Tennessee kei truck registration guide
Medium speed vehicle or Class I OHV · two pathways
Tennessee offers two registration routes for a kei truck, and which one you choose determines where you can legally drive. The 'medium speed vehicle' class explicitly includes mini trucks; Class I off-highway plates are the alternative for county road use.
Bottom line for Tennessee
- TCA 55-1-125 defines a medium speed vehicle as a four-wheeled vehicle topping out above 30 but not above 35 mph, expressly including mini trucks.
- Medium speed vehicles must meet or exceed the federal standards in 49 CFR 571.500.
- A low or medium speed vehicle affidavit must be submitted when registering.
- Class I off-highway plates under TCA 55-8-191 are a separate route allowing county road operation.

Two pathways
Medium speed vehicle vs. Class I OHV
The medium speed vehicle class is defined in TCA 55-1-125 as a four-wheeled electric or gasoline vehicle whose top speed exceeds 30 mph but does not exceed 35 mph — and the definition expressly names mini trucks. Vehicles registered this way must meet or exceed the federal standards at 49 CFR 571.500, and road use is tied to lower-speed streets.
The alternative is a Class I off-highway vehicle plate under TCA 55-8-191, which permits operation on county roads. Which route serves you better depends almost entirely on where you intend to drive, so decide that before you go to the county clerk.

Titling & registration steps

Decide which class you are registering under
Medium speed vehicle (TCA 55-1-125) or Class I off-highway vehicle (TCA 55-8-191). The choice governs where you may operate, and switching later means re-registering.

Title and register at your county clerk

FAQ
Common questions
- Are kei trucks street legal in Tennessee?
- Yes, through one of two pathways. TCA 55-1-125 defines a medium speed vehicle — expressly including mini trucks — as a four-wheeled vehicle topping out above 30 but not above 35 mph. Alternatively, Class I off-highway plates under TCA 55-8-191 permit county road operation.
- Which registration class should I choose?
- It depends where you plan to drive. Medium speed vehicle registration ties you to lower-speed streets with a 35 mph operating cap. Class I OHV plates are oriented toward county roads. Decide before you visit the county clerk, since changing later means re-registering.
- What is 49 CFR 571.500?
- It is the federal low-speed vehicle standard. Tennessee requires medium speed vehicles to meet or exceed it, which covers equipment such as lighting, mirrors, seat belts, and a VIN. Confirm your specific vehicle's compliance before registering.
- Do I register at the DMV or the county clerk?
- Tennessee vehicle registration is handled by county clerks. The Department of Revenue sets statewide policy; your county clerk processes the application and the affidavit.
- Is the affidavit mandatory?
- Yes. Tennessee requires submission of the low or medium speed vehicle affidavit when registering a vehicle in that class.
- Can I drive on the interstate?
- No. A medium speed vehicle is capped at 35 mph by definition, and neither pathway contemplates interstate or controlled-access highway operation.
Tennessee county clerks apply these classifications with some variation, and the medium speed vehicle road conditions should be confirmed locally. Verify current requirements with your county clerk before purchasing. This page is informational only and not legal advice.
