Determine whether the following statement is true or false: While the Highway Code strictly prohibits leaving a vehicle's engine running unnecessarily on a public road to minimise exhaust emissions and noise pollution, it provides an explicit legal exemption that permits the engine to remain running if the vehicle is stationary in a traffic queue.

True

False

Show answer & explanation

Answer: True

Answer

The statement is true, as the Highway Code provides a specific exception for vehicles stationary in traffic.

The statement is entirely correct. Rule 123 of the Highway Code creates a legal balance between environmental protection and practical driving. While it makes unnecessary engine idling an offence to reduce exhaust emissions and noise pollution, it deliberately exempts vehicles that are stationary in traffic, recognising that drivers need to remain ready to move as the queue advances.

Step-by-Step Solution

Analyze the general regulation regarding engine idling.

The Highway Code strictly states that a driver MUST NOT leave a vehicle engine running unnecessarily while stationary on a public road.

This establishes the baseline environmental and noise abatement regulation.

Identify any legal exemptions to this general rule.

Rule 123 explicitly states that it is permissible to leave the engine running if the vehicle is stationary in traffic or for diagnosing vehicle faults.

Understanding exceptions is critical for applying the law correctly in real-world scenarios.

Compare the identified rules with the provided statement.

The statement accurately reflects both the strict prohibition on unnecessary idling and the specific exemption for traffic queues.

This confirms the statement is entirely factually correct.

Question 662Question →

A driver's thinking distance is the distance covered from the moment a hazard is first spotted until the brakes are applied. Match each factor to the specific way it increases thinking distance.

Click a left item, then click its matching right item

Show answer & explanation

Answer

The correct matching connects higher speed to covering more metres per second, phone distraction to diverted attention, tiredness to slowed sensory reflexes, and drowsy medication to pharmaceutical nervous system impairment.

Thinking distance depends purely on the driver's reaction time and vehicle speed. Speed increases metres travelled per second; distractions delay hazard spotting; fatigue slows cognitive processing; and sedating medication depresses physical and mental reflexes.

Step-by-Step Solution

Identify how vehicle speed affects thinking distance.

Speed determines distance covered per unit of reaction time.

At 60 mph compared to 30 mph, the vehicle travels twice as far in the same reaction interval.

Examine driver cognitive distractions such as hands-free phone conversations.

Distraction diverts mental attention and delays hazard recognition.

The driver takes longer to mentally register that a hazard is developing.

Assess the physical effect of fatigue.

Tiredness impairs alertness and slows neurological response.

A fatigued brain requires more time to process visual stimuli and command physical action.

Evaluate medicinal side-effects.

Sedating medication depresses central nervous system reflexes.

Drowsiness directly lengthens the physical time taken to move a foot to the brake pedal.

Key Concept

Thinking distance is directly influenced by driver reaction time (affected by tiredness, distraction, and drugs/medication) and travelling speed (which increases distance covered during that reaction time).

Question 663Question →

After completing an overnight work shift, a motorist is travelling along a clear bypass when an unexpected hazard appears. Which factor will prolong the distance the vehicle travels before the driver physically presses the brake pedal?

Severely worn brake pads reducing mechanical braking efficiency

Standing surface water on the road reducing tyre grip

Driver tiredness and reduced cognitive reaction speed

Increased vehicle weight from carrying multiple adult passengers

Show answer & explanation

Answer: Driver tiredness and reduced cognitive reaction speed

Answer

Driver tiredness and reduced cognitive reaction speed

Thinking distance is the distance a vehicle travels during the driver's reaction time—from the instant a hazard is perceived until the driver actually applies the footbrake. Driver tiredness significantly slows neural reaction speed, meaning the vehicle covers more ground before braking begins.

Step-by-Step Solution

Identify the specific phase of stopping distance described in the question stem

The phrase 'distance the vehicle travels before the driver physically presses the brake pedal' defines the thinking distance (reaction distance).

Total stopping distance is split into thinking distance (hazard detection to brake press) and braking distance (brake press to full stop).

Analyze which variables affect thinking distance versus braking distance

Thinking distance depends strictly on vehicle speed and driver reaction time (governed by fatigue, drugs, alcohol, illness, or distraction), whereas braking distance depends on tyres, brakes, road surface, and vehicle weight.

