Match each driving scenario involving agricultural vehicles with the correct Highway Code regulation or required driver action.

Click a left item, then click its matching right item

Show answer & explanation

Answer

The correct matches are: The 15 mph tractor on a solid white line means you must not cross to overtake. The tractor indicating right while positioned left means you must stay back to allow sweep space. The 25 mph vehicle on a dual carriageway requires an amber flashing beacon. The mud near the gateway requires extending following distance and avoiding harsh braking.

Each scenario represents a specific hazard or regulation related to agricultural vehicles. You cannot cross a solid white line to overtake a tractor at 15 mph because exceptions only apply to bicycles, horses, and road maintenance vehicles travelling at 10 mph or less. Tractors often swing in the opposite direction of their turn to allow trailers to clear the corner, so undertaking is highly dangerous. Amber beacons are legally required for slow vehicles on dual carriageways to prevent rear-end collisions. Finally, mud significantly reduces traction, requiring smooth driving inputs.

Step-by-Step Solution

Analyze the solid white line scenario.

Identify that the tractor exceeds 10 mph and is not a road maintenance vehicle, bicycle, or horse.

This determines that overtaking by crossing the solid line is strictly illegal under Highway Code Rule 129.

Evaluate the positioning of the indicating tractor.

Recognize that a vehicle positioned left but indicating right is preparing for a wide turning sweep.

Understanding the physics of a towing vehicle prevents the dangerous mistake of undertaking into the blind spot.

Assess the dual carriageway scenario.

Recall that slow-moving vehicles (<25 mph) require high-visibility warnings on fast roads.

This matches the legal requirement for a flashing amber beacon to prevent high-speed rear-end collisions.

Identify the hazard presented by the mud.

Conclude that the coefficient of friction is compromised.

This necessitates smoother driving inputs and longer separation distances to prevent skidding.

Key Concept

Comprehensive hazard management and legal compliance when sharing the road with agricultural vehicles.

Question 1162Question →

As you drive behind a heavy goods vehicle, why is it vital to ensure you can clearly see both of its exterior side mirrors?

To prompt the lorry driver to flash their headlights to signal you through

To ensure that the lorry driver is able to see your vehicle in their mirrors

To position yourself to pass the lorry on the inside when traffic slows down

To eliminate the need for your own blind spot checks before changing lanes

Show answer & explanation

Answer: To ensure that the lorry driver is able to see your vehicle in their mirrors

Answer

To ensure that the lorry driver is able to see your vehicle in their mirrors

Large goods vehicles have substantial blind spots directly behind them. If you cannot see the driver's side mirrors, the lorry driver cannot see your vehicle. Keeping far enough back so that both mirrors are visible ensures the driver is aware of you and significantly improves your view of the road ahead.

Step-by-Step Solution

Assess your position relative to the commercial vehicle ahead

Identify whether the lorry's exterior side mirrors are visible from your driving position

Large goods vehicles have substantial blind spots directly behind their trailers where following traffic is hidden from view

Maintain a generous following distance that keeps both cab mirrors in clear view

The lorry driver can monitor your position in their mirrors, and your forward visibility is significantly improved

If you cannot see the driver's side mirrors, the driver cannot see your vehicle, creating serious danger if the vehicle slows down or changes position

Question 1163Question →

You are driving on a wet road and approaching a sharp bend. How should you adjust your driving to reduce the risk of skidding?

Brake firmly while steering around the bend

Depress the clutch pedal and coast through the bend

Reduce your speed smoothly in a straight line before entering the bend

Accelerate briskly into the bend to increase tyre traction

Show answer & explanation

Answer: Reduce your speed smoothly in a straight line before entering the bend

Answer

Reduce your speed smoothly in a straight line before entering the bend

Slowing down in good time before turning ensures that tyre grip is not compromised by braking forces while cornering. On wet roads, demanding both sharp steering and heavy braking at the same time is one of the most common causes of skidding.

