Is a Kei Truck Street Legal in Michigan?

What does Michigan law say about Kei Trucks?

Michigan treats a Kei Truck as street legal once it reaches 25 years of age. The Michigan Department of State, the agency behind Secretary of State (SOS) offices, answers the question in its title FAQ. The answer covers Kei-class vehicles, naming mini trucks and microvans, and says those 25 or older can get an on-road title and registration as long as they were originally built for road use, whether in the US or overseas. A truck that spent its working life on Japanese plates meets that condition.

The same FAQ draws a firm line. A mini truck or microvan younger than 25 is not eligible for a Michigan road title or registration, and the only title on offer is an off-road one. Federal import law uses the same age line, so read our 25-year rule page before you bid on anything near the cutoff. Build month matters more than model year.

Where can you drive a Kei Truck in Michigan?

With an on-road title and plates, a Kei Truck faces no Kei-specific limits in Michigan: no posted-speed cap, no interstate ban and no local opt-in. It follows the same traffic code as any light truck. Most owners still keep these trucks on county roads, two-lane highways and their own land, where a 660 cc engine and a short wheelbase make sense.

What changed in Michigan in 2024?

During 2024 the state pulled road status from a number of imported mini trucks. Owners received letters saying their road titles had been issued in error, and the titles were converted to off-road titles. The legal hook was MCL 257.217i, a 2018 law on assembled vehicles that excludes a "gray market off-road minitruck" from that category.

Owners pushed back, and in late 2024 the department began reinstating on-road titles. The current FAQ answer, which applies the 25-year test to Kei-class vehicles by name, is the policy in force as of October 2026. Because it is written guidance rather than a statute, keep a printed copy with your paperwork.

What paperwork does Michigan want for an imported Kei Truck?

For a vehicle brought in from another country, the SOS lists ownership documents, the entry summary (Form 7501) from US Customs and Border Protection (CBP), the HS-7 safety-standards declaration from the US Department of Transportation (DOT), the Environmental Protection Agency (EPA) Form 3520-1 emissions declaration, your driver's license or state ID, and proof of Michigan no-fault insurance. Two details save a second trip. A Customs stamp on the 7501 is not required for a vehicle 25 years old. Form TR-54, an inspection form, comes into play only when the vehicle entered the US through another state and you are titling it without registering it.

Do not let the rest of Michigan's import FAQ scare you off. Its talk of registered importers, statements of conformity and bond release letters describes vehicles declared under HS-7 box 3, the route for imports that must be modified to meet US standards. A 25-year-old Kei Truck comes in under box 1, the age exemption. Our guide to importing a Kei Truck walks through each federal form.

1. Confirm the truck is 25 years old

   Check the build date on the truck and its papers. Michigan's on-road rule and the federal import exemption both start at 25 years, and a truck even a month short gets only an off-road title.

2. Collect the federal import forms

   Keep the CBP 7501 entry summary, the EPA 3520-1 and the HS-7 from DOT with box 1 marked. A Customs stamp on the 7501 is not needed for a vehicle 25 years old.

3. Prepare the ownership papers

   Bring the Japanese export certificate and your bill of sale. The SOS list does not spell out translation rules, so a certified English translation is a sensible precaution.

4. Buy Michigan no-fault insurance

   Arrange a no-fault policy before the office visit, since proof of Michigan no-fault coverage is on the SOS document list.

5. Visit a Secretary of State office

   Bring your license or state ID with the papers above, apply for the on-road title and register the truck. Form TR-54 applies only if the vehicle entered through another state and you are titling it without registering.

Does Michigan inspect Kei Trucks, and what does registration cost?

Michigan does not inspect cars or light trucks on a schedule, and it has no emissions testing program, so nobody checks the truck after it is plated. That puts the job on you. Our buying guide and maintenance guide cover what to look at, and in a road-salt state the frame, bed seams, brake lines and fuel lines come first. Fresh brake parts and working lights are cheap protection on a truck no inspector will see.

Michigan's registration tax for most vehicles is figured from list price. Under MCL 257.801, when the SOS has no published base price and no federal window sticker exists, the purchase price is used instead, so an inexpensive import lands in a low bracket. Title and plate fees are separate. Insurance comes before plates, and some insurers will only quote a Japanese chassis number by phone.

Elsewhere in the Upper Midwest the answer can be very different. Minnesota gives mini trucks no state plates at all and leaves road use to local permits. See every state on the Kei Truck law map, and confirm current requirements at an SOS office before you ship.
