Are Kei Trucks Legal in Texas? Import, Title, and Road Rules

Kei trucks are legal in Texas. You can title, register, and drive one on public roads under Senate Bill 1816, which took effect September 1, 2025, and treats these vehicles as motor vehicles for titling and registration.¹ The catch sits upstream of Texas: federal law generally requires the truck to be at least 25 years old before it can enter the country, and several layers of paperwork and inspection stand between the port of entry and a Texas license plate.

SB 1816 created a category called a “miniature vehicle” in Section 502.001 of the Transportation Code, defined as a self-propelled motor vehicle with four or more tires that complies with applicable federal law. The definition excludes custom vehicles, street rods, neighborhood electric vehicles, golf carts, and off-highway vehicles.¹ A kei truck that fits the definition is treated like any other motor vehicle when you walk into a county tax assessor-collector’s office.

The 25-Year Federal Import Rule

Before Texas will do anything with your kei truck, it has to be legally in the country. The National Highway Traffic Safety Administration requires imported motor vehicles to meet Federal Motor Vehicle Safety Standards unless an exemption applies. Under 49 CFR 591.5, a vehicle that is 25 or more years old can be imported without meeting those standards.² The 25-year clock runs from the date of manufacture printed on the original manufacturer’s label.³

The EPA has a separate 21-year emissions exemption that applies only if the vehicle remains in its original, unmodified condition; a replacement engine kills the exemption unless the swap is an equivalent or newer EPA-certified engine with matching emission controls.³ The DOT threshold is the binding one for street use, which is why nearly every kei truck offered for sale in the U.S. is at least a quarter century old.

A kei truck less than 25 years old would need to comply with full FMVSS safety standards, and the general prohibition on importing noncompliant vehicles is spelled out in 49 U.S.C. 30112.⁴ These trucks were built for Japan’s domestic market and not to U.S. crash-test or emissions specs, so bringing a newer one into compliance is prohibitively expensive for most buyers.

Import Paperwork and the Chicken Tax

Two federal forms have to be filed with U.S. Customs and Border Protection at the port of entry. Miss either one and the vehicle stays in customs.

NHTSA Form HS-7, the DOT import declaration, which requires you to declare the legal basis for entry. For a 25-year-old kei truck, that’s the age-based exemption box.⁵
EPA Form 3520-1, the emissions declaration. For the age exemption, you file using code “E.”³

Then there is the tariff. The United States applies a 25% duty on imported light trucks under Harmonized Tariff Schedule heading 8704, a levy commonly called the Chicken Tax. Japan has no trade agreement that reduces it, so kei trucks are hit at the full rate.⁶ On a truck with a declared customs value of $5,000, that’s $1,250 in duty alone, before shipping, brokerage, or customs processing fees. If the truck can be classified as a passenger vehicle under heading 8703, the general rate drops to 2.5%, but classification depends on the vehicle’s design and features and is a question for a customs broker familiar with Japanese imports.

Getting a Texas Title

Once the truck is through customs, the state-side process runs through your county tax assessor-collector’s office. The TxDMV’s Registration and Title Bulletin #001-24 lists what to bring:

Evidence of ownership: a foreign title or registration assigned to you, a bill of sale, or an out-of-state title if the truck was previously titled in another state.
Application for Texas Title and/or Registration (Form 130-U).
Government-issued photo identification.
Law Enforcement VIN Inspection (Form VTR-68-A) if the vehicle was last titled or registered in another country. A standard VIN verification is enough if it was last titled in another U.S. state.
Proof of U.S. Customs entry and clearance.
Proof of Form HS-7 filing.

If any import document is missing, the county office cannot issue a title, and there is no workaround. Unlike some other Texas titling situations, you cannot fix missing import paperwork through a bonded title or a tax assessor-collector hearing.⁷ Confirm the seller has customs entry proof and the HS-7 before you hand over money.

If the surrendered ownership documents indicate the vehicle is for off-highway use only, the Texas title will carry a permanent off-highway-use remark, and the truck will not be eligible for registration or road use.

