The short version: a Pennsylvania single-trip permit starts at $0 before bands, overweight and the transaction charge; an escort is first required at over 13' wide; and the load becomes a superload at over 201,000 lb. Everything below carries the Pennsylvania document it came from, that document's own revision date, and the date we read it.
Corridor
1. Where the load goes next
The jurisdictions this one borders, each chip carrying the fact that decides whether that crossing is the expensive one — so the row is itself a small comparison. A multi-state lane is the actual job, and from here it is one click per state rather than a return to an alphabetical index.
Anything over one of these needs a permit. Every value links to the document that sets it.

Gross weight
80,000 lbrev. · read §4941: "no combination driven upon a highway shall have a gross weight exceeding 80,000 pounds, or the applicable weight set as forth in subsection (b) or (c), whichever is less." §4941(d) allows a natural-gas or battery-electric vehicle up to 2,000 lb more, limited to the qualifying equipment-weight difference; powertrain is not collected on a quote, so the allowance is recorded and not applied.
Single axle
20,000 lbrev. · read §4943(1): "The maximum axle weight upon a steering axle shall not exceed 20,000 pounds", and a combination over 73,280 lb may not exceed 20,000 lb on any single non-steering axle. Every axle is additionally capped at the lesser of this and the manufacturer's rated capacity, which a quote does not collect.
Tandem axle
34,000 lbrev. · read From the Chapter 185 Bridge Formula Table, "For Determining Maximum Axle Weights When Registered and Gross Weight Exceed 73,280 Pounds": a 2-axle group at 4 ft centre-to-centre is 34,000 lb. Pennsylvania publishes NO universal tandem figure independent of spacing — group limits rise with spacing — so 34,000 lb is the closest-spaced case and is a floor, not a general rule.
Not one number per dimension — the whole staircase. Each row is a condition the state actually publishes, what it requires when that condition holds, and the clause it comes from. Where a rule requires escorts and the source states no number, the row says that in the source's own words rather than reporting no requirement.

width from 13' (exclusive) to 14' and overall length from 90' (exclusive) to 120'
1 certified escortAdvisory: 75 Pa.C.S. §4962(f.2): a load over 13 ft but not over 14 ft wide needs only ONE pilot car even where its length would otherwise add a second, and "the position of the pilot car to the front or rear of the permitted vehicle may be determined by the department".
the vehicle is transporting building and width over 16'
Escorts required; the source states no number — at least 1. Published as: “67 Pa. Code §179.10(12) "Police escort. An escort is required as follows: (i) An escort by uniformed State Police or local police shall be required in the following instances: (A) Buildings in excess of 16 feet in width. (B) Super loads." EXCLUSIVE ("in excess of"). No number of officers is stated; one is billed as the floor. (iii): "If an escort by the State Police is necessary, the application shall be submitted to the Department to allow for the State Police to be notified by the Central Permit Office at least 24 hours prior to initial movement under the permit." Pennsylvania publishes no trooper rate.”
width over 16' or overall length over 160' or gross weight over 201,000 lb
1 certified escortAdvisory: 75 Pa.C.S. §4962(f.6): "(1) A super load, as defined in section 3108(c) ..., shall be required to maintain one certified escort vehicle under section 4573(b) ... (2) The requirements of this subsection are in addition to, not in lieu of, all other pilot car requirements for the super load movement." Its driver must be certified and licensed by PennDOT (§3108(a)), so a certified escort may bill above an ordinary pilot car; it is priced here on the same pilot-car band.
Escorts required; the source states no number. Published as: “Section 4 requires PSP when the load exceeds the Section 3 CEV conditions: up to 18 feet wide and up to 260 feet long on highways with at least two lanes in one direction. The Department and PSP determine the assignment.”

