Legality guide
Is a kei truck legal in your state?
Import legal does not mean street legal. Federal law and state law answer two different questions, and mixing them up is the most common mistake first-time buyers make.
Two separate rules
The federal 25-year rule decides whether a kei truck can enter the country at all. Once a vehicle turns 25 years old, it is exempt from Federal Motor Vehicle Safety Standards (FMVSS) and can be imported without meeting US crash and emissions testing. A new kei truck cannot be imported for road use under any circumstance -- only for off-road or private-property use.
Clearing that federal hurdle says nothing about whether your state will then register the truck for public roads. That decision sits entirely with each state’s DMV, and it varies enormously -- from full registration with no special rules, to speed and road-class limits, to an outright refusal to title the vehicle at all.
The three tiers
Standard road registration for 25+ year kei trucks, generally no kei-specific restrictions beyond normal traffic law.
Registration is possible but comes with conditions: speed caps, road-class limits, or local approval requirements.
No path to public road registration. Off-road, farm, and private-property use only.
Road legal
Texas
Road legalSB 1816 (2023) legalized 25+ year kei trucks statewide, including limited interstate use -- Texas is the clearest exception to the usual interstate ban.
Washington
Road legal25+ year kei trucks can be registered for public road use under standard DMV procedures.
Massachusetts
Road legalBriefly paused new registrations in 2024, then reversed course and resumed full registration for 25+ year kei vehicles.
Restricted
Florida

Off-road only
California
Off-road onlyNo public road registration regardless of age. Off-road, farm, and private-property use only.
New York
Off-road onlyDMV will not title a kei truck unless it meets full FMVSS/EPA standards, which effectively excludes almost all imports.
New Jersey
Off-road onlySame FMVSS/EPA compliance bar as New York -- road registration is not available in practice.
Iowa
Off-road onlyState code allows the DMV to refuse registration to vehicles without a federal safety-standard label. Off-road and farm use remain legal.
Pennsylvania
Off-road onlyStopped issuing standard registrations for kei trucks in 2021 -- now off-road, farm, or antique-vehicle status only.
Rhode Island
Off-road onlyBegan revoking existing kei truck registrations in 2021 and does not accept new ones.
Before you buy
- Call your state DMV directly and ask about kei truck or mini-truck registration specifically -- generic vehicle-import advice often misses kei-specific rules.
- Check the title type before you buy. An off-road-only or farm-use title usually cannot be converted to a road title later.
- Watch for speed-limited models. A truck factory-limited to 25 mph cannot be road-registered in any state.
- Ask about county or local rules even in permissive states -- some vary by jurisdiction.
