You are completing a long journey on a dual carriageway and begin to feel sleepy. In what order should you carry out the following actions to safely manage this fatigue according to official road safety guidelines?

Drag items to arrange them in the correct order

Show answer & explanation

Answer

Exit safely at a service area → Drink two cups of caffeinated coffee → Take a short 15-minute nap → Check alertness before resuming driving
According to official DVSA guidance and Highway Code Rule 91, the only effective countermeasure for driver fatigue is proper rest. When tiredness occurs, drivers must safely exit the road at an approved rest facility, consume a caffeinated beverage, take a short nap of around 15 minutes to allow the caffeine to enter their system, and ensure they feel completely refreshed before resuming their journey.

Step-by-Step Solution

1
Leave the roadway at a safe, designated parking area or service facility.
The vehicle is secured away from moving traffic in an authorised stopping place.
Stopping on the roadway or hard shoulder to rest is illegal and hazardous.
2
Consume a high-caffeine drink such as two cups of coffee.
Caffeine begins entering the system to boost alertness.
Caffeine takes approximately 15 to 20 minutes to take effect in the body.
3
Rest or sleep for approximately 15 minutes.
Fatigue is reduced without entering deep sleep, coinciding with caffeine activation.
A brief nap helps combat sleepiness while giving the caffeine sufficient time to work.
4
Assess your condition to ensure full alertness before driving.
Full alertness and safe driving capability are confirmed.
A driver must never resume driving until they are completely fit and alert.

Question 62Question →

When driving on rural roads with blind bends and hidden junctions, actively scanning over low hedges and walls for vehicle rooflines or reflections allows you to anticipate oncoming traffic earlier.

Show answer & explanation

Answer: True

Answer

True, because scanning across landscape features such as hedges and walls allows early detection of approaching vehicles before they reach blind spots or bends.
Proactive drivers continuously scan the broader landscape, including looking over low walls and hedges, to identify early clues such as vehicle rooflines or reflections before negotiating concealed junctions or bends.

Step-by-Step Solution

1
Identify the visual scanning technique described in the scenario.
Looking over and through roadside obstacles such as hedges and walls to gather early information about other road users beyond the direct line of the road.
Effective anticipation requires looking beyond the immediate tarmac to gather early environmental indicators.
2
Evaluate how this technique affects hazard anticipation on rural roads.
Spotting rooflines, headlights, or glints of sunlight gives advanced warning of approaching traffic before blind bends or hidden junctions.
Early warning allows the driver to reduce speed, adjust road position, and prepare for potential conflicts smoothly.
3
Determine the truth value of the statement.
The statement accurately reflects proactive hazard anticipation and continuous scanning principles established in UK driving standards.
Continuous scanning incorporates the wider driving environment to foresee hazards before they materialize in the immediate path.

Question 63Question →

You are driving on a busy urban road approaching a series of traffic lights and pedestrian crossings. Why should you continuously scan well ahead rather than focusing only on the vehicle directly in front of you?

Show answer & explanation

Answer: To identify developing hazards early and allow smooth, gradual adjustments to your speed

Answer

Scanning well ahead allows you to identify developing hazards early so you can adjust your speed smoothly and safely.
Continuously scanning well ahead allows a driver to anticipate changes in traffic flow, such as queues forming or traffic lights changing, providing sufficient time to adjust speed smoothly and safely without harsh braking.

Step-by-Step Solution

1
Assess the visual demands of driving in a busy urban environment
Recognise that hazards develop not just immediately ahead, but across junctions, pedestrian crossings, and traffic queues further down the road.
Effective scanning requires monitoring the far distance, middle ground, and mirrors continuously.
2
Evaluate the primary benefit of early hazard detection
Early awareness allows time to ease off the accelerator and brake progressively rather than reacting abruptly.
Anticipation prevents harsh braking, protects following road users, and maintains vehicle control.

