Editorial policy
How lessons, questions and advice on this site are written, checked, reviewed and corrected.
Who writes this site
All lessons, questions and explanations are written in-house by the TheoryTestAdvice editorial team and checked against current official guidance before publication. Every substantive page shows its author, its last-checked date and the sources used.
Independent review by an approved driving instructor (ADI) is planned. Until an ADI is appointed, no page on this site claims instructor endorsement, and we do not describe in-house checking as independent review.
Source hierarchy
Where sources disagree, the higher tier wins.
| Tier | Source | Used for |
|---|---|---|
| 1 | GOV.UK and DVSA | Test format, fees, booking, identification, accessibility arrangements |
| 2 | The Highway Code | Rules, must/should distinctions, road-user hierarchy |
| 3 | Know Your Traffic Signs | Sign meanings, categories and markings |
| 4 | Official legislation | Legal requirements where the Highway Code says “MUST” |
| 5 | NHS and recognised first-aid bodies | First aid, CPR, defibrillator guidance |
| 6 | Other authoritative transport sources | Context and background |
| 7 | Original explanation | Teaching, worked scenarios, memory cues |
How a question is written
Every question in the bank must satisfy all of the following before it is published.
- Original wording. Not copied or lightly reworded from the official revision bank.
- Realistic distractors. Wrong answers reflect mistakes learners actually make — confusing “should” with “must”, applying a dry-weather rule in the wet, misreading a sign shape, acting too late, watching the wrong road user. Absurd options teach nothing.
- A real explanation. It must say what the correct action is, which road clue identifies it, why the tempting wrong answer is unsafe, and where you will meet this again.
- A traceable source. At least one tier 1–5 reference.
- Recorded metadata. Topic, subtopic, difficulty, cognitive skill, author, reviewer, review date and version.
We never show only “Correct” or “Incorrect”. If a question cannot be given a useful explanation, it does not belong in the bank.
Language rules
We do not use claims we cannot support.
Never used
- “Guaranteed pass”
- “Beat the test”
- “Secret DVSA questions”
- “Official test questions”
- “Pass instantly”
Used instead
- “Build your readiness”
- “Understand why”
- “Practise your weaker topics”
- “Prepare at your own pace”
- “Based on current UK road guidance”
We also never present a single percentage as a readiness score. Readiness is described in sentences, with the evidence behind it, because one number invites false confidence.
Review schedule
Monthly
Booking rules, fees, identification requirements, accessibility arrangements, test format and official announcements.
Quarterly
High-traffic lessons, mock-test explanations, legal topics, motorway guidance and hazard-perception guidance.
Annually
The complete curriculum, end to end.
Immediately
Whenever the Highway Code changes, the law changes, DVSA publishes a test update, a factual complaint is received, or we discover an error ourselves.
Corrections
When we change something substantive, we record it in the public updates log with the date, what changed, why, the source and the new version number. We do not quietly edit and move on.
Advertising and independence
Advertising and any future commercial partnership is disclosed clearly and never influences the accuracy of training material. No advertiser reviews, approves or sees content before publication. If we ever earn commission from a link, the page will say so on the page itself.
Artificial intelligence
Where drafting tools are used to help produce content, the output is checked against the source hierarchy above by a person before publication, and that person is named as the author. We do not publish unchecked generated content, and no page is published without a source.
