2024 CCEA GCSE Motor Vehicle and Road User Studies 3070 Practice Paper with Answers

The Highway Code, published for Northern Ireland by the Department for Infrastructure, sets out official guidance for all road users. It combines legal requirements with advisory guidance and is officially described as a book of rules and advice. Answer: rules

[1] mark for 'rules' (or equivalent, e.g. 'regulations'). Reject vague answers such as 'guidance' alone.

The Highway Code system of signs uses shape and colour together to classify a sign's purpose: circular signs generally give orders, triangular signs give warnings, and rectangular signs give information, with colour (e.g. red border, blue background) reinforcing the message. Answer: shapes and colours

[1] mark for 'shapes and colours' (or 'shape and colour'). Do not award for a single unrelated word.

As part of the eyesight check at the start of the practical driving test, the candidate must read a number plate correctly. For a new-style number plate this distance is 20 metres. Answer: 20

[1] mark for '20'. Accept '20.5' only if the candidate specifies an old-style plate; reject any other value.

In the Highway Code sign system, shape indicates the sign's function: circular signs give orders (things drivers must or must not do), such as speed limit or no-entry signs. Answer: order

[1] mark for 'order' (or 'instruction'/'command'). Reject 'warning' or 'information'.

Triangular signs with a red border alert drivers to a hazard ahead, such as a bend or a school crossing, and are therefore classified as warning signs. Answer: warning

[1] mark for 'warning'. Reject 'order' or 'information'.

Distractions that originate from inside the vehicle, such as a ringing phone, a passenger, or the in-car entertainment/navigation system, are classed as internal distractions, as opposed to external distractions from outside the vehicle. Answer: internal

[1] mark for 'internal'. Reject 'external'.

Collision-risk statistics are analysed by several linked factors, including the time of day, the type of road (e.g. rural, urban, motorway) and the type of vehicle involved, as heavier or faster vehicles carry different risks. Answer: vehicle

[1] mark for 'vehicle'.

External distractions arise from outside the vehicle. Any one credible example is acceptable, for example a large roadside advertising billboard drawing the driver's attention away from the road ahead. Answer: an advertising billboard

[1] mark for any valid external distraction, e.g. an advertising hoarding/billboard, a roadside incident, bright lights from oncoming vehicles, pedestrians or animals at the roadside. Reject internal examples (e.g. mobile phone, passengers).

Primary safety features (e.g. good brakes, ABS, tyre grip) help a vehicle avoid a collision in the first place. Secondary safety features, such as airbags and seat belts, instead reduce the severity of injury once a collision has already occurred. Answer: secondary

[1] mark for 'secondary'. Reject 'primary'.

In fog, dipped headlights are used first; if visibility drops further, the driver should also switch on front and rear fog lamps to improve their own visibility to other road users, remembering to switch them off again once visibility improves. Answer: front and rear

[1] mark for 'front and rear'. Reject 'main beam'.

Black ice forms a thin, transparent layer on the road surface that is very difficult to see because it takes on the colour of the road beneath it, making it especially hazardous. Answer: black

[1] mark for 'black'.

BAC stands for Blood Alcohol Concentration, the legal measure of the amount of alcohol present in a driver's bloodstream, used to determine whether a driver is over the legal limit. Answer: alcohol

[1] mark for 'alcohol'.

Emotional states that can impair a driver's judgement and increase collision risk include frustration, aggression and general emotional disturbance; any one of these (other than anger, which is excluded by the question) is acceptable. Answer: frustration

[1] mark for any one of: frustration, aggression, emotional disturbance/distress. Reject 'anger' as it is excluded by the question.

The ageing process affects the senses and the speed at which information is processed and acted upon, so an older driver's reaction times generally become slower. Answer: slower

[1] mark for 'slower'. Reject 'faster' or 'unaffected'.

Peripheral vision is the part of a person's sight that operates outside the direct line of central focus, allowing a driver to detect hazards to the side without turning their head; this is distinct from tunnel vision, where peripheral awareness is reduced. Answer: peripheral

[1] mark for 'peripheral'. Reject 'tunnel'.

