Question 42Question →

You are preparing to move off from a parking bay situated between two large, high-sided commercial vehicles on a busy, narrow high street. Your view of the road behind is severely obscured by the vehicle parked directly behind you. Which specific pre-manoeuvre observation strategy is critical before you initiate the manoeuvre?

Rely solely on the offside mirror to identify a safe gap, activating your indicator to warn approaching traffic before moving out decisively into the carriageway.

Focus your continuous observations on the vehicle parked immediately ahead, ensuring you apply sufficient steering lock to clear its rear bumper while pulling out.

Lean forward to maximize the angle of vision in your mirrors, followed by a thorough check over your right shoulder, and be prepared to edge out incrementally if visibility remains compromised.

Direct your primary observation towards the gaps between the parked vehicles to anticipate crossing pedestrians, as they present a more immediate static hazard than approaching traffic.

Show answer & explanation

Answer: Lean forward to maximize the angle of vision in your mirrors, followed by a thorough check over your right shoulder, and be prepared to edge out incrementally if visibility remains compromised.

Answer

Lean forward to maximize the angle of vision in your mirrors, followed by a thorough check over your right shoulder, and be prepared to edge out incrementally if visibility remains compromised.

When a driver's view is heavily obstructed by large vehicles, standard pre-manoeuvre observation routines must be actively adapted. Leaning forward physically alters the mirror's field of view to see further back, checking over the shoulder ensures no hazards are hidden in the immediate blind spot, and edging out slowly allows the driver to safely gain a better view of the carriageway before fully committing to the manoeuvre. This represents the safest and most comprehensive strategy for this specific hazard.

Step-by-Step Solution

Assess the visibility constraints caused by the high-sided vehicles.

Identify that standard mirror checks are insufficient due to the blocked rearward view.

Standard mirrors only reflect a specific angle, which is blocked by the large vehicle parked immediately behind.

Adjust physical position to expand the field of view.

Leaning forward alters the angle of reflection in the mirrors, revealing more of the road behind the obstructing van.

Changing the driver's head position dynamically increases the area visible through fixed mirrors, helping to see past blockages.

Perform a physical blind spot check.

Looking deeply over the right shoulder covers the area immediately next to the vehicle that mirrors cannot capture.

High-sided vehicles create massive blind spots that can easily conceal approaching vehicles, motorcycles, or cyclists.

Execute the manoeuvre with caution.

Edging out incrementally while continuing to observe allows for a safe abort if a previously hidden hazard is suddenly detected.

When visibility is permanently restricted until the vehicle is physically in the lane, moving out at a crawl is the only safe way to emerge.

Question 43Question →

According to the Highway Code, how does driving on a wet road surface affect your vehicle's overall stopping distance compared to dry conditions?

It is at least double the distance required on dry roads

It is up to ten times greater than on dry roads

It is reduced by half because water cools the brake components

It remains unchanged because modern braking systems fully eliminate water effects

Show answer & explanation

Answer: It is at least double the distance required on dry roads

Answer

It is at least double the distance required on dry roads

In wet weather, tyres have less grip on the road surface, which increases braking distance. The Highway Code explicitly states that overall stopping distances are at least double those required on dry roads.

Step-by-Step Solution

Identify the environmental condition and road surface state described

The vehicle is travelling on a wet road surface during or after rainfall.

Rainwater creates a film between the tyre tread and the road, significantly reducing tyre grip.

Apply the standard Highway Code rule for stopping margins on wet roads

Stopping distances are at least double the distance required on a dry road.

Lower surface friction increases the braking distance component of the overall stopping distance.

Although using a hands-free device while driving is not banned under specific handheld mobile phone regulations, a driver can still be prosecuted for driving without due care and attention if the device distracts them from safely controlling the vehicle.

True

False

Show answer & explanation

Answer: True

Answer

True

The statement is true because the law requires drivers to maintain proper control of their vehicle at all times. If using hands-free equipment causes distraction, delayed hazard reactions, or poor lane discipline, the driver can be prosecuted for driving without due care and attention.

