Fact-check policy

Source hierarchy

Tier 1: official legal and regulatory sources

Primary laws, regulator portals, and official handbooks are mandatory anchors for rule claims.

Tier 2: official operational guidance

Traffic advisories and formal driving guidance are used to add practical interpretation.

Tier 3: supporting references

Secondary references can clarify terminology but cannot override official statements.

Review cadence

High-impact pages are rechecked monthly, and all pages are reviewed at least once per quarter.