up to 14 ft wide — PennDOT current schedule (the §1904-adjusted §1942(a)(1) fee)
$46rev. · read Row "66 - A Vehicle (Oversize) Single Trip $46 (If < 14' wide) + .04 ton-mile for overweight". EXACTLY 14 FT IS IN THIS BAND (2026-11-07, state-matrix M51): the $46 is §1942(a)(1)'s fee as adjusted under §1904 ("every fee charged under this title"), and (a)(1)'s category is "a width up to 14 feet" — inclusive. The PDF's shorthand "< 14'" / "> 14'" names the two statutory categories and assigns 14 ft to neither; the statute assigns it to (a)(1). Before this a 14 ft 0 in overweight load matched no band and its oversize fee was unpriced.
over 14 ft wide — PennDOT current schedule
$97rev. · read "$97 (If > 14' wide)". Strictly "> 14'", so a load of exactly 14 ft is not in this band either — the current PDF assigns that width to no band at all.
up to 14 ft wide, within legal weight — 75 Pa.C.S. §1942 statutory amount
$35rev. · read "(1) Oversize vehicle or load, or both, having a width up to 14 feet and not exceeding legal weight limit, $35." CONFINED TO LEGAL WEIGHT, AND THE REASON IS STATED (re-read 2026-11-07, state-matrix M51): §1942(b) does say that "a vehicle and load which are both oversize and overweight would be subject to a fee under subsection (a)(1) or (2) and subsection (a)(3)", so (a)(1)'s CATEGORY reaches an overweight load too — but its $35 is the pre-§1904 AMOUNT, and PennDOT's adjusted $46 is what an overweight load is actually charged ("$46 (If < 14' wide) + .04 ton-mile for overweight"). Recording the stale $35 against an overweight load would add no fact, and wherever a requirement conflict is live (every Pennsylvania super load, over the police-escort rule) it would turn the priced $46 into an unpriced $35–$46. So the statutory row stays on legal-weight loads, where it records the spread it was kept for. Retained, not discarded: §1904 CPI-adjusts every Title 75 fee every 24 months and PennDOT's adjusted figure is $46, but §1942 has not been amended and still prints $35. Both are official for a load WITHIN legal weight; the engine reports the spread rather than choosing.
over 14 ft wide, within legal weight — 75 Pa.C.S. §1942 statutory amount
$71rev. · read "(2) Oversize vehicle or load, or both, having a width exceeding 14 feet and not exceeding ANY legal weight limit, $71." The CPI-adjusted counterpart is $97, and the row is confined to legal weight for the reason given on the (a)(1) row: an overweight load owes the ADJUSTED (a)(2) fee and (a)(3) cumulatively under §1942(b), and PennDOT's own single-trip row prints exactly that pairing: "$97 (If > 14' wide) + .04 ton-mile for overweight".

A permit priced against an unposted-road assumption in March is simply wrong, and wrong in the expensive direction. This is the window we watch, the basis for that window in the state's own orders or statute, and the authority that posts it.
Seasonal posting
Programme
Local roads only — the state system is not postedPennsylvania regulates weak roads through YEAR-ROUND posting and bonding, not through a spring thaw season. A posted-and-bonded road is restricted in July as well as in March, so it is a routing question rather than a seasonal one.
Charges exist and no schedule is published. PennDOT publishes no numeric State Police escort rate — "State escort fees vary based on escort personnel status (e.g., overtime) and will be invoiced separately".
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".
Holiday, curfew and night-travel windows are not yet encoded for Pennsylvania. The seasonal picture — which is a different question — is in section 6 above.
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.
Who issues it
11. 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.

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 Pennsylvania require a pilot car?
The first width trigger is over 13'.
What is a superload in Pennsylvania?
Pennsylvania's published gross-weight superload line is over 201,000 lb. It is not 80,000 lb; that is the federal legal gross limit, not a superload threshold.
Do Pennsylvania's own documents contradict each other?
Yes, in 2 place(s) we hold both documents for. They are set out in full above, each with its pinpoint citation, and none of them has been adopted.
