Car theory test revision,
one topic at a time.
Revise the Highway Code with 21 short topic lessons and 315 original Layna questions. Learn road signs, practise without a timer, then take a 50-question multiple-choice mock. Review both the answers you missed and those you guessed before choosing what to study next.
Car learners in England, Scotland and Wales. About our UK coverage.
Questions are written by Layna, not licensed DVSA test questions.
A useful order for revision
- Learn a topic. Understand the rule and why it exists before answering questions.
- Practise without the clock. Read the explanation even when you answer correctly.
- Check your knowledge under time pressure. Take a mock, flag uncertain answers and revisit weak topics.
A high mock score is useful feedback, not a guarantee. The real theory test has two parts; you also need to prepare separately for hazard perception.
Ready for a mock?
The multiple-choice practice has 50 questions and a 57-minute timer, with a review after you finish.

Alertness
Safe driving starts before the car moves. Tiredness, alcohol, drugs, medicines and distractions all reduce the time you have to make a sound decision.
Try the free lessonHazard awareness
A hazard is easier to handle when you notice the clue early. Look well ahead, scan the pavements and side roads, and ask what could change next.
Study with PlusIncidents
After a breakdown or collision, your first job is to prevent further harm. Stop safely, warn others without putting yourself at risk and share the required information.
Study with PlusJunctions
Junctions combine position, speed, observation and priority. Slow early enough to see, be seen and stop before you commit.
Study with PlusMotorways
Motorway driving depends on observation, lane discipline and early decisions. Build speed on the slip road, keep left unless overtaking and never reverse or stop except in an emergency.
Study with PlusOther road users
Buses, horse-drawn vehicles, mobility scooters and slow-moving traffic need different amounts of time and space. Read their limitations before you pass or turn.
Study with PlusOther vehicles
Large vehicles need more room to turn and stop, and their drivers have larger blind spots. Stay where the driver can see you and avoid squeezing into disappearing gaps.
Study with PlusPedestrian crossings
Crossing types use different signals, but the safe approach is consistent: slow down, keep the crossing clear and give people time to finish.
Study with PlusRail crossings
A railway crossing is one place where waiting in the wrong position can be fatal. Obey lights and barriers, cross without stopping and know how to escape if the vehicle fails.
Study with PlusRoad markings
Lines, boxes, arrows and words organise where you may drive, wait or turn. Read them early so the final move is small and predictable.
Study with PlusRoad procedure
Mirrors, signals, position, speed and a final look form the backbone of everyday driving. Use the routine flexibly whenever you change direction, lane or speed.
Study with PlusSafety margins
A safe gap buys time to see, think and stop. Increase it whenever grip, visibility, speed or the behaviour ahead makes the normal margin less reliable.
Study with PlusSignals
Signals tell you about intention or control, but they do not make a manoeuvre safe. Obey authorised signals and treat another road user’s signal as information to check.
Study with PlusSpeed limits
A speed limit is the maximum in suitable conditions. The safe speed may be lower because of people, bends, surfaces, traffic or visibility.
Study with PlusTowing
A trailer changes the vehicle’s length, acceleration, braking and response to wind. Match it correctly, secure the load and drive within the lower limits.
Study with PlusVehicle handling
Smooth inputs protect tyre grip. Look ahead, select the right speed before a bend or slope and know how the car’s safety systems respond.
Study with PlusVehicle safety
Tyres, lights, glass, brakes, fluid and secure loads affect every decision after you move. A short check prevents predictable failures.
Study with PlusVisibility
Fog, darkness, glare, spray and dirty glass shrink the usable road ahead. Improve the view, make the car visible and reduce speed before the view disappears.
Study with PlusVulnerable road users
People walking, cycling, riding horses or motorcycles have less protection than people in cars. Reduce the danger your vehicle creates, especially when turning or overtaking.
Study with PlusWaiting and parking
A legal space can still be unsafe. Check restrictions, sight lines, access and the effect on pedestrians and cyclists before you leave the car.
Study with PlusWeather
Rain, ice, snow, heat and wind change what the car and other road users can do. Slow earlier, increase space and avoid sudden control inputs.
Study with PlusKeep the essentials close.
Road signs
Recognise the artwork, learn its meaning and repeat the signs that need another look.
Pass marks and format
Understand the separate scores required for multiple-choice questions and hazard perception.
A short revision plan
Organise limited revision time around gaps in your knowledge, not a promise to pass in three days.
What about hazard perception?
It is a separate part of the real theory test. Layna’s hazard-perception guide explains developing hazards and the scoring format. The full video practice course is not part of this revision course yet; a multiple-choice score alone cannot show readiness for both parts.

Questions about car theory revision
How should I revise for the UK car theory test?
Learn a topic and its rules, practise questions without a timer, then review why each answer is right or wrong. Use a timed multiple-choice mock to find weak topics rather than only repeating familiar answers. Revise signs alongside the situations where you meet them. Prepare for hazard perception separately: multiple-choice practice covers only one part of the real theory test.
Does Layna use official DVSA theory questions?
No. The questions are original Layna practice questions based on the Highway Code, with explanations. They are not licensed DVSA revision questions or a copy of the live test. Learning the rule is more useful than memorising which answer position was correct.
Can I take a full theory test in Layna?
Layna has timed 50-question multiple-choice mocks with a 57-minute timer and an answer review. These are not a complete two-part theory test: the real test also includes video-based multiple-choice questions and a separate hazard-perception section. Layna’s hazard-perception video course is not available yet.
What should I revise after failing a theory test?
Use your result to identify which part needs work. For multiple choice, separate rules you did not understand from questions you misread and correct answers you guessed. Revisit those topics before another mock. If hazard perception was the problem, practise developing-hazard recognition with suitable videos; another multiple-choice paper does not address that gap.