Step-by-Step Solution

Assess the upcoming road hazard and surface conditions on approach

Identify that the combination of a sharp bend and wet surface significantly lowers the threshold for losing tyre grip

Tyres have a finite amount of adhesion shared between steering, braking, and accelerating

Separate braking from steering by gently reducing speed before the turn begins

The vehicle enters the corner at a safe, stable speed without demanding simultaneous heavy braking and steering inputs

Completing deceleration in a straight line reserves full tyre grip for directional control through the curve

Key Concept

Separating braking and steering to manage tyre grip and prevent skids on slippery bends

Question 1164Question →

When scanning the road ahead in a built-up area, observing a driver seated inside a stationary parked vehicle checking their side mirror or turning their head is an early visual cue to anticipate that the vehicle may pull out or an occupant may open a door into the carriageway.

True

False

Show answer & explanation

Answer: True

Answer

The statement is True.

Hazard perception relies on anticipating developing risks by spotting early behavioral and mechanical clues. Noticing an occupant checking mirrors or turning their head indicates an imminent manoeuvre, requiring the driver to respond defensively by slowing down and monitoring space.

Step-by-Step Solution

Scan the roadside environment actively for early indicators of movement inside or around stationary vehicles.

Identify occupants seated in parked cars making pre-manoeuvre observations such as checking mirrors or turning their heads.

Early detection of potential hazard precursors allows drivers to prepare mentally and physically before a hazard becomes active.

Evaluate the risk that the parked vehicle will pull away from the kerb or that an occupant will open a door into the road.

Recognise the situation as a developing hazard rather than a static element.

Anticipating the actions of others prevents late, reactive braking and sudden swerving.

Adjust your driving approach by checking your rear-view mirrors, easing off the accelerator, and ensuring adequate clearance.

Establish a safe safety margin and speed appropriate for the developing hazard.

Proactive speed and position adjustments ensure you can stop smoothly if an unexpected door opens or a vehicle pulls out.

Question 1165Question →

A large goods vehicle (LGV) ahead of you has stopped and is preparing to reverse into a narrow side entrance. In which order should you complete the following actions to deal with this situation safely?

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is: recognise the hazard from the vehicle's position and reversing lights, stop your vehicle well back from the entrance to stay visible in the driver's mirrors, wait patiently while the lorry completes its turning and reversing manoeuvre, and check that the road ahead is completely clear before resuming your journey.

When an LGV prepares to reverse into a narrow entrance, it requires extra road width and time. Drivers must first identify the manoeuvre, stop well back so their car remains visible in the lorry's side mirrors, wait patiently until the vehicle has fully cleared the carriageway, and verify the path is clear before proceeding.

Step-by-Step Solution

Identify the reversing lights and vehicle positioning as an active manoeuvre hazard.

You anticipate that the vehicle will occupy the road width while reversing.

Early awareness gives you time to react calmly without braking sharply.

Bring your vehicle to a complete stop well before the entrance.

Your vehicle remains visible in the lorry driver's side mirrors and stays outside the vehicle's swing path.

Large goods vehicles have substantial blind spots directly behind them and need wide sweeping arcs to turn.

Hold your position and allow the driver time to complete the manoeuvre.

The lorry enters the side road without conflict or pressure.

Attempting to squeeze past or rushing the driver creates a serious collision hazard.

Perform a complete observation check of the carriageway before moving off.

You proceed safely into an open, hazard-free road.

Verifying the path is clear prevents collisions with oncoming traffic or pedestrians.

Question 1166Question →

While traversing a low-lying section of carriageway covered in standing water, your vehicle begins to float on a layer of water, causing the steering to suddenly feel light and unresponsive. Arrange the following driver actions in the correct chronological order to safely manage the aquaplaning event and re-establish safe driving conditions.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence begins with holding the steering wheel firmly straight, followed by smoothly easing off the throttle, waiting for steering resistance to return as tyres cut through the water, and finally expanding the following distance to at least four seconds.

