Question 1061Question →

Before negotiating a sharp bend on a rural road, a driver fully depresses the clutch pedal and freewheels into the corner. Why is this action hazardous to vehicle control?

Show answer & explanation

Answer: It removes engine braking and degrades steering stability through the turn.

Answer

It removes engine braking and degrades steering stability through the turn.
Under Highway Code Rule 122, coasting (travelling in neutral or with the clutch pressed down) removes engine braking, causing the vehicle to rely entirely on the footbrake and significantly reducing steering response and stability on corners.

Step-by-Step Solution

1
Analyze the mechanical consequence of keeping the clutch pedal pressed down when approaching a bend.
Disengaging the clutch separates the engine from the driven wheels, eliminating the natural restraining effect of engine braking.
Engine braking provides predictable deceleration without relying solely on the footbrake.
2
Evaluate the vehicle handling consequences of coasting into a turn under Highway Code Rule 122.
Without engine power driving the wheels or engine braking steadying the chassis, the car has less directional stability and steering response becomes less precise.
Maintaining gear engagement keeps the vehicle settled and responsive throughout the corner.

Key Concept

Coasting reduces vehicle control by eliminating engine braking and impairing steering responsiveness, particularly on bends.

While driving along an urban street with integrated tram tracks, you notice a diamond-shaped traffic sign displaying a number. What does this sign mean for you as a car driver?

Show answer & explanation

Answer: It provides instructions and speed limits that apply exclusively to tram drivers.

Answer

The sign gives instructions and speed regulations that apply exclusively to tram drivers.
Under UK Highway Code Rule 301, diamond-shaped signs are unique to tram networks and give instructions, speed limits, and directions exclusively to tram drivers. Other road users should be aware of them but must obey standard traffic signs.

Step-by-Step Solution

1
Identify the shape and category of the road sign.
The sign is diamond-shaped with numerical information.
Road sign shapes define their category and regulatory target audience in the UK.
2
Apply UK Highway Code rules regarding tramway signage (Rule 301).
Diamond-shaped signs are specifically designed for and apply only to tram operators.
General motorists are governed by standard circular, triangular, and rectangular signs.
3
Determine driver responsibility.
Recognise the sign as relevant only to trams and continue following standard traffic signage.
Car drivers must not confuse tram-specific instructions with general traffic regulations.

Question 1063Question →

You are navigating a busy multi-lane one-way system in a city centre when an incoming telephone call rings through your vehicle's hands-free system. What is the safest course of action?

Show answer & explanation

Answer: Ignore the incoming call and wait until you have safely parked before retrieving any messages

Answer

Ignore the incoming call and wait until you have safely parked before retrieving any messages.
Even though hands-free systems are legally permitted if used without holding the handset, conducting a phone call creates substantial cognitive distraction. In demanding traffic conditions, such as a multi-lane urban road, the safest action is to ignore the call and allow it to go to voicemail until you are parked safely.

Step-by-Step Solution

1
Assess the current driving environment and workload
Recognise that navigating a multi-lane city centre requires high concentration, rapid hazard perception, and continuous scanning.
Complex road layouts with multiple lanes and pedestrians present an elevated risk of collisions.
2
Evaluate the risk of engaging with hands-free technology
Determine that answering or checking the call introduces cognitive and visual distractions that impair reaction times.
Hands-free phone conversations still divert significant mental focus away from the road.
3
Select the safest driving decision
Allow the call to ring out to voicemail and postpone all communication until parked in a safe and legal place.
Prioritising driving safety over communication eliminates distraction entirely.

Question 1064Question →

How do specific driver actions relate to UK environmental standards and noise control regulations? Match each vehicle operation with its direct regulatory or environmental outcome.

