The short version: a Wyoming single-trip permit starts at $25 before bands, overweight and the transaction charge; an escort is first required at no width the state publishes; and the load becomes a superload at a gross weight the state does not publish. Everything below carries the Wyoming document it came from, that document's own revision date, and the date we read it.
1. Wyoming legal limits
Anything over one of these needs a permit. Every value links to the document that sets it.

4. How Wyoming prices overweight
W.S. 31-18-804: "When an overweight permit is issued, the fee is six cents ($.06) for each ton or fraction thereof of weight in excess of the weight limitation under W.S. 31-18-802 for each mile traveled on the highways. In no event shall the fee be less than forty dollars ($40.00) for the permit."
5. Wyoming's superload threshold
Above one of these, the state stops issuing over the counter and prices the move after an engineering review.
| Trigger | Threshold |
|---|---|
| Gross weight | None published |
| Width | None published |
| Height | None published |
| Length | None published |
| Short axle spacing | Not yet covered |
6. Route survey and bridge review
The dimensions at which Wyoming triggers a physical route inspection or an engineering review, and what the agency charges to review it.
| Measurement | Inspection / review trigger |
|---|---|
| Width | Not yet covered |
| Height | Not yet covered |
| Length | Not yet covered |
7. Police escorts
Charges exist and no schedule is published. NOT CHECKED — a gap in our data rather than a finding about Wyoming, and the only row in this dataset of that kind. The research run that produced the Wyoming legal limits and fee schedule terminated mid-sentence partway through the fee section and never reached the escort rules, so neither an escort trigger nor a Highway Patrol rate has been read for this state. Wyoming permits 117,000 lb legal gross over mountain two-lane highways and certainly publishes escort triggers; every Wyoming load over a legal dimension is therefore sent to manual review rather than quoted at zero escorts. Chapter 5 § 5-6(c) separately makes the applicant pay "the cost of sending personnel to accompany load movement" above 250,000 lb, which is a departmental escort charge with no published rate. Remove this row when the escort section is sourced.
This is a positive finding: we searched and there is nothing to quote. It is not the same as "no police escort is ever required here".
8. When you can move it
Holiday, curfew and night-travel windows are not yet encoded for Wyoming.
Wyoming spring thaw restrictions →
Why those windows are absent rather than estimated
They are not guessed at here. What we do publish is the seasonal weight-restriction picture, with the date we last read each state's own bulletin — a curfew invented from a plausible pattern is worth less than an honest gap, because a reader cannot tell the two apart on the page.
9. Permit office
The agency behind each figure above is linked from that figure. We publish no per-state permit-office phone number.
Why there is no phone number here
We are not publishing per-state permit-office phone numbers yet, and the reason is worth stating: the two seed lists available for them are both demonstrably stale — the federal one gives two different states the same phone number — and a wrong number on a page like this costs somebody a morning. The agency behind each figure above is linked from that figure, which is the part we can stand behind today.
11. What this does not include
Named rather than gestured at, because each of these can exceed the permit itself. Every item is listed; open one for why it is excluded.
Line haul, fuel and driver time
This is a permit fee, not a freight rate.
Civilian pilot car rates
We hold no rate data, and the two commercial sites that publish market rates disagree by nearly a factor of two on the same service.
Route-survey engineering
The agency's review fee is shown where the state publishes one; the engineer's own fee is a private cost with no schedule.
Bonds and escrow
Set per move by the agency, and in at least one state the escort is billed at actual cost against it.
Utility coordination and line lifts
Arranged with each utility, priced by each utility.
Second-issuer permits
A toll, bridge or city authority inside the same state issues its own permit, and a state total that omits it is missing a whole permit.

Every document behind Wyoming2 sources
- Wyoming Administrative Rules, Agency 045 Subagency 0004 Chapter 5 § 5-6 — permit fees — Wyoming Department of Transportation (via Cornell LII) — SECONDARY — Cornell LII's copy, which states no revision date. It restates the statute's $25, $0.03 foot-mile and $0.06 ton-mile figures identically, which is the available cross-check, and adds the Class A-F, custom-harvest and recreational-vehicle products and the over-125-ton cost-recovery rule.

Questions
How much is an oversize permit in Wyoming?
The single-trip base is $25, before the dimension bands, the overweight component and the transaction charge. The base alone is rarely what is paid.
When does Wyoming require a pilot car?
Wyoming publishes no numeric width trigger for an escort in the documents on file. That does not mean none is ever required — see the escort section above.
What is a superload in Wyoming?
Wyoming publishes no gross-weight superload threshold in the documents on file — see the superload section, which shows the dimensional triggers it does publish.