Mechanical components and road adhesion only operate once the braking system has been physically engaged.

Evaluate the provided options against the identified thinking distance mechanism

Driver fatigue directly impairs alertness and doubles or triples mental processing time, directly extending thinking distance.

Brake wear, standing water, and passenger weight are physical/mechanical factors that only influence braking distance.

Key Concept

Thinking distance is the distance travelled while reacting to a hazard before applying the brakes, and it is strictly determined by vehicle speed and driver reaction time.

Question 664Question →

You are approaching a roundabout and observe a horse and rider ahead in the left-hand lane signalling right. What action should you take?

Sound the horn to warn the rider that they are in the wrong lane for making a right turn

Flash the headlights to signal oncoming traffic to give way to the horse rider

Stay well back and allow the rider space and time to negotiate the roundabout

Overtake on the right immediately before the roundabout entry, assuming you will clear the rider's blind spot quickly

Show answer & explanation

Answer: Stay well back and allow the rider space and time to negotiate the roundabout

Answer

Stay well back and allow the rider space and time to negotiate the roundabout.

Under The Highway Code, horse riders and cyclists approaching or navigating a roundabout may decide to stay in the left-hand lane even when they intend to turn right. This positioning keeps them away from faster-moving traffic lanes. Drivers must anticipate this, keep well back at a respectful distance, and give them ample time and room to complete the turn safely.

Step-by-Step Solution

Assess the positioning and vulnerability of the equestrian ahead.

Recognise that under The Highway Code, horse riders and cyclists are permitted to keep to the left-hand lane of a roundabout even when turning right to avoid crossing lanes of moving traffic.

Vulnerable road users adopt this position for their own safety and stability.

Adopt a considerate following position and adjust vehicle control.

Hold back at a safe distance, keep engine revs low, and wait patiently without sounding the horn or flashing headlights.

Horses are easily frightened by sudden noises, flashing lights, or close-passing vehicles.

Answer: $38\text{ metres}$ ( $125\text{ feet}$ )

Answer

38\text{ metres}

(

125\text{ feet}

)

According to The Official Highway Code, a car travelling at

50\text{ mph}

(

80\text{ km/h}

) has a total stopping distance of

53\text{ metres}

(

175\text{ feet}

). This total consists of a thinking distance of

(

125\text{ feet}

Step-by-Step Solution

Recall the components of total stopping distance at

50\text{ mph}

(

80\text{ km/h}

Total Stopping Distance = Thinking Distance + Braking Distance

Overall stopping distance is always divided into the driver's reaction phase and the vehicle's deceleration phase.

Question 666Question →

You are driving a Large Goods Vehicle (LGV) and intend to turn left at a tight urban junction. To negotiate the corner without the rear wheels mounting the pavement, you have positioned the vehicle slightly to the right of your lane. How must you manage your blind spots during this specific manoeuvre?

Continuously monitor your left-hand mirrors throughout the entire manoeuvre, actively checking for cyclists who may filter into the large near-side blind spot created by your wide road position.

Perform a comprehensive left mirror check before moving, but once the vehicle is in motion, maintain your focus exclusively ahead to ensure the cab clears oncoming traffic.

Rely entirely on the vehicle's acoustic warning system and sensors to alert you to pedestrians or cyclists in your blind spot, as direct visual checks become severely restricted once the cab pivots.

Assume that moving the cab to the right automatically closes off the space on the left, making it physically impossible for cyclists to enter your near-side blind spot while you turn.

Show answer & explanation

Answer: Continuously monitor your left-hand mirrors throughout the entire manoeuvre, actively checking for cyclists who may filter into the large near-side blind spot created by your wide road position.

Answer

You must continuously monitor your left-hand mirrors throughout the entire manoeuvre, actively checking for cyclists who may filter into the large near-side blind spot created by your wide road position.

The correct answer emphasizes the absolute necessity of continuous visual monitoring using left-hand mirrors. When an LGV swings right to turn left, it opens a large gap on the near-side. Cyclists may mistakenly believe the vehicle is turning right or leaving them room to pass straight ahead. Because the blind spot is vast and the situation changes rapidly as the vehicle pivots, continuous mirror checks are the only way to detect a vulnerable road user before the trailer's rear wheels track across their path.