Sales Tax, Registration Fees, and Insurance

Texas charges a 6.25% motor vehicle sales tax on the purchase price.⁸ For private-party purchases, tax is calculated on the higher of the actual price paid or 80% of the state’s Standard Presumptive Value. Many kei trucks don’t appear in the SPV database, and if the SPV figure looks too high you can obtain a certified appraisal using Form 14-128 within 30 days of purchase to establish a lower taxable value.⁹

Kei trucks weigh well under 6,000 pounds, so the annual registration fee is $50.75 plus local county fees ranging from $1.50 to $21.50, putting the yearly total in the neighborhood of $52 to $72.¹⁰

You’ll also need liability insurance meeting Texas minimums before registration will go through: $30,000 for bodily injury or death per person, $60,000 per accident, and $25,000 for property damage.¹¹ Finding a carrier willing to write a policy on a 25-year-old Japanese mini truck can take some shopping. Specialty importers and kei truck owner communities are useful starting points for carrier recommendations.

Safety and Emissions Inspections

Texas requires a passing safety inspection on record in the Department of Public Safety’s database before the county office will register the vehicle, under Section 501.030 of the Transportation Code.¹² Stations check lights, brakes, mirrors, tires, and horn.

Emissions testing is only required in certain counties. As of 2026, the affected counties are:

Houston-Galveston-Brazoria area: Brazoria, Fort Bend, Galveston, Harris, and Montgomery
Dallas-Fort Worth area: Collin, Dallas, Denton, Ellis, Johnson, Kaufman, Parker, Rockwall, and Tarrant
Austin area: Travis and Williamson
El Paso area: El Paso
San Antonio area: Bexar (beginning November 1, 2026)

Registering in a county not on that list means safety inspection only.¹³ Most kei trucks old enough to clear the 25-year import rule will also qualify for the emissions-testing age exemption these counties apply to older vehicles, though the specific cutoff varies by program area.

Where a Kei Truck Can Actually Go

SB 1816 added Section 545.429 to the Transportation Code, allowing a properly titled and registered miniature vehicle to operate on any public highway as long as it is capable of complying with applicable traffic laws.¹ That last phrase is where the statute meets the road.

Most kei trucks have top speeds between 55 and 70 mph depending on model and condition. Texas doesn’t impose a blanket highway ban on miniature vehicles, but a truck that can’t hold the minimum safe speed for a given road isn’t legally operating in compliance on that road. City streets, rural roads, ranch-to-town runs, and lower-speed state highways work well. Interstate driving in a vehicle with a 660cc engine is technically permitted on paper but uncomfortably marginal in practice.

Off-Road-Only Ownership

If you plan to use the truck exclusively on a farm, ranch, hunting property, or industrial site, you still need a Texas title for proof of ownership, but the title will carry an off-highway-use remark and the vehicle will not be registered for road use.⁷ Federal import requirements still apply regardless of intended use. What you skip at the state level is the safety inspection, emissions testing, and liability insurance, because none of those attach to a vehicle that won’t be registered. If you change your mind later, the off-highway remark has to be addressed with the county office and the truck has to meet every requirement any other miniature vehicle faces.

Mistakes That Block Registration

The most frequent problem is missing import paperwork. Buyers who purchase kei trucks domestically from a reseller or at auction sometimes receive a bill of sale but no customs clearance documentation or HS-7 proof. Without those federal documents, the county office will refuse to issue a title.⁷

The second common issue is engine swaps. A kei truck that originally qualified for the EPA 21-year exemption loses that exemption if the engine has been replaced with anything other than an equivalent or newer EPA-certified engine. If customs records show code “E” on the EPA form but the engine under the hood doesn’t match the original specifications, the import may have been fraudulent, and that liability follows the vehicle.

The third is assuming an out-of-state title is enough. Texas requires its own VIN inspection (Form VTR-68-A for vehicles last registered in another country) and its own safety inspection. An out-of-state title simplifies the ownership-evidence requirement but doesn’t eliminate the inspection steps.