Under Northern Ireland's graduated licensing arrangements, a newly qualified driver must display R (restricted) plates for the first year after passing the driving test, and is also restricted to a maximum speed of 45 mph during that period. Answer: R (restricted)

[1] mark for 'R' or 'restricted' (or both). Reject 'L' (learner) plates, which apply to provisional licence holders before passing the test.

The Vehicle Registration Certificate is commonly referred to by its form reference, the V5C, and records details such as the registered keeper, make, model and registration number of the vehicle. Answer: V5C

[1] mark for 'V5C'. Accept 'log book' as an informal equivalent.

The Locomotive Act 1865 (the 'Red Flag Act') required at least one person to walk at least 60 yards ahead of a powered locomotive carrying a red flag to warn other road users, an early example of road traffic legislation. Answer: red

[1] mark for 'red'.

From 1 October 2014, the requirement to display a paper tax disc (vehicle excise licence) in the windscreen was abolished, as vehicle tax records moved to an electronic database. Answer: tax disc

[1] mark for 'tax disc' (or 'vehicle excise licence/duty disc'). Reject 'MOT disc', which is a separate requirement that ended on 6 April 2015.

A cover note is issued by an insurer as temporary evidence of cover, valid for a short period, while the full insurance certificate and policy documents are being prepared. Answer: cover note

[1] mark for 'cover note'. Reject 'certificate of insurance' or 'policy', which are the final documents rather than temporary proof.

Internal distractions originate from inside the vehicle. Two valid examples are: (1) a passenger talking to or distracting the driver, and (2) the driver using a mobile phone or interacting with an in-car entertainment/navigation system. Answer: passengers behaving disruptively; use of a mobile phone or in-car entertainment/navigation system

[1] mark for each of two valid internal distractions (maximum 2), e.g. passengers, mobile phone use, in-car entertainment/navigation systems, eating or drinking, adjusting controls. Reject external distractions.

Junctions are high-risk locations because several traffic movements interact at the same point. Three valid risk factors are: (1) restricted visibility caused by parked vehicles, hedges or buildings; (2) a driver misjudging the speed or distance of an approaching vehicle; and (3) a driver failing to give way or stop as required by signs or markings. Answer: restricted visibility; misjudging speed/distance of other traffic; failing to give way/stop as required

[1] mark for each of three valid factors (maximum 3), e.g. restricted visibility/sightlines, misjudging speed or distance, failing to give way, poor road markings or signing, driver distraction, excessive speed on approach.

Heavy rain affects both the vehicle's grip on the road and the driver's ability to see clearly. Two valid effects are: (1) a wet road surface reduces tyre grip, increasing stopping distances; and (2) windows can become misted or spray from other vehicles can reduce visibility. Answer: reduced tyre grip/longer stopping distances; misted windows or spray reducing visibility

[1] mark for each of two valid effects (maximum 2), e.g. reduced tyre grip, longer stopping distances, misted windows, reduced visibility from spray, risk of aquaplaning.

Fog reduces both visibility and the ability of other road users to see a motorcyclist. Three valid precautions are: (1) reducing speed to match the distance the rider can see to be clear; (2) increasing the following distance from the vehicle in front; and (3) using dipped headlights, and front/rear fog lamps if fitted and visibility is seriously reduced, to improve conspicuity. Answer: reduce speed; increase following distance; use dipped headlights/fog lamps and remain highly conspicuous

[1] mark for each of three valid precautions (maximum 3), e.g. reduce speed, increase following distance, use dipped headlights, use fog lamps if visibility is seriously reduced, wear high-visibility/reflective clothing, keep the visor clear, be prepared to stop.

