Indiana is one of the most usable states in the country for a kei truck, and it is worth saying why precisely: a registered mini-truck may be driven on every public road in Indiana except an interstate. No posted-speed ceiling, no township opt-in, no farm-only limit, no antique restriction.
Indiana also wrote its definition better than most states did — it has no length limit, so the 130-inch problem that affects Pennsylvania and North Carolina does not exist here. It has a different constraint instead, and it is the one thing to check before you buy: an unladen dry weight cap of 1,600 pounds, which sits right in the middle of what these trucks actually weigh.
I research Japan’s used vehicle market from Sapporo, and the weight figures below come from the manufacturers’ own specification sheets.
The Short Answer
- Roads: all of them except interstates. IC 9-21-8-46 prohibits mini-truck operation on interstate highways. Everything else is open.
- Registration: required, with its own mini-truck plate. First-time Indiana titling goes by mail to the BMV, not over the counter.
- Engine displacement is a floor, not a ceiling — “not less than 660 cubic centimeters.” A kei truck has exactly 660.
- No length limit. Indiana avoided the trap several other states fell into.
- Weight is the real gate: 1,600 lb unladen dry. Some kei trucks are comfortably inside; the Honda Acty HA6/HA7 is not.
- A locking enclosed cab and a heated interior are required — which every kei truck has, and no UTV does.
What the Statute Says
IC 9-13-2-103.1 defines a mini-truck as a truck that:
(1) is powered by an internal combustion engine with a piston or rotary displacement of not less than six hundred sixty (660) cubic centimeters; (2) is sixty (60) inches or less in width; (3) has an unladen dry weight of one thousand six hundred (1,600) pounds or less; (4) can achieve a top speed of not more than sixty (60) miles per hour; (5) is manufactured with a locking enclosed cab and a heated interior; and (6) is operated on a highway.
Read that as a piece of drafting and it is unusually thoughtful. Three clauses are doing deliberate work:
The engine floor. Most states cap displacement at 660cc, which is Japan’s kei ceiling. Indiana requires at least 660cc. That inverts the purpose: instead of keeping kei trucks in, the figure keeps golf carts, side-by-sides and small utility vehicles out. A kei truck sits exactly on the line and qualifies.
The cab and heater clause. “Manufactured with a locking enclosed cab and a heated interior” is the same idea by another route. A side-by-side has neither as standard; every kei truck has both, because Japan is cold in winter and vehicles get locked. It is a functional test that separates a small truck from a recreational machine without measuring anything.
No length limit at all. Which matters more than it sounds. Pennsylvania, North Carolina and Massachusetts’ pending bill all define these vehicles at 130 inches or less — the Japanese standard replaced in October 1998 — while every kei truck built from 1999 measures 133.7 inches. Indiana simply did not write that number down, so the problem cannot arise here. The comparison of state definitions sets out all three templates.
The 1,600-Pound Question
Here is what to check before you bid, because Indiana’s weight cap is not a comfortable margin in either direction.
1,600 pounds is 725.7 kg. Japanese manufacturers publish 車両重量 — kerb weight, including coolant, oil and a full fuel tank. Here are the two makers who still publish 1990s figures themselves:
| Model | Published kerb weight | In pounds | Against Indiana’s 1,600 lb cap |
|---|---|---|---|
| Suzuki Carry (Jan 1999), lightest published variant | 670 kg | 1,477 lb | Inside |
| Suzuki Carry (Jan 1999), heaviest published variant | 740 kg | 1,631 lb | Over on kerb weight |
| Honda Acty HA6/HA7 (1999–2009) | 800–850 kg | 1,764–1,874 lb | Well over |
Suzuki publishes seven variants of the January 1999 Carry, spanning 670 to 740 kg — the type codes are GD-DA52T for 2WD and GD-DB52T for 4WD, and as on any truck the four-wheel-drive and automatic versions sit at the heavy end of that range. Figures from Suzuki’s own digital spec library; Acty figures from Honda’s own model archive. Daihatsu, Subaru and Mitsubishi no longer publish specifications for these generations, so I am not going to quote figures for them here.
Kerb weight is not dry weight — and it cuts in your favour
Indiana’s term is “unladen dry weight,” which conventionally excludes fluids. The Japanese figure includes them, so it is the higher of the two measures. A kei truck’s fuel tank holds roughly 35–40 litres, which is about 26–30 kg of petrol, plus perhaps 8–10 kg of coolant and oil. Call it 35–40 kg of difference, as an estimate rather than a measurement.
Run that through and the picture becomes:
- The Carry clears comfortably. Even the heaviest 740 kg variant drops to roughly 700–705 kg on a dry figure, which is about 1,545–1,555 lb — inside 1,600.
- The Acty still does not. An 800 kg Acty estimates to roughly 760–765 kg dry, or about 1,675–1,687 lb. The 850 kg variants are further out. There is no plausible fluid deduction that brings an HA6/HA7 Acty under 1,600 pounds.
