Tennessee is one of the few states whose statute says the word “mini-truck” and means yours. It is also the state with the most interesting decision attached, because there are two registration routes and they trade opposite freedoms.
- Medium speed vehicle: any street posted at 40 mph or less — but you must certify, under penalty of perjury, that the truck’s top speed is not more than 35 mph. In practice that means limiting the vehicle.
- Class I off-highway vehicle: keep the truck’s full speed — but you are confined to county roads, and the class calls for nonhighway tyres.
Tennessee is usually reported as “35 mph,” which reads as a road restriction. Read the state’s own form and it is also a restriction on the vehicle itself — something you certify under oath about the truck, not a speed you promise to drive. That distinction is the thing to settle before you buy rather than after.

The Short Answer
- Tennessee titles and registers these trucks. The statute names mini-trucks explicitly, and it covers gasoline vehicles rather than electric only.
- Route 1, medium speed vehicle: streets posted 40 mph or less; the truck’s top speed must be over 30 and not more than 35 mph.
- Route 2, Class I off-highway vehicle: top speed over 35 mph permitted; operation limited to county roads.
- Both routes require insurance under Tennessee’s financial responsibility law: 25/50/15.
- The equipment checklist is published and is a genuine pre-purchase list — details below.
- Two items to check on a specific truck: the windshield glazing marking and the VIN format.
- A Class D driver licence must be in your possession when operating a medium speed vehicle.
- Counties and TDOT may ban medium speed vehicles on any road they control, whatever it is posted at.
- No emissions testing anywhere in Tennessee since 2022 — guides that still list middle Tennessee counties are out of date.
Route 1: Medium Speed Vehicle
TCA § 55-1-125 defines the class:
“Medium speed vehicle” means any four-wheeled electric or gasoline-powered vehicle, excluding golf carts, whose top speed is greater than thirty miles per hour (30 mph), but whose maximum speed allowed is thirty-five miles per hour (35 mph) only on streets with a forty mile per hour (40 mph) or less posted speed limit… including neighborhood electric vehicles and mini-trucks.
Two things are unusual and both are in your favour. It says “electric or gasoline-powered” — compare Washington, where every low-speed class is electric-only and a petrol kei truck cannot enter at all. And it names mini-trucks in the definition, so there is no argument to have about whether your vehicle is the kind of thing the legislature meant.
The affidavit, and what you are actually certifying
Registration runs through the Department of Revenue’s Medium Speed Vehicle Affidavit, and this is where Tennessee does something clever that most states did not.
Other states require the manufacturer to certify compliance with FMVSS 571.500 — which is why the route fails in Virginia, since no Japanese maker will certify a kei truck against an American low-speed vehicle standard. Tennessee replaced that with an equipment checklist the applicant certifies. The affidavit lists the items required under 49 C.F.R. 571:
- Headlamps, stop lamps, front and rear turn signal lamps, tail lamps
- Reflex reflectors — one red on each side near the rear, and one on the rear
- Parking brake
- One exterior mirror on the driver’s side plus one more, either passenger side or interior
- A windshield conforming to the federal glazing standard, 49 C.F.R. 571.205
- Seat belts, Type 1 or 2, at each seating position
- A VIN conforming to 49 C.F.R. 565
And then the certification itself, which is the part to read twice:
Under penalties of perjury, I hereby certify that the vehicle… is equipped with the above listed items and meets all safety standards as required by the National Highway Traffic Safety Administration, 49 CFR 571, and the vehicle’s top speed is greater than thirty miles per hour (30 mph) but not more than thirty-five miles per hour (35 mph).
A kei truck is ordinarily capable of well over 35 mph — roughly 50 to 60 mph depending on model, gearing and drivetrain, which is why the point matters. To sign that affidavit honestly, the truck must actually be limited to 35 mph — a governor, a gearing change, or whatever your mechanic proposes. This is a modification you are certifying under oath, not a road rule you are agreeing to obey. If a seller or a guide tells you Tennessee is “35 mph roads” and leaves it there, they have missed the point of the document.
