It’s one of the most common questions in the transportation industry: The length of time it will take to transport freight from Point A to Point B.
The answer is that it depends — and yes, we can hear your groaning from here!
It’s not the answer any shipper wants, but it’s the truth. When dealing with so many variables — origin location, destination location, weather, and traffic, just to name a few — it’s hard to give a firm answer.
But many people aren’t aware of one of the biggest, most critical variables at play in this equation: truck driver Hours of Service (HOS).
Truck drivers have a limited number of hours they can spend behind the wheel each day, which can be a major factor in total transit time. But the rules regarding HOS can be tricky to understand.
That’s where we come in!
The Anderson Trucking Service (ATS) team has decades of experience in the trucking industry, so we understand that safe, legal driving practices are of the utmost importance — and that includes understanding and abiding by driver HOS regulations.
Read on to discover the factors that impact daily miles, how shippers can increase daily distance, and estimates of how far a driver is allowed to drive in one day.
Truck drivers are allowed to drive a maximum of 11 hours in one day.
With that said, there are several other regulations and limits that factor into the number of hours a driver can be behind the wheel.
The Federal Motor Carrier Safety Administration (FMCSA) set truck driver Hours of Service (HOS) regulations, which all U.S. truckers must follow.
These limits are the single most important factor that determines how many miles a driver can travel in one day. They include:
Drivers use electronic logging devices (ELDs) to track the amount of time they spend driving each day. Responsible drivers take these limits seriously and do not try to break any of these safety regulations.
And finally, a little myth-busting: Drivers are not limited by the number of miles they can drive per day — but we'll talk about mileage next anyway!

Truckers aren't legally limited to a certain number of miles driven per day, but on average, the typical truck driver can travel about 500 miles per day.
This number is a reflection of drivers' maximum hours behind the wheel, average speeds, and other variables.
As we've already established, a driver can spend a maximum of 11 hours per day driving. Where speed is concerned, many trucking companies rely on “governors” which cap the driver’s speed at 65 miles per hour (mph).
If a driver traveled at 65 mph for their full 11-hour daily driving maximum, they’d cover 715 miles that day. (To put that into perspective, the entire state of Montana is 630 miles wide.)
But that isn't a realistic scenario — drivers simply do not travel totally empty interstates at a steady 65 mph for 11 hours straight. (They can't — they have to take a break after 8 consecutive hours of driving, anyway!)
With that in mind, let's find our way to more reasonable averages. After factoring in the speed limit variability of the roads in towns and cities, stopping-points like traffic lights or stop signs, and the all-import traffic report, the average speed for truckers is more like 50 mph.
The time attributed to other driver job duties also influence the number of miles a trucker can travel in a day. Within their daily 14-hour on-duty window, truckers have many non-driving duties to accomplish, including:

Drivers aren't typically paid for these tasks (most drivers are paid by the mile), but they still eat into their driving time for the day.
So, after accounting for the time invested in non-driving tasks, we've found most drivers can drive about 500 miles per day.
Truck drivers' progress can be delayed by any number of circumstances that burn up their daily allotted HOS, including weather, road construction, empty miles ("deadheading"), geography, and oversize travel limitations.
If you’ve been in (or worked with) the transportation industry for any amount of time, you know that things don’t always go as planned.
There are circumstances beyond essential non-driving tasks — and beyond a driver’s control — that can make it difficult or downright impossible to travel 500 miles per day.
These considerations can translate to longer transit times, but an experienced transportation provider should be able to anticipate some of these elements and build them into your timeline.
A driver’s 11- and 14-hour limits include all their time behind the wheel, regardless of whether they’re hauling freight.
That means that if a driver has to travel with an empty trailer (colloquially called "deadheading") to get to your location, those miles are adding to their HOS clock without getting your freight any closer to its destination.
As a shipper, here are some ways you can help prevent or mitigate the impact of deadheading:
Overnighting onsite allows your driver to to start their HOS clock at your location (rather than at their domicile or a truck stop offsite), leaving them plenty of time to load your freight without burning hours.