Step-by-Step Solution

Examine the legal requirements regarding driver alertness and vehicle control under UK road traffic regulations.

Drivers must maintain proper control of their vehicle at all times under Highway Code Rule 149.

Safe driving requires constant scanning and immediate reaction to emerging road hazards.

Evaluate whether hands-free device usage is exempt from penalties related to driver distraction.

While hands-free usage is not penalised under the specific handheld mobile phone ban, careless driving laws still apply if driving performance deteriorates.

Cognitive distraction from conversations can divert mental focus and impair hazard perception.

According to The Highway Code, under good, dry road conditions and normal driver reaction times, what is the total stopping distance in metres for a vehicle travelling at $20\text{ mph}$ ( $32\text{ km/h}$ )?

Show answer & explanation

Answer: 12

Answer

The total stopping distance at

20\text{ mph}

under dry conditions is

12\text{ metres}

Under normal, dry driving conditions, The Highway Code specifies that at

20\text{ mph}

(

32\text{ km/h}

), thinking distance is

6\text{ metres}

and braking distance is

6\text{ metres}

. Summing these components gives an overall stopping distance of

12\text{ metres}

(

40\text{ feet}

Step-by-Step Solution

Determine the thinking distance component at

Question 46Question →

Under UK road safety law, it is illegal to fit a rear-facing child car seat in a front passenger seat protected by an active front airbag.

True

False

Show answer & explanation

Answer: True

Answer

True: UK law strictly prohibits fitting a rear-facing child car seat in a front seat protected by an active front airbag.

UK law makes it illegal to use a rear-facing child car seat in a front seat fitted with an active airbag because the violent inflation of the airbag can cause severe or fatal head and neck trauma to the child.

Step-by-Step Solution

Identify the child restraint configuration and the vehicle safety feature involved.

The statement describes placing a rear-facing child restraint in a passenger seat with an active front airbag.

Airbag deployment dynamics directly impact occupant restraints situated directly in front of them.

Apply the relevant UK Highway Code and legal safety requirements.

The law prohibits rear-facing child seats in front of active frontal airbags unless the airbag is deactivated.

The explosive deployment force can strike the back of the child seat and cause catastrophic injuries.

Question 47Question →

A vehicle equipped with a standard factory-fitted electronic engine immobiliser is fully protected against relay attacks when the keyless entry smart fob is stored unprotected inside a nearby house.

True

False

Show answer & explanation

Answer: False

Answer

False

The statement is false because relay theft intercepts and magnifies the wireless signal from an unprotected key fob inside a property. When this amplified signal reaches the car, the electronic immobiliser and keyless entry system recognize it as the genuine key, unlocking the doors and allowing the engine to start.

Step-by-Step Solution

Analyze how an electronic engine immobiliser verifies authorization

An immobiliser enables the engine to start once it receives the matching cryptographic transponder code from the paired smart key.

Understanding the wireless authentication process is necessary to evaluate potential system bypasses.

Examine how relay attack theft functions against keyless systems

Relay devices capture and boost the genuine radio signal between the vehicle and a key fob stored inside a nearby building.

Determines whether an immobiliser receives the valid signal required to permit operation.

Assess whether the immobiliser prevents vehicle theft during a relay attack

Because the authentic signal is relayed, the immobiliser recognizes the key as authorized and disarms, allowing the vehicle to be unlocked and driven away.

Concludes that a standard factory immobiliser alone does not protect against relay theft without physical signal-blocking measures.

Question 48Question →

Approaching a signal-controlled intersection marked with a yellow box, you intend to turn right. The traffic light is green, your intended exit road is completely clear, but oncoming traffic is actively flowing towards the junction. An oncoming motorist briefly flashes their headlights. Which course of action should you take?

Remain stationary behind the stop line until all oncoming traffic passes and the entire intersection is clear.