The driver requirement people miss
Printed at the foot of the same affidavit, under “Important Information,” is a line that has nothing to do with the truck: “Operators of medium speed vehicles must have a Class D driver license in their possession when operation these vehicles on Tennessee’s roads.” The typo is the state’s, and the form has carried it since revision 9-2008.
A Class D licence is Tennessee’s ordinary passenger-vehicle licence, so for most readers this changes nothing. It matters in two situations: a family member without a full licence who was going to use the truck around the property and occasionally on the street, and a farm operation where the driving is done by someone whose licence status you have not checked. A medium speed vehicle is not treated as a golf cart or a farm implement here.
The two items to check before you bid
The windshield. The affidavit requires glazing conforming to 49 C.F.R. 571.205. Japanese-market glass is marked to Japanese standards, and whether a county clerk looks for a DOT marking is a practical question worth asking in advance. Replacement glass is available but it is not a $50 job.
The VIN. The affidavit requires a VIN conforming to 49 C.F.R. 565 — the 17-character standard. A Japanese chassis number is not that. Ask your county clerk how they handle it, because the answer determines whether you need a state-assigned number and how long the process takes.
Route 2: Class I Off-Highway Vehicle
Tennessee also lets a mini-truck take a Class I off-highway vehicle plate, and the trade is exactly inverted.
A Class I off-highway vehicle is defined as a motorized vehicle with not less than four and not more than six nonhighway tires, whose top speed is greater than 35 mph, limited to a total dry weight of 3,500 lb, 80 inches or less in width, with nonstraddle seating for two to four passengers and a steering wheel.
Measure a kei truck against that and it fits comfortably on every dimension: about 58 inches wide against 80, roughly 1,500–1,900 lb against 3,500, two seats, a steering wheel, and a top speed above 35 that the class positively requires rather than forbids.
The two conditions to weigh:
- Nonhighway tyres. The definition calls for them. Road tyres are what a kei truck arrives on, so this is a fitment decision — and unlike the 35 mph governor, it is cheap and reversible.
- County roads only. A Class I vehicle may be operated on county roads. That is a narrower network than “any street posted 40 or less,” and in a city it is a serious limitation. On rural acreage it may be no limitation at all.
Class I vehicles are also subject to the ordinary requirements applicable to motor vehicles, including Tennessee’s financial responsibility law — so insurance is required on this route too.
Choosing Between Them
| Medium speed vehicle | Class I off-highway vehicle | |
|---|---|---|
| Where you can drive | Any street posted 40 mph or less | County roads |
| Vehicle top speed | Must be limited to 35 mph | Must exceed 35 mph — no limiting |
| Tyres | As fitted | Nonhighway tyres |
| Certification | Affidavit under penalty of perjury | Class I registration |
| Insurance | Required | Required |
| Driver licence | Class D required, in possession | Ordinary licence rules |
| Local override | A county or TDOT may prohibit operation on any road in its jurisdiction | County roads by definition |
The honest way to decide is by where you live rather than by which sounds better. In town, medium speed is usually the usable one — most residential and secondary streets are posted at 40 or less, and a truck limited to 35 is a perfectly good errand vehicle. Usually, not always: the same affidavit states that “in the interest of safety, counties in Tennessee or the Tennessee Department of Transportation may prohibit the operation of medium speed vehicles on any road in its jurisdiction.” A 40 mph posted limit is the ceiling, not a guarantee. Before you commit to a permanent 35 mph modification, ask your county whether it has exercised that power on the roads you actually need, because the modification is not worth making for a route you cannot legally use. On rural land, Class I is the usable one, because county roads are what you are on anyway and you keep the truck’s full capability for the times you need it.
What you should not do is buy first and choose later. The medium speed route costs you a permanent modification; the Class I route costs you a set of tyres and a narrower map. Those are different purchases.