(i) A circular sign gives an order; a red border with a black number on white is the standard design for a maximum speed limit sign, so this sign orders drivers not to exceed 30 mph. (ii) A triangular sign with a red border is a warning sign; the pedestrian-with-stick symbol warns that blind or deaf pedestrians may be crossing ahead. (iii) A rectangular sign gives information; a blue background with a white 'P' indicates that parking is permitted. (iv) The great majority of Highway Code warning signs are triangular, with a red border, to alert drivers to a hazard ahead. Answer: (i) Order, 30 mph maximum speed limit; (ii) Warning, blind/deaf pedestrians may be crossing; (iii) Information, parking permitted; (iv) Triangular

(i) [1] for 'order', [1] for correct meaning (30 mph maximum speed limit); (ii) [1] for 'warning', [1] for correct meaning (blind/deaf pedestrians crossing); (iii) [1] for 'information', [1] for correct meaning (parking/car park); (iv) [1] for 'triangular'. Total [7].

(a) Reflective road studs use a standard colour code: white studs mark the lane divisions; red studs mark the left-hand/nearside edge of the carriageway; amber/yellow studs mark the right-hand edge or the central reservation of a dual carriageway or motorway; and green studs mark the point where a slip road joins or leaves the main carriageway. (b) Road markings and studs guide and warn drivers about lane position, hazards and permitted movements, which is especially valuable in poor visibility or darkness. (c) Because the studs are retroreflective, they bounce a vehicle's own headlight beam back to the driver, making them highly visible even where there is no street lighting. Since each position on the carriageway uses a different colour, a driver can immediately judge their exact lane position purely from the colour of the studs reflecting back, without needing to see the road surface itself. Answer: (a) white, red, amber/yellow, green; (b) to guide and warn drivers, particularly in poor visibility; (c) they reflect headlights so are visible in the dark, and their colour-coding shows the driver's exact position on the carriageway

(a) [1] each for white, red, amber/yellow, green in the correct positions (max 4); accept 'yellow' for amber. (b) [1] for a valid general purpose. (c) [1] mark for reflectivity/visibility in the dark without street lighting; [1] mark for colour-coding allowing the driver to judge position on the carriageway. Total [7].

(a) The standard traffic light sequence is: red (stop) then red and amber shown together (prepare to move, but must still stop) then green (proceed if safe) then amber alone (stop unless already so close that stopping would be dangerous) then back to red. (b) The primary signal is the main traffic light positioned at or near the stop line, which the approaching driver is required to obey. A secondary signal is an additional, repeater signal placed further into or on the far side of the junction; it shows the same indication and helps a driver confirm the signal is still showing, particularly useful if the primary signal is obscured or once the driver is already committed to the junction. (c) Other than a police officer, people authorised to direct traffic include a traffic warden and a school crossing patrol officer (a 'lollipop' person), as well as authorised persons controlling traffic at roadworks. Answer: (a) Red, Red+Amber, Green, Amber, Red; (b) primary = signal at the stop line the driver must obey; secondary = repeater/confirming signal further into the junction; (c) traffic warden; school crossing patrol officer

(a) [1] for red and amber shown together as the second stage; [1] for green; [1] for amber before the final red — award full [3] only if the complete four-stage cycle is correctly ordered. (b) [1] for a correct description of the primary signal; [1] for a correct description of the secondary signal. (c) [1] mark each for any two valid authorised persons (max 2). Total [7].

(a) Laws and rules exist to protect the safety of all road users by setting shared, minimum standards of behaviour, and to make road use predictable, so that drivers, riders and pedestrians can anticipate what others around them are likely to do. (b) Several organisations, besides central government, work to reduce collisions: for example, the Police Service of Northern Ireland enforces the law through speed and drink-drive checks; local councils install engineering measures such as traffic calming and improved signage; and vehicle manufacturers design and fit safety features such as anti-lock braking systems (ABS) and airbags. Any two such organisations, each with one valid action, are acceptable. (c) The Cycling Proficiency Scheme teaches children the practical riding skills and Highway Code knowledge they need to cycle safely and confidently on the road. Answer: (a) protects road user safety; makes road use predictable; (b) e.g. PSNI — enforces traffic law; vehicle manufacturers — fit safety features; (c) teaches children safe, practical cycling skills and road knowledge

(a) [1] mark each for any two valid reasons (max 2). (b) [1] mark for each of two valid organisations correctly named (max 2) plus [1] mark for each correctly linked action (max 2) — total [4]. (c) [1] mark for a valid statement of purpose. Total [7].

