The load-to-truck ratio is the number of loads posted on a load board divided by the number of trucks posted, measured for a specific market and equipment type. It’s the fastest read available on freight supply and demand. When the ratio climbs, loads are outpacing available capacity and rates tend to follow. When it falls, trucks outnumber loads and rates soften.
Carriers, brokers, and shippers all watch this number, and they use it differently. Here’s how it works, what it can tell you, and where it falls short.
How to calculate the load-to-truck ratio
The math is simple:
Load posts ÷ truck posts = load-to-truck ratio
Say a market has 300 outbound van loads posted and 100 available vans posted. That’s a ratio of 3.0, or three loads for every truck.
The ratio rises when load posts go up, truck posts go down, or both happen at once. It falls when the opposite happens. DAT calculates ratios by market and by equipment type, so a single city can run tight for flatbeds and loose for vans in the same week.
Market-level ratios are normally calculated on outbound freight. A market with a high outbound ratio has more freight leaving than it has trucks available to haul it. National and equipment-type ratios are simply total loads divided by total trucks, where direction doesn’t apply.
What the load-to-truck ratio tells you
The ratio measures pressure. It’s closer to a barometer than a thermometer, and it’s relative. Is there more pressure in Chicago than in Dallas this week? Is there more pressure today than there was a month ago? The direction and the comparison matter more than the number by itself.
That’s the most useful way to read it. A ratio of 4.0 doesn’t mean much in isolation. A ratio that has climbed from 2.0 to 4.0 over three weeks tells you capacity is tightening and rates are likely moving up. A ratio that has fallen from 6.0 to 4.0 tells you the opposite, even though the number is identical.
Load-to-truck ratios also tend to move before rates do. Brokers and carriers feel the market shift on the board before it shows up in what loads actually pay. That lead time is the practical reason to track the ratio at all.
Load-to-truck ratios by equipment type
- Dry van. The broadest freight base and the steadiest ratios of the three. Van numbers move in the narrowest range, which makes them a useful baseline read on the market.
- Reefer. Seasonal and regional. Reefer ratios spike hard in produce-growing areas during harvest and settle back down after.
- Flatbed. The highest and most volatile ratios of the three. Flatbed demand tracks construction, manufacturing, and weather, and it slows in winter across much of the country.
Because the three behave so differently, DAT reports them separately. Comparing across equipment types tells you very little.
What counts as a good load-to-truck ratio?
You’ll see sources claim that two loads per truck is a healthy benchmark. Treat that with caution. A universal benchmark doesn’t hold up, because normal looks different depending on what you’re hauling, where you are, and when.
Equipment type is the first reason, and the ranges above show why. Flatbed ratios routinely run several times higher than van ratios, and that’s typical rather than a sign of a hot market. Judging a flatbed number against a van benchmark will lead you to the wrong conclusion.
Why a high ratio in one market isn’t high in another
Geography is the second reason, and it trips up more people than equipment type does.
Every market has its own baseline. Dense freight hubs move enormous volume and attract heavy truck posting, so their ratios tend to sit lower than what you’d see in a thinner market with less capacity competing for the same freight. A 2.5 in a major hub can mean capacity is genuinely tight. That same 2.5 somewhere that normally runs 6.0 means trucks are sitting.
So the number by itself doesn’t travel. Comparing raw ratios across markets is a common way to misread them.
The workaround is to compare a market against its own recent history and against the national average for that equipment type. That comparison tells you something. An absolute threshold doesn’t.
A metric built to compare markets directly
If you need to compare markets head to head rather than each against itself, that’s what DAT’s Market Conditions Index is for. MCI starts from the same posting and search activity, then normalizes posting and search behavior and factors in historical trends and seasonality, so a score in one market means the same thing as a score in another.
It also tells you which side of the transaction has leverage, covers van, reefer, and flatbed separately, and includes a seven-day forecast, which the raw ratio can’t give you. MCI is available in select Load Board and RateView subscriptions.
What the load-to-truck ratio doesn’t tell you
The ratio is useful, and it has real limits. Knowing them keeps you from over-reading it.
- It measures posted freight, not all freight. Most truckload transactions happen under contract, and that freight usually reaches a load board only when it falls out of a shipper’s routing guide. The ratio reflects the spot market. That’s still valuable, because spot is where pricing moves first, but it isn’t the whole market.
- Not every truck gets posted. Plenty of carriers work their lanes by phone or through established broker relationships and never post capacity. Available trucks are undercounted.
- The same load can appear more than once. Postings sometimes stay up after a load is covered, and brokers may re-post the same freight more than once. Load counts can run high relative to the freight actually available.
