Who maintains this
TruckWeightInfo.com is maintained by an independent research team focused on official-source traceability for U.S. truck weight compliance.
The motivation was straightforward: official federal and state weight data is publicly available through FHWA, state DOT permit offices, and statute portals. The problem is not access — it is that finding the right page for the right route and vehicle configuration, and verifying whether a third-party summary is current, can take time that drivers and safety managers often do not have. This site structures those official sources into a consistent, source-labeled reference.
Why it exists
TruckWeightInfo.com organizes official sources by state and topic, labels the confidence level of each data field, and links directly to the primary agency or statute rather than summarizing from a summary. Every populated field points to a source, a verification date, and an honest confidence label. Fields that could not be confirmed from an official source are marked accordingly rather than filled with a guess.
How information is sourced
Each state page and article links to an official source: a state DOT permit page, a published statute, an FHWA or FMCSA publication. Fields are labeled high, medium, or low confidence based on how directly the value can be tied to that source.
See the methodology page for the full criteria used to assign confidence labels and indexability scores, and the sources page for the complete list of official sources used across this site.
What this site is not
TruckWeightInfo.com is a reference site, not a legal service. Nothing on this site is legal advice. Official sources, permit conditions, and enforcement practices change — always verify the linked official source before making an operating decision.