(a) Low winter sun creates strong glare that can temporarily dazzle the driver and make it hard to see the road ahead, while the long shadows it casts can hide hazards such as a pothole, a pedestrian, an animal, or even a patch of black ice in shaded areas. (b) The driver should use the sun visor and, if appropriate, sunglasses to reduce glare; keep the windscreen clean, since dirt and smears make glare worse; and reduce speed, being prepared to stop, since visibility of the road ahead is significantly reduced. (c) Glare and deep shadow reduce the driver's ability to see the road surface clearly and to judge the speed and actions of the vehicle in front. If that vehicle brakes suddenly because of a hazard the following driver cannot yet see, extra following distance provides the additional time and space needed to react and stop safely. Answer: (a) glare from low sun; shadows hiding hazards; (b) use sun visor/sunglasses, keep windscreen clean, slow down; (c) reduced visibility means more time/distance is needed to react safely to the vehicle ahead

(a) [1] mark each for any two valid hazards (max 2). (b) [1] mark each for any two valid actions (max 2). (c) [1] mark for identifying reduced visibility/ability to judge the vehicle ahead; [1] mark for linking this to the need for extra time/distance to react safely. Total [6].

(a) In Northern Ireland, a person may apply for a provisional driving licence for a car from the age of 17. (b) During the first year after passing the driving test, a newly qualified driver must display R (restricted) plates and must not exceed 45 mph, even where the general speed limit is higher. (c) Documents (other than the driving licence) that relate to driving and owning a vehicle include, for example, the insurance certificate, the Vehicle Registration Certificate/V5C, and the Vehicle Test Certificate (MOT); any three valid examples are acceptable. (d) SORN stands for Statutory Off Road Notification. (e) A SORN is a declaration made to the licensing authority that a vehicle is being kept off the public road; once made, the vehicle does not need to be taxed or insured for road use until it returns to the road. Answer: (a) 17; (b) 45 mph; (c) e.g. insurance certificate, V5C, MOT certificate; (d) Statutory Off Road Notification; (e) declares the vehicle is off the road so it need not be taxed/insured

(a) [1] for '17'. (b) [1] for '45 mph'. (c) [1] mark each for any three valid documents (max 3), e.g. insurance certificate/cover note, V5C, MOT/Vehicle Test Certificate, VED evidence. (d) [1] for 'Statutory Off Road Notification'. (e) [1] for a correct explanation. Total [7].

(a) The three main types of motor insurance cover are: third party (covers damage/injury to others only); third party, fire and theft (adds cover for the policyholder's own vehicle if it is stolen or damaged by fire); and comprehensive (also covers damage to the policyholder's own vehicle from other causes). (b) The excess is the first part of any claim that the policyholder must pay themselves; the insurer only pays the remaining balance above this amount. (c) Insurance companies also consider factors such as the make, model, performance or engine capacity of the vehicle, the age or value of the vehicle, the area where the driver lives, the driver's record and any no-claims discount, the vehicle's security features, and the type of use. Any two valid factors are acceptable. Answer: (a) third party; third party, fire and theft; comprehensive; (b) the amount the policyholder pays first towards a claim, before the insurer pays the rest; (c) e.g. vehicle make/model/engine capacity, area of residence, driving record, vehicle security, type of use

(a) [1] mark each for the three correctly named types of cover (max 3). (b) [1] mark for identifying it as an amount paid by the policyholder; [1] mark for correctly explaining it is paid first/before the insurer pays the remainder. (c) [1] mark each for any two valid factors (max 2). Total [7].

