Pallets and Highway Speed: What a Kei Truck Can Actually Do
Will a standard pallet fit in the bed? Can it actually keep up on the highway? Real bed dimensions, real top speeds, and the import classification that changes the speed answer entirely.
Two questions come up constantly from buyers who are sizing up a kei truck against an actual job: will my pallets fit, and can I drive this thing on a real road. Both have real, specific answers, and the highway question in particular has a legal wrinkle that gets misunderstood constantly, including by people selling these trucks.
Will a pallet actually fit?
Here’s the real number: a typical kei truck bed measures roughly 70-75 inches long and 50-55 inches wide, depending on the model. A 1999 Daihatsu Hijet, for example, has a bed that’s 74.5 inches long and 55 inches wide.
A standard US pallet is 48x40 inches. Run the math: loaded sideways across a 55-inch-wide bed, a 48-inch pallet fits with about 7 inches to spare. Loaded the other way, lengthwise in a 74.5-inch bed with the 40-inch dimension across, you’ve got more room front-to-back but need to check the width clearance against the 40-inch side. Either way, it physically fits on most kei truck beds, but it’s a real fit, not a generous one. Tie-down points and drop-side hardware can eat into that margin.
Check at inspection
Before you assume a pallet fits, measure your specific truck’s bed width at its narrowest point (some beds taper slightly near the cab) and compare against your actual pallet’s footprint, including anything strapped to its sides. “Kei truck beds fit a pallet” is a reasonable rule of thumb, not a guarantee for every model and every pallet.
Don’t forget the weight, not just the footprint
Fitting is one problem. Weight is the other, and it’s the one people actually get wrong. Bed payload on most kei trucks is rated around 770 lb (350 kg) at full passenger capacity. A loaded pallet of dry goods can easily run anywhere from 400 lb to over 1,000 lb depending on what’s on it. It is entirely possible to have a pallet that fits the bed perfectly and still exceeds what the truck is rated to carry.
Walk away if…
Eyeballing a pallet load and assuming it’s fine because it “looks like it fits.” Weigh it, or get a documented weight from whoever loaded it, and check it against your specific truck’s payload rating before you drive off. The bed not buckling under the weight doesn’t mean you’re within a safe or legal limit.
Now the speed question — and the part that actually matters
This is where things get genuinely confused online, so let’s be precise about it.
Mechanically, most kei trucks can do 65-75 mph ungoverned. Some, like the Subaru Sambar, have been reported as high as 87 mph under the right conditions. The engines are small, but the trucks are light, and the gearing is built for it. So the raw mechanical answer to “can it hit highway speed” is yes, comfortably, for the vast majority of these trucks.
The legal answer is a completely different question, and it depends entirely on how the truck was imported.
If your kei truck was imported under the 25-year rule as a full motor vehicle — which is the path this entire site is built around, and the path that applies to every model and eligibility page here — it is registered through a state DMV like any other car, and the federal 25 mph speed cap does not apply to it. It can be driven at normal road speeds, subject to whatever your specific state says about kei trucks on controlled-access highways (some states do restrict this regardless of import classification, so check your state’s guidance before assuming).
If your kei truck was imported and classified as an off-road or low-speed vehicle — a separate, different import pathway that some sellers and importers use, particularly for trucks that don’t yet qualify under the 25-year rule — it is legally capped at 25 mph by federal regulation, regardless of what the engine is capable of. This truck is not meant for highway use, and altering the speed limiter to get around this classification creates real legal exposure.
Green flag
If you’re buying through the 25-year-rule import pathway, confirmed by checking the model’s eligibility page on this site against the actual build date, you are not buying a 25 mph vehicle. You’re buying a normally-registered motor vehicle with a genuinely capable mechanical top speed, subject only to your state’s specific road-use rules.
Check at inspection
Before buying, ask the seller or importer directly which classification path the specific truck went through — 25-year-rule full motor vehicle, or off-road/low-speed vehicle. This single question determines whether you’re getting a real road vehicle or a 25 mph-capped machine, and it is not always obvious from a listing alone.
The honest bottom line
For pallet work: most kei trucks fit a standard pallet, but check your specific model’s bed dimensions and your pallet’s actual weight before assuming. For highway speed: the engine is rarely the limiting factor — the import classification is. Know which one you’re buying before you buy it, not after.

Frequently Asked Questions
- Will a standard pallet fit in a kei truck bed?
- It depends on the model and the pallet orientation. A typical kei truck bed is around 70-75 inches long and 50-55 inches wide. A standard 48x40 inch pallet fits loaded sideways (across the bed width) on most models with a few inches to spare, but check your specific model's exact bed width before counting on it — it's close on some trucks, not generous.
- What is the top speed of a kei truck?
- Mechanically, most kei trucks are capable of 65-75 mph ungoverned, with some models like the Subaru Sambar reported as high as 87 mph under certain conditions. What you can legally drive depends entirely on how the truck is imported and registered, not just what the engine can do.
- Is it true that kei trucks are limited to 25 mph in the USA?
- Only for trucks imported and classified as off-road or low-speed vehicles, not for trucks imported under the 25-year rule as a full motor vehicle and registered normally through a state DMV. This is the single most confused fact in the kei truck import space — the 25 mph cap is a classification issue, not a universal kei truck speed limit.
- Can a kei truck drive on the highway?
- If it's imported under the 25-year rule and registered as a standard motor vehicle, generally yes, subject to your state's specific rules. Some states restrict kei trucks from controlled-access highways regardless of import classification, so check your state's guidance before assuming. If it's imported and classified as an off-road/low-speed vehicle, no — it's legally capped at 25 mph and not intended for highway use at all.
- How much can a kei truck actually carry on a pallet load?
- Bed payload is typically 770 lb (350 kg) at full passenger capacity. A loaded standard pallet of dry goods commonly weighs 400-1,000+ lb depending on contents, so check your specific pallet's weight against the truck's rated payload before loading — it's easy to physically fit a pallet that's actually too heavy.