Question 64Question →

You are reversing into a side road on the left to turn your vehicle around. As you prepare to apply steering lock to guide the rear of your car into the junction, the front of your car will swing out into the main road. What observation should you make immediately before turning the steering wheel?

Show answer & explanation

Answer: Check all around the vehicle, paying particular attention to traffic and road users to the front and right-hand side.

Answer

Check all around the vehicle, paying particular attention to traffic and road users to the front and right-hand side.
When reversing around a corner or into a side road to the left, turning the steering wheel causes the front of the vehicle to swing out across the main carriageway. A driver must perform effective all-round observations, giving particular attention to the front and right (offside), to ensure no oncoming vehicles, cyclists, or pedestrians will be endangered by the protruding front end.

Step-by-Step Solution

1
Identify the vehicle trajectory and physical dynamics during the manoeuvre.
Recognise that applying left steering lock while reversing forces the front offside of the car to swing out into the main carriageway.
Vehicle steering geometry causes the front end to describe a wider outward arc than the rear wheels.
2
Determine the critical hazard areas created by the front swing.
Potential conflict zones include oncoming vehicles, overtaking traffic, and vulnerable road users approaching from the front or right.
Drivers who only look backwards or in mirrors will miss vehicles approaching the protruding front bumper.
3
Execute the comprehensive pre-manoeuvre observation routine.
Perform a complete 360-degree all-round check, checking blind spots and ensuring clear passage to the front and right before steering.
Ensures the manoeuvre does not endanger or impede other road users.

Question 65Question →

To anticipate potential hazards effectively and maintain situational awareness, in what sequence should you systematically scan your driving environment, starting from the furthest visual range to your immediate surroundings?

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct systematic scanning sequence begins by scanning the far distance, followed by sweeping the middle distance, checking the immediate foreground, and concluding with a check of the interior and exterior mirrors.
A safe driver continuously scans in a structured cycle: starting with the far distance to plan well ahead, scanning the middle distance to identify emerging hazards, monitoring the immediate foreground for vehicle positioning and road conditions, and regularly checking mirrors to maintain 360-degree awareness of surrounding traffic.

Step-by-Step Solution

1
Identify the start of the scanning routine at the maximum visual horizon.
Early awareness of the overall road layout and distant conditions.
Looking far ahead provides maximum reaction time to plan ahead.
2
Move gaze to the middle distance.
Detection of developing hazards and potential conflicts from side roads.
Intermediate scanning bridges distant planning with immediate action.
3
Assess the immediate foreground.
Accurate vehicle positioning and awareness of road surface quality.
Near-range checks ensure stable road holding and safe lane alignment.
4
Check interior and exterior mirrors.
Clear picture of trailing traffic and vehicles in adjacent lanes.
Completing the cycle with mirrors prevents being surprised from behind before taking action.

Question 66Question →

When following traffic on approach to a busy multi-lane junction, what is the main benefit of continuously scanning the wider road ahead rather than focusing solely on the vehicle in front?

Show answer & explanation

Answer: It allows you to spot early clues of developing hazards and adjust your speed smoothly.

Answer

It allows you to spot early clues of developing hazards and adjust your speed smoothly.
Continuously scanning the road ahead—including the far distance, middle ground, and mirrors—gives you early notice of developing hazards. This proactive observation allows you to adjust your speed, gear, and road position smoothly rather than braking suddenly at the last second.

Step-by-Step Solution

1
Analyze the driving environment on approach to the junction
Identify potential sources of conflict including changing traffic signals, queuing vehicles, turning traffic, and pedestrians.
Approaching a complex multi-lane junction involves multiple interacting road users and rapidly changing situations.
2
Apply a continuous visual scanning technique across near, intermediate, and far zones
Gain early awareness of brake lights, indicator signals, and lane obstructions well ahead of your immediate position.
Scanning wide and far ahead prevents tunnel vision and gives you the necessary time to plan and react calmly.
3
Select the response that correctly reflects effective hazard anticipation
Recognize that early hazard detection enables proactive, smooth speed and positional adjustments.
Anticipation minimizes harsh braking and reduces the risk of collisions.

