What Is a Kei Truck? The Complete UK Guide (2026)

Q: Does the US 25-year rule apply in the UK?

No. The UK threshold is 10 years from first registration. Anything older imports on a simple MOT; the 25-year rule is US-only.

A kei truck is a tiny Japanese pickup — 660cc, under 3.4 metres long, and good for a 350 kg payload — built to Japan's "kei" light-vehicle rules. Small engine, tiny footprint, honest workhorse. Cheap to buy, capable in 4WD, and characterful in a way nothing else on UK roads is.

This is the beginner's overview: what kei actually means, why Japan built them, who makes them, what they're like to own, and — the bit most UK buyers want — exactly how you get one road-legal here. Each section links out to our detailed model guides.

The short version: A kei truck is a 660cc, ~3.4 m, 350 kg-payload Japanese mini truck. Happiest at 45–55 mph, surprisingly capable in 4WD, and 40–55 mpg. In the UK, any one over 10 years old imports on a simple MOT (the US "25-year rule" doesn't apply here). The catches: they're slow on motorways, and pre-2006 examples aren't ULEZ-compliant.

What "kei" actually means

Kei (say "kay") is short for kei jidōsha (軽自動車) — "light automobile". It's a Japanese government class with strict limits; stay inside them and you pay less tax and insurance in Japan. The rules have been stable since 1998:

Limit	Maximum
Length	3.40 m
Width	1.48 m
Height	under 2.0 m
Engine	under 660cc
Power	64 PS (63 hp) — a voluntary industry cap

That's the whole brief every kei truck is built to. The 64 PS limit is a "gentleman's agreement" rather than a hard law, but every maker sticks to it.

Kei truck vs kei van vs kei car

Three things share the kei rules:

Kei truck (軽トラ, keitora): the cab-over flatbed pickup — driver above the front wheels, open bed behind, engine under the seat. 350 kg payload. This is what most people mean by "kei truck."
Kei van: the enclosed version — sliding side door, twin rear doors, same running gear. Increasingly converted into micro-campers.
Kei car: a normal little passenger car in the same size class (not our focus).

Why kei vehicles exist

Japan created the class in 1949 to get a war-recovering nation driving cheaply. The engine limit grew over the decades (150cc → 360cc → 550cc → 660cc in 1990), and the size limits were relaxed in 1998 to today's figures. In return for staying small, Japanese owners get lower tax, cheaper insurance, reduced tolls, and — crucially in cities — an exemption from the "prove you have a parking space" rule in many rural areas. The incentives are so effective that kei vehicles make up around a third of all new car sales in Japan, which is why there are millions of cheap, well-kept used ones to import.

The main makes and models

Four companies build almost all of them, and the rest are rebadges:

Suzuki Carry (truck) & Every (van) — Japan's best-seller and the most common in the UK. See the Carry DA63T, DA16T, Carry/Every Classic, Every DA64V and Every DA17V guides.
Daihatsu Hijet (truck) & Hijet Cargo/Atrai (van) — the best UK parts and dealer support of any kei. See the Hijet S201P, Hijet S200P/S500P and Hijet Cargo guides.
Honda Acty — the oddball with a mid-engine layout; built until 2021. Plus the modern N-VAN. See the Acty, N-VAN and Acty Van/Vamos guides.
Subaru Sambar — the other oddball, rear-engined and four-cylinder (the true Subaru ones, pre-2012). See the Sambar guide.
Mitsubishi Minicab — the value pick, with a turbo option. See the Minicab guide.

The rebadge web — useful to know for parts. Many badges are the same truck underneath: the Mazda Scrum and Nissan Clipper are rebadged Suzukis (or, for the older Clipper, a Mitsubishi); the Toyota Pixis and post-2012 Subaru Sambar are rebadged Daihatsu Hijets. Same vehicle, shared parts — but check the era, because the donor changed over time.

What they're actually like

Engine and speed. A 660cc three-cylinder (four on the old Subaru), 38–53 PS naturally aspirated or 58–64 PS turbo. Realistic top speed is around 65–70 mph (NA) or 75–85 mph (turbo), but they're happiest cruising 45–60 mph. The turbo versions are markedly better if you'll cover distance.

Payload and size. A flat 350 kg payload across the board — a pallet of materials, a few hay bales, a ride-on mower. The truck is ~3,395 mm long and 1,475 mm wide (shorter than a Mini, narrower than a Golf), with three drop-down bed sides.