Drive into the yellow box and wait for a safe gap in oncoming traffic before completing the turn.

Turn immediately across the oncoming lane, treating the flashed headlights as an invitation that gives you priority.

Move into the yellow box and turn immediately behind a passing vehicle without checking your offside blind spots for filtering traffic.

Show answer & explanation

Answer: Drive into the yellow box and wait for a safe gap in oncoming traffic before completing the turn.

Answer

Drive into the yellow box and wait for a safe gap in oncoming traffic before completing the turn.

According to Highway Code Rule 174, drivers must not enter a box junction unless their exit road is clear. However, there is a specific exception: you may enter the box and wait when you want to turn right and are only prevented from doing so by oncoming traffic or other vehicles waiting to turn right. Because the intended exit road is clear and the traffic signal is green, moving into the box to wait for a safe gap is the correct procedure. Flashing headlights from oncoming drivers should never be taken as a signal of priority.

Step-by-Step Solution

Assess the junction layout and exit road status

Confirm that the traffic signal is green and the right-turn exit road is clear of obstructions.

Highway Code Rule 174 permits entering a box junction if turning right and the exit lane is clear.

Move forward into the junction and position within the yellow box

The vehicle is positioned safely to execute the turn once oncoming traffic clears.

Waiting inside the box prevents unnecessary obstruction behind and allows prompt clearance when a gap appears.

Evaluate oncoming traffic and ignore assumptions about flashing headlights

Do not treat flashed headlights as priority; wait for a genuine, safe gap while checking for filtering road users.

Highway Code Rule 110 states flashing headlights only let other road users know you are there.

Question 49Question →

An overhead gantry sign indicates that your current lane is closed ahead due to roadworks, requiring you to move into the adjacent offside lane. Arrange the following actions in the correct chronological order to complete this lane change safely according to the Highway Code.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence begins with checking the interior and offside mirrors, followed by checking the offside blind spot, then signalling right in good time, smoothly steering into the target lane, and finally cancelling the indicator while establishing a safe following distance.

Safe lane discipline and positioning when responding to an overhead lane closure strictly follow the Mirrors–Signal–Manoeuvre routine. First, the driver must check interior and door mirrors to understand traffic flow in the target lane. Second, a quick shoulder check must be made to cover the blind spot. Third, a right signal is applied in good time to warn other drivers. Fourth, the driver moves smoothly into the available gap. Finally, the indicator is cancelled and appropriate following distances are restored.

Step-by-Step Solution

Check rear-view and offside exterior mirrors.

Assesses the speed, distance, and approach rate of vehicles in the adjacent offside lane.

Highway Code Rule 133 requires all manoeuvres to begin with mirror observation to evaluate surrounding traffic.

Perform a quick shoulder check into the offside blind spot.

Ensures no vehicle, cyclist, or motorcyclist is positioned in the unviewable area alongside your vehicle.

Mirrors alone do not eliminate blind spots; a direct glance confirms it is safe before signalling.

Apply the right-turn direction indicator.

Gives clear, unambiguous notice to drivers behind and in the adjacent lane of your planned move.

Signalling must precede the physical lane change so other road users have sufficient time to react and accommodate the merge.

Steer smoothly across into the open lane.

Positions your vehicle safely in the new lane without causing disruption or sudden braking to following traffic.

Executes the manoeuvre into an identified, safe gap in accordance with lane discipline rules.

Cancel the indicator and re-establish a safe separation gap.

Prevents misleading following drivers and ensures the required two-second gap is maintained.

Leaving an indicator running after completing a lane change creates confusion and potential hazards.

Question 50Question →

You are driving along a rural road in patchy fog where visibility temporarily drops below 100 metres (328 feet). After switching on your fog lights, you enter a clear stretch where visibility returns to normal. What should you do regarding your fog lights?

