State permit guides got a lot better today
Bug FixDataFeatureA big batch of improvements to the per-state permit guides at /states.
**Fee sections are now honest.** Two bugs killed: about 21 state pages were rendering "starting at $" with no number (or "$null" in the FAQ) because the underlying field is null on states that don't publish a separate overweight-only base fee, and every state page said "the fee climbs with gross weight" even on flat-fee states like Massachusetts ($40 flat irreducible single trip), Arizona, Kansas, and Vermont where it just isn't true. Both gone.
**OS fees section now lists dimension-triggered surcharges** for the 16 states that have them: Arizona's Class C review ($15 at width >14′, height >16′, or length >120′; +$10 if width/height >18′), Colorado's 2× base multiplier under SB 09-108 plus the $110 Chapter 6 Special, and similar surcharges for DE, FL, GA, IL, IN, KS, ME, MO, NJ, OH, SC, TN, WI, WY. Pulled directly from the same data the calculator runs against, so the page can't disagree with what calculator quotes. States without surcharges get a terse, honest two-sentence section instead of fabricated prose.
**OW fees section is now hand-authored per state.** Each state gets a public summary describing the fee model in plain English: flat / per-ton-mile / gross-weight-bracket / per-axle / two-tier / etc. Plus the named portals and systems (Oregon's RUAF table, New York's HOOCS via OSCAR, IL's IDOT Table 2), federal/state legal-GVW divergences (NM's 86,400 lb bridge formula, ME's 100k 6-axle grandfather, ND's 105,500 lb state highway), and add-ons when present (Massachusetts's $350 MassPike engineering review, Texas's $500 superheavy engineering analysis at >200,001 lbs, Illinois's tollway permits + ISP escort, Maryland's >130k state police escort). Same model label coverage as before — now backed by per-state prose.
**Size/weight/escort summary table redesigned** on every state page. Now a proper table with three columns (Dimension | Legal limit | First escort trigger) instead of a stacked label/facts list. Pole escort triggers get a "(pole)" suffix where applicable. Overhang clutter removed from the summary view (still computed by the calculator).
**Heavier states now contextualize their headline GVW number.** Maine's "100,000 lb" non-interstate now reads "80,000 lb interstate (up to 100,000 lb with 6+ axles)" — surfacing the 6-axle grandfather rule that was previously hidden. South Dakota non-interstate now reads "80,000 lb non-interstate (up to 95,000 lb with 7+ axles)" — the state's axle-count-dependent legal GVW. Montana's 131,060 lb and Wyoming's 117,000 lb non-interstate caps get a clarifying note that they're conditional on high axle counts and long wheelbases, not flat for typical configurations.
**Axle calculator now respects South Dakota's axle-count-dependent legal weights.** A 5-axle truck at 85,000 lbs in South Dakota on non-interstate now correctly passes the GVW check (previously it failed at the federal 80,000 lb cap, which only applies to the Interstate in SD). Same for 6-axle (90k) and 7+-axle (95k). Per ARSD 70:03:01:02.
**South Dakota interstate legal height corrected** to 14′ on the /state-regulations height map and table (was previously shown as 13'6"). South Dakota's prose guide at /states/south-dakota also got a Nick-voice rewrite covering daylight triggers, Extended Period permits, Black Hills civilian escort routes, and the bridge clearance + posted-structures lists.
How to Quote a Load: a four-part video guide
FeatureNew step-by-step guide at /how-to-quote-oversize-overweight-loads that walks the whole quoting workflow on video, with a timestamped key-moment list under each clip so you can jump to the part you need. Four parts: entering the load and route, reading the per-state permit and escort results, building the bid, and saving and sending a branded customer quote.
The videos are click-to-play, so the page stays fast until you actually start one, and each section lists the key moments with timestamps. Find it in the new Video Guide section on Resources, in the footer, or from the "New here?" link on the calculator.
Length escort map, plus annual and state-regulation upgrades
FeatureDataNew interactive Length Escort map on the State Regulations page (/state-regulations), alongside the height and pilot-car maps. It shows the overall combination length at which each state first requires an escort on the Interstate, from 75′1″ in Georgia to 160′ in New York, with the odd ones flagged: Georgia lets amber lights stand in for the escort between 75′ and 100′, Utah's escort is night-only until 120′1″, Arizona's is a case-by-case police call over 120′, and Idaho, Montana, and Oklahoma set no interstate length limit at all.
Arizona's width map now notes that its 11′1″ pilot-car requirement only applies at night or on weekends, so you are not over-quoting a daytime weekday run.
The annual permit guide (/annuals) now opens with every state expanded, so you can scan or search all 48 without clicking, and it leads with the real spread of annual fees: $8 to $6,000 depending on the state and permit class.