Click a left item, then click its matching right item

Items

Leaving the engine running while de-icing windscreen glass on a residential driveway
Fitting an aftermarket exhaust pipe modified to increase exhaust sound volume
Sounding the horn on a lit 30 mph urban road at 01:00 to get a friend's attention
Driving away smoothly as soon as the engine has started from cold

Matches

Show answer & explanation

Answer

Leaving the engine running while de-icing matches producing unnecessary emissions and stationary noise; fitting an aftermarket exhaust modified to increase noise matches breaching vehicle construction regulations on statutory noise thresholds; sounding the horn on an urban road at 01:00 matches violating the legal nighttime curfew on horn use; and driving away smoothly from cold matches enabling the engine and catalytic converter to reach optimal operating temperature quickly.
Each pair directly aligns with UK driving regulations and environmental guidance: stationary engine idling causes avoidable pollution, modified noisy exhausts breach vehicle construction limits, casual horn use between 23:30 and 07:00 in urban areas violates statutory curfew rules, and driving smoothly from cold reduces emission warm-up times.

Step-by-Step Solution

1
Evaluate stationary engine idling rules and environmental impact.
Leaving an engine running while parked or de-icing creates unnecessary exhaust gases and noise pollution without warming the engine effectively.
The Highway Code advises against leaving stationary engines idling.
2
Review UK vehicle construction rules regarding exhaust sound modifications.
Exhaust systems cannot legally be altered to exceed statutory noise limits.
Regulations strictly prohibit modifying silencers to make them louder than standard type-approved systems.
3
Apply the statutory nighttime horn restrictions.
Using the horn non-emergently between 23:30 and 07:00 in a built-up area is illegal.
The Highway Code restricts horn use at night on roads with street lighting.
4
Assess modern eco-driving practice for cold engine warm-up.
Driving off immediately at moderate engine speeds brings catalytic converters and particulate filters up to working temperature rapidly.
Catalytic converters require rapid heating under gentle load to effectively clean exhaust gases.

Question 1065Question →

A driver may lawfully hold and operate a mobile phone to adjust navigation while stopped in a queue at traffic lights, provided the vehicle's automatic start-stop system has switched off the engine.

Show answer & explanation

Answer: False

Answer

False. Drivers must not hold or operate a handheld mobile device while stationary at traffic lights, even if the engine has stopped automatically.
Under UK law and Highway Code Rule 149, it is an offence to hold and use a phone or handheld device while driving. This prohibition applies continuously while on the road, including when stopped at traffic lights or queuing in traffic. Start-stop systems cutting the engine do not constitute being safely parked.

Step-by-Step Solution

1
Determine the legal definition of driving in relation to queues and traffic signals.
Being stopped at red lights or in traffic congestion is legally classified as active driving.
The driver must remain fully alert, monitor changing road conditions, and be ready to move off safely at any moment.
2
Assess whether automated start-stop technology changes this status.
Automatic engine cut-off does not mean the vehicle is safely parked.
Start-stop is a temporary operational state on an active carriageway, not a safe and lawful parking manoeuvre.
3
Apply the regulations regarding handheld device usage.
The action is illegal and creates dangerous in-car distraction.
Handheld phone use is prohibited unless safely parked or in specific statutory exemptions (such as making a 999 call when unsafe to stop).

Question 1066Question →

You are preparing to transport several heavy, solid items in the luggage compartment of your car. What is the safest way to position and secure this load?

Show answer & explanation

Answer: Position the heaviest items on the boot floor against the rear seat back and secure them firmly with restraint straps

Answer

Position the heaviest items on the boot floor against the rear seat back and secure them firmly with restraint straps
Placing the heaviest items directly on the floor and pushed flush against the rear seat back keeps the vehicle's centre of gravity as low and central as possible. Securing the load with straps prevents dangerous load shifting during cornering or emergency braking, ensuring stable handling and occupant safety.

Step-by-Step Solution

1
Determine the optimal position for heavy cargo inside the vehicle
Heavy cargo must be placed on the floor of the luggage compartment as low as possible and up against the rear seat back structure.
Keeping weight low maintains a low centre of gravity, while placing it directly against the seat back prevents momentum from building if the vehicle stops suddenly.
2
Apply physical restraints to prevent dynamic load shifting
Fasten cargo firmly using dedicated anchor points and heavy-duty straps.
Unsecured items can shift during cornering, causing sudden instability or bursting through seat backs in a collision.

