Interstate or Intrastate? How to Choose the Right Trucking Path

Starting a trucking career or expanding your freight operations comes with a lot of decision-making. Choosing between interstate and intrastate operations is one of the most important early steps. 

This choice affects your CDL type, the kind of freight you can haul, your legal responsibilities, and even the age at which you’re allowed to drive commercially. Knowing the difference is essential for staying compliant and running a successful business.

Defining Interstate and Intrastate Commerce

Interstate commerce involves transporting goods across state lines. That includes trips that begin and end in the same state but involve cargo linked to a broader supply chain beyond state borders.

On the other hand, intrastate commerce means your operations and cargo stay within one state, from origin to destination. If your truck doesn't leave state lines and the shipment is purely local, that’s considered intrastate.

For example, delivering freight from Ohio to Pennsylvania is an interstate job. But if you're hauling construction materials between two cities in Georgia without the load ever crossing state lines or being part of a national supply chain, you’re operating intrastate.

CDL Requirements: Interstate vs Intrastate

So, how does this affect your CDL? A lot more than you might think.

Drivers operating under an interstate CDL must meet stricter federal standards. You have to be at least 21 years old, maintain a valid medical certificate that meets FMCSA guidelines, and follow nationwide rules like Hours-of-Service, electronic logging, and drug testing programs. This type of CDL allows you to cross state borders legally and haul interstate freight, making it ideal for long-haul drivers, national carriers, and those working with freight brokers.

If your license is marked "intrastate only," you're limited to hauling within your home state. This restriction is often labeled with a “K” code and usually applies to drivers aged 18 to 20 or those who haven’t certified their medical status under federal rules.

While intrastate CDL drivers may not face the full scope of federal compliance, they’re still regulated by state-level safety, insurance, and licensing requirements. Each state sets its own rules, so you’ll want to check with your local DMV to stay compliant.

How to Switch from Intrastate to Interstate

Now, what if you start intrastate but want to expand? Changing from intrastate to interstate CDL status is common, especially as drivers gain experience or aim to take on larger contracts. The upgrade process is simple. You’ll need to be 21 or older, obtain a federal medical certificate, visit your DMV to remove the “K” restriction, and self-certify as a non-excepted interstate driver. With a few updates and fees, you’ll be ready to operate across state lines legally.

Understanding Operating Authority

A common question that arises here is whether you need both interstate and intrastate authority. In most cases, no, you don’t. If you're registered for interstate authority with the FMCSA, that typically covers you for in-state operations as well. 

However, certain states may still require intrastate authority for specific hauls, particularly when moving regulated commodities or serving dedicated contracts within state borders. Always double-check state-specific rules to avoid costly fines.

Licensing, Numbers, and Insurance Requirements

When it comes to operating authority, your business type matters. An interstate for-hire carrier must have both a USDOT number and an MC number issued by the FMCSA. These identifiers allow you to legally haul freight across state lines for compensation. If you're sticking to intrastate trucking, you might only need a state-issued DOT number or permit. Again, it all comes down to where and what you’re hauling.

Insurance is another area where the difference between interstate and intrastate becomes significant. For interstate operations, you’re required to meet federal insurance minimums, which can go as high as $5 million for hazardous materials. 

In contrast, intrastate operations typically follow much lower state-set insurance thresholds, often ranging from $50,000 to $300,000. These financial requirements reflect the broader risk and regulatory oversight that comes with crossing state lines.

So, what should you choose—interstate or intrastate? If you’re just starting and want to gain experience locally, an intrastate CDL is a smart stepping stone. 

But if you’re planning to scale your business, haul high-value loads, or work with national freight brokers, upgrading to an interstate CDL is the way forward. It unlocks broader opportunities, higher-paying routes, and the ability to partner with interstate carriers and freight companies.
