Is a Kei Truck Street Legal in Delaware?

Short answer

Yes. Delaware has no law aimed at Kei Trucks, and the DMV's import procedure only requires proof of federal safety compliance for imports under 25 years old. A Kei Truck with complete customs papers can be titled and registered once it passes the free DMV safety and emissions inspection. The emissions test is the step most likely to cause trouble on 1996 and newer trucks.

Key law
21 Del. C. §§ 2143 and 2151; DMV Import Vehicle Procedure

Yes, through the DMV's Import Vehicle Procedure, which draws its federal-safety line at 25 model years. Vehicles made within the last 25 model years must show they meet emissions rules and Federal Motor Vehicle Safety Standards (FMVSS), or that they are exempt, before Delaware will title them. A Kei Truck past that line does not need a compliance label or conversion letter.

Delaware has no statute or regulation about Kei Trucks in either direction. That leaves the ordinary rules: assemble the import file, pass the state inspection, insure the truck and register it. The procedure also notes that import files may be reviewed by a supervisor before a title is issued, so complete paperwork matters more here than speed.

Our 25-year rule guide explains how a truck's age is counted at import.

How do you get a Delaware title and plates for a Kei Truck?

The DMV's import page lists the file: an ownership document plus an attached English translation, US Customs and Border Protection (CBP) Forms 7501 and 3461 with a stamp, electronic signature or record in ACE (the agency's electronic filing system), a completed HS-7 safety declaration, a copy of the EPA Form 3520-1 emissions declaration filed at the port, proof of Delaware insurance, a bill of sale where it applies and photo ID. Form 3461 is easy to forget, so ask your customs broker for it at entry. Our importing guide covers each document.

  1. Pick the model year with the emissions lane in mind

    Delaware gives older gasoline vehicles an idle test with a gas cap check, and newer ones an on-board diagnostics (OBD II) test. A Japanese-market truck from 1996 or later may not have a US OBD II port, so ask the DMV how it will test your exact year before you buy.

  2. Collect the customs documents

    The DMV asks for CBP Forms 7501 and 3461, stamped by Customs or backed by an electronic signature or ACE record, plus the completed HS-7 and a copy of the EPA Form 3520-1 filed at the port.

  3. Translate the ownership papers

    Bring the Japanese export certificate or other ownership document, translated into English, your bill of sale and photo ID.

  4. Buy Delaware insurance

    The DMV wants proof of Delaware insurance on the truck itself, and policies from other states are not accepted for titling and registration.

  5. Take the truck to a DMV inspection lane

    The truck must pass the safety and emissions inspection. The DMV issues the title application, Form MV212, during that visit, and supervisors may review import files before titling.

Registration for a truck with a gross load weight of 5,000 pounds or less is $40 a year under 21 Del. C. § 2151. Delaware has no sales tax, but it collects a motor vehicle document fee on the purchase price, which works out to roughly $5.25 for every $100 above $500.

What does the Delaware inspection check?

Under 21 Del. C. § 2143, the DMV inspects a vehicle before registering it, and the DMV says vehicles being titled in Delaware for the first time usually go through the lane. The inspection is free and covers safety items such as tires, brakes and windows, plus an exhaust test and a fuel system leak test.

The safety half is straightforward for a truck in good order. Make sure every lamp works, the wipers clear the glass and the brakes pull straight; fresh Kei Truck brake parts and wiper blades are cheap compared with a second trip.

Will a Kei Truck pass Delaware's emissions test?

Model year decides the test: the DMV gives older gasoline vehicles an idle test with a gas cap check, and 1996 and newer ones an OBD II test that reads the truck's computer. Kei Trucks built for Japan in those years were not made to the US OBD II standard, and their diagnostic ports may not talk to a US scanner.

So the buying rule is simple: if you can live with an older truck, a pre-1996 model avoids the question. For anything newer, ask the DMV in writing how it will test a 1996-or-later truck without US OBD II before money changes hands. A recent tune-up kit helps an older engine at the tailpipe, and our maintenance guide lists what else to refresh.

What else should Delaware buyers know?

Delaware's liability minimum is 25/50/10, personal injury protection (PIP) is mandatory as well, and the DMV only accepts Delaware coverage for titling. No statute limits a registered Kei Truck to certain roads or speeds, so it follows the same traffic laws as any pickup.

Coastal air and winter road salt are hard on an old frame, so read the corrosion codes on the auction sheet and check the frame before you bid; our buying guide shows where to look. Neighboring states take very different approaches, so check the Kei Truck laws hub if you might move.

Frequently asked questions

Does Delaware require federal safety compliance for an imported Kei Truck?

Not once the truck is 25 model years old. The DMV's import procedure says vehicles made within the last 25 model years must show federal safety and emissions conformity, or an exemption, before titling. A Kei Truck past that line still needs its customs, HS-7 and EPA paperwork, but not a compliance label or conversion letter.

Will a Kei Truck pass Delaware's emissions test?

That depends mostly on model year. The DMV runs an idle test with a gas cap check on older gasoline vehicles and an OBD II test on 1996 and newer ones. Japanese-market trucks from 1996 on were not built with the US OBD II system, so ask the DMV in writing how it will test your truck before you commit to it.

What does it cost to register a Kei Truck in Delaware?

Registration for a truck with a gross load weight of 5,000 pounds or less is $40 a year under 21 Del. C. § 2151. Delaware has no sales tax, but it charges a motor vehicle document fee on the purchase price. The fee is $8 below $400 and $13.75 at $400 to $500, and it climbs $5.25 per extra $100 after that. The DMV inspection is free.

Are Delaware highways open to Kei Trucks?

Yes. Delaware has no road class or speed restriction written for Kei Trucks, so a registered truck follows the same traffic laws as any other. A 660 cc truck is happiest on local roads and state routes, and it will struggle to keep pace on the busiest highways, so plan routes with that in mind.

What insurance does Delaware require for a Kei Truck?

The DMV lists minimum liability of $25,000 for one person's injuries, $50,000 for two or more people and $10,000 for property damage. Delaware also requires personal injury protection. Proof must be Delaware coverage on the truck, and many carriers quote short Japanese chassis numbers only by phone.