Question 1067Question →

You are driving down a busy high street lined with parked vehicles. Ahead, you notice an older pedestrian waiting to cross the carriageway from between two stationary cars. Why must you exercise extra caution and be prepared to slow down?

Show answer & explanation

Answer: Older pedestrians may need additional time to cross and may have difficulty judging approaching vehicle speeds.

Answer

Older pedestrians may need additional time to cross and may have difficulty judging approaching vehicle speeds.
Older road users may have reduced mobility, impaired eyesight, or reduced hearing. These factors make it more challenging for them to accurately estimate how quickly an approaching vehicle is moving, and they may require significantly more time to cross safely.

Step-by-Step Solution

1
Identify the vulnerable road user and road context
Recognise that an older pedestrian is preparing to cross between parked cars on a busy street.
Early detection of vulnerable road users gives the driver necessary time to adapt speed and position.
2
Assess physiological and cognitive factors affecting the pedestrian
Acknowledge that older people may take more time to cross and might struggle to accurately judge vehicular speed and distance.
Natural sensory and mobility decline can alter crossing pace and gap evaluation in traffic.
3
Determine the appropriate defensive driving response
Reduce speed, stay alert for sudden movements, and give the pedestrian ample time and space.
Highway Code guidance emphasises patience, caution, and consideration around older and disabled road users.

Question 1068Question →

If the Electronic Stability Control (ESC) warning light flashes intermittently while driving on a slippery road, it indicates that the system has suffered a permanent fault and is completely disabled.

Show answer & explanation

Answer: False

Answer

False
The statement is false because a flashing ESC light indicates that the system is actively working to regain stability and traction during hazardous road conditions. A permanent fault is indicated when the warning light remains solidly illuminated.

Step-by-Step Solution

1
Identify the specific behaviour of the Electronic Stability Control (ESC) dashboard light described in the statement.
The light is flashing intermittently during slippery driving conditions rather than remaining steadily lit.
Dashboard instrumentation utilizes flashing versus continuous illumination to distinguish between active interventions and permanent component faults.
2
Differentiate between real-time active system intervention and a system failure mode.
Intermittent flashing signals that the vehicle has detected wheel slip or a skid and is actively applying braking or adjusting engine torque to assist the driver, whereas a solid, steady warning light indicates a malfunction or that the system has been switched off.
Understanding instrument indicators ensures the driver recognizes vehicle stability events and does not misdiagnose active safety operation as a breakdown.

Question 1069Question →

You are driving on a road where tram rails are embedded in the surface. Why must you give extra room when following or overtaking a cyclist?

Show answer & explanation

Answer: The cyclist's tyres may slip on the rails or get caught in the tracks, causing them to wobble or swerve.

Answer

The cyclist's tyres may slip on the rails or get caught in the tracks, causing them to wobble or swerve.
Metal tram rails create a slippery surface, especially in wet weather, and have recessed grooves that can easily catch narrow bicycle tyres. As a result, cyclists may suddenly wobble, lose balance, or swerve to cross the tracks at a safe right angle. Drivers must leave plenty of room to allow for these sudden movements.

Step-by-Step Solution

1
Identify the specific physical road hazard presented by tram tracks to two-wheeled vehicles.
Tram rails consist of smooth metal running surfaces and narrow sunken grooves embedded in the roadway.
Vulnerable road users with narrow tyres, such as cyclists, face unique balance and steering challenges on these surfaces.
2
Determine the likely movement or reaction of a cyclist encountering these rails.
A cyclist may need to steer across the tracks at a direct angle or may unexpectedly slip or swerve if their tyre catches in the rail groove.
Following drivers must provide ample clearance so the cyclist has room to manoeuvre safely without risk of collision.

Question 1070Question →

When driving along a street lined with parked cars, why can it be particularly difficult to spot powered wheelchairs and mobility scooters?