When a vehicle aquaplanes, water builds up in front of the tyres faster than the tread grooves can disperse it, causing the tyre to ride on a water film with near-zero friction. The driver must first maintain a neutral, straight steering direction to avoid entering a skid when grip returns. Next, smoothly releasing the throttle permits natural deceleration without inducing brake lock-up. Once steering weight returns—confirming tyre-to-road contact—the driver can resume normal control and expand their following distance to at least four seconds to manage ongoing wet road hazards.

Step-by-Step Solution

Maintain a firm, neutral grip on the steering wheel directed straight along your lane path.

Prevents the front tyres from entering a sideways angle while floating on the water film.

If the front tyres are turned while aquaplaning, the car will violently pivot and enter an uncontrollable skid the instant contact is regained.

Gently remove pressure from the accelerator pedal without touching the footbrake.

Allows vehicle speed to decline gradually via aerodynamic and water resistance.

Harsh braking on zero-friction water layers locks the wheels or destabilises the vehicle before grip returns.

Monitor tactile steering feedback until normal resistance and tyre-to-tarmac friction are re-established.

The water wedge beneath the tyre footprint is displaced by the tread grooves, restoring steering and braking authority.

Direct control actions must only be resumed once the tyre rubber has physical contact with the tarmac.

Increase the separation gap to the vehicle in front to a minimum of four seconds.

Accommodates the doubled overall stopping distance required on wet road surfaces.

Highway Code rules mandate doubling the standard two-second dry weather rule to a four-second gap on wet surfaces.

Question 1167Question →

You are driving a car towing a trailer along a smart motorway. An overhead electronic gantry displays the number 70 inside a red circle above each open lane. Under these conditions, what is the maximum legal speed at which you are permitted to drive?

50 mph

60 mph

70 mph

80 mph

Show answer & explanation

Answer: 60 mph

Answer

60 mph

The correct answer is 60 mph. Under the UK Highway Code, cars towing a trailer or caravan are subject to a statutory maximum speed limit of 60 mph on both dual carriageways and motorways. Even when an overhead gantry displays a mandatory 70 mph speed limit inside a red circle, variable speed limit signs cannot raise or override lower statutory limits set for specific vehicle types.

Step-by-Step Solution

Determine the statutory speed limit for the specific vehicle category

Under the UK Highway Code, a car towing a trailer or caravan is restricted to a maximum speed of 60 mph on dual carriageways and motorways.

Vehicle class restrictions apply statutory maximum speed ceilings based on vehicle handling, weight, and braking dynamics.

Interpret the overhead variable speed limit gantry display

The number 70 within a red ring indicates a mandatory maximum speed limit of 70 mph for general motorway traffic.

Signs enclosed within a red ring convey mandatory legal orders and prohibitions.

Apply the rule governing the interaction between general speed limits and vehicle-specific caps

The vehicle must not exceed 60 mph.

An illuminated gantry showing a higher general speed limit (such as 70 mph) cannot raise or override lower statutory vehicle-specific limits.

Question 1168Question →

You are driving along an urban road in wet conditions where tram lines are set flush into the tarmac. What should you do when you need to drive across the metal tram rails?

Brake firmly whilst driving parallel along the top of the rails to test tyre grip

Cross the rails as close to a right angle as possible at a steady speed

Depress the clutch pedal and coast across the wet rails to prevent tyre spin

Accelerate sharply at a shallow angle to clear the metal surface quickly

Show answer & explanation

Answer: Cross the rails as close to a right angle as possible at a steady speed

Answer

Cross the rails as close to a right angle as possible at a steady speed

Crossing wet tram rails as close to a right angle as possible ensures the vehicle's tyres cross the low-grip metal quickly and prevents the tyres from sliding along the track or catching in the rail grooves. Keeping a steady speed without harsh braking or rapid acceleration preserves maximum tyre grip.

Step-by-Step Solution

Assess the surface hazard presented by wet metal tram rails embedded in the road.

