Figures in circulation, against the statute

Numbers that circulate widely in oversize and overweight work, answered with the primary document — and with the mechanism that produced the real figure, so it degrades gracefully instead of going wrong again.

The short version: 12 figures that circulate widely in oversize and overweight work are set against the primary document that governs them. Each entry shows the circulating claim, the figure the state's own document carries, and that document's revision date beside the date we read it — all of it visible without opening anything. The fold under each one holds the mechanism: the surcharge statute, the inflation cycle or the dropped line item that produced the gap.

How to read this

How to read this page

Each entry states a figure that is in circulation, then gives what the primary documents actually say — with the document, its own revision date, and the date we read it.

Why nothing here is attributed

Nothing here names or links to another site, and nothing here imputes intent: a number can circulate for years without anyone being at fault, and the useful thing is the statute, not the attribution.

Errors versus genuine disagreements

Where a figure turns out to be a genuine disagreement between two official documents rather than an error, it is marked as such and shows both. That distinction is the difference between authority and embarrassment, and there are entries below on both sides of it.

A superload is anything "over 80,000 lb"

What the documents actually say, and why the figure moved

80,000 lb is the federal LEGAL gross limit on the Interstate System under 23 U.S.C. §127. Above it a load needs an overweight permit — an ordinary over-the-counter product. A superload is something else entirely: a move the state will not issue over the counter, and prices only after an engineering and route review. The published gross-weight lines in our own data start well above 100,000 lb and run past 250,000 lb, so treating 80,000 as the line misstates it by a multiple in every state that publishes one.

Georgia's superload line sits at 150,000 lb

over 180,000 lbGa. Comp. R. & Regs. Rule 672-2-.01 — superload definitions (last amended 2012-10-16) — "a gross vehicle weight exceeding 150,001 pounds up to a gross vehicle weight of 180,000 pounds"; "Superload Plus: A non-divisible load exceeding a gross vehicle weight of 180,000 pounds"; the axle-data requirement above 150,000 lb

What the documents actually say, and why the figure moved

Georgia's own rules define superload treatment above a gross vehicle weight of 180,000 pounds. 150,000 lb is where the FEE steps — a band edge in the fee schedule, not a classification threshold. The two are different kinds of number and a fee-band edge does not decide whether a move needs engineering review.

Tennessee allows a 53 ft semitrailer

52'Tenn. Code Ann. § 55-7-201 — Length limits (via Justia — SECONDARY source) — (b) 45 ft single unit and 65 ft for a truck-and-trailer combination; (c) the 52 ft towed vehicle and the 41 ft kingpin condition; (d) 28 ft 6 in twins; (f) 75 ft for single-length logs, poles or timber
rev. 2025 · read 2026-09-03
What the documents actually say, and why the figure moved

The Tennessee statute states that the towed vehicle shall not exceed fifty-two feet. A standard 53 ft van therefore reads legal in Tennessee and is not. This is the dangerous direction of error — a figure a foot over the statute puts an illegal trailer on the road with the driver believing otherwise.

Louisiana allows 14 ft of height

13'6"La. R.S. 32:381 — Height of vehicles (via Justia) — 13 ft 6 in generally; 14 ft for a vehicle operating EXCLUSIVELY on the interstate system with one road mile of access
rev. 2025 · read 2026-09-03
What the documents actually say, and why the figure moved

The general Louisiana height limit is 13 ft 6 in. Fourteen feet applies only on the interstate system, as an exception — so a 13 ft 9 in load reads legal on the general figure and is not legal on the state system. Publishing the exception as though it were the rule is again the dangerous direction.

Colorado allows 14 ft of height

rev. 2016-08-10 · read 2026-09-03
What the documents actually say, and why the figure moved

Colorado's statutory height limit is 14 ft 6 in. This one errs in the safe direction — a load built to 14 ft is legal — but it costs money in the other way, by sending a load to a permit it does not need.

Georgia's overall length limit is 65 ft

What the documents actually say, and why the figure moved

Georgia publishes an overall length limit of 100 ft including overhang. A 65 ft figure would send an ordinary legal combination to a permit it does not need.

