Massachusetts Kei Trucks: Why H.4053 Could Lock In the 2024 Win

Massachusetts is the state that proved kei truck owners can actually win. In June 2024 the Registry of Motor Vehicles announced it would stop registering Japanese mini trucks and started clawing back plates from people who had done everything right. Three months later, after a loud and organized backlash, the RMV folded. Owners got their registrations back. It was the first clean victory in the state level fight over imported mini trucks, and it happened fast.

Here is the catch. That win lives in a policy advisory, not in the law books. The same office that reversed the ban could reverse the reversal whenever a new administrator decides kei trucks make them nervous. House Bill 4053, sitting in committee right now, is the fix for that. It would write kei vehicles into Massachusetts statute so no future RMV memo can quietly erase them again. If you own a Suzuki Carry in the Commonwealth, or you are thinking about importing one, this is the bill that decides whether your truck stays legal on a clerk's whim or on the actual law.

How Massachusetts Banned Kei Trucks, Then Backed Down

On June 18, 2024, the RMV told inspection stations and owners it would no longer register kei vehicles. The justification was a 2011 policy paper from the American Association of Motor Vehicle Administrators, the standards body whose guidance a lot of state DMVs lean on. The AAMVA argument was the usual one: these vehicles were not built to meet North American safety standards and do not meet current emissions rules, so they do not belong on public roads.

The problem is that the paper was aimed at a different animal. As Streetsblog Massachusetts laid out, the document that got weaponized against Honda Acty and Daihatsu Hijet owners was written about low speed off road utility vehicles, the kind capped at 25 mph and never meant for a public street. Genuine JDM kei trucks are a separate category, and the federal government has been fine with importing and driving them for decades as long as they clear the 25 year exemption from Federal Motor Vehicle Safety Standards. The RMV took guidance about golf cart adjacent farm vehicles and applied it to road legal Japanese pickups that had already been wearing Massachusetts plates for years.

Owners who had legally imported their trucks, paid the fees, and passed inspection became overnight outlaws. Some had spent five figures. The response was immediate and organized. A group operating as the Massachusetts JDM Imports Advocates rallied owners, and Representative Steven S. Howitt filed a bill to undo the ban outright. The pressure worked faster than anyone expected. As The Drive and other outlets reported, the RMV reversed itself, and announced in a September 2024 advisory that kei vehicles meeting the federal age rule would be registered after all, effective September 18, 2024. Roughly three months, start to finish. That is lightning speed for a government walking back a vehicle policy.

What the RMV Actually Allows Right Now

As of today the rule is simple: if your kei vehicle is 25 years or older, the RMV will title and register it. That tracks the federal NHTSA import exemption, which lets vehicles a quarter century old skip the safety standards that apply to new cars. Trucks already registered before the 2024 ban kept their registrations without a gap. Newly imported trucks need the full paper trail proving age and legal entry through customs.

The process looks like a normal vehicle registration with a couple of import specific steps. You need a title or the manufacturer's certificate of origin, a bill of sale, your federal customs paperwork, proof of Massachusetts residency, and an active insurance policy before you ever walk into a service center. You cannot register a freshly imported truck online, so plan on an in person visit and an RMV-1 form where you pick passenger or commercial plates based on how you will use the truck. The state of Massachusetts also still requires a safety inspection, and many imported trucks need lighting tweaks to pass, usually amber front signals, red rear signals, and DOT compliant bulbs. The RMV's own how to pages walk through the document checklist if you want the official version.

On cost, budget realistically. The title fee runs $75, two year passenger registration is about $60, Massachusetts sales tax is 6.25 percent of the purchase price, inspection is $35, and municipal excise tax varies by town and vehicle value. Most owners land somewhere in the $300 to $600 range for the first year once everything is stacked up. You also need to line up coverage first, which is its own small project for an imported truck, so read our kei truck insurance guide before you call an agent. One restriction never goes away no matter what the RMV does: interstate highways are off limits to kei trucks in every state, Massachusetts included, so the Mass Pike and I-95 are out. State routes, county roads, and local streets are where these trucks live.

