UK Driving Theory Test Study Guide - Highway Code
The Driving Theory Test, administered by the Driver and Vehicle Standards Agency (DVSA), is required before you can book a practical driving test in Great Britain. The theory test has two parts taken in one sitting: a multiple-choice section sourced from The Highway Code, and a hazard perception section using video clips. This guide covers the Highway Code material that the multiple-choice section is built from, plus the strategy for both halves.

What the theory test covers
Every multiple-choice question is sourced from The Highway Code (an official GOV.UK publication that is updated regularly), 'Know Your Traffic Signs', and 'The Official DVSA Guide to Driving - the essential skills'. There are no surprise topics - the depth of the questions is what makes the test challenging.[1][2][3]
| Section | Items | Pass mark |
|---|---|---|
| Multiple choice | 50 questions | 43 of 50 (86%) |
| Hazard perception | 14 video clips, 15 hazards total | 44 of 75 |
The Highway Code - what to memorise
The Highway Code is divided into 18 sections covering different road users. The DVSA test draws roughly proportionally from each, so allocate study time accordingly.
- Rules for pedestrians, cyclists, animals, motorcyclists, and drivers - each group has a section.
- General rules, techniques, and advice for all drivers and riders - by far the largest section, covering signals, speed limits, lane discipline, lighting, and parking.
- Using the road - overtaking, road junctions, roundabouts, pedestrian crossings, reversing.
- Road users requiring extra care - children, older or disabled pedestrians, learner and inexperienced drivers.
- Driving in adverse weather - wet weather, ice and snow, fog, hot weather.
- Waiting and parking, motorways, breakdowns and incidents.
- Road works, level crossings, tramways.
- Light signals controlling traffic, signals to other road users, signals by authorised persons, traffic signs, road markings.
- Vehicle markings (e.g. ADR hazard panels for dangerous goods).
- Annexes - first aid, vehicle maintenance, vehicle security, penalties.
Sign families and their shapes
| Family | Shape | Examples |
|---|---|---|
| Mandatory orders (must do) | Blue circle | Turn left ahead, mini-roundabout, route for buses |
| Prohibitory orders (must not do) | Red circle | No entry, no overtaking, speed limit, no waiting |
| Warnings | Red triangle (point up) | Bend ahead, school, slippery road, low bridge |
| Direction signs (primary route) | Green rectangle | Distance to towns on main routes |
| Direction signs (motorway) | Blue rectangle with white text | Junction numbers, services |
| Direction signs (non-primary) | White rectangle with black text | Local destinations |
| Information | Black-on-white | Hospital, viewpoint, public telephone |
| Tourist | Brown background | Heritage sites, attractions |
UK speed limits and stopping distances
| Road type | Cars/light vans | Vans (3.5t+) | HGV |
|---|---|---|---|
| Built-up area (street lights) | 30 mph | 30 mph | 30 mph |
| Single carriageway | 60 mph | 50 mph | 50 mph |
| Dual carriageway | 70 mph | 60 mph | 60 mph |
| Motorway | 70 mph | 70 mph | 60 mph |
- Stopping distance at 20 mph: ~12m total (6m thinking + 6m braking).
- Stopping distance at 30 mph: ~23m total.
- Stopping distance at 50 mph: ~53m total.
- Stopping distance at 70 mph: ~96m total - almost the length of a football pitch.
- Wet roads: at least double dry distances.
- Icy conditions: up to 10× longer.
Motorway-specific rules
- Learners are allowed on motorways since June 2018, but only with an approved driving instructor in a dual-control vehicle.
- Lane discipline - keep to the left except when overtaking. The right-hand lane is not a 'fast lane' - it is the overtaking lane.
- Smart motorways with all lanes running (ALR) - when the hard shoulder becomes a running lane, gantry signs above the lane indicate live use; a red X means the lane is closed and must not be used.
- Speed limits on motorways - base 70 mph, but variable speed limits on smart motorways are mandatory and enforced by camera.
- If you break down, leave the motorway via the next slip road if possible. If you cannot, use an emergency refuge area, stop on the hard shoulder, and walk to a roadside emergency phone.
Hazard perception - strategy
The hazard perception test plays 14 short clips from a driver's viewpoint. Most clips contain one developing hazard worth up to 5 points; one clip contains two hazards. You score by clicking when a hazard begins to develop - too early or too late and the score drops to zero.
- A 'developing hazard' is something that would cause you to slow, stop, or change course.
- Click as soon as the hazard becomes visible AND has begun to develop - not when it is already obvious.
- Do not click rapidly or repeatedly - the system will score you 0 for that clip if it detects a click pattern (anti-cheat).
- One click + a confirming click 1-2 seconds later is the recommended pattern.
A 14-day study plan
- Day 1: Read the introduction and 'Rules for pedestrians' chapter of the Highway Code.
- Day 2: Rules for cyclists and animals; the new hierarchy of road users.
- Day 3: General rules, techniques, advice for all drivers and riders (this is the largest chapter - split into 2 sessions).
- Day 4: Using the road - overtaking, junctions, roundabouts, pedestrian crossings.
- Day 5: Road users requiring extra care + driving in adverse weather.
- Day 6: Waiting and parking + motorway driving.
- Day 7: Take a full multiple-choice mock test in the reviewer.
- Day 8: Light signals, signs, and road markings - drill until you can identify each from shape/colour alone.
- Day 9: Hazard perception practice - 14 clips. Note which hazard types you missed.
- Day 10: Repeat hazard perception clips with focus on early-warning signs (parked cars, pedestrians at the kerb, vehicles emerging from side streets).
- Day 11: First aid and incident response chapter.
- Day 12: Second multiple-choice mock test, timed.
- Day 13: Review every wrong answer; re-read the relevant Highway Code section.
- Day 14: Light revision; bring your provisional licence and book confirmation to the test centre.

Frequently asked questions
What is the pass mark for the Theory Test?
You need at least 43 of 50 multiple-choice questions correct (86%) AND at least 44 of 75 on the hazard perception section. You must pass both parts in the same sitting; failing one means re-taking the entire test.
Where do I take the DVSA Theory Test?
At a DVSA-approved theory test centre. Booking is done through GOV.UK. You must bring your provisional driving licence (photo card) - without it you will not be allowed to take the test.
How long is the theory test pass valid?
Two years. If you don't pass the practical driving test within two years of passing the theory, your theory pass expires and you must retake the theory test before you can book another practical attempt.
How much does the Theory Test cost?
£23 for cars and motorcycles (as of 2024). Always check gov.uk/book-theory-test for the current fee - the fee is non-refundable if you fail.
Can I take the test in a language other than English?
No. As of April 2014, the theory test is only available in English and Welsh, with English subtitles for the hazard perception clips. Voiceovers in other languages were removed; interpreters are also not allowed.
What's the youngest I can take the theory test?
You can take the car theory test on or after your 17th birthday (16th birthday if you receive certain disability allowances). You must hold a valid provisional driving licence at the time of booking and on test day.