(a) Petrol engine exhaust emissions contain several toxic or harmful gases, including carbon monoxide, oxides of nitrogen, sulphur dioxide and hydrocarbons; any two are acceptable. (b) Vehicle pollution has been reduced through technology such as catalytic converters, the switch to unleaded fuel, stop/start systems that cut the engine at rest, and the development of hybrid and electric vehicles. (c) From 1 October 2014, drivers were no longer required to display a paper vehicle tax disc, as records moved to an electronic database. (d) The requirement to display an MOT disc on the windscreen in Northern Ireland ended on 6 April 2015. (e) Noise from busy roads is a concern for nearby residents because it causes annoyance and stress and can disturb sleep and concentration; prolonged, very high exposure can also contribute to hearing damage. Answer: (a) e.g. carbon monoxide, oxides of nitrogen; (b) e.g. catalytic converters, unleaded fuel, stop/start technology, hybrid/electric vehicles; (c) 1 October 2014; (d) 6 April 2015; (e) causes annoyance/stress and disturbs sleep

(a) [1] mark each for any two valid toxic gases (max 2): carbon monoxide, oxides of nitrogen, sulphur dioxide, hydrocarbons, lead, carbon dioxide. (b) [1] mark each for any two valid technologies (max 2). (c) [1] for '1 October 2014'. (d) [1] for '6 April 2015'. (e) [1] for a valid reason. Total [7].

(a) The recommended sequence after a collision is, first, to protect the scene (e.g. using hazard warning lights and a warning triangle to warn approaching traffic); second, to summon the emergency services, giving accurate details of the location and casualties; and third, to ensure that the vehicles involved are made safe (e.g. switching off engines, applying handbrakes). (b) BBC stands for Breathing, Bleeding and Consciousness — the order in which a casualty's condition should be checked and treated, dealing with the most immediately life-threatening problem first. Answer: (a) protect the scene, summon emergency services, ensure vehicles are safe; (b) Breathing, Bleeding, Consciousness

(a) [1] mark each for the three actions named in the correct order (max 3): protect the scene, summon emergency services, ensure vehicles are made safe; award [2] only if all three are correct but not in order. (b) [1] mark each for Breathing, Bleeding, Consciousness (max 3). Total [6].

(a) Fuel consumption (km/L) = distance ÷ volume of fuel = \( 425 \div 50 = 8.5 \text{ km/L} \). (b) Convert the distance and the fuel volume into miles and gallons, then divide: distance in miles = \( 425 \div 1.609 = 264.1 \text{ miles} \); fuel used in gallons = \( 50 \div 4.546 = 11.0 \text{ gallons} \); fuel consumption = \( 264.1 \div 11.0 = 24.0 \text{ mpg} \), which rounds to 24 mpg. Checking by a second method: \( 8.5 \times 1.609 \times 4.546 = 24.0 \text{ mpg} \), confirming the same result. (c) Real-world mpg can differ from the manufacturer's quoted figure for reasons such as: driving style (harsh acceleration/braking uses more fuel than smooth driving); traffic conditions (stop-start urban traffic increases consumption compared with steady motorway cruising); the load carried in the vehicle; incorrect tyre pressure; and short journeys, where the engine may not reach its most efficient operating temperature. Any two valid reasons are acceptable. Answer: (a) 8.5 km/L; (b) 24 mpg; (c) e.g. driving style, traffic conditions, vehicle load, tyre pressure, short journeys

(a) [1] mark for the correct method (distance ÷ fuel volume); [1] mark for the correct answer, 8.5 km/L (units required for full marks). (b) [1] mark for converting distance to miles or fuel to gallons correctly; [1] mark for the second conversion; [1] mark for the correct final answer of approximately 24 mpg (accept 23–25 mpg, ECF/OFR applies from part (a)). (c) [1] mark each for any two valid reasons (max 2). Total [7].