Why H.4053 Matters More Than the Reversal Did

The 2024 reversal felt like the finish line. It was not. It was an administrative decision, and administrative decisions are exactly as durable as the next administrator's mood. The RMV even said at the time that it would keep studying the safety question and might conduct a formal review, which is bureaucrat for "we reserve the right to change our minds." That is the whole reason H.4053 exists.

Filed in January 2025 as "An Act to legalize Kei vehicles in the Commonwealth," the bill does something the advisory cannot: it puts kei vehicles into the actual general laws. It defines a kei vehicle by hard numbers, an engine of 660cc or smaller, a body 130 inches or less in length and 60 inches or less in width, and it directs the RMV to accept registration applications for vehicles that fit. Once that language is statute, a future RMV cannot kill kei registration with an internal memo. It would take the legislature to undo it, which is a far higher bar and a far more public fight.

The status, honestly, is the frustrating part. The bill was reported favorably out of committee and referred to the House Ways and Means Committee back in the summer of 2025. As of spring 2026 it is still parked there, reported favorably but never brought to a floor vote. Ways and Means is where a lot of well meaning bills go to sit quietly until a session ends. The reversal that owners won in three months has now spent well over a year waiting for the legislature to make it permanent, and the clock on the 194th General Court is real. If H.4053 does not move before the session closes, the whole thing resets and someone has to refile.

How Massachusetts Fits the New England Map

Massachusetts is not fighting this alone, and the regional picture is the best argument that codification is worth the trouble. Vermont went the legislative route and baked a kei truck definition into an omnibus motor vehicle bill that cleared the Senate on March 25, 2026, complete with a Mini Truck Day rally at the Statehouse. Maine took the slow, thorough path, running a formal study working group whose report fed into SP 884, a bill still grinding through committee. New Hampshire allows mini trucks but leashes them with a 35 mph cap and a 25 mile radius from home or business. Connecticut registers them through the DMV for street use. Rhode Island sits in the restricted middle.

Different states, different mechanisms, same lesson: the durable wins are the ones written into law, not handed down by a registry. The advocacy group SEMA Action Network has been hammering this point as it pushes bills state by state, because federal action is not coming to save anyone. Vehicle registration is a state decision, full stop. Massachusetts proved owners can win the administrative fight. H.4053 is about proving they can win the permanent one.

Buying and Registering a Kei Truck in Massachusetts Today

If you want a truck right now, the good news is that today's RMV policy is friendly and the 25 year window keeps getting better. Every month another batch of late 1990s and 2001 trucks crosses into eligibility, which means cleaner, fuel injected examples with working four wheel drive instead of the carbureted relics that dominated imports a decade ago. You can buy through a domestic importer that handles the customs and compliance side, or go direct from a Japanese auction and manage the import process yourself. Established stateside sellers like Duncan Imports hand you a truck that already cleared customs with paperwork in order, which is the path of least resistance for a first Massachusetts registration.

Whichever route you pick, the registration math rewards homework. Confirm the build date puts the truck over 25 years before you wire any money, because a truck that is even a few months short is a paperweight until it ages in. Get the customs documents in hand, not promised. Line up insurance before the service center visit, and expect to do a lighting pass for inspection. The owners in r/keitruck who have already run the Massachusetts gauntlet are a genuinely useful resource for which inspection stations are smooth and which RMV branches still trip over the import paperwork. Walking in with a model that has the deepest registration history in the state, the Carry, also tends to mean the fewest raised eyebrows at the counter.

The Bottom Line

Massachusetts already did the hard part. Owners organized, the RMV reversed a bad ban in three months, and kei trucks are fully registrable today under the federal 25 year rule. But that win is sitting on an administrative ledge, and H.4053 is the bill that would move it onto solid statutory ground. Until it passes, the legal status that owners fought for can be unwound by the same kind of memo that started the mess in 2024. If you own a kei truck in the Commonwealth, the move is simple: register now while the door is open, and call your state rep about H.4053 by bill number so the legislature finishes the job. A win you have to win twice is not really a win yet.
