Kentucky kei truck registration guide

The Act lists the equipment a special purpose vehicle must have to be street-legal:

• •One or more headlamps, tail lamps, and brake lamps
• •A lamp placed to illuminate the registration plate with a white light
• •One or more red reflectors on the rear
• •Amber electric turn signals on each side of the front, and amber or red electric turn signals on the rear
• •A braking system other than a parking brake
• •A horn or other warning device
• •A working muffler
• •Rearview mirrors on the right and left side of the driver
• •A windshield, unless the operator wears eye protection
• •A speedometer, illuminated for nighttime operation
• •A roll bar or roll cage
• •For multi-passenger vehicles, a seatbelt assembly conforming to 49 C.F.R. § 571.209 for each designated seating position
• •Tires with at least 2/32 of an inch of tread

The equipment list was plainly drafted with ATVs and side-by-sides in mind, and most of it is easy for a kei truck — a factory kei truck already has headlamps, tail lamps, turn signals, mirrors, a windshield, a speedometer, and a muffler. The item that does not obviously map is the roll bar or roll cage.

A kei truck has an enclosed steel cab rather than a bolt-on roll structure. Whether an inspector or county clerk treats that cab as satisfying the requirement, requires an added roll bar, or reads the requirement as inapplicable to a vehicle with a cab, is not addressed in the Act. The Act directs the Transportation Cabinet to promulgate administrative regulations implementing the section, so this may be resolved in regulation — check for current regulations rather than assuming.

This is the question to settle in writing with your county clerk and a certified inspector before you buy. It is the difference between a registrable vehicle and an expensive off-road one.

1. 1

   Check your local ordinance first

   A street-legal special purpose vehicle may not be operated on a highway inside the jurisdiction of a local government that has not passed an ordinance allowing it. Local governments may also adopt stricter equipment and operation rules than the state minimum. Confirm your city or county has opted in before anything else.

2. 2

   Clear federal import

   Import a vehicle at least 25 years old and retain CBP Form 7501, NHTSA Form HS-7 (Box 1), EPA Form 3520-1, and the Japanese title or export certificate with certified translation.

3. 3

   Bring the vehicle to the equipment standard

   Work through the statutory equipment list, and settle the roll bar or roll cage question with your inspector before spending on anything else.

4. 4

   Obtain a certified inspection

   The Act amends KRS 186A.115 to require an owner of a street-legal special purpose vehicle to have the vehicle inspected by a certified inspector before submitting the application.

5. 5

   Insure at motorcycle levels

   The owner or operator must insure the vehicle for tort liabilities in the same form and amounts as KRS 304.39-110 requires for motorcycles.

6. 6

   Register with the county clerk

   Register under the amended KRS 186.020 through the county clerk. The annual registration fee for a street-legal special purpose vehicle is $10 under the amended KRS 186.050, and the clerk issues a motorcycle registration plate for the vehicle.

At renewal, the applicant must certify that the vehicle still meets all of the equipment requirements.

SB 63 did not repeal KRS 189.517, which defines a mini-truck as a lightweight Japanese kei class utility vehicle and prohibits operating one on a public highway or right-of-way except in specific cases: crossing a two-lane highway at close to a right angle and travelling no more than two-tenths of a mile on it, or operating on a two-lane highway while engaged in farm or agricultural activities, construction, road maintenance, or snow removal.

That section also requires a valid operator's license, compliance with traffic regulations, at least two headlights and two taillights illuminated at all times, and restricts operation to daylight hours except during snow removal or emergency road maintenance. It further allows the Transportation Cabinet, a city, or a county to designate highways where otherwise-prohibited mini-trucks may be operated.

In practice, KRS 189.517 is the fallback if your vehicle is not registered as a street-legal special purpose vehicle, or if your local government has not opted in. It is a farm and utility allowance, not general road use.

Are kei trucks street legal in Kentucky?

They can be, since 2025. SB 63 (2025 Ky. Acts ch. 89) created a street-legal special purpose vehicle class whose definition expressly includes minitrucks, and a qualifying vehicle is registered through the county clerk. But road use requires a local ordinance allowing it, and several restrictions apply on top.

Isn't Kentucky listed as a prohibited state?

That listing is out of date. It reflects KRS 189.517, which has barred mini-trucks from public highways since 2013 and is still in force for unregistered vehicles. SB 63 added a separate registration pathway in 2025 that those listings have not caught up with.

What is the roll bar or roll cage issue?

The statutory equipment list requires a roll bar or roll cage. That was written with ATVs and side-by-sides in mind, and a kei truck has an enclosed steel cab rather than a roll structure. Nothing in the Act says whether a factory cab satisfies the requirement. Settle this in writing with your county clerk and a certified inspector before buying — it is the one item that could stop the whole process.

Do I need my city or county to approve it?

Yes. A street-legal special purpose vehicle may not be operated on a highway within a local government that has not adopted an ordinance allowing special purpose vehicle use. Local governments may also impose stricter equipment and operating rules than the state. Check your specific jurisdiction first.

How far can I actually drive?

Street-legal special purpose vehicles may not travel more than 20 miles on a highway displaying centerline pavement markings, and may not use controlled-access routes such as interstates and parkways. Minitrucks carry an extra restriction the other special purpose vehicles do not: they may not be operated as street-legal special purpose vehicles on any highway constructed pursuant to a federal highway program.

What plate and insurance do I get?

On registration the county clerk issues a motorcycle registration plate. The owner or operator must insure the vehicle for tort liabilities in the same form and amounts KRS 304.39-110 requires for motorcycles. The annual registration fee is $10.

What if my county has not opted in?

Then KRS 189.517 is your position: no public highway operation except crossing a two-lane highway at close to a right angle for no more than two-tenths of a mile, or operating on a two-lane highway while engaged in farm or agricultural activities, construction, road maintenance, or snow removal — in daylight, with a valid operator's license and two headlights and two taillights lit.

SB 63 is recent law and the Transportation Cabinet is directed to promulgate implementing regulations, so county clerk and inspector practice may still be settling. Two points are genuinely unresolved: whether a factory kei truck cab satisfies the statutory roll bar or roll cage requirement, and which local governments have adopted enabling ordinances — there is no central registry of those. Confirm both in writing with your county clerk before purchasing. This page is informational only and not legal advice.
