If you are a truck driver, owner-operator, dispatcher, or fleet manager, understanding freight types is an important part of running a successful trucking operation. Not every load can be hauled with the same trailer, and not every shipment has the same handling, equipment, scheduling, or documentation requirements.
So, what are the different types of freight?
Freight can be categorized in several ways, including by the type of trailer or equipment required, how much cargo is being shipped, how the freight must be handled, and whether it has special transportation requirements.
Common examples include dry van freight, refrigerated freight, flatbed freight, bulk freight, LTL, FTL, hazardous materials, oversized loads, and time-sensitive shipments.
For carriers and dispatchers, knowing these differences makes it easier to match the right truck with the right load. It can also help drivers understand what to expect before accepting a shipment.
What Is Freight?
Freight is goods or cargo transported from one location to another for commercial purposes.
A shipment could contain consumer products, construction materials, machinery, food, industrial equipment, packaged goods, raw materials, or many other products.
In trucking, freight is commonly moved using equipment such as:
- Dry van trailers
- Refrigerated trailers
- Flatbed trailers
- Step deck trailers
- Lowboy trailers
- Tankers
- Dump trailers
- Specialized trailers
The equipment depends on the cargo.
For example, boxed consumer products may fit well in a dry van, while fresh produce may require temperature-controlled transportation. Large construction equipment may need a flatbed, step deck, or specialized trailer.
This is why freight knowledge matters before a load is booked.
What Are the Different Types of Freight?
There is no single system that describes every shipment in exactly the same way. Freight can be grouped by equipment, shipment size, cargo characteristics, handling requirements, and transportation needs.
For trucking professionals, the following categories are among the most useful to understand.
1. Dry Van Freight
Dry van freight is one of the most common types of truck freight in the United States.
A dry van trailer is an enclosed trailer designed to protect cargo from weather and normal road conditions.
Typical dry van freight includes:
- Packaged food
- Clothing
- Furniture
- Consumer products
- Electronics
- Paper products
- Retail merchandise
- Non-perishable goods
Dry van loads are often palletized or packaged, making them suitable for loading at distribution centers, warehouses, and manufacturing facilities.
What should drivers know?
Before accepting a dry van load, drivers and dispatchers should review the:
- Weight
- Number of pallets
- Pickup and delivery appointments
- Commodity
- Loading requirements
- Trailer condition requirements
- Special facility instructions
The freight may be enclosed, but the load still needs to be secured and handled appropriately.
2. Refrigerated or Reefer Freight
Refrigerated freight, commonly called reefer freight, requires temperature-controlled transportation.
This type of freight may include:
- Fresh produce
- Frozen foods
- Meat
- Dairy products
- Pharmaceuticals and other temperature-sensitive products
- Other products requiring controlled temperatures
A reefer trailer uses a refrigeration unit to maintain a specified temperature range.
Temperature requirements can vary significantly by product and shipper. Drivers should never assume that every reefer load uses the same setting.
Before pickup, confirm the required temperature, operating instructions, fuel requirements for the refrigeration unit, and any shipper-specific procedures.
Why reefer freight requires extra attention
Reefer operations involve more than simply driving the truck.
The driver may need to monitor:
- Temperature
- Refrigeration unit operation
- Fuel level for the reefer unit
- Pickup and delivery timing
- Washout requirements
- Product-specific instructions
The exact requirements should always come from the shipper, broker, carrier, or load documentation.
3. Flatbed Freight
Flatbed freight is transported on an open trailer without the enclosed walls found on a dry van.
Flatbeds are commonly used for cargo that is too large, too long, too tall, or otherwise unsuitable for an enclosed trailer.
Examples include:
- Steel
- Lumber
- Construction materials
- Pipes
- Industrial equipment
- Building materials
- Machinery
Flatbed loads often require careful cargo securement and may involve tarping, chains, straps, or other equipment depending on the cargo.
Drivers handling flatbed freight need to understand the carrier’s securement procedures and applicable regulations.
Because the cargo is exposed to the elements, weather can also be an important consideration.
4. Step Deck Freight
A step deck trailer has a lower deck height than a traditional flatbed.
This design can help transport taller cargo while keeping the overall loaded height within applicable limits.
Common step deck freight includes:
- Construction equipment
- Machinery
- Agricultural equipment
- Industrial components
- Large fabricated materials
The exact dimensions and weight of the shipment are important before booking.
A dispatcher should confirm the cargo dimensions rather than relying only on a general description such as “machinery.”
5. Lowboy and Specialized Heavy-Haul Freight
Lowboy trailers are designed to carry heavy or tall equipment while keeping the cargo closer to the road surface.
They may be used for equipment such as:
- Excavators
- Bulldozers
- Large construction machinery
- Industrial equipment
- Heavy agricultural equipment
Heavy-haul freight can involve additional planning because dimensions, axle weights, routing, permits, escorts, and other requirements may apply depending on the shipment and jurisdiction.
Carriers should verify applicable requirements before accepting this type of load.
6. Bulk Freight
Bulk freight is generally transported in large quantities without being packaged as individual boxes or pallets.
