Truck Permits

Managing truck permits correctly is a critical part of running a safe, compliant, and profitable trucking operation. Regulations change frequently at the city, county, state, and federal levels, and the consequences of an oversight can be costly: delays, fines, or even being taken off the road.

At Simplex Group, we have refined our methods over more than two decades of supporting carriers of all sizes. In this guide, we explain the main types of truck permits, the information you need to obtain them, the risks of managing everything in-house, and how our team, tools, and processes can simplify your daily operation.

What Is a Truck Permit and Why It Matters

A truck permit is an authorization issued by a government authority (city, county, state, or federal) allowing a commercial vehicle to operate under specific conditions that go beyond standard registration and licensing. In practice, permits are often required when a trip, vehicle, or load:

• Exceeds standard size or weight limits.
• Enters or crosses a state where the carrier is not apportioned or fully registered.
• Triggers specific fuel tax, routing, or local access requirements.

In other words, a truck permit confirms that your vehicle is allowed to be where it is, carrying what it carries, in the manner defined by the permit.

When a Truck Requires a Special Permit

You may need a truck permit in situations such as:

• Oversize loads: When the overall length, width, height, or overhang of the vehicle and load exceeds the legal limit in a given state.
• Overweight loads: When gross vehicle weight, axle weight, or axle group weight exceeds statutory limits.
• Temporary operations: When you are moving through a state where you are not permanently registered and require a temporary trip permit.
• Fuel tax requirements: When a qualifying vehicle enters an IFTA jurisdiction and requires a fuel permit because you do not have an IFTA license or decals in place.
• Local restrictions: When cities or counties require road use, access, or special use permits to protect infrastructure or manage congestion.

In practice, many carriers operate in multiple jurisdictions on a daily basis. Without a structured approach, it becomes extremely easy to miss a permit requirement.

Risks of Operating Without the Proper Permit

Operating without the correct permit is a compliance risk and a business risk. Common consequences include:

• Fines and penalties at roadside inspections or weigh stations.
• Out-of-service orders, forcing the truck and driver to wait until a permit is obtained or the load is adjusted.
• Route deviations imposed by enforcement, which may increase fuel cost and delivery times.
• Damage to customer relationships when deliveries are delayed due to administrative issues that could have been avoided.

From our experience, most serious permit issues do not occur because carriers ignore the rules, but because regulations change, each state handles permits differently, and internal teams are already overloaded. That is precisely the gap a structured permitting program is designed to close.

Main Types of Truck Permits in the United States

The term “truck permits” covers several different authorizations. Understanding each type is the first step toward staying compliant and protecting your operation.

Trip Permits

A trip permit is a temporary authorization that allows a commercial vehicle to travel in a state where it is not apportioned or registered under the International Registration Plan (IRP). You may need a trip permit when:

• You are running an occasional load into a state where you do not normally operate.
• You are moving a newly purchased truck that is not yet fully registered.
• Your IRP registration has lapsed and a temporary solution is required to complete a critical trip.

Trip permits are typically valid for a short period (often a few days) and specify which vehicle can operate, where, and for how long. When we support clients with trip permits, we focus on timing and route planning so that the authorization window matches the actual movement of the truck.

Fuel Permits and IFTA Compliance

Fuel permits relate to the International Fuel Tax Agreement (IFTA) and state fuel tax rules. A fuel permit is often required when a qualifying vehicle enters an IFTA jurisdiction without a valid IFTA license and decals.

This may happen, for example, when:

• A carrier runs occasional interstate loads and does not hold an IFTA license.
• A vehicle is newly acquired and the permanent credentials are not yet available.

Fuel permits are also temporary, and they ensure that the proper fuel tax obligations are met for the trip in question. Our role is to determine whether a fuel permit or full IFTA registration is more appropriate for your fleet profile and long-term plans.