Recognise that wet steel offers very low grip compared to asphalt and that rail grooves can catch or deflect vehicle tyres.

Rain dramatically lowers friction on polished metal surfaces, creating an immediate skid hazard.

Adjust vehicle approach angle and maintain smooth control inputs.

Steer across the rails as close to a 90-degree angle as traffic conditions allow, keeping throttle and steering steady without abrupt braking.

Crossing perpendicular to the tracks ensures tyres spend minimal time on the low-grip surface and prevents them from tracking along the groove.

Question 1169Question →

You are approaching a junction intending to turn right from a side road onto an urban one-way street that incorporates an operational contraflow bus lane. Which observation is essential before you emerge into the carriageway?

Buses flashing their headlights to indicate they are conceding priority to let you turn

Buses travelling against the general flow of traffic, requiring thorough scanning in both directions

Vehicles approaching exclusively from your right, as traffic on one-way streets only travels in a single direction

Parked buses standing at passenger boarding bays along the left-hand kerb

Show answer & explanation

Answer: Buses travelling against the general flow of traffic, requiring thorough scanning in both directions

Answer

Buses travelling against the general flow of traffic, requiring thorough scanning in both directions

A contraflow bus lane allows buses (and other authorised vehicles) to travel against the general one-way traffic flow. When emerging from a side road, drivers cannot rely on the usual assumption that all vehicles are approaching from a single direction; they must scan thoroughly in both directions before turning.

Step-by-Step Solution

Identify the specific road configuration and lane rules

Recognise that a contraflow bus lane permits buses to operate in the opposite direction to the normal flow of one-way traffic

Standard one-way street assumptions do not apply when contraflow lanes are present

Determine the necessary observation pattern before emerging

Scan both left and right across all lanes before making the right turn

Traffic will approach from both directions across your intended path of travel

Question 1170Question →

While following a cyclist on a wet road, you notice tram tracks embedded in the carriageway ahead. Why might the cyclist steer towards the centre of the lane?

To cross the rails as close to a right angle as possible to avoid skidding or catching their tyres in the groove

To create a safe gap on the left so that following traffic can overtake them on the inside

To signal to oncoming traffic that the cyclist has statutory right of way over oncoming vehicles

To force following drivers to stop immediately rather than continuing to drive behind them

Show answer & explanation

Answer: To cross the rails as close to a right angle as possible to avoid skidding or catching their tyres in the groove

Answer

To cross the rails as close to a right angle as possible to avoid skidding or catching their tyres in the groove

Tram tracks present a significant hazard to cyclists, particularly in wet conditions, because metal rails become extremely slippery and bicycle wheels can easily become trapped in the track grooves. The Highway Code advises that cyclists may need to move away from the kerb to cross tram rails at a right angle to stay upright and maintain control. Drivers following cyclists should anticipate this lateral movement, hang back, and give them plenty of room.

Step-by-Step Solution

Identify the hazard presented by wet tram tracks to two-wheeled vehicles

Tram rails are slippery when wet and have narrow recessed grooves that can trap bicycle wheels

Bicycle tyres are thin and prone to losing traction or jamming in track grooves if crossed at a shallow angle

Determine the necessary safety manoeuvre for the cyclist according to The Highway Code

The cyclist must steer centrally to cross the tracks at or near a right angle (90 degrees)

Crossing at a right angle prevents the tyres from slipping along the metal edge or falling into the track slot

Determine the appropriate driver expectation and response

Anticipate the cyclist moving away from the kerb, stay well back, and give them ample space

Vulnerable road users require room and time to navigate surface hazards safely without pressure from following vehicles

Question 1171Question →

When waiting to emerge from a junction, you should wait until an approaching motorcycle actually begins to turn before pulling out, even if its indicator is flashing.

True

False

Show answer & explanation

Answer: True

Answer

True — You must wait for the motorcycle to actively begin turning before emerging, as motorcycle indicators frequently do not self-cancel and may have been left flashing unintentionally.

