The short version: a Utah single-trip permit starts at $0 before bands, overweight and the transaction charge; an escort is first required at 12' or more wide; and the load becomes a superload at a gross weight the state does not publish. Everything below carries the Utah document it came from, that document's own revision date, and the date we read it.

4. How Utah prices overweight
§ 72-7-406(7)(b)(i) prices the single-trip overweight permit at "$.012 per mile for each 1,000 pounds above 80,000 pounds subject to the rounding described in Subsection (7)(c)", floored at $80 and capped at $540. Below 125,001 lb the charge is § 72-7-406(6)(b)'s flat $60, held as a weight-banded rate of zero per mile with a minimum and maximum of $60.
5. Utah'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 Utah 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. Utah publishes a real dimensional police trigger — R909-2-14 Table 3 requires "2 pilot escorts and at least 2 police escorts" over 20 ft wide on a freeway, 17 ft on a secondary highway, 175 ft long or 17 ft 6 in high — and no rate at all. R909-2 (all thirty-three sections), Utah Code §§ 72-7-402/404/406/407, three UDOT pages and the Utah Highway Patrol site were searched. R909-2-16(4)(e) says only "the permittee will assume all costs when a certified police escort or escorts are required", and R909-2-14(1)(c) puts the COUNT outside UDOT: "The number of police escorts required is determined by the Utah Highway Patrol." The $40.00 minimum UDOT does publish is for a DEPARTMENT employee and vehicle, not for police, and is itself a floor — "or the full cost ... whichever is greater".
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 Utah.
Utah 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.

Questions
How much is an oversize permit in Utah?
The single-trip base is $0, before the dimension bands, the overweight component and the transaction charge. The base alone is rarely what is paid.
When does Utah require a pilot car?
The first width trigger is 12' or more, and it varies by road class — the figure shown is the lowest across classes.
What is a superload in Utah?
Utah publishes no gross-weight superload threshold in the documents on file — see the superload section, which shows the dimensional triggers it does publish.
