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.
Legal limits
1. Pennsylvania legal limits
Anything over one of these needs a permit. Every value links to the document that sets it.
Over 13 ft but not over 14 ft wide and over 90 ft but not over 120 ft long — one pilot car only, positioned front or rear by PennDOT — amended 2014-06-30, effective 60 days laterrev. 2014-06-30 · read 2026-09-01
Super load, or a building over 16 ft wide — police escort requirement, on which the regulation and the later statute disagree — amended 2015-10-30, effective 60 days laterrev. 2015-10-30 · read 2026-09-01
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".
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
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.

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 1 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.
