When a truck accident happens in Texas, one of the first questions that comes up is whether the truck was operating interstate or intrastate. Understanding the difference between Interstate and Intrastate motor carriers is crucial, as this distinction is not just technical—it determines what safety rules apply, what insurance coverage is required, and ultimately how a personal injury or wrongful death claim will be handled.
Understanding the difference can help you know your rights and what to expect after a crash.

The Federal Motor Carrier Safety Administration (FMCSA) defines interstate commerce broadly. For example, if a Houston-based trucking company hauls goods from the Port of Houston to a Dallas warehouse, but those goods are destined for Oklahoma, the operation still counts as interstate commerce, even if the truck never leaves Texas.
One major difference between interstate and intrastate trucking is how long drivers are allowed to be on the road:
These differences matter because fatigue is one of the leading causes of truck crashes, and accident victims need to know which rules applied to the driver at the time of the wreck.
Another big distinction is insurance coverage:
For accident victims, this often means interstate cases have more coverage available to pay medical bills, lost income, and other damages.
Knowing the type of truck involved can help determine whether the driver should have been following federal or state rules.
A quick way to tell is by looking at the numbers painted on the side of the truck:
Police reports, shipping paperwork, and insurance filings also help establish the truck’s classification.
There can be confusion with larger trucking companies, as they will have a mix of in-state and Interstate authorized equipment. It is up to the vehicle or asset manager and the dispatcher to determine which vehicles or assets are used in various cargo-moving situations. The distinction between intrastate and interstate makes a difference in some of the regulations that may apply to a driver.
Ensuring that the correct loads go on the appropriately approved equipment becomes an issue for insurance. If an intrastate vehicle is used to transport Interstate products across state lines, there can be huge financial losses if an 18-wheeler accident occurs.
The regulations, financial, and administrative logistics of such companies are highly complex. Whether on an interstate highway or engaged in interstate commerce, the rules matter.
Whether a truck is classified as interstate or intrastate affects:
Getting this classification right can mean the more likely you are to get full compensation for your case.

Although the highway the trucker is on at the time of a crash is not relevant to their intrastate or interstate status, the following guidelines can help determine the status of a highway.
There are clear indicators to look out for to determine whether you are traveling on an interstate or intrastate highway. Firstly, on interstates, you will typically come across signs that display the word “Interstate” followed by a numerical designation. These signs serve as a clear indication that you are on a U.S. highway. On the other hand, if you are driving on an intrastate road, you can identify it by observing signs that display “State Highway” followed by a specific number. These distinct signage conventions allow you to easily differentiate between interstate and intrastate routes as you navigate the roadways.
After a truck accident, victims often face overwhelming medical bills, missed work, and uncertainty about the future. Determining whether the truck was operating interstate or intrastate is a critical step in protecting your rights.
