Commercial Plates vs Apportioned Plates

Every commercial vehicle on the road needs a license plate, but not all plates are the same. If you haul freight or run a service vehicle, you’ve probably heard terms like “commercial plates” and “apportioned plates” thrown around. The names sound similar, and it’s easy to get them mixed up.

Here’s the deal: using the wrong plate type isn’t just a small mistake, it can lead to fines, delays, and headaches at weigh stations or roadside inspections. On the flip side, choosing the right plate type can help you save money, avoid unnecessary paperwork, and keep your business compliant.

Let’s break it down so you can figure out exactly which type of plate fits your operation, without getting buried in government jargon.

What Are Commercial Plates?

First things first, it is vital to understand what Commercial plates are. They are the standard license plates issued to vehicles used for business purposes. In fact, they’re generally intended for intrastate operations, meaning the vehicle stays within one state for all work-related travel.

These plates are issued by your state’s Department of Motor Vehicles (DMV) or an equivalent agency. You’ll typically see commercial plates on local delivery vans, box trucks, and service vehicles that never cross state lines for business.

Example: If a plumbing company in Arizona has a work truck that only does service calls in Phoenix and Tucson, that truck will have Arizona commercial plates. No IRP registration is needed because it never leaves the state for business.

Commercial plates are simpler than apportioned plates, but they still come with requirements:

Vehicle registration: You must register the truck with the state DMV.
Inspections: Some states require periodic safety or emissions inspections.
Proof of insurance: You’ll usually need to show active coverage for business use.
Business use documentation: Proof that the vehicle is used for work purposes, not just personal driving.

The key thing to remember: commercial plates do not authorize interstate hauling. If you take a load across state lines with only commercial plates, you could be cited for operating without proper credentials.

What Are Apportioned Plates?

Apportioned plates are part of the International Registration Plan (IRP), a cooperative agreement among the U.S., Canada, and some Mexican states that allows commercial vehicles to operate across multiple jurisdictions using one license plate.

They’re designed for interstate or international operations. If your truck regularly or even occasionally crosses state lines for work, IRP plates may be required.

Examples of who needs apportioned plates:

A semi-truck hauling freight from Texas to California.
A regional carrier running loads from Illinois to Indiana and Michigan.
A trucking company delivering goods from New York to Ontario, Canada.

Apportioned plates are issued through your state’s IRP office (often a separate division from the regular DMV). The process is more involved than getting commercial plates, expect to provide detailed information on your operation, equipment, and expected routes.

One big difference is how fees are calculated. Under IRP, your registration costs are “apportioned” based on the percentage of miles you run in each state or province. That means a truck that spends 70% of its time in Texas and 30% in Louisiana will have fees split between those jurisdictions accordingly.

Apportioned plate holders must also:

Keep detailed mileage logs for every jurisdiction traveled.
Submit periodic trip reports.
Renew their IRP registration annually.

Key Differences Between Apportioned and Commercial Plates

Feature	Commercial Plates	Apportioned Plates (IRP)
Travel Scope	Intrastate only (within one state)	across states/provinces
Who Needs It	Local businesses, service vehicles, in-state deliveries	Long-haul truckers, carriers operating in multiple states
Registration System	State DMV or local licensing office	International Registration Plan (IRP)
Fee Structure	Flat fee set by the state	Fees apportioned by distance traveled in each jurisdiction
Vehicle Weight Limit	Any commercial vehicle within the state	Usually over 26,000 lbs or with 3+ axles crossing state lines
Paperwork & Reporting	Minimal	Requires mileage tracking, trip reports, annual renewals
License Plate	Regular state-issued commercial plate	One IRP plate valid across all IRP member states/provinces
Compliance Risk	Risk of fines if used for interstate hauling without IRP	Must maintain mileage records to stay compliant

Choosing the Right Plate for Your Operation

If you only operate in one state and your truck never crosses the border for work, commercial plates are the most affordable and least complicated option. They’re especially practical for small service companies, local delivery routes, and contractors who stick to a home base.

But if your business model involves crossing into another state, even just once in a while, apportioned plates may be required. For example, if you run mostly local deliveries but occasionally take a load into a neighboring state, you can’t legally do that with only commercial plates.

It’s also worth noting that if your truck meets certain weight or axle criteria (generally over 26,000 pounds or 3+ axles) and crosses state lines, you must have IRP registration. This applies whether you’re running one truck or a whole fleet.

Getting Help With IRP Registration

The IRP process can feel like a maze, especially if you’re new to trucking or running your own authority. There are mileage calculations, reporting requirements, and deadlines to track, all while you’re trying to keep your truck on the road making money.

That’s why many owner-operators and small carriers choose to work with third-party registration specialists. These professionals can:

Handle the paperwork for new IRP accounts.
File renewals on time.
Keep your records in order for potential audits.
