Yes, kei trucks are legal to drive on Michigan roads, as long as the truck is at least 25 years old, was legally imported, and gets titled, registered, and insured like any other vehicle. That answer changed recently. For a stretch, the Michigan Department of State was reclassifying imported Japanese mini-trucks as off-road-only vehicles and denying on-road titles. In late 2024 the department reversed course, and owners who had been forced into ORV titles started receiving new on-road titles by mail.
The 2024 Policy Reversal
Michigan’s vehicle code doesn’t have a dedicated section for kei trucks. It addresses them sideways, through Public Act 680 of 2018, which added Section 217i to the Michigan Vehicle Code and created a pathway for titling “assembled vehicles.” That same section excludes “a gray market off-road minitruck” from the assembled-vehicle definition.1Michigan State Police. MSP Legal Update No. 139 The Department of State read that exclusion broadly and used it to strip on-road status from imported kei trucks.
Attorney Kevin Burton sued on behalf of kei truck owners, arguing that 25-year-old Suzuki Carrys, Honda Actys, and similar vehicles were built for road use in Japan and independently qualified as historic vehicles under other sections of Michigan law. The Department of State’s Vehicle Records Activity Unit later determined that the reclassification had been made in error and began re-issuing on-road titles and registrations for Japanese mini-trucks, micro vans, and kei cars. The practical result: if your kei truck is at least 25 years old and legally imported, Michigan will title and register it for street use.
The 25-Year Federal Import Rule
Before Michigan will touch your paperwork, the truck has to be in the country legally. Federal law generally bars importing a motor vehicle that doesn’t comply with all applicable Federal Motor Vehicle Safety Standards.2Office of the Law Revision Counsel. 49 USC 30112 – Prohibitions on Manufacturing, Selling, and Importing Noncomplying Motor Vehicles Kei trucks were never built to those standards. What makes importation practical is a single exemption: vehicles at least 25 years old are exempt from the FMVSS import ban entirely.3eCFR. 49 CFR 591.5 – Declarations Required for Importation
NHTSA has confirmed that mini-trucks “are not manufactured to meet U.S. safety standards.”4National Highway Traffic Safety Administration. Interpretation ID 09-001270as Without the 25-year exemption, you would need a DOT-registered importer to modify the truck to full FMVSS compliance and post a bond worth 1.5 times its dutiable value.5U.S. Customs and Border Protection. Importing a Motor Vehicle That’s economically pointless on a vehicle worth a few thousand dollars.
There’s also a 25% customs duty on light trucks, often called the chicken tax, that applies regardless of age. On a $4,000 kei truck bought in Japan, that’s roughly $1,000 in duty on top of shipping and broker fees. Importers file CBP Form 7501 to clear the vehicle through customs.6U.S. Customs and Border Protection. CBP Form 7501 – Entry Summary Vehicles that fail to clear must be brought into compliance, exported, or destroyed.
Titling and Registering in Michigan
Michigan requires every motor vehicle driven on a street or highway to be registered and titled.7Michigan Legislature. Michigan Code 257.216 – Michigan Vehicle Code To register a kei truck you’ll need proof of legal importation, proof of ownership (bill of sale, auction receipt, or import documentation), and a VIN inspection by law enforcement.
The VIN piece deserves attention. Japanese kei trucks use a chassis number that may not follow the standard 17-character U.S. format. Federal regulations require importers to use the VIN assigned by the original manufacturer, and if the vehicle came through a registered importer it should have a substitute VIN plate affixed inside the passenger compartment, readable through the windshield.8eCFR. 49 CFR 565.24 – Motor Vehicles Imported into the United States The Michigan inspection verifies the truck matches its paperwork and hasn’t been stolen or altered.
Registration fees follow the weight-based schedule under MCL 257.801. Kei trucks are light, usually under 1,800 pounds empty, which puts them in the lowest bracket. A vehicle up to 3,000 pounds pays $29 in registration tax.9Michigan Legislature. Michigan Code 257.801 – Michigan Vehicle Code Title processing and plate issuance fees are extra.
Standard Plates or Historic Plates
Because kei trucks over 25 years old qualify, you have a choice. Michigan defines a “historic vehicle” as one over 25 years old owned solely as a collector’s item and used for club activities, exhibitions, tours, parades, and similar purposes rather than general daily transportation.10Michigan Legislature. Michigan Code 257.20a – Historic Vehicle Defined Use of the vehicle from Memorial Day weekend through Labor Day counts as exhibition use, which effectively creates a summer driving season.
