What we cover, and what we do not

The 51 states with a jurisdiction file

A state is covered when it has a data file behind it: legal limits, a fee schedule, escort rules and superload triggers, every value carrying its own source document and effective window. The counts below are computed from those files, not maintained by hand.

The 0 we do not hold, and why they have no page

These states appear as a row on every topic table, marked "not yet covered", and nowhere else. No state page ships without a jurisdiction file behind it. A page titled "Wyoming oversize permits" that contains no Wyoming thresholds is worse than no page: it ranks, it is opened by somebody planning a real move, and it answers nothing. That pattern is common in this market and we are not reproducing it at any page length.

What we will not do to fill the gap: copy figures from another commercial site. Two of them publish permit fees for half the states under a title claiming all of them, cite no state DOT between them, and carry errors in the dangerous direction — a legal-limit figure a foot over the statute reads as legal and is not. Inheriting a chain like that is how a wrong number and a copyright problem arrive together.

The rules we hold ourselves to

• No value without a document. Every number is stored with its source, that source's own revision date, our retrieval date, and the window it is effective for.
• No adjudicating a conflict. Two in-effect official documents that disagree are both published and neither is adopted, and the calculator refuses to price that field.
• No filling a gap with a guess. A measurement we were not given evaluates to "cannot tell", never to zero and never to "no requirement" — because a requirement chosen by an absence is a confident wrong answer.
• Freshness is per fact, not per page. A page's modification date is the newest retrieval date among the sources actually rendered on it. It is never the deploy time, because a freshness claim we cannot substantiate per fact would cost us the only thing these pages have.
