Kei Truck & Kei Car Laws in Massachusetts (2025)

Legal

Are Kei Trucks Legal in Massachusetts?

Yes, kei trucks are legal in Massachusetts! After a brief and controversial ban in mid-2024, Massachusetts reversed course and fully legalized kei vehicles 25 years or older for on-road use. As of September 18, 2024, the Massachusetts Registry of Motor Vehicles (RMV) allows owners to register and title kei trucks, including popular models like the Suzuki Carry, Honda Acty, and Daihatsu Hijet.

This reversal came after significant public pressure and advocacy from groups like the Massachusetts JDM Imports Advocates. The RMV initially announced it would stop registering kei vehicles, sparking outrage from owners who had legally imported and registered their vehicles. For more details, check our complete guide to importing a kei truck from Japan. The state quickly reconsidered, announcing in September 2024 that kei vehicles would continue to be registrable.

Massachusetts now joins the growing list of states recognizing these Japanese mini trucks as legitimate on-road vehicles. The state honors the federal NHTSA 25-year import rule, which allows vehicles 25 years or older to be imported regardless of U.S. safety standards.

However, there's an important nationwide restriction: kei trucks are not authorized to travel on interstate highways in any state, including Massachusetts. This limits their use to state highways, county roads, and local streets.

How to Register a Kei Truck in Massachusetts

Registering a kei truck in Massachusetts follows a similar process to standard vehicles, with a few specific requirements:

Required Documents:

  • Certificate of title or manufacturer's certificate of origin (for newly imported vehicles)
  • Bill of sale showing purchase price
  • Federal customs clearance documents (Form 3520-1 and HS-7 declaration)
  • Proof of Massachusetts residency
  • Valid Massachusetts driver's license or ID
  • Proof of insurance (must be obtained before registration)

Registration Process:

  1. Obtain Insurance: You must have an active Massachusetts auto insurance policy before registering. Minimum coverage requirements are:

    • $20,000 bodily injury per person
    • $40,000 bodily injury per accident
    • $5,000 property damage
  2. Complete Safety Inspection: Take your kei truck to a licensed Massachusetts inspection station. The vehicle must pass safety inspection before registration.

  3. Visit an RMV Service Center: You cannot register a newly imported kei truck online. Visit your local RMV office with all required documents.

  4. Complete Form RMV-1: Fill out the Registration and Title Application form. Indicate whether you'll use passenger or commercial plates based on your intended use.

  5. Pay Fees and Taxes: Massachusetts charges registration fees and excise tax based on vehicle value.

  6. Receive Plates and Registration: You'll receive either passenger or commercial plates, a registration certificate, and a title.

Costs Breakdown:

  • Title fee: $75
  • Registration fee: $60 for two years (passenger plates)
  • Sales tax: 6.25% of purchase price (may vary for used imports)
  • Excise tax: Varies by municipality and vehicle value
  • Safety inspection: $35
  • Emissions inspection: $35 (if required in your area)

Total estimated first-year cost: $300-$600 depending on vehicle value and location.

Important Notes:

  • Kei vehicles already registered before the 2024 ban may continue their existing registration without interruption
  • Newly imported vehicles need full documentation proving 25+ year age and legal importation
  • Commercial plates are required if you plan to use the truck for business purposes

Restrictions and Limitations

While Massachusetts allows kei trucks on most roads, there are important restrictions:

Highway Restrictions:

  • No interstate highway use (federal restriction applying nationwide)
  • State highways and Route 2, Route 9, and similar roads are generally permitted
  • Local roads and streets are fully accessible

Speed Considerations:

  • Most kei trucks have a top speed of 50-65 mph
  • Avoid roads where minimum speed limits exceed your vehicle's capability
  • Be cautious on high-speed state routes where traffic moves significantly faster

Equipment Requirements:

Massachusetts requires all registered vehicles to have:

  • Working headlights and taillights
  • Turn signals (front and rear)
  • Brake lights
  • Horn
  • Windshield with functioning wipers
  • Rearview mirrors (at least one on driver's side)
  • Seat belts for all passengers
  • License plate lights

Many imported kei trucks require modifications to meet these standards, particularly:

  • Adding or upgrading turn signals to meet U.S. standards
  • Installing DOT-compliant lighting
  • Ensuring all lights are amber (front) and red (rear) as required

Use Classification:

  • Passenger plates: Personal use, commuting, recreation
  • Commercial plates: Business use, hauling goods, contractor work

RMV Ongoing Review:

The Massachusetts RMV has stated it will continue reviewing the safety implications of kei vehicles on public roadways and plans to conduct a formal study. While this doesn't affect current registrations, owners should stay informed about potential future regulatory changes.

Insurance Requirements

Massachusetts has mandatory auto insurance requirements, and kei trucks are no exception. For more guidance, see our kei truck insurance guide.

