FAQ
What is the difference between a guide and a state hub?
State hubs are the canonical money pages for rules, fees, and stations. Guides add narrative depth, national comparisons, and how-tos, and should link back to hubs.
Are change logs kept up to date?
State inspection-changes guides are dated when we record official updates. Always prefer the live .gov program page if dates conflict.
Do guides replace the checklist?
No. Use the safety-inspection checklist pillar for system-by-system prep; guides explain scenarios and fails in more depth.
Which guide should new residents read first?
Start with the requirement quiz, the out-of-state transfer pillar, then your destination state requirements guide and hub.
Can I suggest a guide topic?
Yes — use Contact. We prioritize topics tied to official statute or program changes.
