Kei trucks, known for their compact size and fuel efficiency, have garnered interest in the U.S. However, potential owners in Illinois must navigate specific regulations and requirements to determine if these vehicles can be legally driven on state roads. This blog post will provide a detailed examination of the legal landscape for kei trucks in Illinois, exploring federal and state regulations, necessary documentation, and the process for registering and titling these unique vehicles.

Understanding Kei Trucks

Kei trucks, or mini trucks, are a class of small vehicles from Japan, typically equipped with engines under 660cc. These trucks are known for their versatility, often used in agriculture, construction, and small business operations due to their compact size and efficiency. However, their unique design and specifications pose challenges when it comes to meeting U.S. safety and emissions standards.

Federal Regulations

Before diving into state-specific regulations, it's essential to understand the federal requirements for importing and legalizing kei trucks in the U.S. The National Highway Traffic Safety Administration (NHTSA) and the Environmental Protection Agency (EPA) set stringent standards that imported vehicles must meet.

  1. Customs Form 7501: This "Entry Summary" form is provided to the importer at the port of entry and must be signed by the importer.
  2. DOT Form HS-7: This form certifies that the vehicle conforms to federal motor vehicle safety standards. It is crucial for vehicles not originally manufactured to comply with U.S. standards.
  3. EPA Form 3520-1: This form acknowledges that the vehicle meets U.S. emissions standards. Vehicles must either conform to these standards or be exempt.

These forms are critical for titling and registering any imported vehicle, including kei trucks.

Illinois-Specific Regulations

In Illinois, the legal framework for kei trucks follows general guidelines for importing foreign vehicles but adds specific state-level requirements.

  1. Application for Vehicle Transaction (VSD190): This form is necessary if the vehicle will not be operated immediately.
  2. Motor Vehicle Tax Forms (RUT-25 or RUT-50): These forms are required to calculate and pay the necessary taxes.
  3. Ownership Documents: Original foreign documents of ownership must be in English or accompanied by a certified translation. A bill of sale is required if the sale occurred in a foreign country, detailing the year, model, make, VIN, and purchase price.
  4. Federal Compliance: Vehicles must have either a Federal Certification Label (FCL) or a Registered Importer (RI) label to show compliance with U.S. safety and emissions standards. Vehicles without these labels will be branded "NON USA STANDARD" on the title and can only be registered as special interest or collector vehicles.

For kei trucks, these steps are essential to ensure the vehicle meets all regulatory requirements before being used on public roads in Illinois.

Collector Plates and Limited Use

In Illinois, kei trucks without federal compliance labels can be titled but will display "NON USA STANDARD" on their titles. These vehicles may only be registered as special interest or collector vehicles. This limitation means that while kei trucks can be owned and operated under specific conditions, they are not generally permitted for regular on-road use.

Real-Life Experiences and Practical Use

Many kei truck enthusiasts in Illinois have shared their experiences navigating these regulations. While the process can be complex, understanding the requirements and working with experienced importers can simplify the process. Additionally, kei trucks can be highly practical for off-road uses, such as on farms or private properties, where federal and state road regulations do not apply.


Navigating the legal landscape for kei trucks in Illinois requires careful attention to both federal and state regulations. While these unique vehicles face restrictions, particularly for on-road use, they remain a popular and practical option for off-road and specialized applications. By understanding the necessary documentation and compliance requirements, kei truck owners can ensure their vehicles are legally operated within Illinois. Stay informed, consult with experts, and connect with the kei truck community to successfully manage the process and enjoy the benefits of these versatile vehicles.
