The Ultimate Guide to Oversize Load Permits in Flatbed Trucking

Flatbed trucking is a seriously cool process, honestly, but trucking oversize and overweight loads is the most profitable aspect of the business, despite being strictly regulated. These super machines are used in moving big projects like construction equipment and wind turbine blades or huge industrial machinery.

However, with all of the big items that you can load up in a truck, there are some serious federal and state regulations that govern how and where you can transport these heavy items, as well as the necessary permits to do so, legally. Failure to obtain a permit or violating a route specification can result in sizable fines, loss of time or even the loss of operating authority.

Dexter Dispatch Services is really just your go-to answer to sorting out all those permit headaches, route plans, and compliance stuff so yeah, whatever just focus on driving and putting the pedal to the floor and making bank with all that walking money.

I’ll discuss the complete need to know about oversize load permits in general including the definition, requirements, side effects and methods to get by, and the ramifications if you proceed discouraged.

What Is Considered an Oversize Load?

An oversize load is generally any vehicle or combination of vehicles that exceed the federal or state law dimensions or weight laws.

Standard Federal Limits

Width: 8 feet 6 inches (102 inches)

Height: 13 feet 6 inches

Length: 48–53 feet (standard trailers)

Gross Weight: 80,000 pounds (combined total of truck, trailer, and cargo)

We are referring to a limit here – if your flatbed vector pushes you over it, only on one side, you are called oversize or overweight, and you will need to get a permit just to be able to drive.

Common Examples of Oversize Loads

• Construction machinery like cranes, excavators, or bulldozers
• Wind turbine components and blades
• Steel beams, industrial pipes, or bridge girders
• Prefabricated buildings or large containers
• Farming and mining equipment

Each state defines “oversize” slightly differently, which means permits are state-specific — one for each jurisdiction you travel through.

Why Are Oversize Load Permits Required?

The goal of oversize load permits is simple – safety and infrastructure protection.

Oversize loads can be a cause of serious road hazards if not handled correctly. Permits ensure that:

• The route can manage the truck weight and dimension

• Bridges and tunnels are high or sufficiently strong

• Minimal interference in traffic is encountered

• The public and driver are not in danger during transport

Without the proper permits, your load may cause cards to be damaged, endanger other motorists or attract heavy fines.

How to Obtain Oversize Load Permits

Securing a permit may seem like the equivalent of undertaking a major project, although in reality, it isn’tucture, especially if you get connected with a dispatch service such as Dexter Dispatch Services.

Step 1: Measure Your Load Accurately

The first one is get the exact width, height, and the length of your truck and your trailer. Do not skip this part as it can screw up your entire route or can lead to your permit not being approved by skipping the step so inspecting these numbers is a must.

Step 2: Identify the States You’ll Cross

Each state has its own permit office and thus you would require a separate permit for each state that your route traverses. Basically, plan out your journey and plan the permits accordingly.

Step 3: Apply for Permits

Most states have cut this process using their DOT (Department of Transportation) portal. You will have to scroll and fill in the following:

• Truck and trailer details

• width between axles, kilograms per axle;

• Load type and description

• Route and travel dates of preference

Step 4: Wait for Approval

Approval takes varying amounts of time, which can be a few hours or a few days depending on the complexity of the route and the workdays, or lack thereof, of the state’s docket. With this in mind, don’t put yourself in a rush and apply early.

Step 5: Carry Your Permit

When you get the green light, print out your permit, and keep it in the cab. Officers can pull it at any checkpoint so it is best to have it ready to avoid any last minute hassle.

Types of Oversize Load Permits

They’re basically for one certain trip. Covers one route, one load and a set of travel dates. Essentially, transport only occasionally if it is going to be oversized.

2. Annual or Blanket Permits

These will allow you to make repeated trips with the same loads or routes in a year. Perfect for carriers that ship oversize freight a lot Decreases time and reduces paperwork.

3. Superload Permits

These are used when load is as big or heavier than regular limits. They will often require police escorts, engineering reviews and special route approvals.

Escort Vehicles and Pilot Cars

n many cases, escort vehicles (also called pilot cars) are required to accompany oversize trucks.

Purpose of Escort Vehicles

• Warn other drivers of wide or slow-moving loads
• Help navigate sharp turns, narrow bridges, or low-clearance roads
• Communicate hazards or road changes to the driver
• Improve safety for everyone on the road

• Load dimensions
• State rules and terrain
• Whether travel is rural, urban, or interstate

At Dexter Dispatch, we help coordinate required pilot cars to ensure your route stays compliant from start to finish.

Btw, invoicing is not possible for all roads or times for oversize vehicles. Travel restrictions are also implemented by states to ensure safety and as well as low traffic.

Common Restrictions

• Daylight only passage (sunlight before 30 minutes to 30 minutes after sunset).

• No travelling on Sundays or holidays.

• Zoning restrictions for big cities (e.g. labor-hour restrictions)

• Weather limitations (no travel in fog, snow or heavy rain)

Encompassing these limitations means you could get into trouble for breaking the law and therefore end up losing your permit or are fined.

Before you hit the road, route planning is critical for safety and compliance.

Things to Check

• Bridge height and clearance
