Which rules apply to a load
Your truck's route doesn't settle it. FMCSA counts a load as interstate (opens in a new tab) when the freight started or ends in another state or country, even if your leg never crosses a state line.
What changes from state to state
- Authority for in-state loads. Many states license carriers that haul for pay inside their borders, separate from your MC number. California generally requires a motor carrier permit for paid property hauling at any weight. Kentucky requires intrastate for-hire licensing even for cargo vehicles under 10,001 pounds hauling Kentucky-only loads.
- A state number or your USDOT number. Some states use your USDOT number for intrastate trucks too. Others add their own, such as California's CA number from the Highway Patrol.
- Insurance minimums. Some states set their own intrastate liability tiers, and some of those are lower than the $750,000 FMCSA requires for interstate nonhazardous for-hire freight at 10,001 pounds GVWR or more. Your insurer often files the state's own proof form, such as Form E.
- Taxes on the miles you drive. Five states we checked charge a mileage tax: Connecticut, Kentucky, New Mexico, New York and Oregon. Each has its own weight trigger and filing. Illinois also offers optional mileage-tax plates for trucks that travel only in Illinois.
- Oversize and overweight permits. Each state that publishes oversize and overweight rules issues its own permits through its transportation agency or permit office.
How we check
Every row on a state page comes from the agency's own page, a statute or an administrative rule, with the date we read it. Where we couldn't confirm a rule from an official source, the page lists it under "Not covered yet" rather than guessing.