Examples include:
- Grain
- Sand
- Cement
- Chemicals
- Liquid products
- Agricultural materials
Different bulk commodities require different equipment.
For example, liquid products may require a tanker, while dry bulk materials may use specialized trailers designed for that commodity.
Drivers should understand what the trailer is designed to carry and follow all loading, unloading, cleaning, and safety procedures.
7. Full Truckload (FTL) Freight
FTL, or full truckload freight, generally means a shipment uses the available capacity of a truck or is moved as a dedicated truckload.
An FTL shipment typically moves directly between the shipper and receiver without being combined with unrelated shipments in the same way as LTL freight.
FTL can be useful when a shipper has enough cargo to justify dedicated truck capacity or when the shipment needs a direct movement.
For carriers, FTL loads can provide a straightforward operating plan, but the actual economics still depend on the rate, mileage, fuel costs, deadhead, time, and other operating factors.
8. Less-Than-Truckload (LTL) Freight
LTL, or less-than-truckload freight, involves shipments that do not require an entire truck.
Multiple customers’ shipments may be transported on the same truck or through a broader freight network.
LTL freight is common for businesses that need to move smaller quantities without booking an entire truck.
LTL transportation can involve:
- Multiple pickups
- Multiple deliveries
- Freight terminals
- Palletized shipments
- Detailed shipment documentation
For drivers and carriers operating in LTL networks, route planning and handling multiple shipments require a different workflow from a single-stop FTL load.
9. Hazardous Materials Freight
Hazardous materials, commonly called hazmat, require special attention because certain materials can create risks during transportation.
Examples can include certain:
- Chemicals
- Fuels
- Industrial products
- Compressed gases
- Flammable materials
Not every hazardous material requires the same handling or transportation process.
Hazmat transportation can involve specific requirements related to classification, packaging, labeling, documentation, training, placarding, and vehicle operation.
Carriers and drivers should verify the applicable federal and state requirements before accepting a hazmat shipment.
10. Oversized and Specialized Freight
Some cargo cannot be transported using standard equipment or standard dimensions.
Oversized freight may include:
- Large machinery
- Industrial components
- Construction equipment
- Structural materials
- Large tanks
- Specialized manufacturing equipment
These loads require careful planning.
Before dispatching an oversized shipment, confirm the cargo’s:
- Length
- Width
- Height
- Weight
- Loading method
- Unloading method
- Route
- Permit requirements
A load that appears simple from the commodity description can become complicated once its exact dimensions are known.
11. Expedited and Time-Sensitive Freight
Some freight needs to reach its destination within a specific or shortened time window.
Examples may include:
- Emergency replacement parts
- Manufacturing components
- Certain medical supplies
- Time-sensitive retail products
- Production-critical materials
Expedited freight requires close attention to appointment times and transit planning.
The dispatcher and driver need accurate pickup and delivery information before committing to the load.
The key question is not simply whether the truck can physically travel the distance. It is whether the entire schedule is realistic under the applicable operating requirements.
How to Choose the Right Freight for a Truck
Knowing the different types of freight is only the first step. Carriers also need to determine whether a specific load is appropriate for their equipment and operation.
Before booking freight, review these factors:
1. Equipment
Does the truck have the correct trailer?
A dry van, reefer, flatbed, tanker, and specialized trailer cannot automatically substitute for one another.
2. Weight
Check the shipment weight and make sure it fits the truck and trailer’s legal and operational limits.
3. Dimensions
For flatbed and specialized freight, confirm the exact dimensions.
4. Loading and Unloading
Find out whether the driver will live-load, drop-and-hook, or handle another loading process.
5. Schedule
Review pickup and delivery appointments carefully.
6. Route
Consider the complete route, including potential restrictions and the truck’s next destination.
7. Revenue and Operating Costs
Look at the complete trip rather than only the advertised gross rate.
Practical Example: Matching Freight to Equipment
Imagine an owner-operator has a 53-foot dry van.
A dispatcher finds two available loads.
Load A: Palletized retail products requiring a standard dry van.
Load B: Large pieces of construction equipment that require open-deck equipment.
Even if Load B appears to offer a higher rate, the dry van cannot simply be used because the freight requires different equipment.
Load A is the equipment-compatible option.
This basic example shows why freight selection begins with matching the shipment to the truck.
Common Freight Selection Mistakes
Understanding freight categories can help prevent several common mistakes.
Accepting a Load Without Checking Equipment
Always confirm the trailer requirements before booking.
Assuming All Freight Has the Same Handling Requirements
Food, machinery, chemicals, and general merchandise can have very different transportation requirements.
Ignoring Dimensions
Commodity descriptions are not enough for specialized freight. Get the actual dimensions.
Looking Only at Gross Revenue
Consider mileage, deadhead, time, fuel, tolls, and other relevant operating costs.
Failing to Confirm Appointment Details
A load that looks profitable may become difficult if the pickup or delivery schedule does not fit the truck’s available time.
Forgetting the Next Load
The delivery location matters because it affects where the truck can go next.