The statement is correct because many motorcycles have manually operated indicators that do not automatically cancel once a manoeuvre is finished. A rider may have accidentally left their indicator flashing, or they may be intending to turn into an entrance further down the road. Drivers at junctions must always wait until the rider has actively committed to the turn before emerging into their path.

Step-by-Step Solution

Evaluate the visual information presented by the approaching motorcycle at the junction.

Identify that the motorcycle has a flashing directional indicator.

Observing approaching road users and their signals is essential for anticipating traffic flow.

Apply knowledge of motorcycle design and rider behaviour regarding turn signals.

Recognise that many motorcycle indicators require manual cancellation and may be flashing by mistake.

Unlike most modern passenger cars, many motorcycle models do not have self-cancelling indicators after completing a turn or lane change.

Determine the safe action before emerging onto the main carriageway.

Remain behind the give-way line until the motorcyclist has slowed down and clearly committed to turning.

Emerging solely based on a flashing indicator creates an immediate risk of a severe side-impact collision if the rider continues straight.

Question 1172Question →

You are attending a social gathering and plan to drive home later that evening. Why is it dangerous to rely on counting alcohol units to stay just under the legal limit?

Alcohol increases hazard reaction times only when driving at high speeds on motorways, not in urban traffic

Consuming food while drinking speeds up the breakdown of alcohol in the liver, eliminating it immediately

Any amount of alcohol impairs driving performance, and individual factors like body mass and food intake make blood alcohol levels unpredictable

Counting units is only required for drivers who hold a commercial licence, while car drivers are exempt

Show answer & explanation

Answer: Any amount of alcohol impairs driving performance, and individual factors like body mass and food intake make blood alcohol levels unpredictable

Answer

Any amount of alcohol impairs driving performance, and individual factors like body mass and food intake make blood alcohol levels unpredictable

Counting alcohol units is an unreliable and dangerous method for determining fitness to drive. Factors such as body mass, sex, metabolic rate, stress levels, and food consumption mean identical amounts of alcohol produce widely differing blood alcohol concentrations and impairment levels. Because even minor alcohol consumption degrades reaction times and hazard perception, the safest rule is to consume no alcohol when planning to drive.

Step-by-Step Solution

Assess the physiological effects of alcohol on driver hazard awareness and reaction capability

Even small quantities of alcohol degrade hazard anticipation, judgment of speed and distance, and motor coordination

Alcohol acts as a depressant on the central nervous system, slowing down neural processing

Evaluate the reliability of attempting to calculate exact blood alcohol concentration using standard units

Blood alcohol levels and impairment severity differ significantly between individuals based on weight, sex, metabolism, and food intake

Because unit counting cannot guarantee compliance or safety, the only safe approach is to consume no alcohol before driving

Question 1173Question →

You are driving on an unlit road and encounter thick fog. Why should you use dipped headlights rather than main beam headlights?

Main beam headlights reflect off the fog and create severe glare that reduces your forward visibility

Main beam headlights cause oncoming drivers to fixate solely on your vehicle rather than scanning the road ahead

Main beam headlights increase the thinking distance required to react to developing road hazards

Main beam headlights reduce tyre traction on road surfaces made damp by fog droplets

Show answer & explanation

Answer: Main beam headlights reflect off the fog and create severe glare that reduces your forward visibility

Answer

Main beam headlights reflect off the fog and create severe glare that reduces your forward visibility

In thick fog, light from main beam headlights bounces off the suspended moisture particles (backscatter), creating a wall of white glare that severely dazzles the driver and obscures the road. Dipped headlights aim light downward onto the road surface beneath the fog, providing clearer vision without reflection.

Step-by-Step Solution

Identify the optical effect of fog on vehicle lighting

Fog consists of millions of suspended water droplets that act like tiny mirrors.

Understanding how light interacts with moisture explains why high-angle beams create visual impairment.