Show answer & explanation

Answer: They sit low to the ground and can be easily obscured by stationary vehicles

Answer

They sit low to the ground and can be easily obscured by stationary vehicles
Powered wheelchairs and mobility scooters sit low to the road surface. Because of their compact size and low height, they can easily be obscured by parked cars, delivery vans, and street furniture. Drivers must reduce their speed, scan carefully between stationary vehicles, and anticipate that a mobility scooter user may emerge from behind a parked vehicle.

Step-by-Step Solution

1
Identify the physical characteristics of powered wheelchairs and mobility scooters.
These vehicles are small, compact, and positioned much lower than conventional motor vehicles.
Understanding vehicle dimensions is essential for anticipating visibility challenges on the road.
2
Evaluate how road surroundings, such as parked cars, interact with low-profile road users.
Stationary vehicles and street furniture can easily block a driver's line of sight, hiding the scooter until it moves into view.
Drivers need to maintain reduced speeds and scan between parked vehicles to spot vulnerable road users early.

Question 1071Question →

You are waiting to turn right from a side road onto a busy carriageway. Which TWO precautions should you take to account for motorcyclists before emerging?

Select all that apply

Show answer & explanation

Answer: Look specifically for approaching motorcycles, as their narrow profile makes them harder to spot; Allow extra margin for error because judging the speed and distance of an oncoming motorcycle is difficult

Answer

Look specifically for approaching motorcycles due to their narrow profile, and allow an extra safety margin because judging their speed and distance is difficult.
Motorcycles present a much smaller visual profile than cars or lorries, making them harder to detect against busy backgrounds and easier to hide behind vehicle bodywork. Furthermore, their compact dimensions create an optical illusion where estimating their speed and arrival time is challenging, requiring drivers to take extra care and time before emerging.

Step-by-Step Solution

1
Identify the unique visibility characteristics of motorcycles at junctions
Motorcycles have a small, narrow frontal profile that easily blends into background traffic or gets masked by vehicle pillars.
Drivers must actively scan for smaller profiles rather than just looking for cars or lorries.
2
Evaluate the perceptual challenges of oncoming two-wheeled vehicles
Due to their size and single headlight setup, approaching motorcycles frequently appear to be further away and travelling slower than their actual speed.
An extra safety gap is necessary before pulling out across the carriageway.

Question 1072Question →

You are loading your car with heavy luggage in the boot and securing additional equipment on a roof rack. Which TWO adjustments should you make to ensure your vehicle remains safe and stable to drive?

Select all that apply

Show answer & explanation

Answer: Increase tyre pressures to the recommended laden setting in the vehicle handbook; Adjust the aim of your headlights downwards to compensate for the rear dip

Answer

Increase tyre pressures to the recommended laden setting and adjust headlight beam aim downwards.
When a vehicle carries heavy luggage in the boot and on a roof rack, the extra weight compresses the rear suspension and increases load on the tyres. Drivers must increase tyre pressures to the specified loaded pressure in the vehicle manual to maintain control and prevent tyre failure, and lower the headlight beam angle using the in-car adjuster to avoid blinding oncoming traffic.

Step-by-Step Solution

1
Assess the effect of heavy weight on tyre dynamics
Identify that additional payload requires higher tyre pressure to prevent sidewall deformation and overheating
Vehicle handbooks specify higher pressure settings for laden conditions to preserve vehicle control and structural tyre integrity.
2
Assess the geometric change in vehicle pitch from boot loading
Recognise that the rear suspension drops, pointing headlight beams upward into oncoming traffic
Headlight levelling controls must be adjusted downwards to maintain road illumination without dazzling other drivers.
3
Evaluate the effects on vehicle braking and speed dynamics
Understand that heavier vehicles require longer distances to stop due to increased momentum
Extra mass increases inertia, demanding greater braking effort and distance.

You are driving in an urban area and intend to turn left into a side road. As you slow down and prepare to make the turn, you notice a cyclist in your nearside mirror travelling straight ahead along the left-hand side of the road. At the same time, another car is waiting to pull out of the side road. What should you do?

