How we review Library information

Sources, review dates, English/Spanish scope and how to suggest a correction.

The Library is informative and illustrative. Available evidence can change. Use each page alongside your own investigation, the vehicle's actual documents and current official guidance.

Which sources we use

For a factual review, we prefer the relevant primary material: government agencies and current legal text for state procedures, manufacturer documents for vehicle specifications and model announcements, and the original publication for historical reporting. A useful source must support the particular statement, market and time period being described.

A link alone does not establish that a claim is correct. A source can be incomplete, inaccessible, outdated or in conflict with another source. Review outcomes can include supported information, narrower wording, an explicit uncertainty or a withheld amount or instruction.

What the dates mean

• Source checkpoint: the recorded date associated with the state, model or article data. Its scope matters; it is not a promise that every statement is current today.
• Selected claims checked: a later, limited review of the indicated subject. It does not refresh the entire state or model record.
• Content modification: an edit to the page. Rebuilding the website is separate from checking the underlying facts.

When a review date is not documented, the page says so. Fees, eligibility conditions, manufacturer information and historical findings should be checked against the linked current sources before a decision.

English and Spanish

A scoped text change is reviewed in both languages for the same conditions, exceptions, dates and level of certainty. Original agency names, document titles and statutory identifiers may remain in their original language. Consult the original source when exact wording matters.

Vehicle names, history and illustrations

A global reveal date, a US model year and the history of a predecessor can describe different events. Keep those meanings separate when reading a model history. Photographs are illustrative; confirm the actual vehicle's market, year, trim and equipment.

Updates and corrections

A review covers its recorded scope and available evidence. New laws, agency fee pages, manufacturer releases, broken source links and reader reports can trigger another review. Some uncertainties remain in the continuing review queue.

Use Report a correction beside the information notice to open Contact with the public page and language already included. Describe the statement, the suggested correction and a public primary-source link when available. Opening that draft does not send a message; you choose what to submit. Avoid including private vehicle or account documents.

This explanation is a review method, not certification, legal advice or a guarantee that the information replaces your investigation.
