This package covers supporting knowledge for the DVSA ADI Part 1 multiple-choice and hazard perception components. The multiple-choice paper is described by DVSA as 100 questions in 90 minutes, with 25 questions in each of four official categories, and the hazard perception component uses 14 video clips. Use the original MCQs here as a knowledge check, not as a simulation of the video clips or a full syllabus. Confirm current format, category names, pass standards and booking requirements with DVSA. Use the four study domains to organise revision, but measure yourself against the current DVSA category structure and hazard-perception rules. Practise decisions aloud, log errors by cause, and complete the scenario task before relying on MCQ scores. Confirm current test format, pass standards and booking requirements with DVSA.
Component identity and scope
The package prepares supporting knowledge for the ADI Part 1 multiple-choice and hazard perception components; it is not a full official syllabus.
The ADI Part 1 test has two distinct assessment experiences. The multiple-choice component described by DVSA presents 100 questions in 1 hour 30 minutes. The official guide states there are 25 questions in each of four categories: road procedure; traffic signs and signals, car control, pedestrians and mechanical knowledge; driving test, disabilities, and the law; publications and instructional techniques. The hazard perception component uses 14 video clips. Each clip contains at least one developing hazard, and one clip contains two.
Those mechanics matter for preparation. Multiple-choice revision needs broad, accurate knowledge and careful reading of scenarios. Hazard perception needs real-time recognition of when a situation begins to require a response, such as changing speed or direction. This guide uses four study domains—road procedure and traffic law, vehicle knowledge and safety, instructional knowledge, and hazard perception—to organise learning. Those labels are study aids; candidates should confirm the official category names and current syllabus with DVSA.
The MCQ sample in this package checks supporting knowledge. It is not a simulation of the video hazard test, and it does not reproduce official test questions. Before booking, confirm current format, identification, fees, pass standards and any accessibility arrangements with DVSA.
Prioritise preparation: breadth before polish
A diagnostic pass across all four official categories prevents over-revising familiar topics.
Start with a short diagnostic: 15–20 mixed questions and three written hazard descriptions. Mark not only right or wrong but cause: knowledge gap, misread question, slow recognition, or poor decision rule. Allocate more time to causes that repeat across topics.
Because the official guide describes 25 questions in each of four categories, do not let one strong area dominate. A candidate who enjoys road procedure may avoid mechanical knowledge, while a strong hazard scanner may neglect laws and instructional publications. Use interleaving: mix topics in each session, then revisit errors after 24–48 hours and again after a week.
Set process goals, not score promises: I can explain three reasons a wet road lengthens stopping distance, or I can state the first visible cue that turns a parked car into a developing hazard. Process goals are controllable and make revision evidence-based.
Road procedure and traffic law: read the scene before committing
Most procedure questions reward early observation, correct priority and a safe fallback.
Use a repeatable junction sequence: identify the junction type and markings; choose position; adjust speed; look for pedestrians, cyclists and emerging vehicles; decide whether the exit is clear; act smoothly. If the exit is not clear, do not enter a box junction merely because the light is green. At a zebra crossing, scan both approaches and the far side; a pedestrian waiting or already crossing should change your speed and readiness to stop.
Worked scenario: you approach a zebra crossing on a wet road. A van parked to your right blocks the view of the pavement. A pedestrian's feet are visible beneath the van, moving toward the kerb. The safe response is to reduce speed early, cover the brake if appropriate for your vehicle, and be ready to stop. Do not wait until the pedestrian steps onto the crossing. The hazard is not the parked van alone; it is the limited view plus movement suggesting someone may enter your path.
For vulnerable road users, the decision rule is space and predictability. On a narrow road, if there is not enough room to pass a cyclist with a comfortable margin, hang back. Do not squeeze past and do not sound the horn as a demand. On motorways, a red X above a lane means the lane is closed; treat it as a prohibition, not a suggestion. Common errors include assuming priority, committing to a manoeuvre before the exit is clear, and looking only at the vehicle immediately ahead rather than the whole scene.
Vehicle knowledge and safety: mechanisms and limits
Explain systems by what they do and what they cannot override—physics, friction and maintenance.
Stopping distance is thinking distance plus braking distance. Worked calculation: a car travels at 20 m/s and the driver reacts in 1 second. Thinking distance is 20 m. If braking deceleration is 8 m/s², braking distance is v²/(2a) = 400/16 = 25 m. Total stopping distance is 45 m. On a wet road, available friction is lower, so the same brake input produces less deceleration and a longer braking distance. The thinking part still depends on alertness and recognition time.
ABS is designed to prevent wheel lock during heavy braking and help the driver retain steering control. It does not repeal physics: on loose gravel or snow, a locked wheel may build a wedge that shortens stopping distance, so ABS can lengthen stopping distance on some surfaces while improving steerability. Tyre condition affects grip, water clearance and heat; checks should include visible damage, embedded objects and pressure when cold, using the vehicle manufacturer's guidance. This guide does not set a legal tread threshold; confirm legal maintenance requirements with DVSA or the relevant authority.
