Every state your truck enters — including states you only drive through — can require its own permit, tax filing, or credential. Get one wrong and you’re looking at fines, delays, or an out-of-service order on the side of the highway.
This guide breaks down which trucking permits apply nationwide, which are issued state by state, which states add their own taxes, and how to keep every permit current across your fleet.
Quick answer: Most interstate carriers need four “everywhere” credentials — a USDOT number, IRP registration, an IFTA license, and UCR registration. On top of those, individual states may require trip or fuel permits, oversize/overweight permits, or weight-distance tax filings, depending on your route, vehicle, and load.

The Credentials That Cover All States
IRP Registration and Cab Cards
The International Registration Plan lets you register a truck once in your base state and pay apportioned fees to every jurisdiction you travel in. Your cab card lists each state where the truck is registered. All IRP member jurisdictions have accepted electronic cab cards since January 1, 2019.
IFTA License and Decals
The International Fuel Tax Agreement covers fuel tax reporting across member states and Canadian provinces with a single license and quarterly returns. The license can be carried electronically; the decals stay on the truck.
UCR Registration
Unified Carrier Registration is required for carriers operating in interstate commerce and renews every year by December 31 — one of the most commonly missed renewals.
State-Issued Trucking Permits
Trip Permits
If a truck isn’t registered through IRP for a state it needs to enter, a temporary trip permit lets it operate there legally. Trip permits are short-term — typically valid for a few days, with exact duration set by each state.
Fuel Permits
Carriers without an IFTA license can buy a temporary fuel permit for each state they enter. For fleets that cross state lines regularly, an IFTA license is almost always simpler.
Oversize and Overweight Permits
Any load that exceeds a state’s legal size or weight limits needs a permit from that state — and every state on the route, including pass-through states. Rules, fees, escort requirements, and travel restrictions vary widely. See our full guide on how to get an oversize load permit in each state.
States with Extra Taxes: Weight-Distance and Highway Use
A handful of states charge heavy trucks based on weight and miles driven in the state, on top of IFTA. If your route touches these states, you’ll need the right credential and regular filings:
- Kentucky — KYU weight-distance tax, for vehicles with a combined licensed weight of 60,000 lbs or more
- New Mexico — weight-distance tax, for vehicles over 26,000 lbs
- New York — Highway Use Tax (HUT), for vehicles over 18,000 lbs
- Oregon — weight-mile tax, for vehicles over 26,000 lbs
- Connecticut — Highway Use Fee, for vehicles over 26,000 lbs (in effect since 2023)
Always confirm current thresholds and rates with each state before you run — these programs change.
How to Get Trucking Permits by State: Step by Step
- Map your full route and list every state. Include every state you’ll drive through without stopping — each one is a potential permit requirement.
- Check your “everywhere” credentials first. Confirm IRP, IFTA, UCR, and your USDOT number are current. If they are, many routes need nothing else.
- Identify state-specific requirements. For each state, check whether your load or vehicle needs a trip permit, fuel permit, oversize/overweight permit, or weight-distance tax credential. Each state DOT’s website is the authoritative source.
- Gather your documents. You’ll typically need your USDOT number, registration, vehicle dimensions and weights, axle configuration, and route details.
- Apply through each state’s permit portal or a permit service. Many states issue permits online, and permit services can handle complex multi-state moves on your behalf.
- Get approved permits to the right driver, in a format they can always open. Scale houses and remote routes often have weak signal, so store permits on the driver’s device rather than relying on a cloud link. Digital Permit Book pushes permits straight to the driver’s app, where they open instantly even offline.
- Track every expiration date. IRP, IFTA, UCR, and state permits all renew on different cycles. Digital Permit Book tracks each date and sends automatic alerts before anything lapses.

Can Drivers Carry State Permits Electronically?
Yes, in most cases. Federal rules under 49 CFR 390.32 allow required records to be kept electronically, IRP cab cards and IFTA licenses have been accepted electronically in every member jurisdiction since 2019, and most states accept electronic copies of their own permits. A few state permits still have paper requirements, so check before you run. For the full breakdown, see what each state accepts electronically.
Frequently Asked Questions
Do I need a permit for every state I drive through?
Not always. If your truck has IRP registration and an IFTA license covering a state, you usually don’t need a separate trip or fuel permit there. You will need a state permit if your load is oversize or overweight, if the state isn’t on your IRP registration, or if it charges a weight-distance tax.
What’s the difference between IRP and a trip permit?
IRP is an annual registration covering every jurisdiction you list. A trip permit is a short-term, single-state permit for a truck that isn’t registered in that state.
Which states have weight-distance taxes?
Kentucky, New Mexico, New York, and Oregon charge weight-distance taxes, and Connecticut charges a Highway Use Fee on heavy trucks.
How do fleets keep track of permits across all states?
Most fleets use permit management software that stores every permit by truck and trailer, tracks expiration dates, and pushes current documents to drivers. Digital Permit Book does this for fleets from 5 to 1,000+ trucks.