Step-by-Step Solution

Analyze the hazard presented by the LGV's road position.

Moving to the right to prepare for a left turn creates a large, inviting gap on the vehicle's left (near-side).

Vulnerable road users, particularly cyclists, may misinterpret this road positioning as an opportunity to filter up the inside of the vehicle.

Identify the specific blind spot risk associated with the vehicle.

The sheer length and height of the LGV create a massive near-side blind spot that can completely hide entire vehicles, cyclists, and pedestrians.

The driver's direct field of vision is severely restricted by the cab structure and the length of the trailer body.

Determine the correct observational procedure for the driver.

The driver must use continuous mirror checks on the left side before and throughout the entire turning process.

Because the blind spot is vast and dynamic, a single check before turning is insufficient to guarantee safety as cyclists can quickly move into the danger zone.

Key Concept

Question 667Question →

You are driving in the middle lane of a three-lane motorway and become engaged in a highly stressful conversation using a legally compliant, fully built-in hands-free system. The intense mental distraction severely reduces your situational awareness. According to the UK Highway Code, which statement accurately reflects your legal position and driving responsibilities in this situation?

Even though the hands-free equipment itself is legal, you can be prosecuted for driving without due care and attention because the cognitive distraction has impaired your proper control of the vehicle.

You cannot be prosecuted for the distraction provided you lock your focus strictly on the vehicle directly ahead to maintain a constant separation distance.

The hands-free conversation is legally permissible as long as you deliberately remain in the middle lane to avoid the complexity of returning to the left-hand lane.

You are legally protected from prosecution if you depress the clutch to coast, ensuring your speed naturally decreases while you finish the stressful call.

Show answer & explanation

Answer: Even though the hands-free equipment itself is legal, you can be prosecuted for driving without due care and attention because the cognitive distraction has impaired your proper control of the vehicle.

Answer

The correct answer accurately reflects UK Highway Code Rule 150. While the specific act of using a hands-free device is not inherently illegal, the law demands that drivers remain in proper control of their vehicle at all times. If a hands-free conversation causes significant cognitive distraction (mental overload) resulting in a drop in driving standards, the driver can absolutely be prosecuted for careless driving or driving without due care and attention.

Step-by-Step Solution

Analyze the legality of the equipment being used.

The scenario states the driver is using a fully built-in, compliant hands-free system.

This establishes that the specific offence of holding a mobile phone is not occurring.

Evaluate the driver's cognitive state and situational awareness.

The driver is experiencing severe mental distraction and reduced awareness due to the stressful call.

The law distinguishes between physical control (hands on the wheel) and cognitive control (attention on the road).

Apply Highway Code Rule 150 regarding overall vehicle control.

The driver is failing to exercise proper control and attention, leaving them liable for prosecution for driving without due care and attention.

Using hands-free equipment is not a blanket legal defence if the conversation distracts you from driving safely.

Question 670Question →

When driving through busy urban traffic with frequent queues and traffic signals, which driving technique will reduce both fuel consumption and exhaust emissions most effectively?

Depressing the clutch pedal and coasting in neutral towards red traffic lights to keep engine revs at idle

Focusing closely on the vehicle immediately ahead and accelerating promptly to close gaps in traffic

Anticipating road conditions well ahead to maintain a steady rolling pace and avoid coming to a complete standstill

Reducing tyre pressures below manufacturer specifications to increase surface contact and improve stop-start traction

Show answer & explanation

Answer: Anticipating road conditions well ahead to maintain a steady rolling pace and avoid coming to a complete standstill

Answer

Anticipating road conditions well ahead to maintain a steady rolling pace and avoid coming to a complete standstill

Anticipating changes in traffic and signal phases ahead allows a driver to adjust speed smoothly and keep the vehicle rolling. Preserving rolling momentum avoids the substantial energy and fuel consumption required to move a stationary vehicle away in first gear.

Step-by-Step Solution

Analyse the energy demands of stop-start urban driving

Recognised that accelerating a vehicle from a complete stop demands significantly more kinetic energy and fuel than sustaining moderate rolling momentum.