4WD. The better-specified trucks have selectable 4WD, a Hi/Lo transfer (low range), and a rear diff lock — and on a sub-tonne vehicle that's genuinely capable on mud, wet grass and farm tracks. But these features are grade-specific (usually the manual), so you have to look for them.

Other bits: they're right-hand drive (same as the UK), do 40–55 mpg, turn within a garage, and read in kilometres (÷1.609 for miles).

Why people import them to the UK

Smallholdings and farms — a weatherproof, road-legal, higher-payload alternative to a quad.
Estates, grounds and gamekeeping — narrow enough for tight gates and gentle on turf.
Trades and small businesses — parks anywhere, 40+ mpg, cheap to insure.
Green-laning and overland — light and narrow, with real 4WD on the right spec.
Micro-campers — the kei van is a brilliant little camper base for two.

Cheap, capable, characterful, and it fits where bigger vehicles can't — that's the appeal.

Importing one to the UK

The single most important thing: the UK uses a 10-year rule, not the US 25-year rule.

Over 10 years old (from first Japanese registration): registers on a standard MOT — straightforward.
Under 10 years old: needs an IVA test (Individual Vehicle Approval) plus some modifications first — more cost and time.

The rest of the process: ship it over, submit a NOVA declaration to HMRC within 14 days, pass the MOT (fit a rear fog light first — JDM trucks don't have one), and register with the DVLA. We cover the whole thing in the import guide.

Tax and duty — check, don't assume. VAT is 20% on the landed value. Import duty is the moving part: from January 2026 the UK–Japan trade agreement zero-rated duty on many Japan-built cars, but a kei truck classed as a goods vehicle may be treated differently and still attract duty. Confirm the commodity code with HMRC or a customs broker before you commit (or buy from a UK dealer who's handled it).

Road legality, speed limits and ULEZ

Once registered, a kei truck is fully road legal on a standard car (Category B) licence — no special test, no off-road restriction.

Speed limits. Registered as a light goods vehicle, it's subject to the lower goods-vehicle limits — typically 50 mph on single carriageways and 60 on dual carriageways (70 on motorways), rather than full car limits. In practice its comfortable cruising speed matters more than the legal number. Motorways are legal but best left to the turbo models.

ULEZ — the catch for London. Petrol vehicles need Euro 4 to avoid the daily charge, which broadly means registered from January 2006. So most 2006-onward kei trucks are compliant, but pre-2006 examples — and all the 1990s F6A classics — are not and pay £12.50/day in Greater London. Always confirm a specific vehicle on the TfL ULEZ checker once it has a UK plate.

Pros and cons — honest version

Pros	Cons
Cheap to buy (used from ~£3,000) and run (40–55 mpg)	Slow on motorways, especially the non-turbo ones
Tiny — fits gates, lanes and parking spaces	Older safety standards; usually no airbags
Genuine 4WD (Hi/Lo + diff lock on the right spec)	km speedo/odometer to get used to
Right-hand drive; standard car licence	Parts vary by model (Hijet/Carry easiest)
Simple and easy to work on	Pre-2006 examples aren't ULEZ-compliant
Loads of character	350 kg payload fills up faster than you'd think

Frequently asked questions

Are kei trucks road legal in the UK?

Yes — fully road legal once DVLA-registered (with an MOT, plus an IVA if it's under 10 years old). No special licence and no off-road-only restriction.

How fast does a kei truck go?

Around 65–70 mph naturally aspirated, 75–85 mph turbo — but they're happiest at 45–60 mph. Fine for A and B roads; turbo models cope with dual carriageways and short motorway stints.

How much do they cost?

Used examples start around £3,000–6,000 + VAT for a basic 2WD; £6,000–10,000 + VAT for a good 4WD with Hi/Lo and diff lock. New delivery-mileage imports from UK dealers are roughly £13,000–18,000 + VAT.

Does the US 25-year rule apply in the UK?

No. The UK threshold is 10 years from first registration. Anything older imports on a simple MOT; the 25-year rule is US-only.

Can you get an automatic?

Yes — most generations offered an auto. Watch two things: Suzuki's AGS (an automated manual on the current Every/Carry) has reliability niggles, and the current Hijet's CVT loses the 4WD low range and diff lock. For 4WD or heavy use, the manual is the one to have.

Are they reliable?

Modern ones (chain-driven K6A, R06A and KF engines) are very reliable with regular servicing. The main watch-points are the timing belt on 1990s F6A and Honda E07 engines (interference engines — belt history is critical) and Suzuki's AGS gearbox.

Do I need a special licence?

No — a standard UK Category B car licence covers any kei truck. They're all well under 3.5 tonnes.
