Pennsylvania is structurally useful but flagged for review because one official
law source uses legis.state.pa.us, a non-standard state domain. The source is
kept in the registry with a note so the audit can surface it rather than hide it.
How to verify this yourself
Open Title 75 Chapter 49 for statutory weight language. Use the pa.gov PennDOT
hauling permit service page for permit application steps. If reviewing a ticket,
compare the citation to the current Title 75 language.
FAQ Why is Pennsylvania medium confidence? The Pennsylvania law source is official but uses a non-.gov domain, so it is listed as a non-standard official-domain warning.
Where are PennDOT hauling permits handled? Use the official pa.gov PennDOT hauling permit service page.
Is a Pennsylvania fine amount fully calculated here? No. The page points to official law sources and leaves exact citation-specific calculation to the current statute and court record.