Overcoming static inertia requires low gears and high engine torque, resulting in peak fuel burn and exhaust emissions.

Evaluate eco-safe driving techniques endorsed by the DVSA

Identified that scanning ahead allows the driver to adjust speed early using engine braking and deceleration rather than abrupt braking.

Maintaining smooth progression through anticipation eliminates harsh throttle applications and unnecessary stops.

While driving through a busy town centre, an impatient driver overtakes you recklessly, cuts in closely, and brakes abruptly while making aggressive hand gestures. Which action should you take to diffuse the situation safely?

Flash your headlights repeatedly to signal your disapproval of their reckless driving

Drop back to restore a safe separation distance and ignore the aggressive behaviour

Fixate your gaze directly on their rear bumper to monitor their exact braking distance

Depress the clutch pedal and coast to reduce your speed without displaying brake lights

Show answer & explanation

Answer: Drop back to restore a safe separation distance and ignore the aggressive behaviour

Answer

Drop back to restore a safe separation distance and ignore the aggressive behaviour

When faced with aggressive driving or road rage, the safest and most effective response is to stay calm, avoid confrontation, and drop back to increase your following distance. Allowing extra space gives you time to react if the driver behaves erratically and removes you from the immediate conflict.

Step-by-Step Solution

Assess the immediate risk and resist any impulse to react or retaliate

Emotional control is maintained, preventing immediate escalation of road rage

Retaliating with gestures, sounds, or aggressive driving intensifies confrontation and increases collision risk

Gently decelerate to create an increased safety gap behind the aggressive vehicle

A safe following distance is established, providing adequate thinking and stopping room

Aggressive drivers often drive erratically; giving them ample space minimizes danger and removes you from direct conflict

You are carrying passengers of various ages in your car. Who is legally responsible for making sure that a 13-year-old passenger wears a seatbelt or approved child restraint during the journey?

The 13-year-old passenger

The driver of the vehicle

The parent or legal guardian accompanying the journey

The registered keeper of the vehicle

Show answer & explanation

Answer: The driver of the vehicle

Answer

The driver of the vehicle is legally responsible for ensuring the 13-year-old passenger is properly restrained.

Under UK traffic law and the Highway Code, the driver of the vehicle is legally responsible for ensuring that any passenger under the age of 14 is securely fastened in an approved child restraint or adult seatbelt. Passengers only become personally liable under the law once they reach 14 years of age.

Step-by-Step Solution

Identify the passenger's age and the legal liability threshold under UK road traffic law.

The passenger is 13 years old, which is under the 14-year legal threshold.

UK traffic law establishes age 14 as the boundary where responsibility transfers from the driver to the passenger.

Determine who holds the legal duty for passengers under 14 years of age.

The driver of the vehicle is legally responsible.

The Highway Code explicitly states that drivers must ensure all children under 14 wear an appropriate seatbelt or approved child restraint.

Drivers significantly influence both fuel economy and tailpipe emissions through their operational choices and vehicle maintenance. Match each vehicle condition or driving state to its direct physical and environmental consequence.

Click a left item, then click its matching right item

Show answer & explanation

Answer

Short journeys with a cold engine pair with catalytic converter under-temperature and rich fuel mixtures; continuous electrical usage pairs with increased alternator mechanical drag; driving at 70 mph versus 50 mph pairs with approximately 30% higher fuel consumption from aerodynamic drag; under-inflated tyres pair with increased rolling resistance and accelerated shoulder wear.

Each driving state links directly to a fundamental physical or chemical process in vehicle operation: cold starts prevent emission catalysts from converting toxic gases; electrical draw creates parasitic torque load via the alternator; aerodynamic resistance increases with the square of speed on open roads; and under-inflation increases tyre deformation and rolling resistance.

Step-by-Step Solution

Evaluate engine thermal efficiency and exhaust aftertreatment behavior during short trips

Cold engines require rich mixtures and emit unburned hydrocarbons and carbon monoxide before the catalytic converter reaches light-off operating temperature.

Exhaust catalysts require high operating heat to initiate chemical oxidation and reduction reactions.

