The short answer
An oversize permit is two costs stacked on top of each other: the state’s own permit fee, which you would pay no matter who files it, and the service fee charged by whoever does the filing.
Thirty-five states charge one flat rate for a single-trip oversize permit, and those run from $6 in New Hampshire to $75 in Ohio. The other thirteen cannot be reduced to one number — they price on weight, on width, on the dimensional envelope, or on distance travelled. That is the whole point of this guide.

What you actually pay
Every quote you get should break into these parts. If a service gives you one blended number with no breakdown, that is where the margin hides.
- State DOT permit fee — set by statute or the DOT fee schedule. Identical whoever files it.
- Service fee — what the permit company charges. This is the only part that is genuinely negotiable between vendors. Ours is $20 per state permit.
- County and city permits — charged separately, where your route leaves state-maintained highway.
- Escorts and pilot cars — billed by the escort provider at their own rate. See the pilot car guide.
- Engineering or bridge review — applies to superloads and some heavy configurations, and can run into the hundreds.
A state permit usually stops at the state highway line
If part of your route runs on county roads or city streets, the state permit does not cover it. Those jurisdictions issue their own, on their own timetable. This is the single most common reason a driver with a valid permit still gets stopped.
Why one number per state is a lie
States do not price permits the same way. There are three models in use, and lumping them into one column is how permit-cost pages end up quoting numbers that are wrong for most loads.
Flat rate
One fee, regardless of how far over legal you are, within permit limits. Simple to quote and simple to verify, and it is how most of the country works — 35 states, from New Hampshire at $6 and Oregon at $8 through Texas at $60 and Ohio at $75. Louisiana is the one variant: its $10 is charged per day the permit is valid rather than per trip.
Gross-weight bracket
The fee steps up in bands as gross vehicle weight rises. Alabama is the clearest example: a single-trip permit is priced in four brackets — $20, $40, $70 and $110. A light over-width load and a heavy one are not the same permit fee, and quoting $20 as “the Alabama fee” is wrong three times out of four.
Dimensional envelope
The fee is a function of the load’s envelope — width, height, length and overhang bands, sometimes in combination. Arizona, Florida, Illinois and Indiana all price this way. There is no single figure to quote, only a rule that maps your dimensions to a price.
| Model | What moves the price | Can it be one number? | States |
|---|---|---|---|
| Flat rate | Nothing, within permit limits | Yes | 35 — incl. CA, TX, OH, OR |
| Weight bracket | Gross vehicle weight | No — a range, plus the bracket you land in | 1 — AL |
| Width bracket | Width alone | No — a range | 2 — PA, SC |
| Dimensional envelope | Width, height and length together | No — depends on the load | 5 — AZ, FL, IL, IN, WI |
| Per-dimension | Which dimensions you exceed | No — charged per dimension | 4 — ME, NC, NJ, TN |
| Base + per-mile | Distance travelled | No — route decides it | 1 — WY |
You do not have to work this out. Send us the dimensions and the route and we will come back with the exact states, the exact DOT fees, and a total — before anything is charged.

No state matches that
Try the two-letter code — TX, PA, CA — or the full state name.
Every row stays in the page whether or not it matches your search — filtering hides rows, it never removes them. Permigo’s $20 service fee is separate from, and on top of, the DOT figure shown.
What pushes the price up
The base fee is rarely the whole bill. In rough order of how often they bite:
- Crossing into superload territory. Every state sets its own superload threshold. Above it you are into engineering review, longer lead times, and fees several times the routine rate.
- Escort requirements. Triggered by width, height or length, and often by road type as well. Escorts are billed by the provider, not the DOT.
- Bridge and route analysis. Some states run this manually for heavy configurations and charge for it, sometimes scaled by trip distance.
- Local jurisdictions. County and city permits along the route, each with its own fee and its own office hours.
- Curfews and travel windows. They do not add a line item, but a load that cannot move until Monday morning costs real money.
Annual vs single-trip
If you run the same lane repeatedly with a consistent configuration, an annual or blanket permit usually beats a stack of single trips — both on fees and on the time spent filing. The trade is flexibility: annual permits are tied to specific vehicles, dimension limits and sometimes specific routes, so a load that exceeds the annual’s envelope still needs a single trip.
The break-even depends entirely on the state and how often you run it. Permigo charges the same $20 to file either one, so the only variable is the state’s own fee.
Questions
How much does an oversize permit cost?
Two costs stack. The state DOT's own fee, which among our verified flat-rate states is one flat rate in 35 states, running from $6 in New Hampshire to $75 in Ohio, plus whatever your permit service charges to file it. Permigo charges a flat $20 per state permit. Bracket and envelope states are priced on weight or dimensions rather than a single figure.
Why can't you just show one fee per state?
Because for roughly a third of states one number would be false. Alabama prices a single-trip permit in four gross-weight brackets from $20 to $110. Arizona, Florida, Illinois, Indiana and Wisconsin price on the dimensional envelope, so width, height, length and overhang each move the fee. Showing the lowest bracket as if it were the fee is the most common way permit-cost pages mislead.
Does the state fee change if my load is heavier?
In bracket states, yes, directly. In envelope states the fee moves with dimensions rather than weight. In flat-rate states the base fee holds, but excess-weight surcharges, bridge analysis and escort requirements can still be added on top.
Do I need county or city permits as well?
Often. A state permit generally covers state-maintained highways only. Where your route uses county roads or city streets, those jurisdictions can require their own permit. We file those alongside the state permit rather than leaving them to you.
Is the Permigo fee included in the figures on this page?
No. Every figure here is the state DOT's own fee. Permigo's $20 is separate, flat, and charged once per state permit.