Key Concept

Continuous scanning and anticipation allow drivers to detect developing hazards early, providing time to plan and respond smoothly rather than reacting abruptly.

Question 67Question →

You are parked on the right-hand side of a one-way street and intend to move off into the flow of traffic. Which TWO observation checks must you carry out before you move away?

Select all that apply

Show answer & explanation

Answer: Check your interior mirror and left exterior door mirror; Look over your left shoulder to check the blind spot towards the carriageway

Answer

The driver must check the interior mirror and left exterior door mirror, and look over their left shoulder to check the blind spot beside the active traffic lane before moving off.
When parked on the right-hand side of a one-way street, traffic approaches and passes on your left. Before moving away into the flow of traffic, you must check your interior mirror and left door mirror to observe approaching vehicles, and perform a check over your left shoulder to ensure no vulnerable road users or vehicles are in the left-side blind spot.

Step-by-Step Solution

1
Assess the vehicle position and traffic flow direction
Identify that the vehicle is parked on the right side of a one-way street, meaning moving traffic passes on the left.
Manoeuvring safely requires adjusting observation routines to the specific road layout and side of the carriageway.
2
Check rear-view and left exterior door mirrors
Gain initial awareness of following traffic approaching along the lane to your left.
Mirrors provide early awareness of vehicles approaching from behind in the live lane.
3
Conduct a physical left shoulder check into the blind spot
Ensure no hidden road users, such as cyclists or overtaking vehicles, are alongside your vehicle.
Door and interior mirrors have blind spots that can only be cleared with direct shoulder observation before executing a manoeuvre.

Key Concept

Pre-manoeuvre observation on the right side of a one-way street requires mirror checks and shoulder blind spot checks on the left side where traffic flows.

Question 68Question →

When driving along a street with parked vehicles, observing the angle of their front wheels and watching for exhaust emissions are effective visual scanning techniques to anticipate a vehicle pulling out.

Show answer & explanation

Answer: True

Answer

True
Continuous scanning involves looking for early physical cues—such as turned front tyres, exhaust emissions, illuminated brake lights, and driver presence—so that potential hazards can be anticipated well before a vehicle enters your path.

Step-by-Step Solution

1
Analyze the visual scanning cues associated with stationary vehicles preparing to enter traffic.
Front wheels turned outwards toward the carriageway and active exhaust emissions indicate that the engine is running and the driver may be preparing to pull away.
Effective anticipation requires recognizing preliminary physical signs of hazard development before movement occurs.
2
Evaluate how identifying these cues impacts driver response and safety margins.
Noticing these indicators early allows the driver to adjust road position, check mirrors, and moderate speed smoothly without abrupt braking.
Proactive observation prevents emergency reactions and reduces the risk of side-swipe or rear-end collisions.

Question 69Question →

You are driving along a two-way suburban road and need to pull out to pass a large delivery lorry parked on your side of the carriageway. Before you signal and steer across the centre line, why is it essential to check your right-hand blind spot in addition to your mirrors?

Show answer & explanation

Answer: To detect any overtaking vehicle or motorcyclist that cannot be seen in your mirrors

Answer

To detect any overtaking vehicle or motorcyclist that cannot be seen in your mirrors
Before signalling and moving out to pass an obstruction, drivers must check their mirrors and perform an offside blind-spot shoulder check. This confirms that no vehicle, motorcyclist, or cyclist has committed to overtaking from behind in the area not covered by mirrors.

Step-by-Step Solution

1
Assess the forward road and the obstruction
Identify that passing the stationary lorry requires crossing into the oncoming lane.
You must first ensure there is adequate road space and no oncoming traffic before planning to pull out.
2
Execute the Mirrors-Signal-Manoeuvre (MSM) routine
Check interior and right door mirrors to evaluate traffic approaching from behind.
Mirrors provide early awareness of following road users.
3
Carry out an over-the-shoulder right blind-spot check before signalling or steering
Confirm that no faster vehicle, motorcyclist, or cyclist has already begun overtaking in the unreflected blind area.
Mirrors have blind spots; moving out across the centre line without checking over your shoulder risks a collision with an overtaking road user.