Show answer & explanation

Answer: Hold back behind the cyclist and allow them to pass the junction before you initiate the turn

Answer

Hold back behind the cyclist and allow them to pass the junction before you initiate the turn.
Under Highway Code Rule H3 and the Hierarchy of Road Users, drivers must give way to cyclists travelling straight ahead when turning into or out of a junction. You should never cut across their path or overtake them immediately before turning. Holding back until the cyclist has cleared the junction eliminates the collision risk.

Step-by-Step Solution

1
Assess the multi-hazard scenario in mirrors and surroundings
Identify that the cyclist on the nearside is proceeding straight ahead and has priority over turning traffic.
Highway Code Rule H3 establishes that drivers must not cut across cyclists going ahead when turning into a junction.
2
Manage following position and speed
Slow down and remain safely behind the cyclist rather than attempting to overtake or turn across them.
Attempting to overtake and turn across a cyclist introduces severe blind-spot and collision risks.
3
Complete the left turn safely
Wait until the cyclist has safely cleared the junction mouth and then proceed with the turn while monitoring the emerging car.
Ensures full compliance with the hierarchy of road users and prevents side-impact collisions.

You are driving behind an 8 mph Class 3 invalid carriage along a multi-lane urban road. Approaching a busy roundabout where the rider signals right, the vehicle slows down and stays near the left-hand kerb rather than moving into the right-hand lane. What should you anticipate regarding the rider's intentions?

Show answer & explanation

Answer: The rider may stop on the left to wait for a safe gap in traffic or navigate the turn using pedestrian crossing facilities.

Answer

The rider may stop on the left to wait for a safe gap in traffic or navigate the turn using pedestrian crossing facilities.
Under Highway Code Rule 44, riders of powered wheelchairs and mobility scooters turning right at busy junctions or roundabouts may stop on the left to wait for a safe gap in traffic or navigate the turn using pedestrian crossing facilities instead of moving into the right-hand lane.

Step-by-Step Solution

1
Identify the vehicle class and operating characteristics.
The vehicle is a Class 3 invalid carriage (maximum road speed 8 mph), which is considerably slower and more vulnerable than standard motor traffic.
Class 3 mobility vehicles have specific provisions under the Highway Code to protect vulnerable users at complex junctions.
2
Apply Highway Code rules for right-turning invalid carriages and mobility scooters.
According to Highway Code Rule 44, when turning right in dense or fast traffic, mobility scooter riders may find it safer to stop on the left and wait for a safe gap, or temporarily move onto the pavement/pedestrian crossing facilities.
Moving into the center or right-hand lane of a multi-lane roundabout can expose slow-moving mobility vehicles to significant danger.
3
Determine the appropriate driver response.
Anticipate that the rider is executing a planned safety manoeuvre, give them plenty of room, and do not assume they are turning immediately into your path or merely parking.
Recognising this specific Highway Code procedure prevents collisions and avoids pressurising the vulnerable road user.

You are travelling along a narrow road approaching a sharp, blind bend when a fire engine displaying flashing blue lights and sounding its siren approaches from behind. What should you do to allow it to pass safely?

Show answer & explanation

Answer: Continue driving at a safe speed past the bend and pull over where there is a safe, clear space to let it through

Answer

Continue driving at a safe speed past the bend and pull over where there is a safe, clear space to let it through
Under Highway Code Rule 219, when an emergency vehicle approaches with flashing lights and sirens, you should look for a safe place to pull over. You must not stop where it would compromise safety, such as on the brow of a hill, before a bend, or in a narrow stretch of road. Continuing smoothly past the hazard until a safe pulling-in area is found allows the emergency vehicle to pass without danger.