A catalytic converter reduces harmful exhaust emissions by promoting chemical conversion of gases, but it does not repair a rich-running engine or replace routine maintenance. Head restraints are occupant-protection devices: correct adjustment limits rearward head movement in a collision and reduces whiplash risk. Common errors include treating ABS as a guarantee, inflating tyres by feel, and confusing emissions equipment with performance tuning.
Instructional knowledge: client-centred goals and feedback
Good instruction changes the pupil's thinking and independence, not just the car's position.
A useful lesson objective is specific, observable and bounded: By the end of the lesson, the pupil can emerge from a quiet T-junction safely, using the look–decide–move routine with one prompt or fewer. Break the task into components: approach speed, observation sequence, gap judgement, clutch and gear control, and post-emergence review. Agree the goal with the pupil and check understanding before moving off.
Worked scenario: a nervous pupil freezes at a busy roundabout. A client-centred instructor does not take over every decision. First, reduce load: choose a quieter roundabout or pause before the give-way line. Ask the pupil to describe what they can see and what would make a safe gap. Provide one specific instruction at a time, then return control. After the manoeuvre, ask the pupil to self-assess before adding your observation.
Feedback is most useful when it is timely, specific and actionable. You need to be more confident is vague. On the last three approaches you looked right but not left after the give-way line; practise the left-right-left sequence before moving is usable. Common errors include over-talking, correcting every small fault at once, and praising outcomes the pupil did not control. Confidence grows through graduated challenge and evidence of progress, not empty reassurance.
Hazard perception: what counts and when to respond
A developing hazard is a situation that would make a competent driver change speed or direction; static scenery is not enough.
The official hazard-perception guide describes a developing hazard as something that would cause you to take action, such as changing speed or direction. A parked car doing nothing is not developing. When its right indicator starts to flash and it begins to move away, it becomes developing because you may need to slow down. The test gives up to 5 points per developing hazard; high scores depend on early recognition. Continuous or patterned clicking does not score.
Scanning should be active and staged: far ahead, middle distance, near field, mirrors and side roads. Look between parked vehicles, at brake lights and indicators, at wheel movement, and at drivers' head position. In a two-hazard clip, do not stop after the first hazard; reset your scan. Worked clip narrative: a pedestrian walks along the pavement parallel to your path. That alone is not developing. When they turn toward the kerb, pause, then step into the road, the hazard develops. The best response is the earliest moment their movement would require you to adjust speed or direction—not the moment they are already in front of you.
This package's MCQs test supporting knowledge. They do not simulate timing, video or scoring. For open-task practice, watch a road scene or describe a remembered one and write three lines: what was static, what cue changed, and what action you would take. Repeat until the cue-action link is quick and calm. Common errors include clicking at every parked car, waiting for the hazard to become obvious, and ignoring the second hazard in a dual-hazard clip.
Integrated practice task and self-check rubric
Combine wet-road procedure, a vulnerable road user and a learner-focused review in one 30-minute task.
Task: You are teaching a pupil on a wet urban road. Ahead is a zebra crossing with a van parked on the right, a cyclist signalling left, and a side road on your left. The pupil is anxious and has previously missed pedestrians at crossings. In 10 minutes, write a lesson plan with: two observable goals; the observation sequence you will coach; one phrase of specific feedback you would give after the pupil slows early for a hidden pedestrian; one fallback if the pupil becomes overloaded; and how you would use the cyclist as a scanning cue without creating a second task overload. Then write a 100-word hazard-perception description of the moment risk begins to build.
Self-check rubric: 1. Priority: Did the plan keep the pedestrian and cyclist safe before discussing smoothness? 2. Observation: Did it include far, near and side-road scanning rather than only the car ahead? 3. Instruction: Were goals specific, measurable and agreed with the pupil? 4. Feedback: Was it timely, behavioural and limited to one or two points? 5. Hazard timing: Did the description identify the cue that changed a static scene into a developing hazard? 6. Limits: Did the plan avoid claiming ABS, experience or confidence can cancel wet-road physics? Score each 0–2; below 9/12 means revisit the weak section before timed practice.
Use the same rubric on your MCQ errors. A wrong answer caused by not reading first or safest is a comprehension issue; a wrong answer about braking, priority or feedback is a knowledge issue. Log the cause, not just the topic.
A practical study sequence
A six-week rhythm works when each week mixes knowledge, scenario writing and review.
Week 1: diagnostic and road procedure. Read a junction sequence aloud, then answer mixed questions. Week 2: vehicle systems and calculations. Build a one-page sheet on stopping distance, ABS, tyres, emissions and head restraints. Week 3: instructional knowledge. Write lesson objectives for three common faults and practise giving one-sentence feedback. Week 4: hazard perception. Use written clip descriptions daily; focus on cue-to-action timing and dual-hazard resets. Week 5: integrated practice. Complete the task above under mild time pressure, then mark with the rubric. Week 6: mixed review. Reattempt only errors from your log, plus a short timed set across all four official categories.
Each session should end with retrieval: close the notes and explain three rules or mechanisms in your own words. Keep a two-column error log—what I chose and why the safer answer is safer. Schedule review after 24–48 hours and again after a week. Stop relying on recognition of a page; practise producing the reason. If a current rule, format detail or legal threshold matters for your booking, check it with DVSA rather than a forum or a recollection.