Compare the beam angles of main beam and dipped headlights

Main beam projects straight ahead and upwards, reflecting light directly back at the driver. Dipped beam angles light down toward the road surface below the fog level.

Dipped headlights illuminate the carriageway without bouncing blinding glare back into the cabin.

Question 1175Question →

You are driving on a clear road when an unexpected hazard forces you to make an emergency stop. If your vehicle is fitted with an anti-lock braking system (ABS), how should you apply the footbrake?

Pump the brake pedal rapidly up and down to prevent the wheels from locking

Press the brake pedal rapidly and firmly, keeping it fully depressed until the vehicle stops

Apply the handbrake firmly at the same time as light pressure on the footbrake

Press the footbrake gently and release it several times to avoid skidding

Show answer & explanation

Answer: Press the brake pedal rapidly and firmly, keeping it fully depressed until the vehicle stops

Answer

Press the brake pedal rapidly and firmly, keeping it fully depressed until the vehicle stops

In an emergency stop with an anti-lock braking system (ABS), the driver should apply full and continuous pressure to the footbrake without releasing it. The system automatically regulates braking pressure to prevent the wheels from locking, ensuring maximum braking effort and preserving steering control.

Step-by-Step Solution

Identify the immediate emergency stopping requirement and recognize that the vehicle has ABS fitted.

The driver knows the electronic system will automatically prevent wheel lock-up.

ABS operates by sensing when wheels are about to lock and rapidly modulating brake pressure automatically.

Apply continuous, firm pressure to the brake pedal without releasing or pumping.

The vehicle achieves maximum deceleration while retaining steering control.

ABS requires constant system pressure to monitor wheel rotational speed and optimize braking grip.

Question 1176Question →

You are driving on a smart motorway where the hard shoulder can be opened as an active traffic lane. The overhead gantries are currently displaying a mandatory speed limit sign above the hard shoulder, as well as above the adjacent two lanes. The far right-hand lane has a red 'X' displayed above it. Traffic is light, and the active hard shoulder is completely clear ahead of you. You are currently driving in the lane immediately to the right of the active hard shoulder. According to motorway lane discipline rules, which action is correct?

Maintain your position in your current lane, as the active hard shoulder should only be used if you intend to leave the motorway at the next junction.

Maintain your position, because you should only enter a dynamic hard shoulder if the traffic in your current lane becomes heavily congested.

Move into the active hard shoulder, as it is operating as the normal left-hand lane and you must always keep to the leftmost open lane when the road ahead is clear.

Move one lane to your right to ensure the active hard shoulder remains completely clear for emergency vehicles and joining traffic.

Show answer & explanation

Answer: Move into the active hard shoulder, as it is operating as the normal left-hand lane and you must always keep to the leftmost open lane when the road ahead is clear.

Answer

The correct action is to move into the active hard shoulder, treating it as the normal left-hand driving lane.

When a smart motorway's hard shoulder is dynamically opened as a traffic lane (indicated by a speed limit sign displayed above it), it must be utilized as the normal left-hand lane. The fundamental rule of UK motorway lane discipline dictates that drivers must always keep to the leftmost available lane when the road ahead is clear. Therefore, if the active hard shoulder is clear, you must drive in it to avoid lane hogging.

Step-by-Step Solution

Analyze the overhead gantry signals.

A speed limit sign above the hard shoulder indicates it is currently open as a normal traffic lane.

You must verify the legal status of the hard shoulder before using it.

Determine the effective layout of the lanes.

The active hard shoulder is now effectively the new left-hand lane (Lane 1), and you are currently situated in Lane 2.

Lane numbering and positioning change dynamically on a smart motorway when the hard shoulder is opened.

Apply the fundamental rule of motorway lane discipline.

You must always drive in the left-hand lane when the road ahead is clear.

This rule prevents lane hogging and ensures a safe, predictable flow of traffic.

Formulate the correct driving action based on the rules.

Since the active hard shoulder is open and clear, you must move into it, rather than remaining in your current lane.

