Rule claims are based primarily on current Queensland RTA and NSW Government or Fair Trading materials. Third-party explanations may help identify issues but do not replace primary verification.
Deterministic calculations
The calculator does not ask an AI model to select a legal rule. User answers select versioned rule data, and code performs the date arithmetic.
Review and update dates
Supported rules include a source and last-verified date. Material corrections are recorded on the Sources and updates page.
Limits and uncertainty
Unsupported, ambiguous or fact-dependent pathways are labelled for an official check. Content distinguishes calculation assistance from legal advice.
Advertising independence
Future advertising, affiliate or sponsorship arrangements will not determine calculator outcomes or alter the interpretation of cited sources. Paid placement will be identified.
Corrections
Send correction requests to [email protected] with the affected URL and supporting official source. Substantiated material errors should be corrected promptly and reflected in the update record.