Minimum Required Coverage:

  • $20,000 bodily injury liability per person
  • $40,000 bodily injury liability per accident
  • $5,000 property damage liability per accident
  • Personal injury protection (PIP) as required by Massachusetts no-fault law

Finding Insurance:

Not all insurance companies are familiar with kei trucks. Based on owner experiences and industry knowledge:

Companies That May Cover Kei Trucks:

  • Hagerty - Specializes in collector and specialty vehicles; frequently mentioned by kei truck owners
  • Progressive - Some owners report success; requires agent contact
  • State Farm - Hit or miss; depends on local agent familiarity
  • Safety Insurance - Massachusetts-based company that may be more flexible
  • Arbella Insurance - Another Massachusetts insurer worth trying

Tips for Getting Insurance:

  • Call and speak with an agent rather than using online quotes
  • Explain that your vehicle is a legally imported Japanese utility truck
  • Have your VIN/chassis number, import documents, and photos ready
  • Mention that it's federally legal under the 25-year rule
  • Be prepared to get "specialty vehicle" or "collector car" coverage

Expected Costs:

Insurance for kei trucks typically runs $300-$800 per year, depending on:

  • Your driving record
  • Location (urban vs. rural)
  • Coverage limits beyond minimum requirements
  • Declared value of the vehicle

Some insurers may require an agreed value appraisal for higher-value kei trucks or rare models.

Inspection and Emissions

Massachusetts requires annual safety inspections for all registered vehicles. Depending on your location, emissions testing may also be required.

Annual Safety Inspection:

  • Cost: $35
  • Required annually
  • Must be performed at a licensed inspection station
  • Results in a color-coded sticker displayed on windshield

Inspection Checklist:

Massachusetts inspectors will check:

  • Brake system (function and condition)
  • Steering and suspension
  • Tires (tread depth, condition, proper size)
  • Windshield (no cracks in driver's vision area)
  • Wipers and washer fluid
  • Horn
  • All lights (headlights, taillights, brake lights, turn signals, license plate light)
  • Mirrors
  • Seat belts
  • Exhaust system (no excessive noise or leaks)
  • Frame and body (structural integrity, no sharp edges)

Emissions Testing:

Massachusetts requires emissions testing in certain areas. However:

  • Vehicles 15 years or older may be exempt from emissions testing
  • Since most kei trucks entering the U.S. are 25+ years old, they typically qualify for exemption
  • Check with your inspection station to confirm your vehicle's exemption status

Common Inspection Issues:

Based on owner experiences, kei trucks may fail inspection for:

  • Turn signals not meeting U.S. standards: Japanese turn signals may be wrong color or location
  • Lighting issues: Bulbs out or wiring problems from age
  • Windshield cracks or chips: Common in older imports
  • Tire condition: Imported tires may be aged or non-compliant

Preparation Tips:

  • Have a mechanic familiar with imports check your truck before inspection
  • Replace any questionable lighting components
  • Ensure all bulbs are working
  • Fix any windshield damage before inspection
  • Check tire date codes (tires older than 6-10 years should be replaced)

Tips from Massachusetts Kei Truck Owners

Finding Inspection Stations:

Winter Driving:

  • Kei trucks handle Massachusetts winters surprisingly well, especially 4WD models

  • Some towns have active kei truck owner communities

Modifications and Parts:

  • Join Massachusetts-based JDM import groups for local mechanics

Best Uses:

  • Urban delivery and small business operations
  • Farm and property maintenance
  • Beach and outdoor recreation (avoid sand without proper prep)
  • Farmers markets and mobile vending

Frequently Asked Questions

Can I drive my kei truck on the Mass Pike or I-95?

No. Federal restrictions prohibit kei trucks from interstate highways nationwide. This includes I-90 (Massachusetts Turnpike), I-95, I-91, I-93, and all other interstate routes. You can use state routes like Route 2, Route 9, Route 20, and similar roads, but avoid interstates.

Do I need a special license to drive a kei truck?

No. A standard Massachusetts Class D driver's license is sufficient. Kei trucks are four-wheeled motor vehicles, so no special endorsements or commercial licenses are required for personal use.

Can I use a kei truck for my landscaping or construction business?

Yes. You'll need to register with commercial plates and ensure your insurance covers commercial use. Many Massachusetts landscapers, contractors, and small business owners use kei trucks for local work. Just remember you can't take interstate highways to job sites.

What if I get pulled over?

As long as your registration, insurance, and inspection are current, you shouldn't have issues. Some police officers may be unfamiliar with kei trucks, so keep your import documentation and registration in the vehicle. Be polite and explain that the vehicle is legally registered with the Massachusetts RMV.

Are older kei trucks easier to register?

Age doesn't matter for registration eligibility as long as the vehicle is 25+ years old (meeting federal import requirements). However, older vehicles may have more difficulty passing safety inspection due to wear, outdated lighting, or rust.

Can I register a kei truck I bought from another state?

Yes. If you're bringing a kei truck from another state, you'll need to re-register it in Massachusetts. Bring the out-of-state title, bill of sale, and all import documentation to the RMV. You'll need to pass Massachusetts inspection and obtain local insurance.

What's the difference between passenger and commercial plates?

Passenger plates are for personal use (commuting, errands, recreation). Commercial plates are required if you use the vehicle for business purposes (delivering goods, hauling equipment, contractor work). Commercial registration may have different fee structures and insurance requirements.