Oversize and Overweight Permits for Special Loads

Oversize and overweight (OS/OW) permits are required when a vehicle and its load exceed the legal limits for weight and dimensions in a given state or on a specific route. These permits are highly specific:

• They may define the exact route you must follow.
• They may restrict travel to certain days or hours.
• They may require escorts or pilot cars for safety.

Because legal limits and permit rules vary by state(and sometimes by road or bridge) oversize and overweight permits are among the most complex to manage. Our permitting managers stay current with state and local requirements and help you avoid routes or times that would expose you to enforcement problems.

Local Permits

Beyond state-level permits, many cities and counties impose their own requirements. Examples include:

• Local overweight permits for specific roads or industrial zones.
• Access permits for restricted downtown or port areas.
• Construction or special event permits when infrastructure is temporarily affected.

We often see carriers underestimate the impact of city and county rules. That is why we position ourselves as the go-to experts not only for state permits, but also for the county and city authorizations that can disrupt a route if they are not addressed in advance.

Basic Requirements and Information Needed to Apply for Truck Permits

Truck permits cannot be issued without accurate and complete information. Investing time in organizing this data pays off in faster processing and fewer errors.

Vehicle Data

Authorities typically request detailed vehicle information, such as:

• Legal name of the carrier and USDOT/MC number.
• Vehicle identification number (VIN), license plate, and unit number.
• Overall length, width, and height of the vehicle and load.
• Gross vehicle weight and axle or axle group weights.
• Axle spacing and configuration.

When we onboard a new client, we capture this information carefully and store it securely. Once it is in our system, future permit requests are significantly faster because we no longer need to collect the same data for each order.

Route Information and Interstate Considerations

Permits are often route-specific. Authorities may ask for:

• Point of origin and final destination.
• Planned route, including highways and key junctions.
• States, counties, and cities to be crossed.
• Dates and, in some cases, times of day for the move.

Interstate operations add complexity because each state has its own rules. Our team takes into account:

• Which states require trip permits.
• Where fuel permits or IFTA considerations apply.
• Where size or weight restrictions force alternate routing.

By centralizing this information, we help clients avoid fragmented planning where each state is considered in isolation.

Typical Processing Times by Permit Type

Processing times vary widely by jurisdiction and permit type. As a general orientation:

• Trip and fuel permits are often issued relatively quickly, sometimes within hours.
• Oversize and overweight permits may take longer, especially if route analysis is required.
• Certain city or county permits can add extra time when local engineering or infrastructure teams are involved.

We do not control government processing times, but we can control how accurately and quickly we submit complete applications. Our permitting managers monitor regulatory changes and typical response times, so we can advise clients on realistic timelines and sequence their loads accordingly.

Common Challenges When Managing Truck Permits In-House

Some carriers choose to handle all permits internally. While this can work at a small scale, it introduces several challenges as the operation grows.

Constantly Changing Regulations Across States

Truck permit requirements are not static. States update:

• Size and weight limits.
• Seasonal restrictions, such as frost laws and spring thaw periods.
• Escort and signage requirements.
• Application processes and fees.

Keeping up with these changes in addition to everyday dispatch, safety, and customer issues can be overwhelming for internal staff. Our team is dedicated to this area; monitoring regulatory changes is part of our core responsibility, not an occasional task.

Delays, Detours, and Fines Due to Permit Issues

In our experience, many of the most expensive problems are avoidable. Typical issues include:

• Submitting incomplete or inaccurate information, causing permits to be delayed.
• Planning a route that is not approved for the permitted dimensions or weight.
• Forgetting a city or county requirement that applies within an otherwise compliant state-level route.

The result can be detention at weigh stations, forced detours, or even offloading and reconfiguring a shipment on short notice. These are operational disruptions that go far beyond the cost of the permit itself.

How Over Two Decades of Experience Change the Outcome

Over more than twenty years, we have seen most of the common problems—and we have built processes to prevent them. We assign each client a dedicated permitting manager who understands their fleet, routes, and recurring needs. This person becomes a central point of contact for all permit questions, rather than leaving each dispatcher to navigate regulations independently.