Insurance and Cost
Under the Department of Revenue’s title and registration framework, Tennessee requires liability of at least $25,000 per person, $50,000 per accident and $15,000 property damage, and both registration routes are subject to it.
The usual import friction applies: online quote forms validate VIN length and will reject a Japanese chassis number, so expect a telephone conversation, and ask for an agreed-value policy rather than actual cash value.
Title and registration fees are the ordinary county clerk schedule plus state and local sales tax on the purchase. Tennessee’s combined sales tax rate is among the higher ones in the country, so price it before you buy — on a truck landing around $5,500 it is a real line item rather than a rounding error.
Two cost items worth knowing because they are commonly reported wrongly:
- There is no emissions test. Tennessee’s programme ended on January 14, 2022 in Hamilton, Rutherford, Sumner, Williamson and Wilson counties, and Davidson County — which had voted to keep its own — ended in February 2022. Guides that still tell you to budget for an emissions test in middle Tennessee are quoting a requirement that has not existed for four years. This matters more than the money: a Japanese-market engine has no US emissions certification, and an inspection regime that no longer exists cannot fail you.
- The county wheel tax is the real variable. On top of the state base registration, counties levy a wheel tax that ranges from nothing to roughly $75 a year. It is set locally, it is not in any statewide table, and it can exceed the base registration itself. Ask your county clerk for the all-in annual figure rather than the state number.
For Reference: What These Trucks Cost
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 Tennessee notes on specification, and they follow from the route you pick. If you are going medium speed, buy the cheapest sound truck — you are limiting it to 35 mph anyway, so paying for a turbocharged variant or tall gearing is money spent on capability you are about to certify away. If you are going Class I, buy for capability: 4WD, good gearing, and a healthy engine, because the class exists precisely to let you keep it. Either way, Tennessee is humid and its eastern half sees winter salt, so read the auction sheet for C codes — corrosion that has gone through metal — rather than paint grade, per the auction sheet guide.
Decide the route before you decide the truck — they call for different vehicles. Then condition is the whole question, and CAR FROM JAPAN publishes the inspector’s auction sheet with each vehicle so you can check the glass, the lighting and the corrosion codes before you bid.

FAQ
Are kei trucks legal in Tennessee?
Yes. TCA § 55-1-125 names mini-trucks in its medium speed vehicle definition and covers gasoline as well as electric vehicles. There is also a Class I off-highway vehicle route. Both require registration and insurance.
Do I really have to limit my truck to 35 mph?
If you register it as a medium speed vehicle, yes. The Medium Speed Vehicle Affidavit requires you to certify under penalty of perjury that the vehicle’s top speed is greater than 30 mph but not more than 35. That is a statement about the vehicle, not about how you intend to drive it.
How do I keep the truck’s full speed?
Take the Class I off-highway vehicle route, which requires a top speed above 35 mph. The trade is that Class I operation is limited to county roads, and the class calls for nonhighway tyres.
What equipment does Tennessee require?
For the medium speed route: headlamps, stop lamps, front and rear turn signals, tail lamps, reflex reflectors, a parking brake, two mirrors, a windshield conforming to 49 C.F.R. 571.205 glazing, seat belts at each seating position, and a VIN conforming to 49 C.F.R. 565. The glazing marking and the VIN format are the two worth checking on a specific truck.
Why does Tennessee work when Virginia does not?
Because Virginia requires the manufacturer to certify compliance with FMVSS 571.500, which no Japanese maker will do. Tennessee replaced that with an equipment checklist the applicant certifies. It is the same safety concern handled in a way an imported vehicle can actually satisfy.
What insurance do I need?
$25,000 per person, $50,000 per accident and $15,000 property damage, on either route.
Update, August 19, 2026: added the Class D licence requirement and the county/TDOT power to prohibit medium speed vehicles on specific roads — both are printed on the affidavit this page already relied on, and both were missing. Also added the current position on emissions testing and the county wheel tax, and softened the claim about how other guides cover the 35 mph figure.