Leave them switched on in case you encounter another sudden patch of fog ahead

Switch them off promptly to avoid dazzling other road users and obscuring your brake lights

Leave them on and switch your headlights to main beam to improve forward vision

Keep them on but increase your following distance from the vehicle ahead

Show answer & explanation

Answer: Switch them off promptly to avoid dazzling other road users and obscuring your brake lights

Answer

Switch them off promptly to avoid dazzling other road users and obscuring your brake lights

Under UK Highway Code Rule 236, you must switch off your front and rear fog lights as soon as visibility improves beyond 100 metres (328 feet). High-intensity rear fog lights can dazzle drivers travelling behind you and make your brake lights much harder to distinguish.

Step-by-Step Solution

Assess the current road visibility against the legal threshold.

Visibility has improved to well over 100 metres (328 feet).

Under UK Highway Code Rules 226 and 236, fog lights are legally permitted only when visibility is seriously reduced to 100 metres or less.

Deactivate front and rear fog lights once the fog has cleared.

The vehicle returns to standard lighting without excessive rear glare.

High-intensity rear fog lights dazzle following drivers and make it difficult for them to see when you apply the brakes.

Key Concept

UK Highway Code Rule 236 states that drivers must switch off front and rear fog lights when visibility improves beyond 100 metres (328 feet) because they dazzle other road users and can obscure brake lights.

Question 51Question →

While travelling on an unlit country road at night, you find yourself trailing a motorcyclist. Why is it important to drop back and maintain a larger separation distance than usual?

To allow you to move closer into the rider's blind spot so they notice your presence

To prevent your headlights from dazzling the rider in their mirrors while giving you a clearer view ahead

To enable you to fixate entirely on the motorcycle's rear lamp rather than scanning the wider road environment

Because larger separation margins are only necessary when wet weather doubles the required stopping distance

Show answer & explanation

Answer: To prevent your headlights from dazzling the rider in their mirrors while giving you a clearer view ahead

Answer

To prevent your headlights from dazzling the rider in their mirrors while giving you a clearer view ahead

Maintaining an increased following distance behind a motorcyclist on an unlit road ensures your headlights do not reflect blinding glare into the rider's rear-view mirrors. Furthermore, hanging back provides you with an unobstructed view of the carriageway ahead beyond the motorcycle's narrow profile, giving both road users greater reaction time.

Step-by-Step Solution

Identify the environmental and road user risks

Unlit rural roads offer limited visibility, and motorcyclists have minimal physical protection and rely heavily on clear vision through their mirrors and visor.

Vulnerable road users are disproportionately affected by driver actions in dark conditions.

Evaluate the impact of headlight positioning and following distance

Trailing too closely causes headlights to bounce off the rider's mirrors, causing temporary blindness, while dropping back eliminates glare and provides a wider view past the narrow vehicle.

Maintaining an enhanced safety margin preserves the rider's vision and increases your reaction time to potential hazards.

Match each smart motorway signal or feature to its correct legal meaning and driver requirement.

Click a left item, then click its matching right item

Show answer & explanation

Answer

Each signal matches its specific legal obligation: a Red 'X' indicates a mandatory lane closure; a red ring denotes a legally enforceable speed limit; amber flashing lights signify an advisory speed recommendation; and an Emergency Area provides refuge solely for breakdowns and emergencies.

On smart motorways, overhead signals communicate enforceable traffic management rules. A Red 'X' strictly prohibits driving in that lane; numbers within a red circle set a mandatory statutory limit; flashing amber lights without a red ring provide advisory warnings; and Emergency Areas are reserved exclusively for breakdowns and emergencies.

Step-by-Step Solution

Differentiate between mandatory regulatory signals (red ring or Red 'X') and advisory warnings (amber flashing lights).

Identify that red circles and red crosses impose strict legal prohibitions and statutory requirements under the Highway Code.

Red markings on overhead motorway gantries denote statutory requirements enforced by speed and lane compliance cameras.

Correlate designated refuge infrastructure with its permitted usage conditions.

Connect Emergency Areas (EAs) with strict emergency/breakdown criteria.

