Source order
State DOT, state permit office, state law, state enforcement agency, FHWA, and FMCSA sources are preferred. Private summaries are not used to fill factual state fields.
Confidence
High means the official source directly supports the field. Medium means the source is official but the field needs interpretation. Low means a specific official source was not confirmed.
Status
Statuses distinguish confirmed fields, inferred fields, fields not found in official review, no statewide rule confirmed, not applicable, needs review, and todo.
Needs review and indexability
All state pages can be visited, but not every page is treated as ready for search indexing. A page marked Needs review has one or more fields where official-source support is still thin, usually fine/enforcement detail or seasonal restrictions. That label does not mean every field on the page is wrong; it means readers should pay close attention to the confidence and status shown beside each field.
Pages below the quality gate receive noindex,follow and stay out of the sitemap until source coverage improves. The quality gate is not lowered to make a page indexable, and uncertain fields are not filled from unofficial summaries.
Why some fields stay low confidence
Some states publish permit pages clearly but keep fine schedules in statutes that require citation-specific reading. Seasonal restrictions may also be route-specific, temporary, or local rather than statewide. Fields that cannot be confirmed from an official source remain low confidence and explain the review scope rather than presenting a guess.