Key Concept

Pre-manoeuvre observation requires checking both mirrors and the blind spot over the shoulder before altering course or overtaking an obstruction.

Question 70Question →

Approaching a series of mini-roundabouts on a busy suburban route, why should you continuously scan the entire road environment rather than looking only at the vehicle immediately ahead?

Show answer & explanation

Answer: To identify developing hazards early and adjust your speed smoothly before situations become critical

Answer

To identify developing hazards early and adjust your speed smoothly before situations become critical
Maintaining a continuous scanning routine across the wider road scene enables the driver to identify early clues, such as traffic building up at an upcoming roundabout or vehicles waiting at side turnings. This early anticipation gives sufficient time to ease off the accelerator and brake smoothly, maintaining total control.

Step-by-Step Solution

1
Analyze the purpose of scanning the wider driving environment
Recognize that road situations change continuously with potential hazards emerging from side turnings, pedestrian crossings, and upcoming junctions
Anticipation requires looking beyond the vehicle directly in front to build an accurate mental model of the entire traffic scene.
2
Evaluate the effect of early hazard detection on driving safety and control
Early awareness allows gradual deceleration, appropriate gear selection, and smooth vehicle control rather than emergency stops
Proactive planning increases safety margins and reduces collision risk for all road users.

Key Concept

Continuous visual scanning across near, middle, and far distances enables early hazard anticipation and smooth vehicle control.

Question 71Question →

Correctly adjusting your interior and exterior mirrors completely eliminates all blind spots around your vehicle.

Show answer & explanation

Answer: False

Answer

False
Mirrors cannot show every angle around a vehicle. Areas outside your field of vision in the mirrors are called blind spots, and they can only be checked by looking directly over your shoulder.

Step-by-Step Solution

1
Assess the coverage area of interior and exterior mirrors
Mirrors provide rearward and slight side visibility, but their fields of view do not overlap completely around the vehicle.
Optical reflection angles and vehicle bodywork naturally limit what mirrors can show.
2
Evaluate whether any mirror configuration can eliminate blind spots
Areas over the driver's shoulders and alongside the rear quarter panels remain invisible in mirrors, confirming blind spots always exist.
A physical glance over the shoulder is mandatory to cover these unseen areas before moving off or changing lanes.

Question 72Question →

You are driving in multi-lane traffic and intend to change lanes. You have checked your interior and exterior mirrors. Why must you also take a quick sideways glance over your shoulder before moving?

Show answer & explanation

Answer: To check for other vehicles or vulnerable road users hidden in areas your mirrors cannot show

Answer

To check for other vehicles or vulnerable road users hidden in areas your mirrors cannot show
Even properly adjusted interior and exterior mirrors cannot cover all angles around a vehicle. Blind spots exist alongside the vehicle's rear quarters and behind pillars. Taking a brief sideways glance over your shoulder allows you to check these hidden areas for other vehicles, motorcyclists, or cyclists before steering into another lane.

Step-by-Step Solution

1
Assess the visual coverage of interior and exterior mirrors
Recognise that mirrors have limited angles of view and leave unmonitored blind spot zones alongside the vehicle's rear quarters.
Mirrors cannot reflect every angle around the car, especially areas obscured by body pillars or alongside the rear flanks.
2
Identify the purpose of taking a sideways glance (shoulder check)
Direct line-of-sight visual check confirms whether any road user, such as a motorcycle or car, is alongside in the blind spot.
A physical glance into the blind spot prevents side-swiping or cutting across another road user who is hidden from mirror view.

Question 73Question →

You intend to change lanes in flowing traffic. What is the main reason for looking over your shoulder to check your blind spot?

