Who maintains this
TruckWeightInfo.com is maintained by Marcus Webb, a transportation compliance researcher who has spent years working directly with U.S. truck weight regulations — FHWA bridge formula publications, state DOT permit portals, state statute databases, and enforcement agency materials. The research comes from firsthand engagement with the documentation that drivers, fleet safety managers, and dispatchers actually need to find quickly.
The editorial role is intentionally narrow: locate the controlling official source, record what it supports, and keep the distinction between confirmed language and interpretation visible on the page. This site does not sell permits, broker freight, estimate citation outcomes, or route trucks. That separation is deliberate — a reference tool is only useful when it is clear about where the agency source ends and where the operating decision begins.
The motivation behind the project was practical. Federal and state weight data is publicly available, but finding the authoritative agency page for a specific state, route class, or axle configuration — and then verifying whether a third-party summary actually reflects the current statute — takes time that dispatchers and safety managers rarely have. This site removes that search step by recording the source URL, publisher, and verification date for every populated data field.
Editorial standards
Every state page is built field by field from official agency sources: state DOT permit pages, published statutes, FHWA or FMCSA publications. Sources are assigned a confidence label:
- High — the official source directly states the value.
- Medium — the value is officially sourced but requires interpretation.
- Low — no specific official source was confirmed during review.
Fields that cannot be confirmed from an official source are marked not found in official review rather than filled with a guess or a third-party summary. State pages below the quality threshold are withheld from search indexing until source coverage meets the standard.
Each published state field keeps its source trail visible on the page: source id, publisher, last verification date, status label, and confidence label. When a state uses a non-.gov but officially recognized permit system, the domain is noted rather than hidden. When a field is citation-specific or not confirmed in the reviewed material, the page says so plainly instead of filling the gap with a third-party estimate.
See the methodology page for the full criteria, the editorial policy for publication and correction standards, and the sources registry for every official source used across this site: 144 sources across federal, state DOT, permit office, and enforcement categories.
Review workflow
A review pass starts with the state DOT or permit office, then moves to statutes, administrative code, enforcement pages, FHWA publications, and FMCSA materials as needed. The reviewed value is written only after the source can be attached to a field. If the source supports the field only indirectly, the field remains medium confidence. If the source cannot be confirmed, the page keeps the gap visible and may stay out of the sitemap until the coverage improves.
Corrections are handled the same way. A suggested change is not accepted because it sounds plausible; it must point to a current official URL, statute section, permit-office notice, or agency document that supports the replacement wording.
Why it exists
Overweight violations are among the most common commercial vehicle enforcement actions in the U.S. The fine structures, permit processes, and bridge-formula implications are consequential — but the official documentation is spread across dozens of agency websites with inconsistent formats. This site is an attempt to make the primary source findable in one place, with honest labels about what is confirmed and what is not.
Contact and corrections
To report a broken source link, a field value that conflicts with the current agency page, or a privacy question, use the contact page. Source corrections that can be verified against an official URL are processed in the next review cycle.
What this site is not
TruckWeightInfo.com is a reference site, not a legal service. Nothing here constitutes legal advice. Official sources, permit conditions, enforcement interpretations, and fine schedules change — always verify the linked official source before making an operating decision. If a source link appears broken or outdated, the agency page is controlling.