Assess auxiliary electrical power generation mechanics

High electrical draw increases the magnetic resistance inside the alternator, which directly demands more rotational torque from the crankshaft.

Energy conservation dictates that electrical power consumed must come from fuel energy via the engine-driven alternator.

Apply fluid dynamics principles to highway speed changes

Air resistance rises exponentially (

F_{\text{drag}} \propto v^2

), making 70 mph significantly less fuel-efficient (approximately 30% higher consumption) than 50 mph.

Overcoming atmospheric resistance becomes the dominant consumer of engine power at high speeds.

Analyse tyre contact patch deformation under improper inflation

Under-inflation increases the rolling resistance coefficient and concentrates friction along tyre shoulders.

Lower pneumatic pressure allows sidewall sagging and higher cyclic deformation energy losses as the wheel turns.

Question 674Question →

You are driving along an urban road and intend to turn left into an upcoming side road. In what sequential order should you carry out the following actions, from first to last, in accordance with the Mirrors-Signal-Manoeuvre (MSM) routine and safe signalling practices?

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence begins with checking the interior and left exterior mirrors, followed by activating the left indicator in good time, adjusting vehicle speed and road position for the turn, and finally completing the turn while verifying that the indicator has cancelled.

According to The Highway Code and the standard MSM (Mirrors-Signal-Manoeuvre) routine, drivers must always check interior and exterior mirrors before giving a signal. Signalling must occur in good time before adjusting speed or vehicle position. Once the manoeuvre is completed, confirming that the indicator has cancelled ensures that misleading signals are not given to other road users.

Step-by-Step Solution

Check rear-view and left door mirrors

Situational awareness of following vehicles and vulnerable road users is established before signalling.

The Highway Code requires the Mirrors-Signal-Manoeuvre routine; observations must always be made before taking action.

Apply the left indicator well in advance

A clear, unambiguous intention is communicated to traffic ahead and behind.

Signalling in good time gives other road users sufficient time to react safely before your vehicle changes speed or position.

Adjust speed and position to commence the manoeuvre

The vehicle approaches the junction at a safe speed and on a proper line.

Physical changes in vehicle movement form the manoeuvre phase, occurring after the intention has been clearly signalled.

Complete the turn and confirm signal cancellation

The vehicle enters the new road without displaying a lingering, misleading signal.

Rule 103 of The Highway Code emphasises that signals must not be left on after completing a manoeuvre to prevent confusion.

Question 675Question →

A qualified driver supervising a learner driver from the front passenger seat is legally permitted to hold and use a handheld mobile phone while the vehicle is in motion on a public road.

True

False

Show answer & explanation

Answer: False

Answer

The statement is false. UK law strictly prohibits supervising drivers from holding or using a handheld mobile phone while the vehicle is being driven.

The correct answer is False because Highway Code Rule 149 and UK road traffic legislation strictly state that you must not use a handheld mobile phone, sat-nav, tablet, or any interactive communication device while driving or supervising a learner driver. A supervisor must devote their entire attention to monitoring the road, anticipating hazards, and guiding the novice driver.

Step-by-Step Solution

Identify the legal role and duty of care of an accompanying driver supervising a provisional licence holder.

The supervisor shares legal responsibility for the vehicle's safe progress and must remain fully alert to road hazards and the learner's actions.

Effective supervision requires continuous observation and mental readiness to intervene verbally or physically to prevent incidents.

Evaluate how UK mobile phone regulations (The Road Vehicles (Construction and Use) Regulations and Highway Code Rule 149) apply to supervisors.

The handheld mobile phone ban explicitly applies to anyone supervising a learner driver while the vehicle is in motion.

Interacting with a handheld device causes physical, visual, and cognitive distraction that prevents the supervisor from monitoring the environment.

Determine the accuracy of the statement based on the legal framework.

The statement is false, as supervisors face identical legal penalties, fines, and penalty points for handheld device use.

Holding a phone while supervising is an offence under UK road traffic law.

Question 677Question →

If you are being closely followed by a tailgater, gradually easing off the accelerator to increase your separation distance from the vehicle ahead creates a safer braking buffer for both vehicles.