- It says nothing about direction. Two markets can show the same outbound ratio while trucks strongly prefer one destination over the other. Carriers willing to run the less popular direction can often ask for more.
- It isn’t a rate. The ratio signals pressure on rates. It doesn’t tell you what a lane pays. For that you need actual rate data built from real transactions.
Why the ratio works anyway
Those posting quirks look like they should ruin the metric. They don’t, and the reason is worth understanding, because it’s the whole case for treating the ratio as a barometer.
The distortions aren’t random. They move with the market.
A broker reposts a load because it hasn’t been covered yet. Yes, that inflates the load count. It’s also direct evidence that the freight is hard to move, which is exactly what you were trying to find out.
The truck side works the same way in reverse. Some carriers only post their trucks to the load board when they’ve exhausted other avenues, so a larger share of available capacity shows up as truck posts on the board in a loose market than in a tight one. When capacity is genuinely tight, fewer trucks bother to post, the denominator shrinks, and the ratio climbs.
Both distortions push in the same direction as the underlying market. Read the movement, not the absolute number.
How to use load-to-truck ratios
If you’re a carrier
Use the ratio to decide where to be, not just what to take. A market with a rising outbound ratio gives you more options and more room to negotiate, which means fewer empty miles and less time sitting.
Watch the ratio in the market you’re delivering into. If you’re headed somewhere with a falling ratio, line up your next load before you arrive. Check the ratio in nearby markets too, since repositioning 100 miles to a tighter market sometimes pays better than waiting where you are.
Pair the ratio with lane rate data before you commit. A tight market tells you to push on price. Rate history tells you how far to push.
If you’re a broker
The ratio tells you how hard a load will be to cover before you quote it. A high outbound ratio in the origin market means fewer trucks competing for your freight, so build that into your pricing and your timeline.
Rising ratios are also your early warning on margin. If capacity is tightening in a market where you have committed freight, you’ll want to start working carriers sooner and lean on the relationships you’ve built rather than the open board.
If you’re a shipper
The ratio helps you anticipate cost and capacity instead of reacting to it. When outbound ratios climb in the markets you ship from, spot costs tend to rise, and carriers have more reason to turn down contract freight that pays below what the spot market is offering. Watch your tender acceptance alongside the ratio. When ratios fall, you have more room to negotiate.
Watching ratios across your network also helps with timing. If you have flexibility on when freight moves, shifting volume away from a tightening market can save real money. Ratios by equipment type matter here as well, since your reefer freight and your van freight won’t face the same conditions.
Where to find current load-to-truck ratios
DAT publishes national load-to-truck ratios for van, reefer, and flatbed on Trendlines, updated weekly. Market-level ratios are available in DAT One and DAT iQ, alongside the rate data you need to act on what the ratio is telling you. If you want conditions scored so you can compare one market against another, that’s the Market Conditions Index.
Frequently asked questions
What does a load-to-truck ratio of 3.0 mean?
It means three loads are posted for every available truck posted in that market. Carriers have more freight to choose from than trucks are available to haul, which puts upward pressure on rates.
Does a high load-to-truck ratio mean rates will go up?
Usually, though not always and not immediately. The ratio signals pressure rather than guaranteeing a rate change. A sustained rise across several weeks is a stronger signal than a single-week spike.
Is a 2.5 load-to-truck ratio good?
It depends entirely on the market and the equipment type. A 2.5 can mean capacity is tight in a dense freight hub that normally runs low, and it can mean trucks are sitting in a market that normally runs 6.0. Compare a market against its own recent history, or use a normalized metric like DAT’s Market Conditions Index if you need to compare markets against each other.
Is the load-to-truck ratio the same as the truck-to-load ratio?
No, it’s the inverse. A load-to-truck ratio of 4.0 is the same market condition as a truck-to-load ratio of 0.25. DAT reports load-to-truck.
Why is the flatbed ratio higher than the van ratio?
Flatbed ratios run structurally higher, often several times the van ratio, and flatbed demand concentrates in specific industries and regions. High flatbed ratios are normal rather than a signal on their own. Compare flatbed to flatbed history, not to van.
What does it mean when a market is “tight” or “loose”?
A tight market has high load-to-truck ratios, limited available capacity, and rising rates. A loose market has low ratios, plenty of available trucks, and softening rates. Both are relative to what’s normal for that market, season, and equipment type.
How often do load-to-truck ratios change?
Constantly. Postings turn over throughout the day. DAT reports weekly averages on Trendlines to smooth out daily noise, and shows more current views inside its products.