Emergency areas replace the continuous hard shoulder and must remain unobstructed for stranded vehicles and emergency responders.

Treat each mini-roundabout separately and give way to traffic approaching from your right at each one

Proceed immediately across both roundabouts if a driver on the intermediate approach flashes their headlights

Accelerate continuously through the second roundabout without checking mirrors or blind spots

Show answer & explanation

Answer: Treat each mini-roundabout separately and give way to traffic approaching from your right at each one

Answer

Treat each mini-roundabout separately and give way to traffic approaching from your right at each one

According to The Official Highway Code (Rule 188), at double mini-roundabouts you must treat each roundabout separately and give way to traffic approaching from your right at each one.

Step-by-Step Solution

Identify the junction type as a double mini-roundabout upon approach

Recognise that the layout consists of two distinct, connected mini-roundabouts rather than a single large island

Allows the driver to prepare for multiple give-way lines in close succession

Apply Highway Code Rule 188 at the first mini-roundabout

Give way to traffic approaching from the right and enter when safe

Standard UK roundabout priority applies at every individual roundabout entrance

Assess the second mini-roundabout independently upon reaching its give-way line

Question 54Question →

You are driving on a road during daylight hours. In which situation are you officially permitted to flash your vehicle's headlights?

To inform another driver that you are giving way to them

To warn other road users of your presence

To express frustration at another driver's mistakes

To signal to oncoming vehicles that a hazard has cleared

Show answer & explanation

Answer: To warn other road users of your presence

Answer

Flashing headlights should only be used to warn other road users of your presence.

Under Rule 110 of the Highway Code, you must only flash your headlights to let other road users know you are there. It serves the same alerting function as sounding your horn in daylight.

Step-by-Step Solution

Recall the official Highway Code rule regarding the use of flashing headlights (Rule 110).

Headlights must only be flashed to let other road users know you are there.

Official road rules establish a single universal meaning for flashing headlights to prevent misunderstandings.

Evaluate the given choices against the statutory rule.

Alerting others of your presence is the only permitted purpose.

Using headlights to convey priority, show anger, or signal unofficial messages can lead to misinterpretation and serious collisions.

Question 55Question →

You are driving in Lane 2 (the middle lane) of a three-lane motorway and plan to leave at the next junction. In what order should you carry out the following actions to exit safely while observing correct lane discipline?

Drag items to arrange them in the correct order

Show answer & explanation

Answer

Move into Lane 1 well ahead of the junction using the MSM routine, signal left at the countdown markers while maintaining speed, enter the deceleration lane smoothly without harsh braking on the carriageway, and then decelerate once fully inside the exit lane.

Under Highway Code Rules 272 and 273, drivers intending to exit a motorway must get into the left-hand lane (Lane 1) well in advance of the junction. You should signal left as you approach the countdown markers while maintaining cruising speed. Steer smoothly into the deceleration lane before applying the brakes, ensuring all significant deceleration occurs within the slip road rather than on the live carriageway.

Step-by-Step Solution

Check mirrors and move into Lane 1 (the left-hand lane) well before reaching the junction.

The vehicle is correctly positioned in the leftmost lane ahead of the exit.

The Highway Code requires drivers to move into the left-hand lane in good time rather than attempting last-minute lane changes near the exit.

Signal left in good time, using the 300-yard countdown marker to time the indicator while maintaining carriageway speed.

Surrounding road users are alerted to your intention to leave the motorway.

Signalling early while maintaining a steady cruising speed prevents following drivers from misinterpreting your intentions or braking unnecessarily.

Steer smoothly across into the deceleration lane without harsh braking on the live carriageway.

The vehicle enters the slip road safely without causing a hazard to traffic continuing on the main carriageway.

Braking on the live motorway before entering the slip road creates severe rear-end collision risks for trailing high-speed traffic.

Apply the brakes smoothly once completely within the deceleration lane to bring the speed down for the slip road.