True

False

Show answer & explanation

Answer: True

Answer

True. Easing off the accelerator to build a larger gap in front gives you more time to react and brake gradually, compensating for the lack of space left by the tailgater behind.

When another driver follows too closely, you lose the safety cushion behind you. The safest defensive response under Highway Code guidelines is to ease off the accelerator and double your forward gap. This ensures you will never have to brake sharply, protecting both your vehicle and the vehicle tailgating you.

Step-by-Step Solution

Assess the hazard created by a tailgating driver behind your vehicle.

Identified that the close-following vehicle has insufficient stopping and thinking distance.

If sudden braking is required, the close vehicle behind is at high risk of causing a rear-end collision.

Determine the correct defensive driving adjustment in relation to the vehicle ahead.

Gently ease off the accelerator to expand the forward gap beyond the standard separation distance.

You cannot control the distance behind, but you can control the safety margin ahead.

Evaluate how an expanded forward buffer manages overall risk.

A larger gap ahead enables earlier hazard anticipation and smooth, progressive deceleration.

Smooth deceleration allows the tailgater behind sufficient time and distance to slow down safely without abrupt impacts.

Answer: Ignore the distraction and keep your concentration focused on the road ahead

Answer

Ignore the distraction and keep your concentration focused on the road ahead

As a driver, your primary responsibility is vehicle control and road safety. External events, scenery, and passenger comments should not distract your attention from scanning the road ahead and anticipating hazards.

Step-by-Step Solution

Identify the external distraction trigger

Recognise that passenger remarks and unusual roadside events (such as a landing hot air balloon) can pull visual and cognitive attention away from driving.

Safe driving requires continuous awareness of potential distraction sources.

Prioritise forward observation and hazard scanning

Maintain a steady course and scanning pattern on the carriageway ahead, resisting the urge to look at external scenery.

Brake firmly to restore your full two-second separation distance immediately.

Gradually ease off the accelerator to steadily re-establish a safe separation distance from the vehicle ahead.

Flash your headlights repeatedly while maintaining your speed to signal the overtaking driver.

Accelerate closer to the vehicle in front to prevent any further vehicles from pulling in.

Show answer & explanation

Answer: Gradually ease off the accelerator to steadily re-establish a safe separation distance from the vehicle ahead.

Answer

Gradually ease off the accelerator to steadily re-establish a safe separation distance from the vehicle ahead.

When another vehicle cuts into your safe following buffer while a tailgater is behind you, braking sharply creates an immediate risk of a rear-end collision. The safest defensive driving technique is to ease off the accelerator smoothly, allowing your vehicle to naturally fall back until the proper two-second separation gap is restored.

Step-by-Step Solution

Assess the forward and rearward hazards.

Identified that the front following distance is compromised by a cut-in vehicle and the rear margin is compromised by a tailgater.

Any sudden action in front could trigger a collision from behind.

Select a smooth method of speed adjustment.

Choose gradual deceleration without harsh pedal braking.

Lifting off the accelerator reduces speed progressively, preventing sudden shock to the close follower behind.

Rebuild the safety margin.

Restore the minimum two-second gap (or four seconds if conditions deteriorate).

A proper gap gives you adequate time to see hazards and brake gently if the vehicle ahead stops.

At 30 mph on ice, the standard 14m braking distance increases tenfold to 140m, while the 9m thinking distance stays the same, creating a total stopping distance of 149m. Subtracting the dry distance (96m) from the icy distance (149m) results in a difference of 53 metres.

Step-by-Step Solution

Calculate the total stopping distance at 70 mph on a dry road.

Thinking distance = 21 metres, Braking distance = 75 metres. Total = 96 metres.

To establish the baseline stopping distance for the first scenario using standard Highway Code figures.

Calculate the total stopping distance at 30 mph on an icy road.

Thinking distance = 9 metres. Braking distance (14 metres) x 10 = 140 metres. Total = 149 metres.

Ice increases braking distance by a factor of ten, but human reaction time (thinking distance) remains unaffected by the road surface.

Determine the difference between the two total stopping distances.

149 metres (icy) - 96 metres (dry) = 53 metres.

To answer the specific question asked in the stem regarding the exact difference.