Show answer & explanation

Answer: To check for any vehicles or vulnerable road users hidden from mirror view

Answer

To check for any vehicles or vulnerable road users hidden from mirror view
Vehicle blind spots are areas around the vehicle that cannot be seen directly in either the interior rear-view mirror or the exterior door mirrors. Performing a physical check over the appropriate shoulder before changing lanes ensures that any road users, especially vulnerable ones like motorcyclists or cyclists travelling alongside, are spotted before beginning the manoeuvre.

Step-by-Step Solution

1
Identify the optical limitations of vehicle mirrors
Recognise that interior and exterior door mirrors cannot provide a 360-degree view around the vehicle.
Areas to the side and slightly behind the driver fall outside mirror coverage zones.
2
Determine the safety function of a physical shoulder check
Understand that looking over the shoulder reveals any road users travelling alongside in these uncovered areas.
Motorcyclists, cyclists, and small cars can easily be completely concealed within vehicle blind spots.

Key Concept

Understanding that vehicle mirrors do not eliminate all blind spots and direct observation is required before changing lanes
Question 74Question →

You are driving in the left-hand lane of a three-lane motorway and plan to move out into the middle lane to overtake a slower lorry. You have checked your rear-view and right-side exterior mirrors and applied your right indicator. Why is it vital to carry out a final check of your right-hand blind spot before changing lanes?

Show answer & explanation

Answer: To check for a vehicle in the right-hand lane that may be moving into the middle lane at the same time

Answer

To check for a vehicle in the right-hand lane that may be moving into the middle lane at the same time
When travelling in the left-hand lane of a three-lane motorway, another vehicle travelling in the right-hand lane may decide to move into the middle lane at the exact same moment. Because standard exterior mirrors do not show vehicles positioned slightly behind and two lanes across, a prompt glance over the right shoulder into the vehicle blind spot is essential to prevent two vehicles colliding in the middle lane.

Step-by-Step Solution

1
Assess the multi-lane motorway environment and potential traffic movements across all three lanes.
Identified that traffic in the right-hand lane may also intend to change into the middle lane simultaneously.
On a three-lane carriageway, the middle lane can be targeted by vehicles from both the left and right lanes at the same moment.
2
Analyze mirror coverage limitations versus physical observation.
Exterior side mirrors leave a blind spot area over the right shoulder where a vehicle transitioning from lane 3 to lane 2 cannot be seen.
Mirrors only cover specific angles behind and alongside; areas level with or slightly behind the rear pillars require a direct head check.
3
Execute the shoulder blind-spot check before crossing lane boundaries.
Ensures the target lane space is entirely clear and no other driver is moving into the exact same space.
Prevents sideswipe collisions caused by simultaneous manoeuvres into the same lane space.

Key Concept

Question 75Question →

You are approaching a junction where your road joins a major carriageway at an acute angle (a sharp Y-junction). Due to the alignment of your vehicle at the give-way line, traffic approaching on the main road falls completely outside the coverage of your exterior mirrors. What observation action must you take before deciding to emerge?

Show answer & explanation

Answer: Turn your head to look directly over your shoulder through the side and rear-quarter windows

Answer

Turn your head to look directly over your shoulder through the side and rear-quarter windows to check approaching traffic directly.
When joining a carriageway at an acute angle, your car is positioned so that traffic approaching on the main road travels from behind your rear side. Standard exterior and interior mirrors cannot display this area. The only safe way to verify that the road is clear is to turn your head and look directly over your shoulder through the side and rear-quarter windows before crossing the give-way line.

Step-by-Step Solution

1
Assess vehicle alignment and mirror limitations at the junction.
Recognise that an acute-angled junction positions oncoming priority traffic behind the car's rear quarter, outside standard mirror field of view.
Mirrors reflect directly backwards relative to the vehicle body, creating massive blind zones when joined at sharp angles.
2
Perform physical direct observation over the appropriate shoulder before moving.
Obtain an unobstructed, direct line of sight through side and rear-quarter windows to evaluate the speed and distance of approaching traffic.
A physical shoulder check is the only reliable method to eliminate blind spots caused by acute road geometry.
3
Emerge only when a safe, clear gap in priority traffic is positively confirmed.
Join the carriageway smoothly without causing approaching road users to brake or swerve.
The Highway Code requires drivers to ensure the manoeuvre can be made safely before crossing the give-way line.

