Source Registry
Review the official and high-confidence source registry that backs every indexable compliance guide on Trucking Checklist.
The source registry lists every official or high-confidence source used across Trucking Checklist. Each entry carries the publisher name, document title, URL, source type, and confidence level. A guide page cannot appear in the sitemap or search index unless at least one of its registered sources is an accepted official source — no official source means no public page.
Accepted source types. The registry accepts three categories: federal government publications (eCFR, FMCSA, IRS, DOT), state government publications (state DMVs, departments of revenue, departments of transportation, and IFTA base-jurisdiction offices), and official program organizations recognized as administering a compliance program (IFTA Inc., IRP Inc., and the UCR Plan). Secondary sources — news articles, trade publications, law firm summaries, and aggregator portals — are not accepted as standalone support for an indexable page. They may be consulted for context during research but are not listed in the registry.
Confidence levels. Each source carries a confidence designation of high or medium. High-confidence sources are primary official publications — the actual federal register text, eCFR, or the authoritative state agency page for a specific program. Medium-confidence sources are official agency pages that cover the relevant program but are less direct — such as a state DMV landing page that links to the applicable form rather than publishing the requirement text itself. Source confidence is used to set the confidence indicator on each guide page. A page with any medium- or low-confidence source is marked medium confidence regardless of other sources.
How stale sources are handled. When an official agency URL goes dead, the affected page is flagged and the broken source is marked inactive. The page is removed from the sitemap until a confirmed replacement official source is located, reviewed, and registered. Secondary sources and archived copies are not accepted as replacements. Once a verified replacement is registered, the page is re-reviewed against the new source before re-entering the index.
Source count, publisher breakdown, and coverage gaps are tracked in the site's internal data quality report. Gaps — programs where no federal or state source is registered — result in those pages being excluded from the index until a qualifying source is added. The source registry shown here reflects the current registered set as of the last-reviewed date on this page.

FAQ
Are sources invented?
No. Every entry in the source registry is a real official publication at a verifiable agency URL. Sources that cannot be verified against a live official URL are not registered.
Can secondary sources support an indexable page alone?
No. Indexable pages require at least one federal government, state government, or official program organization source. Trade publications, news articles, law firm summaries, and third-party compliance portals are not accepted as standalone official sources.
What does 'medium confidence' mean for a source?
Medium-confidence sources are official agency pages that cover the relevant topic but are one step removed from the primary regulatory text — such as a state DMV landing page that links to the relevant form rather than publishing the regulation itself. A page with any medium-confidence source is shown as medium confidence overall.
What happens when a source becomes stale or a URL goes dead?
The affected page is removed from the sitemap and the source is marked inactive. The page stays out of the index until a confirmed replacement official source is located, reviewed, and registered. Secondary sources and web archives do not qualify as replacements.