Weather is the ultimate uncontrollable variable. Inclement weather can come on without warning and delay a trucker's travel for minutes, hours, or days.
Many shippers don't consider the reality of weather's ripple effect. It may be 70 degrees and sunny in your location, but your shipments can still be impacted by the wintery weather your driver encountered earlier in their travels.
Icy and snowy roads will cause a driver to drive more slowly (or even stop) for their own safety, that of their freight, and that of the general motoring public.
Ultimately, there’s no way to skirt the impact of weather delays (unless you have a direct line to Mother Nature), so it’s best to simply keep an eye on the relevant forecasts and give your drivers a bit of grace.
Just like sitting in traffic, time spent waiting for road construction counts as "driving" — without making much progress toward a destination.
In areas that experience seasonal weather changes (i.e. the Midwest and northeast), road construction comes in with the spring thaw and goes out with the first frost.
Summer months are therefore the most common time for drivers to be delayed by construction and detours in these regions; in areas that experience mild, warm weather year-round, the prevalence of road construction will depend more on local projects and their timelines.
If you’d like to help mitigate delays in the final stretch of your driver’s journey, remember that most drivers won’t be local to your area and will therefore not be aware of road closures or detours due to construction. Be sure to communicate any major road construction projects in your area to your transportation provider.
They’ll be able to check your tips against your driver’s route and help them plan accordingly, which can ultimately help the driver save time.
In some parts of the country, freight can travel more quickly than in other areas.
Typically, drivers encounter more traffic when traveling through or near large cities, which translates to slower travel. Drivers will try to avoid cities during regular commuter hours, but sometimes those delays just have to be endured.
And here’s an interesting fact: Freight traveling in the eastern part of the U.S. is less likely to travel at a steady 50 mph.
This is because older infrastructure, more compact roads, and greater population density mean more stopping and starting, which results in fewer opportunities to get up to speed.
In the western part of the country, it’s a different story. Newer, wider roads, fewer drivers, and more space between cities means a driver may exceed the 500-mile-a-day average.
It’s important to note that these limits apply to legal freight. Over-dimensional (OD) loads will travel more slowly in nearly all circumstances.
Permitted freight has extra restrictions and regulations around its movement, which means it often travels slower than legal freight.
Some factors that can impact oversize freight are:
No matter the size of your freight, it’s important to work with your transportation carrier to understand the estimated timing of your haul. They may also be able to make suggestions to help your freight travel more quickly and smoothly.
If a critical load absolutely needs to travel more than 500 miles in one day, the most effective solution is team drivers.
As the name implies, “team drivers” are two Class-A CDL-licensed drivers who work together, alternating their shifts behind the wheel to keep the truck moving during required breaks.
It’s important to note that team drivers still have rest periods when the truck isn’t moving. But that’s still twice as much drive time in a day, which can get you freight that much further along in its journey — at least under ideal circumstances.
Of course, an extra driver amounts to extra costs. Expect to pay 30 to 40 percent more for a team driver load.
While it’s true that team drivers are the only way to achieve 1,000 miles in a day, there are some smaller ways to help your driver maximize their allowed drive time.
The more time a driver can spend on the road, the faster your cargo will move.
As a shipper, you have an opportunity to help set drivers up for a smooth, successful run. By taking a few proactive steps in advance of any freight movement, you can facilitate a more seamless experience for all involved:
No matter how far your freight needs to travel, understanding the factors that influence transit times can help you set realistic expectations and make informed decisions.
From truck driver Hours of Service regulations to road conditions, geography, and shipper-driven efficiencies, many variables impact how quickly freight moves. By preparing ahead of time, staying flexible, and maintaining open communication with your carrier, you can help minimize delays and keep your shipments on track.
Of course, choosing an experienced, reliable transportation provider can help you get the most bang for your buck.
