Illinois
Not LegalActive crackdown: the Secretary of State began revoking existing kei truck plates and branding titles 'Not Eligible For Registration' starting April 2025, citing IVC §3-401(c-1). No path to new registration exists, and appeals have not succeeded.
Important: Kei laws change frequently and vary by county. Always confirm with your state DMV before purchasing.
Key Restrictions
No registration pathway. Illinois Vehicle Code §3-401(c-1) requires a vehicle to have been originally manufactured for highway operation to be registered — the Secretary of State's office has stated kei trucks don't qualify unless legislation specifically allows it.
Registration Process
New on-road registration is not available in Illinois, and this is an active enforcement situation rather than a passive ban.
What's Happening
Starting in April 2025, the Illinois Secretary of State's office began revoking plates and branding titles "Not Eligible For Registration" for kei trucks — including vehicles that had been registered for years without issue. The office cites IVC §3-401(c-1), which bars registration of a vehicle not originally manufactured for highway operation.
If Your Plates Are Revoked
Owners have appealed through administrative hearings since June 2025, but outcomes have not been favorable, and some owners have reported being threatened with vehicle impoundment or crushing at their own expense. If you receive a revocation notice, consult an attorney before responding.
Do Not Purchase for Illinois Road Use
Unless and until the General Assembly passes legislation specifically permitting kei truck registration, do not purchase a kei truck expecting to register or keep it registered for Illinois road use — even an existing registration is not safe from revocation.
Insurance Information
Standard road insurance does not apply to a vehicle that cannot be legally registered. If you're using a kei truck strictly on private property, consult your property insurer about off-road equipment coverage.
Exemptions
[VERIFY: private-property/off-road use — contact the Illinois Secretary of State's office directly]
Legislative Activity
No remedial legislation has been introduced to reverse the Secretary of State's position as of August 2026.
Additional Notes
Illinois is a materially different situation from most other "not-legal" states: this isn't just a denial for new applicants, it's active revocation of registrations that were previously issued and relied upon. Treat any Illinois-titled kei truck for sale with caution — verify its registration status directly with the Secretary of State before purchasing, don't just trust the plate on the vehicle.
Common Issues
Some owners report their vehicles were flagged years after original registration, with no warning beyond a revocation letter. Sellers advertising a "currently registered" Illinois kei truck may not disclose that the registration is at risk. Confirm status independently before buying.
Required Documents
- Registration is not currently available — do not purchase for Illinois road use
- If already registered, be aware existing plates/titles are subject to active revocation