Each map on the State Regulations page now links straight to the full per-state guide for the deeper detail.
Per-state oversize permit guides
FeatureDataNew per-state permit pages at /states — one guide for every contiguous state (/states/texas, /states/california, and 46 more), plus a /states index. Each pulls together that state's legal size and weight limits, axle weight limits by road class, superload thresholds, the point where escorts and pilot cars first kick in, single-trip and annual permit fees, travel and holiday restrictions, special-commodity rules, and the official DOT permit office, all from current DOT data.
Find them under Resources, or jump straight to your state at /states/[your-state].
Customer Quote PDFs: upload your own logo
FeatureOrg owners can now upload a custom logo for customer-facing quote PDFs. Set it once in Customer Quote Settings (gear icon next to the Saved tab on your dashboard) and every customer-quote export your team generates will use it — replacing the OSOWloads mark in the header. A small OSOWloads mark stays in the bottom-right footer for attribution.
PNG, JPEG, and WebP up to 250KB. For crisp rendering on the PDF, upload a source image at least 600×200 px — smaller logos look soft because PDFs embed raster pixels and viewers can't sharpen them after the fact. Your browser resizes the logo before upload so high-res sources won't slow anything down.
The gear icon now shows a thumbnail of your logo when one is set — at-a-glance confirmation that your branding is configured. Remove anytime to revert to the OSOWloads default.
Per-state oversize surcharges and Fee Notes
FeatureDataBug FixThe OS fee column now reflects state-specific surcharges. Hover any row to see the breakdown — for example, "$15 base + $250 movement feasibility = $265" for a Missouri superload. Encoded for 12 states (MO, GA, KS, AZ, WI, SC, TN, IN, DE, FL, OH, CO), including Colorado's 100% single-trip multiplier. For 4 more states with formulas we can't fully encode (ME, TN, NJ, WY, IL), the tooltip surfaces an informational note so the displayed fee isn't silently under-reported.
Each state's `Fee Notes` is now selectable in the State Notes dropdown.
Bug fix: when a route mixed states with definite police escort counts and case-by-case states, the totals card and table footer were erasing the definite count and showing only the CBC warning. Now correctly renders "Police(2) ⚠" for mixed scenarios. Same fix applied to PDF exports and the dashboard saved-calc preview, where CBC states were rendering as "Yes".
Axle Calculator: lookup-table bridge support
FeatureDataSix states use a state-specific lookup table instead of the federal bridge formula: Alabama (non-Interstate), Vermont, Kansas, Nebraska, Montana, and Nevada. Click "per lookup table" in the threshold panel to open a draggable chart, with chips to flip between axle-count columns. The panel stays interactive on top of the truck diagram — no modal backdrop.
Axle Weight Calculator
FeatureDataNew free public tool at /axle-calculator. Run any axle layout against per-state axle weight limits, gross vehicle weight caps, the Federal Bridge Formula, and every permit class encoded for that state. Covers all 48 contiguous states, including state-specific quirks like Idaho color permits, Florida FDOT outer-bridge minimums, Maine 6-axle grandfather, New York Type 24C group balance, Ohio spacing-scaled tandem, and Vermont's lookup table.
Drag any non-steer wheel on the truck diagram to reposition it, or use the Insert axle button to drop a new one anywhere along the wheelbase. The kingpin gap auto-locks at startup so reshaping the truck does not accidentally collapse the trailer reach. The compliance ladder updates automatically as you edit, no Calculate button.
When a load fails legal limits, the permit ladder shows which annual or single-trip permit class clears it. Find it in the Resources menu in the header, in the footer, or on the Resources page.
Route Preference Slider & Road-Type Map
FeatureAfter calculating a route, you can now fine-tune which route gets picked using a slider in the Route summary bar. Drag toward "I" to accept a few extra miles in exchange for more interstate travel, or toward "NI" to minimize interstate mileage. The default leans slightly toward interstates (+5%), matching how most oversize loads prefer to run.
The route map now colors each segment by road type — Interstate (blue), US Highway (green), State Highway (orange), and Local/Other (red). Expand the Route bar to see a full mileage breakdown by road type.
Adjusting the slider re-routes and re-calculates all per-state permits automatically, and it does NOT consume a calculation credit — change preferences freely.
Address autocomplete in the Origin / Stop / Destination fields now covers full street addresses in addition to cities.
Combination Dimension Trigger Logic
FeatureWhen a load triggers escort requirements through a combination of dimensions working together (for example, width and length), the State Results table now highlights the escort count in amber and shows a "Combo triggered" tooltip on hover. Previously the count would update correctly, but there was no visual signal that the requirement came from a combined rule rather than a single dimension.