The vehicle reaches an appropriate speed for the slip road bends or end-of-ramp junction.

Deceleration lanes are specifically designed to absorb braking off the main high-speed carriageway.

Key Concept

Motorway lane discipline when exiting requires establishing position in Lane 1 well before the junction, signalling at the countdown markers, and delaying braking until fully within the deceleration lane.

You are driving along a single carriageway road and observe that the vehicle behind is following far too closely. Which TWO actions should you take to safely manage this hazard? (Select TWO answers)

Select all that apply

Ease off the accelerator gradually to increase the separation distance ahead of your car

Brake sharply to shock the driver behind into increasing their following distance

Allow extra time and space to react smoothly if you need to slow down or stop

Accelerate beyond the legal speed limit to outrun the close-following vehicle

Show answer & explanation

Answer: Ease off the accelerator gradually to increase the separation distance ahead of your car; Allow extra time and space to react smoothly if you need to slow down or stop

Answer

Ease off the accelerator gradually to increase the separation distance ahead of your car, and allow extra time and space to react smoothly if you need to slow down or stop.

When a driver follows too closely behind, you cannot control their distance, but you can control the safety margin ahead of your own vehicle. Gradually easing off the accelerator expands the gap in front of you. This ensures you have plenty of time and space to anticipate hazards and brake gently, preventing the tailgater from colliding with the back of your car.

Step-by-Step Solution

Assess the risk created by the tailgating vehicle

Recognise that the vehicle behind does not have enough stopping distance to react to sudden braking

Tailgaters compromise the rear safety margin, transferring the responsibility of maintaining overall safety space to the leading driver.

Adjust the forward safety gap smoothly

Gently ease off the accelerator to open up a larger gap to any vehicle or hazard ahead

An increased forward gap ensures all upcoming decelerations can be progressive and smooth, eliminating the need for abrupt braking.

Question 57Question →

On which type of road surface can an Anti-lock Braking System (ABS) cause your vehicle's stopping distance to be longer during emergency braking?

Smooth, dry asphalt in warm daylight conditions

A standard tarmac carriageway wet with light rain

A road surface covered in loose gravel or deep snow

A newly resurfaced motorway with high-grip porous tarmac

Show answer & explanation

Answer: A road surface covered in loose gravel or deep snow

Answer

A road surface covered in loose gravel or deep snow

On loose surfaces such as gravel, loose earth, or snow, an Anti-lock Braking System (ABS) prevents the wheels from locking. While this ensures the driver retains steering control, the rolling wheels ride on top of the loose material instead of locking up and pushing a wedge of loose material in front of them, which can result in an increased stopping distance.

Step-by-Step Solution

Analyze how an Anti-lock Braking System (ABS) functions on standard versus loose road surfaces.

ABS prevents road wheels from locking by rapidly pulsing brake pressure, keeping tyres rolling to maintain directional steering control.

Understanding the physical mechanism of wheel rotation versus wheel locking is essential for recognizing surface-specific limitations.

Evaluate the effect of loose surface material (gravel, snow) when wheels continue to rotate under ABS control.

Locked wheels naturally dig into loose gravel or snow and build a wedge of material in front of the tyres to help halt the vehicle, whereas ABS keeps the wheels rolling on top of the loose layer.

This rolling action prevents the wedge effect from forming, which can increase the overall stopping distance despite maintaining steering ability.

Key Concept

ABS operation preserves steering control under heavy braking, but on loose surfaces such as gravel or snow, stopping distances may be extended.

Under UK road traffic law, a driver is permitted to hold and interact with a handheld mobile phone while stopped at red traffic lights, provided the vehicle's engine has temporarily cut out due to an automatic start-stop system.

True

False

Show answer & explanation

Answer: False

Answer

False. Drivers are strictly prohibited from holding and using a mobile phone while waiting at traffic lights, even when the engine has stopped automatically.