(a) Total distance = Millbrook to Oakford + Oakford to Riverstown + Riverstown to Thornhill = \( 18 + 15 + 19 = 52 \text{ miles} \). (b) Time = distance ÷ speed = \( 52 \div 40 = 1.3 \text{ hours} \). Converting the decimal part to minutes: \( 0.3 \times 60 = 18 \) minutes, so the journey takes 1 hour 18 minutes. Checking by a second method: at 40 mph the car covers \( \frac{40}{60} = 0.667 \) miles per minute, so 52 miles takes \( 52 \div 0.667 = 78.0 \) minutes = 1 hour 18 minutes, confirming the answer. (c) Arrival time = \( 09{:}15 + 1{:}18 = 10{:}33 \). (d) Time for the direct route = \( 47 \div 50 = 0.94 \text{ hours} = 0.94 \times 60 = 56.4 \text{ minutes} \), i.e. approximately 56 minutes. The indirect route took 78 minutes, so the direct route is faster by \( 78 - 56.4 = 21.6 \), approximately 22 minutes earlier. Answer: (a) 52 miles; (b) 1 hour 18 minutes; (c) 10:33; (d) approximately 22 minutes earlier

(a) [1] mark for correctly identifying and adding the three relevant chart values; [1] mark for the correct total, 52 miles. (b) [1] mark for the correct method (distance ÷ speed); [1] mark for 1.3 hours (or equivalent); [1] mark for the correct final answer, 1 hour 18 minutes; apply ECF/OFR from part (a). (c) [1] mark for the correct arrival time, 10:33, following on from part (b) (ECF/OFR applies). (d) [1] mark for correctly calculating the direct journey time (approximately 56 minutes); [1] mark for the correct time difference, approximately 22 minutes earlier (accept 21–22 minutes). Total [8].

(i) The oil pump draws oil from the sump and forces it under pressure around the engine to lubricate moving parts. (ii) The strainer is a fine mesh screen at the pump's oil pick-up point that stops large debris entering the pump. (iii) The oil filter removes fine dirt and carbon particles from the circulating oil, protecting bearing surfaces from wear. (iv) The sump is the reservoir at the base of the engine that stores the oil supply. (v) The dipstick is a graduated rod that a motorist withdraws to check the oil level in the sump. (vi) As oil circulates, it passes over and through hot moving components such as the bearings, pistons and cylinder walls, absorbing frictional and combustion heat by direct contact; the oil then carries this heat back to the sump, where it is dissipated, so as well as reducing friction and wear, the lubrication system helps to remove heat from the engine's internal components. Answer: (i) oil pump; (ii) strainer; (iii) oil filter; (iv) sump; (v) dipstick; (vi) oil absorbs heat from hot moving parts by circulating over them and carries it away to the sump, contributing to cooling

(i)-(v) [1] mark each for the correctly named component (max 5): oil pump, strainer, oil filter, sump, dipstick. (vi) [1] mark for identifying that oil absorbs/carries away heat from hot moving parts; [1] mark for explaining that this heat is released/dissipated as the oil returns to/passes through the sump. Total [7].

(i) The fuel tank stores the vehicle's fuel supply. (ii) The fuel pump draws fuel from the tank and delivers it, under pressure, to the engine. (iii) The fuel filter removes impurities and debris from the fuel before it reaches the engine, protecting the injectors from blockage. (iv) The air filter removes dust and airborne particles from the air drawn into the engine, protecting internal components from abrasive wear. (v) The fuel injector (part of the fuel injection system) delivers a precisely metered, atomised spray of fuel into the inlet manifold or directly into the cylinders. (vi) Basic maintenance checks/safety precautions for the fuel system include: regularly checking and, where necessary, replacing the air filter; checking fuel lines and connections for leaks; and avoiding naked lights or flames near the fuel system because petrol vapour is highly flammable. Any two of these are acceptable. Answer: (i) fuel tank; (ii) fuel pump; (iii) fuel filter; (iv) air filter; (v) fuel injector/injection system; (vi) e.g. check for fuel leaks; check/replace air filter; avoid naked lights near fuel

(i)-(v) [1] mark each for the correctly named component (max 5): fuel tank, fuel pump, fuel filter, air filter, fuel injector/fuel injection system. (vi) [1] mark each for any two valid checks/precautions (max 2). Total [7].