Historic plates cost $30, and the registration lasts ten years before renewal.11Michigan Legislature. Michigan Code 257.803a – Historic Vehicle Registration Plate Applicants certify the vehicle is used solely as a historic vehicle and has been inspected and found safe. The Secretary of State can revoke the historic registration if the vehicle is used outside the allowed categories.
The decision usually comes down to what you actually plan to do with the truck. If you want a daily-use farm runabout or a landscape hauler, go with standard registration. If it’s a collector piece you drive to shows and around town on summer weekends, historic plates are cheaper and the ten-year renewal cycle is convenient.
Safety Equipment You’ll Need
Michigan’s equipment checklist for assembled vehicles under MCL 257.217i is a useful benchmark for what the state expects on any road-going vehicle: headlamps with high and low beams, front and rear turn signals, at least one working taillight, brake lights, a horn, windshield wipers and washers, functioning brakes, safety belts (for 1965 and newer vehicles), a safety glass windshield, and an adjustable driver-side exterior mirror.12Michigan Legislature. Michigan Code 257.217i – Michigan Vehicle Code Trucks with a half-ton or greater capacity need mirrors on both sides.
Most Japanese-market kei trucks came from the factory with all of this, since Japan’s requirements cover the same basics. The items most likely to need attention are lighting (Japanese-spec headlamps may need swapping for DOT-compliant units), the windshield (check for cracks and confirm it’s safety glass rather than aftermarket plexiglass), and seat belts on early models that shipped with lap belts only. Tires need at least 2/32-inch tread depth and DOT approval markings. Keep receipts and photos of any safety work you do; if the truck goes through a law enforcement inspection during titling, that documentation makes the visit shorter.
Insurance
Any vehicle registered for road use in Michigan must carry liability insurance. The state minimums are $20,000 per person for bodily injury, $40,000 per accident, and $10,000 for property damage.13State of Michigan. Purchasing Auto Insurance FAQ Michigan is a no-fault state, so personal injury protection is part of the picture, though recent reforms let drivers pick from several PIP coverage levels.
Getting an actual policy is the tricky part. Most major carriers don’t have 1990s Japanese mini-trucks in their rating systems, so a standard auto agent may not be able to quote you at all. Specialty and collector-vehicle insurers are usually the better route. They write agreed-value policies, where you and the insurer set the truck’s value up front and that’s what gets paid in a total loss. Collector policies often come with mileage caps and garaging requirements, so read the terms before you sign if you plan to use the truck regularly.
Where You Can Actually Drive It
Registration is one question. What the road looks like once you’re out there is another. Kei trucks typically top out somewhere between 60 and 70 mph depending on the model, but their size, minimal crash protection, and lack of modern safety features make highway driving genuinely riskier than in a full-size truck. Michigan doesn’t impose a separate statutory speed cap on mini-trucks the way some states do, though a kei truck registered under historic plates is limited to the non-transportation uses in the historic-vehicle statute.
Controlled-access highways and interstates are a poor fit regardless of what the law technically allows. Narrow width, light weight, and slow acceleration make merging with 70-mph traffic dangerous. Most kei truck owners stick to surface streets, rural routes, and farm-to-market roads where the truck’s compact dimensions are an asset.
Farm and Off-Road Use
If you never drive the truck on a public road, most of this doesn’t apply. On private property, farms, and construction sites, a kei truck can operate without a title, registration, or insurance. Michigan’s vehicle code exempts implements of husbandry from registration, and it also allows crossing a public road between two parcels without registering.7Michigan Legislature. Michigan Code 257.216 – Michigan Vehicle Code Whether a kei truck qualifies as an implement of husbandry depends on how it’s used and configured; a dump-bed truck working exclusively on a farm has a stronger case than one parked in a suburban driveway.
Off-road use skips the safety and titling complications, but the 25% customs duty at import still applies, and you’ll still need valid proof of legal entry.
Buying One That’s Already Here
The most common mistake isn’t intentional fraud. It’s buying a kei truck domestically from someone who cut corners on the import process. If the truck was never properly entered through customs, or if the seller used bad documentation to get a title, the problem stays with the vehicle. Before buying, verify the import paperwork, check that the VIN matches federal and state records, and confirm the title is clean.
The federal side has teeth. CBP can require non-conforming vehicles to be brought into compliance, exported, or destroyed, and vehicles temporarily imported under bond that aren’t exported within 90 days are subject to forfeiture.5U.S. Customs and Border Protection. Importing a Motor Vehicle State-level consequences for driving unregistered or uninsured include fines, impoundment, and license suspension. A cheap kei truck stops being cheap fast if the paperwork behind it doesn’t hold up.