What the documents actually say, and why the figure moved

This one is more interesting than a correction: Georgia's own documents do not agree with each other. A grandfathered figure above the federal 20,000 lb limit is corroborated by the federal compilation's own appendix, and another official source states the federal figure. Both are on file here and neither has been adopted — which is why this entry shows a disagreement rather than a corrected number.

New Jersey adds a "12% service charge" to a permit

$12 + 5%NJDOT — Permit Fee Schedule (PDF, undated) — "$10 Base Fee + any excess weight fees + $12 Transaction Fee + 5% Service charge"; "$1.00 per foot (or fraction thereof) in excess of 14 feet in width"; "NOTE: 5% leeway is given on axle weights."
undated document · read 2026-09-02
What the documents actually say, and why the figure moved

The New Jersey charge is a FLAT $12 per permit plus a percentage — not 12 percent. On a small permit the difference is roughly a doubling of the out-the-door cost, and it goes the wrong way for anyone budgeting from the smaller figure. Reading a flat dollar amount as a percentage is a specific and repeatable error, which is why the mechanism is published here alongside the number.

A Colorado single-trip oversize permit costs $15

$30CDOT Freight — Permitting Information (undated) — "Single Trip Oversize: $15* and total of $30"; "Single Trip OSOW: $15 plus $5 per axle* and a total of $30 plus $10 per axle"; "Credit Card Fee: $4 per transaction per permit"; the SB 09-108 surcharge note and its six-axle worked example
undated document · read 2026-09-03
What the documents actually say, and why the figure moved

The $15 in the Colorado permit statute is never payable on its own: a separate statute imposes a surcharge equal to 100% of the fee, doubling it, and the state's own worked example runs $45 → $90 → $94 with the card charge. The figure we hold is the doubled one, because that is the amount actually charged. Publishing the mechanism — a statutory fee plus a 100% surcharge under a different statute — is what stops this figure going wrong again the next time either half moves.

A Texas oversize/overweight permit tops out at $435

What the documents actually say, and why the figure moved

Texas's own fee table prints a $60 base, a top maintenance band of $375 and a $35 vehicle supervision fee in the same cell — $470, not $435 — and the state's payment processing (a small flat amount plus a percentage) takes it above $480 out the door. The $35 supervision fee is the component most often dropped, and it is printed in the same table as the two figures that are kept.

A Pennsylvania single-trip oversize permit costs $36

What the documents actually say, and why the figure moved

No document in the Pennsylvania record contains $36. Two figures do exist and both are official: the fee statute still prints $35, and PennDOT's current schedule prints $46 — because a separate section of the same title CPI-adjusts every fee in it every 24 months, and $46 is what that adjustment produced. This is therefore a live disagreement between two current documents rather than an error, and it is published as such. It is also why a bare "$46" would repeat the exact mistake being corrected: the figure is on a fixed adjustment cycle and will move again.

A single published contact list gives every state permit office

What the documents actually say, and why the figure moved

The most widely-circulated federal contact list gives two different states the same telephone number, carries at least one legacy path, and stamps itself with a date computed from a file timestamp — with a fallback that prints today's date when the parse fails, so it always looks current. That is why we publish no per-state permit-office phone numbers yet: the seed lists are stale, and a wrong number on a reference page costs somebody a morning. The agency behind each individual figure on this site is linked from that figure instead.

Common questions

Questions

Whose figures are these?

Deliberately unattributed. Each entry states a figure that circulates and answers it with the primary document, because the useful claim is "here is what the statute says" — a reader who arrived with a wrong number needs the right one, not a name.

How do I know YOUR figure is right?

You do not have to take it. Every corrected figure above links to the state document it came from and carries that document's own revision date beside the date we read it, so it is checkable against us as well as against anything else.

Why publish the mechanism as well as the number?

Because a corrected number goes stale the same way the original did. One state on this page adjusts its permit fee for inflation on a fixed 24-month cycle; another doubles its statutory fee under a separate surcharge statute. Publishing only the current figure would reproduce the fault being corrected.

What if two official documents disagree?

Then it is not a correction, and it belongs on the source-notes page instead. Several entries above are exactly that, and they show both documents rather than adopting one.