Key Concept

Pre-manoeuvre observation at acute-angled junctions requires direct over-the-shoulder checks because exterior mirrors cannot capture traffic approaching from sharp angles.

Question 76Question →

During a reverse parallel parking manoeuvre on a congested urban road, a driver's view of the nearside pavement is severely restricted by a high-sided van parked immediately in front of the target space. With an impatient queue of traffic building up behind, which observation strategy is absolutely vital immediately before the vehicle begins to move backwards?

Show answer & explanation

Answer: Conducting a thorough 360-degree physical sweep to confirm the offside is clear of overtaking vehicles, followed by a sustained check over the left shoulder to detect pedestrians emerging from the van's blind spot.

Answer

The driver must conduct a thorough 360-degree physical sweep, prioritizing checks over the left shoulder for pedestrians obscured by the van and checking the offside for impatient drivers attempting to overtake.
A comprehensive physical 360-degree check is mandatory before reversing, especially in congested areas with restricted visibility. The driver must physically turn to check the offside blind spot for queuing drivers attempting an illegal or dangerous overtake, and critically, check over the left shoulder because the high-sided van completely obscures the nearside pavement where pedestrians may be waiting to cross.

Step-by-Step Solution

1
Analyze the environmental restrictions.
Identify that the parked high-sided van creates a significant nearside blind spot that completely hides potential pedestrians on the pavement.
Parked commercial vehicles act as static hazards that frequently mask vulnerable road users from a driver's normal line of sight.
2
Evaluate the dynamic hazards.
Recognize that the impatient queuing traffic presents a high risk of vehicles abruptly attempting to overtake the parking manoeuvre on the offside.
Congested traffic increases driver frustration, which often leads to unpredictable and dangerous overtaking decisions.
3
Determine the correct observation protocol.
Conclude that relying on mirrors or focusing on a single hazard is insufficient; a full physical 360-degree check is mandatory before moving.
Mirrors alone cannot cover the extensive blind spots created by the vehicle's pillars and the adjacent parked van, making direct over-the-shoulder checks the only safe method.

Key Concept

Comprehensive physical observation checks in high-risk, restricted-view environments.

You are preparing for a journey accompanied by passengers and need to use a satellite navigation system (sat-nav). Which TWO actions should you take to minimise in-vehicle distractions whilst driving?

Select all that apply

Show answer & explanation

Answer: Programme and check your sat-nav destination route prior to setting off; Ask passengers to keep conversations calm and avoid behaviour that demands your direct attention

Answer

Programme your sat-nav destination prior to setting off, and ask passengers to maintain calm behaviour that does not draw your attention from the road.
Programming your sat-nav destination before setting off ensures you do not take your hands off the controls or your eyes off the road. Establishing passenger expectations keeps the vehicle cabin calm, allowing the driver to concentrate fully on driving safely.

Step-by-Step Solution

1
Identify proactive measures required before moving off
Entering the route into the sat-nav before driving eliminates the hazard of manipulating screens while on the road.
Highway Code Rule 150 requires drivers to maintain full control of their vehicle at all times, making pre-trip device configuration essential.
2
Manage passenger dynamics inside the cabin
Setting clear expectations with passengers minimises unexpected loud noises, arguments, or demands for attention.
Drivers are responsible for ensuring in-cabin activity does not impair their ability to anticipate and react to external hazards.

Question 78Question →

When following a large goods vehicle on the approach to a complex junction, dropping back to increase your separation distance improves your hazard anticipation by expanding your forward field of view to spot overhead direction signs and changing traffic conditions earlier.