(i) The radiator transfers heat from the hot coolant passing through its tubes and fins to the surrounding air. (ii) The thermostat is a temperature-sensitive valve that restricts coolant flow to the radiator until the engine reaches its normal operating temperature, then opens to regulate temperature. (iii) The water pump, usually belt-driven, circulates coolant continuously around the engine and radiator. (iv) The radiator cap seals the system, maintains it under pressure and allows coolant to be topped up; it also incorporates a pressure-relief valve. (v) The expansion (or header) tank accommodates coolant as it expands with heat and provides a reserve supply to the system. (vi) Basic maintenance checks for the cooling system include: checking the coolant level is between the minimum and maximum marks; checking the strength/concentration of the antifreeze, especially before winter; and checking the condition of the hoses and the water pump drive belt for wear, cracking or leaks. Any two of these are acceptable. Answer: (i) radiator; (ii) thermostat; (iii) water pump; (iv) radiator cap; (v) expansion/header tank; (vi) e.g. check coolant level; check antifreeze strength; check hoses/drive belt condition

(i)-(v) [1] mark each for the correctly named component (max 5): radiator, thermostat, water pump, radiator cap, expansion/header tank. (vi) [1] mark each for any two valid checks (max 2). Total [7].

(i) The brake master cylinder converts the mechanical force applied by the driver's foot on the brake pedal into hydraulic pressure, which is then transmitted through the brake fluid. (ii) The servo uses the difference between atmospheric pressure and engine (inlet manifold) vacuum to boost the force applied by the driver, reducing the physical effort needed to brake firmly. (iii) The brake pipes carry brake fluid under pressure from the master cylinder to the slave/wheel cylinders or calipers at each wheel. (iv) The disc pad is a friction pad that is pressed by the caliper against the rotating brake disc to slow the wheel. (v) The handbrake is a mechanically (cable) operated brake, independent of the hydraulic footbrake system, used mainly to hold a stationary vehicle. (vi) Disc brakes are more open to the air than the enclosed drum design, so they dissipate the heat generated by friction more effectively; this makes them less prone to brake fade (a temporary loss of braking efficiency caused by overheating) during heavy or repeated braking, such as on a long descent. Answer: (i) brake master cylinder; (ii) servo; (iii) brake pipes; (iv) disc pad; (v) handbrake; (vi) discs dissipate heat better than drums (being more exposed to air), so are less prone to brake fade

(i)-(v) [1] mark each for the correctly named component (max 5): brake master cylinder, servo, brake pipes, disc pad, handbrake. (vi) [1] mark for a valid advantage (e.g. better heat dissipation, less prone to fade, perform better when wet); [1] mark for a correct supporting reason linked to the advantage stated. Total [7].

Driver behaviour is a major contributory factor in road traffic collisions. Causes include internal and external distractions (such as mobile phone use or roadside advertising), fatigue (particularly on long or monotonous journeys), driving under the influence of alcohol or drugs, inexperience in new drivers, and excessive or inappropriate speed for the conditions. These risks can be reduced through improved driver education and training, sustained road safety publicity and awareness campaigns, stricter enforcement of traffic law (e.g. roadside breath testing, penalty points for phone use), and technology that discourages risky behaviour (e.g. mobile phone detection cameras, speed cameras). A strong answer links specific causes to specific, realistic prevention measures rather than listing them separately. Answer: causes include distraction, fatigue, alcohol/drugs, inexperience and speeding; these can be reduced through driver education, publicity campaigns, stricter enforcement and relevant technology

Level 1 (1–2 marks): basic, unlinked statements identifying one or two causes and/or prevention measures, with limited use of specialist vocabulary. Level 2 (3–4 marks): a reasonably organised response identifying several valid causes and prevention measures, with some attempt to link cause to solution. Level 3 (5–6 marks): a well-organised, detailed response that clearly links specific causes of collisions to specific, realistic prevention measures, using appropriate specialist vocabulary throughout. Quality of written communication is assessed in this question. Total [6].

