How Layna checks its guidance.
Layna turns official learner-driver information into practical tools. Accuracy, visible sourcing and useful explanations are part of how every guide is made.
Be clear about where a rule applies
Our current car curriculum covers England, Scotland and Wales. Test requirements are not labelled as applying throughout the UK when Northern Ireland has a different system. Local limits, signs and vehicle-specific controls still matter. Read our UK coverage.
Official sources first
Rules, pass marks, test formats and vehicle-safety questions are checked against the relevant GOV.UK or DVSA page. References are collected here so lessons and quizzes can stay focused on learning. Rule references and review records are retained with the content.
Clear authorship
Guides identify the Layna editorial team as author and Layna as publisher. When a specialist contributes to or reviews a piece of work, that contribution is credited on the page.
Facts and teaching are kept distinct
Official requirements are presented as sourced facts. Mnemonics, practice questions, readiness checks and planning frameworks are labelled as Layna guidance so learners can see what comes from the official source and what Layna has created to help them practise.
Review dates mean a real check
A checked date changes only after the page and its source have been reviewed. Pages are checked during the annual year change, on a regular review cycle, or sooner when official guidance changes.
Original tools with a clear purpose
Layna’s questions, diagrams and explanations are original unless a licence is stated. Interactive tools are designed for revision and reflection between lessons, alongside safe instruction and official DVSA material.
Commercial independence
Paid plans do not change an editorial answer, source or safety explanation. Any sponsorship, affiliate relationship or paid placement that could affect how a page is understood will be clearly labelled.
Corrections
If something appears wrong or unclear, email hello@layna.app with the page and issue. Material corrections are checked against the official source before publishing.