Step-by-Step Solution

1
Assess the immediate road environment and identify the hazard of stopping on or before a blind bend
Recognised that stopping before a blind bend severely restricts visibility for oncoming traffic and the emergency vehicle
Highway Code Rule 219 advises against stopping where doing so would create a danger to other road users
2
Maintain vehicle control and proceed at a sensible speed past the obstruction/bend
Avoided sudden panic braking and kept the flow predictable for the approaching emergency driver
Emergency vehicle drivers need predictability and adequate sightlines to pass safely
3
Identify a safe location with good forward visibility, signal, and pull over smoothly
The emergency vehicle can overtake safely without risk of head-on collisions with oncoming traffic
Allows the emergency service to make rapid progress without endangering anyone

A driver must understand the impact of coasting on vehicle dynamics and safety. Match each coasting scenario with its primary vehicle control consequence according to The Highway Code.

Click a left item, then click its matching right item

Items

Selecting neutral when slowing down on the approach to a hazard
Holding the clutch down while descending a continuous steep gradient
Freewheeling while steering through a sharp corner or bend
Coasting when needing to respond promptly to an emerging hazard

Matches

Show answer & explanation

Answer

Matching pairs: Selecting neutral on approach to a hazard matches with elimination of engine braking; holding the clutch down on a steep gradient matches with rapid speed increase and brake fade; freewheeling through a corner matches with reduced stability and steering response; and coasting when responding to emerging hazards matches with delay in engaging the correct gear.
Rule 122 of The Highway Code clearly defines coasting as travelling in neutral or with the clutch pressed down. It reduces driver control because engine braking is eliminated, vehicle speed downhill increases rapidly, steering control and cornering grip are compromised, and selecting the appropriate gear in an emergency is delayed.

Step-by-Step Solution

1
Analyse the mechanical effect of selecting neutral when approaching a hazard.
Drivetrain is disconnected, which removes engine braking resistance.
Without engine braking, all decelerative force must come from the footbrake, increasing stopping distance if not managed properly.
2
Examine the dynamics of descending a steep gradient with the clutch depressed.
Gravity causes the vehicle to gain momentum rapidly.
Excessive reliance on the footbrake to counter gravity causes friction surfaces to overheat, leading to brake fade.
3
Assess vehicle cornering stability while freewheeling.
Chassis balance and steering precision are degraded.
Engaged drive helps maintain tyre contact patch grip and chassis equilibrium through bends.
4
Evaluate the driver's ability to react when an immediate speed adjustment is needed.
Extra time is required to match engine revs and engage the correct gear.
Coasting leaves the vehicle without immediate motive power during emergency manoeuvres.

Key Concept

Coasting removes engine braking, reduces steering stability, increases downhill speed, and causes delays in gear selection as outlined in Highway Code Rule 122.

Question 1077Question →

While following traffic on a rural single carriageway in good, dry conditions, you decide to verify that you are leaving an adequate safety gap. Which procedure should you follow to apply the two-second rule correctly?

Show answer & explanation

Answer: Choose a stationary roadside marker and ensure your car reaches it no earlier than two seconds after the vehicle ahead passes it

Answer

Choose a stationary roadside marker and ensure your car reaches it no earlier than two seconds after the vehicle ahead passes it
The correct method to verify separation distance is to pick a stationary roadside reference point (such as a sign, tree, or bridge) and note when the vehicle ahead passes it. Counting two full seconds ('one thousand and one, one thousand and two') before your own vehicle passes the same reference point ensures a safe following distance that automatically scales with your travelling speed.

Step-by-Step Solution

1
Identify a fixed stationary reference object along the roadside, such as an overhead sign, bridge, or lamp post.
A clear spatial benchmark is established ahead of both vehicles.
A fixed marker allows accurate measurement of the elapsed time between vehicles passing the same point.
2
Begin counting seconds ('one thousand and one, one thousand and two') the instant the rear of the vehicle ahead passes that reference object.
A time measurement of your separation gap is initiated.
The two-second interval accounts for both driver thinking time and vehicle braking distance under normal dry conditions.
3
Check whether your vehicle reaches the reference object before or after completing the count.
If you reach the object before finishing the two-second count, you are following too closely and must ease off the accelerator to extend the gap.
Ensures that your following distance dynamically scales with vehicle speed to prevent rear-end collisions.