Vehicle engineering: Primary safety features help a vehicle avoid a collision in the first place — for example, an anti-lock braking system (ABS) allows a driver to brake hard while retaining steering control, well-maintained brakes and tyres ensure the vehicle can stop safely, and effective lighting improves the driver's ability to see and be seen. Secondary safety features reduce the severity of injury once a collision has already occurred, such as airbags, seat belts and crumple zones, which absorb impact energy. Regular maintenance and the compulsory MOT test also help ensure that safety-critical systems remain in good working order throughout the vehicle's life. Driver behaviour: Good observation and anticipation allow a driver to identify developing hazards early and respond in good time. Obeying speed limits and the guidance in the Highway Code reduces the likelihood and severity of collisions, since lower speeds allow more time to react and shorten stopping distances. Avoiding distraction, fatigue and driving under the influence of alcohol or drugs keeps a driver's attention and judgement at the level needed for safe driving. Undertaking further training beyond the basic test can also improve hazard awareness and control skills over time. A well-balanced answer gives roughly equal, detailed treatment to both headings, using specialist vocabulary such as ABS, primary/secondary safety, stopping distance and hazard perception. Answer: vehicle engineering (primary/secondary safety features, maintenance/MOT) and driver behaviour (observation, obeying rules, avoiding distraction/fatigue/alcohol, further training) both contribute to preventing collisions, as detailed above

Level of Response mark scheme (Quality of Written Communication assessed): Level 1 (1–3 marks): basic, list-like points with little structure, addressing one or both headings only superficially, with limited specialist vocabulary and weaker spelling/punctuation/grammar. Level 2 (4–7 marks): a reasonably organised response that addresses both headings with relevant, mostly accurate examples, but with limited depth or an imbalance between the two headings; some appropriate specialist vocabulary used. Level 3 (8–10 marks): a well-organised, balanced response that covers both headings in depth with accurate, specific examples, uses specialist vocabulary confidently, and is written with clear, accurate spelling, punctuation and grammar. Total [10].

Vehicle engineering: Collisions can be caused by mechanical failure resulting from poor maintenance, such as worn or under-inflated tyres reducing grip, or defective brakes increasing stopping distance. To address this, manufacturers have developed technology such as ABS to help drivers retain control under heavy braking, and government requires the compulsory MOT test to check that safety-critical systems remain roadworthy throughout the vehicle's life; manufacturers also design vehicles with better handling, visibility and crash structures to reduce the chance and severity of collisions. Driver behaviour: Many collisions are caused by driver behaviour, such as excessive speed, distraction, fatigue on long journeys, and driving under the influence of alcohol or drugs. Government reduces this risk through legislation (such as drink-drive limits and the penalty points system), roadside enforcement (breath testing, speed cameras, mobile phone detection cameras), and sustained road safety publicity campaigns run through bodies such as the Department for Infrastructure. A well-balanced answer links specific causes under each heading to a specific method used to reduce them, using accurate specialist vocabulary. Answer: vehicle engineering causes (mechanical failure, worn tyres/brakes) are addressed through MOT testing and technology such as ABS; driver behaviour causes (speeding, distraction, fatigue, alcohol) are addressed through legislation, enforcement and publicity campaigns, as detailed above

Level of Response mark scheme (Quality of Written Communication assessed): Level 1 (1–3 marks): basic, list-like points with little structure, addressing one or both headings only superficially, with limited specialist vocabulary and weaker spelling/punctuation/grammar. Level 2 (4–7 marks): a reasonably organised response that addresses both headings with relevant, mostly accurate examples of causes and reduction methods, but with limited depth or an imbalance between the two headings; some appropriate specialist vocabulary used. Level 3 (8–10 marks): a well-organised, balanced response that covers both headings in depth with accurate, specific examples of causes and corresponding reduction methods, uses specialist vocabulary confidently, and is written with clear, accurate spelling, punctuation and grammar.