Clients can also visit one of our offices and sit down with an experienced permitting professional to discuss complex situations. This combination of experience, personal support, and structured processes significantly reduces errors and improves predictability in daily operations.

How Simplex Group Supports Your Truck Permit Needs

Our objective is not only to keep you compliant, but also to make permits as straightforward and predictable as possible.

Your Dedicated Permitting Manager

When you work with Simplex Group, you are assigned a dedicated permitting manager. This professional:

• Learns the specifics of your equipment, lanes, and freight profile.
• Coordinates all permit requests on your behalf.
• Advises you on timing, sequencing, and potential risks for upcoming loads.

Having a dedicated contact means you are not starting from zero with each order. Over time, your permitting manager becomes familiar with your patterns and can proactively suggest improvements to your permitting strategy.

Local Offices and In-Person Support

While many processes are now digital, there is still significant value in being able to speak with someone in person. You can visit one of our offices to:

• Review complex or unusual loads.
• Discuss long-term changes in your operation and how they affect permits.
• Train internal staff on basic permit concepts and best practices.

This in-person support builds trust and ensures we fully understand the reality of your operation, not just what appears in forms and systems.

Comprehensive Coverage: City, County, and State Permits

Our team handles:

• State-level trip, fuel, and oversize/overweight permits.
• City and county permits where local rules apply.
• Coordination with evolving interstate regulations and special requirements.

In practical terms, we aim to be the single point of contact for all the truck permits you will ever need, so you do not have to manage different processes and contacts for each jurisdiction.

SimplexHub and Simplex2Go: Requesting Truck Permits Online and On the Road

Technology is central to making permits easier to handle. For that reason, we offer both a client portal and a mobile application designed specifically for trucking operations.

How the SimplexHub Client Portal Works

Through our SimplexHub Client Portal, you can:

• Submit new permit requests online at any time.
• Provide trip details, vehicle information, and load data in a structured way.
• Track the status of permit orders.

Once you place your first order, we store your key information securely. For subsequent requests, you only need to provide the trip-specific details, dramatically reducing the time required to request permits.

Using the Simplex2Go Mobile App from the Cab

Our Simplex2Go Mobile App makes it possible for drivers or dispatchers on the move to:

• Request permits directly from a mobile device.
• Check status updates without being in the office.
• Access relevant permit information while on the road.

This flexibility ensures that critical permit needs do not have to wait until someone is back at a desk. It also reduces miscommunication between drivers and office staff.

Saving Your Information for Faster Future Requests

Both our portal and our app are built around the idea of not asking for the same information twice. After your first interaction, we save:

• Vehicle and fleet data.
• Common lanes and points of origin/destination.
• Contact details and preferred communication methods.

By reusing this information intelligently, we make future permit requests significantly faster and more consistent.

Going Beyond Compliance

Compliance is essential, but it is only the starting point. A mature approach to truck permits considers how permits affect the overall efficiency of your operation.

Planning Routes with Permit Requirements in Mind

Effective route planning takes into account:

• Which roads are approved for specific weights and dimensions.
• When certain routes or structures are restricted due to construction or seasonal rules.
• How to group loads or sequence trips to reduce the total number of permits needed.

We work with clients to design routes that are not only compliant, but also realistic and cost-effective. This may involve recommending alternate routes that reduce the risk of enforcement issues or combining permit planning with dispatch decisions.

Reducing Downtime and Roadside Risk

Permits directly influence:

• How often your trucks are stopped for inspection.
• The likelihood that a stop will result in a fine or delay.
• The amount of time your assets spend waiting instead of moving freight.

By ensuring that the right permits are in place, aligned with the correct routes and schedules, we help minimize unplanned downtime. This protects your revenue, your customer relationships, and your safety record.

Measuring the Impact on Your Operation

An optimized permitting process can be measured in terms of:

• Fewer enforcement issues and fines.
• Reduced administrative time spent on rework and corrections.
• More predictable transit times and better on-time performance.