So the practical rule for an Indiana buyer: the Acty is the one model to be careful about. If you want a Honda, the earlier HA3/HA4 generation is the shorter of the two and very likely the lighter — but Honda no longer publishes weight figures for it, so treat that as something to verify rather than assume. Otherwise the Carry, and by extension the other cab-over trucks in its weight class, are not where the problem is.
What I cannot do is tell you what number the BMV will use for a specific truck, because “unladen dry weight” for an imported vehicle is not printed on any document you will receive from Japan. If you are looking at a heavier variant, that is a question to put to the BMV before money moves — and the arithmetic above is what to put in the email.
Registering One
Indiana’s process has one wrinkle worth planning around. Per the BMV’s mini-truck page, first-time Indiana titling is not a branch transaction: “a title application packet must be completed and mailed to the BMV for processing.” The BMV publishes a Mini-Truck Title Application Packet listing what to include.
That means the timeline is postal rather than same-day, and it means the paperwork has to be right the first time. Your import documents — the Japanese export certificate and its translation, the Customs entry summary, the DOT and EPA declarations — are the pieces to have organised before the truck lands. The import guide covers what each of those is and when it arrives.
Once titled, a mini-truck gets its own plate designation. Annual costs are the ordinary Indiana set: registration fee, vehicle excise tax, any county or municipal excise tax where you register, and the Transportation Infrastructure Improvement Fee.
Where You Can Actually Drive It
IC 9-21-8-46 is the operative restriction, and it is a single prohibition: a mini-truck may not be operated on an interstate highway. Nothing else in the statutory scheme caps you by posted speed or road class.
Compare that with the states either side of Indiana in permissiveness. North Carolina allows only roads posted at 55 mph and under. Florida caps you at 35. Ohio and Kentucky require a local ordinance to opt in at all. Nebraska is the closest state to Indiana in approach — all roads except interstates, expressways and freeways — and its definition is the better written of the two. Indiana gives you US highways, state routes, county roads and city streets without a speed test — which for a truck that cruises at 50–55 is effectively the whole usable network.
The interstate exclusion is not much of a loss in practice. The honest performance numbers are in the specs guide, and a 660cc truck on a 70 mph interstate is not somewhere you want to be regardless of what the law permits.
For Reference: What These Trucks Cost
Indiana is an open state, so the purchase is the decision. This is the Japan-side market, measured August 19, 2026 — every eligible truck listed publicly in Japan, at ¥159/USD:
| Model | Listings in Japan | Median price in Japan |
|---|---|---|
| Subaru Sambar | 78 | ¥364,000 (≈$2,289) |
| Mitsubishi Minicab | 64 | ¥394,000 (≈$2,478) |
| Honda Acty | 80 | ¥398,000 (≈$2,503) |
| Suzuki Carry | 99 | ¥399,000 (≈$2,509) |
| Daihatsu Hijet | 60 | ¥453,000 (≈$2,849) |
Landed cost runs about $4,800–6,700 depending on specification, itemised in the cost guide, with the raw dataset published so you can recount any figure.
Two Indiana notes. Indiana salts its roads, so the underbody advice that applies in Michigan applies here too: pay the premium for a truck from a warm, dry Japanese prefecture, read the auction sheet for C codes rather than paint grade, and undercoat it in the first month. And since the weight cap makes the Acty awkward here, the Carry and Sambar guides are the ones worth reading first.
Indiana gives you every road but the interstate, which makes this one of the better states to actually use one of these trucks. Two things to settle before you bid: that the build month clears 25 years, and that the variant you are looking at is not on the wrong side of 1,600 pounds.

FAQ
Are kei trucks street legal in Indiana?
Yes. A mini-truck that meets the definition in IC 9-13-2-103.1 must be titled and registered, and may then be driven on every public road in Indiana except an interstate highway. There is no posted-speed restriction and no local opt-in requirement.
Can I drive a kei truck on the interstate in Indiana?
No. IC 9-21-8-46 prohibits operating a mini-truck on any part of an interstate highway. Every other road class is available.
Does Indiana have a length limit for kei trucks?
No, and that is worth knowing because several states do. Pennsylvania, North Carolina and Massachusetts’ pending bill define these vehicles at 130 inches or less, which excludes every kei truck built from 1999. Indiana’s definition has no length figure at all.
Will my kei truck pass Indiana’s 1,600 lb weight limit?
A Suzuki Carry will, including its heaviest published variant, once you account for the difference between Japanese kerb weight and Indiana’s “unladen dry weight.” A Honda Acty HA6/HA7 at 800–850 kg will not — no plausible fluid deduction brings it under. If you want a Honda for Indiana, look at the earlier HA3/HA4 generation and confirm its weight, which Honda no longer publishes.
Why does Indiana require an engine of at least 660cc?
Because a floor excludes golf carts and side-by-sides from the class rather than excluding kei trucks from it. The same logic sits behind the requirement for a locking enclosed cab and a heated interior — both standard on a kei truck, neither standard on a UTV.
How do I register a kei truck in Indiana?
First-time titling is done by mail: the BMV requires a completed Mini-Truck Title Application Packet sent to it for processing rather than handled at a branch. Plan the timeline accordingly and have your import paperwork organised before the truck arrives.