The statement is false because UK Highway Code Rule 149 strictly prohibits holding and using a mobile phone or handheld interactive device while driving. This legal restriction applies fully when waiting at red traffic lights or queuing in traffic, even if the engine has temporarily turned off via an automatic start-stop system. Handheld phone usage is only permitted when safely and lawfully parked with the engine switched off, or in a genuine emergency making a 999/112 call where stopping safely is impossible.

Step-by-Step Solution

Determine whether waiting at red traffic lights with an automatic start-stop engine constitutes active driving.

The vehicle is stationary within the flow of live traffic, meaning the driver is still legally driving.

Temporary stops at signals or junctions do not mean the journey has concluded or that the vehicle is parked.

Apply UK Highway Code Rule 149 and relevant road traffic regulations regarding handheld device usage.

Holding and interacting with a handheld mobile phone remains completely prohibited in this situation.

The ban on handheld devices applies continuously throughout driving, including when stationary in traffic queues and at red lights.

Under UK road traffic law, a child aged 3 years or older is legally permitted to travel in the rear seat of a car using an adult seatbelt if a suitable child restraint is unavailable during an unexpected emergency over a short distance.

True

False

Show answer & explanation

Answer: True

Answer

True — UK regulations allow a child aged 3 or older to use an adult seatbelt in the rear seat during an unexpected emergency over a short distance if no child seat is available.

The statement is true because UK road traffic regulations and the Highway Code make specific provision for unexpected emergencies over a short distance, allowing children aged 3 years or older to use an adult seatbelt in the rear seat when a child seat is unavailable.

Step-by-Step Solution

Identify the standard UK child restraint requirement for children under 135 cm and under 12 years old.

The general rule mandates the use of an approved child car seat suitable for the child's weight and height.

Establishing the baseline legal requirement is necessary before evaluating statutory exceptions.

Evaluate the statutory exceptions to child restraint requirements under UK road traffic law.

Exceptions exist for children aged 3 and above: travelling in licensed taxis/private hire vehicles, unexpected short-distance emergencies, and when two fitted child seats prevent fitting a third.

UK legislation (The Motor Vehicles Wearing of Seat Belts Regulations) specifies narrow conditions where an adult belt may be used in the rear.

Determine if the scenario satisfies all statutory conditions (child aged 3+, rear seat, unexpected emergency, short distance).

All conditions are met, confirming the legality of the arrangement.

The exemption strictly applies only in the rear seat and never in the front passenger seat or for children under 3 years old.

Question 60Question →

When driving in poor weather conditions, which driver action is most likely to cause a vehicle to skid?

Increasing the gap behind the vehicle in front to double the standard following distance

Making sudden or harsh steering and braking inputs

Maintaining tyre tread depth significantly above the legal minimum requirement

Changing down to a lower gear smoothly to reduce vehicle speed gradually

Show answer & explanation

Answer: Making sudden or harsh steering and braking inputs

Answer

Making sudden or harsh steering and braking inputs is the action most likely to cause a skid.

Skidding is almost always caused by driver error. Making sudden, violent, or harsh inputs with the brakes, steering wheel, or accelerator forces the tyres beyond their grip limits, causing them to slide across the road surface.

Step-by-Step Solution

Identify the primary physical cause of a skid

A skid occurs when the physical demand placed on the tyres exceeds the available grip between the tyres and the road surface.

Tyres have a finite threshold of adhesion, which is further reduced in poor weather.

Evaluate the effect of sudden control inputs versus smooth driving techniques

Sudden or aggressive actions (heavy braking, sharp steering, abrupt throttle application) demand immediate grip shifts that break traction.

Smooth, progressive control inputs distribute forces gradually and maintain tyre grip.

Select the option describing harsh control inputs

Harsh steering and braking inputs are identified as the direct driver cause of skidding.

Driver error through abrupt control inputs is the leading cause of skidding on UK roads.

Key Concept

Skids are primarily caused by driver error involving excessive speed or sudden, harsh control inputs that exceed available tyre grip.
