise. A holdout state flipped to full legality in a single legislative session.

The significance is the playbook: move the fight from the DMV counter to the statehouse and force lawmakers to defend a ban most of them never enacted. Expect similar bills elsewhere — though passage is anyone's guess, and we would hedge hard on New York and New Jersey.

The loophole that built the boom

None of this works without the federal side. Kei trucks enter the country under the 25-year import exemption, which lets vehicles at least a quarter-century old bypass NHTSA safety and EPA emissions compliance entirely. The catch: the exemption gets the truck through the port, not onto the road — registration remains the states' turf. As our guide to importing an EV explains, clearing customs and getting a plate are two very different battles.

The honest assessment

The kei truck case is genuinely strong: cheap to run, absurdly practical, and beloved by the farmers and small businesses that actually use them. The bans rest on non-binding guidance rather than laws debated in any legislature, and Vermont just showed how quickly that foundation crumbles. But be honest about the other side: these are small, light vehicles built for Japanese roads — our rundown of the best kei cars in Japan shows the breed at home — and mixing one with American freeway traffic is a physics problem no statute fixes. Legal is not the same as ideal. Increasingly, legislatures are deciding adults can make that call, as they already do with motorcycles and vintage cars.

The questions buyers actually ask

Can I import a kei truck even if my state refuses to register it? Generally yes — import and registration are separate hurdles. The federal 25-year exemption governs entry; your state governs plates. You could legally own a truck you cannot legally drive, so check registration rules first.

Which states still refuse kei truck registration? As of June 2026, the refusal list includes New York, New Jersey, Georgia, Oregon, Nevada, Maryland, Iowa, New Mexico, and Alaska, per Carmanji. Another 7 states allow only limited or low-speed use.

Will more states legalize kei trucks? Momentum points that way — Vermont's S.326 took effect July 1, 2026, and it hands advocates a working template. But nothing is guaranteed. Treat any "repeal coming soon" chatter as expected, not confirmed.

Key takeaways

• As of June 2026, kei trucks are registrable in 25 states, restricted in 7, and refused in 10.
• Vermont's S.326, signed June 16, 2026, registers kei trucks as regular vehicles from July 1, 2026 — no speed restrictions.
• Holdouts refusing registration include New York, New Jersey, Georgia, Oregon, Nevada, Maryland, Iowa, New Mexico, and Alaska.
• Most bans trace to non-binding AAMVA model guidance, not laws passed by legislatures — the crux of the repeal movement.
• The federal 25-year exemption lets kei trucks bypass NHTSA/EPA compliance at import, but states control registration.