Show answer & explanation

Answer: True

Answer

True. Dropping back from a large vehicle widens your field of vision, allowing you to scan further ahead, read overhead signage, and anticipate traffic changes well in advance.
The statement is true because dropping back increases the angular field of view around a large vehicle, allowing a driver to scan ahead for overhead signage, lane indications, and junction hazards with sufficient time to plan actions safely.

Step-by-Step Solution

1
Identify the visual limitation caused by following a large goods vehicle closely.
Recognise that a high-sided vehicle severely restricts the forward visual horizon and blocks road layout cues.
Effective anticipation depends on receiving visual information early enough to plan and adapt speed and road position.
2
Evaluate the visual effect of increasing following distance on the approach to a junction.
Determine that dropping back opens up the visual angles around and above the large vehicle.
A broader visual field permits continuous scanning of overhead gantries, lane markings, and junction layouts.
3
Conclude whether dropping back facilitates proactive hazard anticipation.
Confirm that expanding the forward sightline directly supports early hazard perception and smooth decision-making.
Proactive drivers use space to maintain visual scanning rather than reacting late to the brake lights of leading vehicles.

Question 79Question →

A vehicle fitted with an electronic blind-spot monitoring system removes the need for the driver to carry out direct visual shoulder checks before changing lanes.

Show answer & explanation

Answer: False

Answer

False
Electronic blind-spot monitoring systems are designed to assist driver awareness, not replace essential visual checks. Because sensors can fail to detect rapidly approaching vehicles or narrow road users such as pedal cyclists and motorcyclists, drivers must always perform a direct physical shoulder check before manoeuvring.

Step-by-Step Solution

1
Analyze the operational limitations of electronic blind-spot monitoring systems.
Driver assistance sensors can be obstructed by dirt or severe weather and may have restricted detection zones that fail to register narrow or rapidly approaching road users.
Understanding sensor limitations prevents dangerous over-reliance on automated driving aids.
2
Apply standard observation procedures for changing lanes.
A physical glance over the appropriate shoulder into the blind spot remains mandatory before steering across lane boundaries.
Direct visual confirmation ensures that the blind area beside and behind the vehicle is genuinely clear.

Question 80Question →

You are driving a standard car in slow-moving urban traffic and intend to turn left at an upcoming junction. A cyclist is riding in a designated cycle lane on your left. Directly ahead of you, a Large Goods Vehicle (LGV) is also signaling left for the same junction, but the driver begins to steer out towards the right-hand lane before the turn. Considering the blind spots of all vehicles involved, what is the safest course of action?

Show answer & explanation

Answer: Hold your position well behind the LGV until it completes its turn, and perform a physical check over your left shoulder to ensure the cyclist is clear before you proceed.

Answer

Hold your position well behind the LGV until it completes its turn, and perform a physical check over your left shoulder to ensure the cyclist is clear before you proceed.
Safe navigation in this scenario requires managing two distinct blind spot hazards. First, you must stay out of the LGV's extensive near-side blind spot by holding back and allowing it to complete its wide turning arc. Second, you must actively clear your own vehicle's blind spot by performing a physical left shoulder check to ensure you do not turn across the path of the cyclist.

Step-by-Step Solution

1
Identify the LGV's maneuver and road position.
Recognize that the LGV is swinging right to create necessary space for a sharp left turn.
LGVs have long wheelbases and extensive blind spots; understanding their turning arc prevents you from entering high-risk crush zones on their near side.
2
Adjust your vehicle's position and speed.
Hold back and maintain a safe distance behind the LGV.
Staying well back keeps you visible in the LGV driver's mirrors and ensures you are not trapped as the rear of the trailer sweeps across the junction.
3
Monitor the vulnerable road user.
Track the cyclist's position in the dedicated near-side lane.
Cyclists often travel straight ahead at junctions and can easily disappear into your vehicle's near-side blind spot.
4
Perform final safety checks before executing your turn.
Look in the interior mirror, left exterior mirror, and physically over your left shoulder.
A physical shoulder check is the only reliable method to confirm your near-side blind spot is completely clear of cyclists before steering left.
