Sample UK LGV/HGV Hazard Perception Practice Questions

Try these sample questions to test your UK LGV/HGV Hazard Perception exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1In LGV hazard perception practice, which situation has become a developing hazard?

A.A parked car is stationary with no signal showing

B.A side road is visible but no vehicle is emerging

C.A parked van signals and starts to move out into your lane

D.A low bridge warning sign is passed on an alternative route

Explanation: A developing hazard is one that has started to require action from you, such as slowing, changing position, or preparing to stop. The van is no longer just something to monitor once it signals and begins moving into the path of a large goods vehicle.

2What best distinguishes a potential hazard from a developing hazard in the official scoring concept?

A.A potential hazard is outside towns, while a developing hazard is always in a town

B.A potential hazard needs monitoring, while a developing hazard is starting to require a driving response

C.A potential hazard always involves another driver breaking the law

D.A developing hazard is only something directly in the centre of your lane

Explanation: Potential hazards are clues that may change, such as parked vehicles, junctions, or pedestrians near the kerb. They become developing hazards when their movement or behaviour means you should act to maintain safety.

3During the official Driver CPC part 1b video test, when should you respond to a developing hazard?

A.As soon as you recognise the hazard is starting to develop

B.Only after you would need to make an emergency stop

C.At regular intervals throughout every clip

D.Only when the hazard is directly touching your vehicle

Explanation: The scoring window rewards early recognition once the hazard starts to develop. Waiting until the situation is critical is late, and patterned clicking can cause you to score nothing for that clip.

4How many video clips are in the official LGV/HGV Driver CPC part 1b hazard perception test?

A.14 clips

B.16 clips

C.19 clips

D.25 clips

Explanation: GOV.UK describes Driver CPC part 1b as 19 hazard perception clips. One of those clips contains two developing hazards, so there are 20 scoreable hazards in total.

5How many scoreable developing hazards are in the official LGV/HGV Driver CPC part 1b test?

A.19, because every clip has exactly one hazard

B.20, because one of the 19 clips contains two developing hazards

C.75, because each clip can have several hazards

D.100, because every possible hazard is scored

Explanation: The official test has 19 clips and 20 scoreable developing hazards. One clip has two developing hazards, so you must keep scanning after the first hazard in every clip.

6What is the official pass mark for Driver CPC part 1b hazard perception?

A.44 out of 75

B.57 out of 75

C.67 out of 100

D.85 out of 100

Explanation: The LGV/HGV Driver CPC part 1b hazard perception pass mark is 67 out of 100. Part 1a multiple-choice is separate and has its own pass mark of 85 out of 100.

7How many points can each scoreable developing hazard be worth in Driver CPC part 1b?

A.Up to 2 points

B.Up to 5 points

C.Exactly 10 points

D.A fixed pass or fail only

Explanation: Each developing hazard can score up to 5 points. The earlier you correctly respond within the scoring window, the higher the score for that hazard.

8What can happen if you click continuously or in a clear pattern during a hazard perception clip?

A.You automatically get the maximum score for the clip

B.The clip may score nothing even if a real hazard appeared

C.Only your first click is ignored and all later clicks count normally

D.The system adds a penalty to your part 1a multiple-choice score

Explanation: GOV.UK warns that you will not score if you click continuously or in a pattern. Good practice is to respond to genuine developing hazards, not to try to game the scoring window.

9Why should you treat each official hazard perception clip as a one-time observation task?

A.You can review each clip only if you fail the first time

B.You can replay the clip after answering part 1a

C.You get only one attempt at each clip and cannot review or change responses

D.You can pause the clip to inspect mirrors and signs

Explanation: The official hazard perception clips are not reviewable. You need to keep scanning throughout the moving scene and respond when a genuine hazard develops.

10What is the correct part 1a context for LGV/HGV Driver CPC candidates?

A.50 questions in 57 minutes with a 43 out of 50 pass mark

B.100 questions in 1 hour 55 minutes with an 85 out of 100 pass mark

C.7 case studies in 1 hour 15 minutes with a 40 out of 50 pass mark

D.19 video clips with a 67 out of 100 pass mark

Explanation: Driver CPC part 1a is the multiple-choice theory test: 100 questions, 1 hour 55 minutes, and 85 out of 100 to pass. Part 1b is the separate hazard perception video test.

About the UK LGV/HGV Hazard Perception Exam

The UK LGV/HGV Driver CPC Part 1b Hazard Perception Test is the DVSA video-based hazard perception test for lorry and other large-goods-vehicle candidates in Great Britain. It is part of Driver CPC part 1 theory, alongside the separate part 1a multiple-choice test. The official test uses 19 interactive video clips with 20 scoreable developing hazards and a pass mark of 67 out of 100. These MCQs are original scenario and concept questions that teach professional goods-vehicle hazard recognition, large-vehicle scanning, mirrors, blind spots, vulnerable road users, braking distance, load stability, route restrictions, adverse weather, motorway hazards and official scoring concepts. They supplement preparation, but they cannot replicate or replace the official interactive DVSA video clips.

Assessment

Driver CPC part 1b is the separate hazard perception part of the part 1 theory test. Candidates watch 19 video clips showing everyday road scenes. The clips contain 20 scoreable developing hazards in total because one clip contains 2 developing hazards.

Time Limit

Each hazard perception clip is one attempt and cannot be reviewed; Driver CPC part 1a multiple-choice is separate and lasts 1 hour 55 minutes

Passing Score

67 out of 100 on part 1b hazard perception. Part 1a multiple-choice separately requires 85 out of 100 from 100 questions in 1 hour 55 minutes.

Official Format and Scoring

The official part 1b is an interactive video test with 19 clips, 20 scoreable developing hazards, up to 5 points per hazard, and a 67/100 pass mark.

Core skill

Developing vs Potential Hazards

A potential hazard needs monitoring; a developing hazard has started to require a response such as slowing, changing position, or preparing to stop.

Large-vehicle observation

Scanning, Mirrors and Blind Spots

Looking further ahead, checking mirrors before speed or direction changes, managing nearside and front blind spots, and planning for vehicle length.

High-risk conflicts

Vulnerable Road Users

Pedestrians, children, older adults, disabled people, cyclists, motorcyclists, horse riders and mobility scooter users around large vehicles.

Goods-vehicle hazards

Loads, Stability and Restrictions

Long stopping distances, load shift, rollover risk, high-sided crosswinds, low bridges, weight limits, width restrictions and route planning.

Road environment

Junctions, Roundabouts and Motorways

Nearside turns, tail swing, advanced stop lines, roundabout lane discipline, roadworks, motorway red X signals, slip roads and missed exits.

Practice limitation

MCQ Supplement

These questions teach judgement and official concepts, but candidates still need official-style interactive video practice for timing.

UK LGV/HGV Hazard Perception Study Tips from Top Performers

1Practise the moment when a potential hazard becomes a developing hazard, such as a vehicle moving out or a cyclist entering your nearside risk area.

2Use official interactive video practice because timing, motion and click discipline cannot be replicated by MCQs.

3For HGV scenarios, scan further ahead than you would in a car and plan early for length, width, height, weight, braking distance and load stability.

4Build mirror checks before slowing, changing lane, turning, moving off, joining traffic, passing cyclists or responding to motorway signals.

5Pay particular attention to cyclists and pedestrians on the nearside before left turns, at advanced stop lines, in roadworks and at roundabouts.

6Revise Highway Code rules on vulnerable road users, stopping distances, adverse weather, motorway signals, roadworks and long vehicles.

7Revise HGV walkaround checks, load security, height markers and route planning because professional vehicle condition and load decisions affect hazard recognition.