Key Concept

The two-second rule provides a dynamic, speed-scaled separation margin in dry conditions by timing the interval between vehicles passing a fixed roadside point.

Question 1078Question →

What causes a car to aquaplane on a wet road surface?

Show answer & explanation

Answer: A layer of water building up between the tyres and the road surface

Answer

A layer of water building up between the tyres and the road surface
Aquaplaning occurs when a layer of surface water builds up between the tyres and the road surface faster than the tyre tread grooves can disperse it. This creates a cushion of water that lifts the tyres off the road, resulting in a loss of grip, steering, and braking control.

Step-by-Step Solution

1
Identify the physical mechanism of aquaplaning in wet conditions
Water accumulates under the tyres faster than the tread can clear it
When driving through standing water at speed, water pressure builds in front of and under the tyres
2
Determine the consequence on tyre-to-road contact
The tyres ride up on a cushion of water and lose direct contact with the road
This loss of road contact eliminates traction, steering control, and braking effectiveness

Key Concept

Aquaplaning occurs when surface water builds up between the tyres and the road surface, breaking direct tyre contact.

In Great Britain, a learner driver is legally permitted to drive on a motorway if they are accompanied by an Approved Driving Instructor (ADI) in a vehicle fitted with dual controls.

Show answer & explanation

Answer: True

Answer

True
The statement is true because UK law permits learner drivers to use motorways for driving lessons, provided they are accompanied by a fully qualified Approved Driving Instructor (ADI) in a car equipped with dual controls.

Step-by-Step Solution

1
Recall the legal provisions regarding provisional licence holders and motorway access in Great Britain.
Learner drivers are legally allowed on motorways under specific statutory conditions rather than being universally excluded.
Legislation enables learners to gain vital high-speed road experience prior to their practical driving test.
2
Check the specific conditions required for legal learner motorway driving.
The accompanying driver must be an Approved Driving Instructor (ADI), and the tuition car must have dual controls fitted.
Non-professional supervisors (such as family members or friends) are not permitted to accompany a learner on a motorway.
3

Click a left item, then click its matching right item

Items

Supervising a learner driver in a private vehicle
A learner driver driving on a motorway in England, Scotland, or Wales
Displaying green 'P' (probationary) plates after passing the practical driving test
Accumulating six or more penalty points within two years of passing the driving test

Matches

Show answer & explanation

Answer

Supervising a learner in a private vehicle matches being aged 21+ with 3 years full licence; motorway driving for learners matches requiring an ADI in a dual-control vehicle; green 'P' plates match being a voluntary measure for extra patience; and gaining 6 points in the first 2 years matches automatic licence cancellation requiring both tests to be retaken.
Each pairing correctly reflects statutory UK driving regulations: private learner supervision requires a 21-year-old supervisor with three years of full driving licence experience; motorway tuition for learners requires an ADI with dual controls; green 'P' plates are optional courtesy plates; and reaching six penalty points within two years invokes licence revocation under the New Drivers Act.

Step-by-Step Solution

1
Identify the minimum legal requirements for an accompanying driver supervising a learner.
The supervisor must be at least 21 years old and have held a full category B licence for at least 3 years.
Ensures that the supervisor has sufficient road experience and maturity to guide the learner safely.
2
Recall the legal criteria allowing learner drivers onto motorways in Great Britain.
Learners may only use motorways when accompanied by an Approved Driving Instructor in a car fitted with dual controls.
Protects motorway safety by ensuring professional dual-control intervention is available at high speeds.
3
Differentiate mandatory plate regulations from voluntary probationary indicators.
Green 'P' plates are optional in Great Britain and serve to encourage consideration from other road users.
Helps inexperienced drivers gain confidence without creating a statutory mandate.
4
Apply the provisions of the Road Traffic (New Drivers) Act regarding penalty thresholds.
Reaching six penalty points within two years of passing revokes the full licence completely.
Deters risky driving habits among newly qualified drivers during their probationary period.

Key Concept
