Route permit checker
Rates verified · By TruePermit · Free, no signup
States don't publish a combined answer to “what does my run require?” — carriers reconstruct it from five weight-distance programs, IRP/IFTA thresholds, and fifty permit fee schedules. This checker does the reconstruction: pick the states, set the combined weight, and the same deterministic rules that power the TruePermit dashboard resolve what applies — with official per-trip permit prices when you don't hold IRP or IFTA.
States this run touches
Tap every state on the route — pass-through miles count everywhere.
Truck + trailer + load — the combination, not the tractor alone.
Axles (combination)
Hazmat
Pick at least one state to see what the run requires.
How the checker decides
Every verdict is a rule, not a lookup table of guesses: interstate operation from the state count; IRP and IFTA from the 26,000-lb / 3-axle qualification test; each weight-distance state from its own statutory threshold — Kentucky at 60,000 lbs, New York at 18,001, New Mexico over 26,000, Oregon and Connecticut at 26,000-class lines; hazmat from the cargo class. Per-trip permit fees come from each state's official published schedule and are shown only when the credential they substitute for is actually required and actually missing.
The break-even question this exists to answer
Trip permits are the legal bridge for the occasional run — but they're priced like a bridge toll. A carrier crossing the same three states monthly pays those flat fees twelve times a year; apportioning once usually wins well before that. Run your own numbers: check the states, uncheck the credentials you don't hold, and compare the per-run total against what the registration stack actually costs.
Frequently asked questions
What permits do I need to run through another state?
It depends on the states, your combined weight, and what credentials you already hold. Above 26,000 lbs (or with 3+ axles) interstate runs need IRP apportioned registration and an IFTA license — or a per-trip permit and fuel permit in each state instead. Five states add their own weight-distance tax accounts on top: Kentucky (KYU, from 60,000 lbs), New York (HUT, from 18,001), New Mexico (WDT, over 26,000), Oregon (weight-mile) and Connecticut (HUF). This checker resolves all of it from your route footprint.
Does weight mean my truck or the whole combination?
The combination — tractor plus trailer plus load. That's the trap that catches hotshots: a dually that never reaches 26,000 lbs alone crosses the IRP/IFTA line the moment a loaded trailer is hitched. Enter the heaviest combined weight the run will see.
Can I use trip permits instead of IRP and IFTA?
Yes — every state sells a temporary trip permit (typically 72 hours) and a fuel permit as the per-trip alternative for vehicles not apportioned or IFTA-licensed there. It's legal and sometimes the right call for a rare out-of-state run; the checker shows each state's official fee so you can see when a few runs a year start costing more than apportioning.
Do pass-through states count even if I don't pick up or deliver there?
Yes. Weight-distance taxes, IFTA fuel tax and permit requirements attach to miles driven in the state, not to freight activity there. A state you only cross still taxes the crossing.
Are the fees shown official?
Fees marked 'official' come from each state agency's published schedule, tracked with its source. Where a state prices by formula rather than a flat amount, the checker says so instead of inventing a number — and oversize/overweight and hazmat route restrictions are flagged for verification, never auto-cleared.