Staying in the second lane when the first is clear constitutes middle-lane hogging.

Question 1178Question →

An Anti-lock Braking System (ABS) allows a driver to maintain steering control while applying full braking pressure in an emergency.

True

False

Show answer & explanation

Answer: True

Answer

True

The statement is true because ABS automatically modulates hydraulic brake line pressure to stop wheels from locking completely, allowing the tyres to maintain traction so the driver can steer away from danger.

Step-by-Step Solution

Identify the primary function of an Anti-lock Braking System (ABS) during emergency braking.

ABS prevents the road wheels from locking and skidding when heavy pedal pressure is applied.

When wheels lock and slide across the road surface, steering control is lost because locked tyres cannot generate lateral forces.

Evaluate the effect of wheel rotation on directional control.

Because ABS keeps the wheels rotating by rapidly pulsing brake pressure, the tyres retain grip to steer.

This confirms that the driver is able to steer the vehicle while simultaneously braking heavily.

Question 1179Question →

On an unrestricted motorway, a standard light commercial van (not exceeding 3.5 tonnes maximum authorised mass) is subject to a lower statutory national speed limit than an ordinary passenger car.

True

False

Show answer & explanation

Answer: False

Answer

False. On an unrestricted motorway, both a standard light commercial van (under 3.5 tonnes) and an ordinary passenger car are subject to the same national speed limit of 70 mph.

Under UK Highway Code Rule 124, goods vehicles up to 7.5 tonnes maximum authorised mass share the standard 70 mph national speed limit on unrestricted motorways with ordinary cars. The lower statutory limits for light commercial vehicles (50 mph on single carriageways and 60 mph on dual carriageways) do not apply to motorways unless the vehicle is towing a trailer or articulated.

Step-by-Step Solution

Identify the vehicle category and road type specified in the scenario

Vehicle: Light commercial van (maximum authorised mass ≤ 3.5 tonnes), not towing; Road type: Unrestricted motorway.

Speed limits under the UK Highway Code depend on both vehicle classification and road classification.

Consult UK Highway Code Rule 124 speed limit regulations for motorways

For goods vehicles not exceeding 7.5 tonnes maximum laden weight, the motorway national speed limit is 70 mph unless towing.

Goods vehicles up to 7.5 tonnes share the passenger car limit on motorways.

Compare the van's motorway speed limit to that of an ordinary passenger car

Both vehicle types have an identical national speed limit of 70 mph on motorways.

The reduced limits for light goods vehicles apply only to single carriageways (50 mph) and dual carriageways (60 mph), not motorways.

Question 1180Question →

While driving along an untreated rural road in sub-zero temperatures, you notice that tyre noise has ceased and the steering suddenly feels unusually light and unresponsive as you approach a bend. What is the safest course of action to maintain vehicle control?

Brake firmly and steadily in a straight line before attempting to turn into the bend

Depress the clutch pedal and allow the vehicle to coast freely around the bend

Smoothly ease off the accelerator and avoid any sudden braking or sharp steering inputs

Rapidly shift down to first gear to utilise maximum engine braking immediately

Show answer & explanation

Answer: Smoothly ease off the accelerator and avoid any sudden braking or sharp steering inputs

Answer

Smoothly ease off the accelerator and avoid any sudden braking or sharp steering inputs

When driving on black ice, the steering feels light and tyre noise disappears due to the lack of friction. The safest response according to the Highway Code is to smoothly ease off the accelerator to reduce speed gradually, avoiding harsh braking, sudden steering inputs, or sudden gear changes that would break what little tyre grip remains.

Step-by-Step Solution

Identify the symptoms of black ice

Recognise that silent tyre noise and light steering signify zero or negligible surface grip

Early recognition prevents sudden reactive inputs that destabilise the vehicle

Manage throttle and speed without using the footbrake

Gently ease off the accelerator to let momentum decrease gradually

Harsh braking on ice will immediately lock the tyres and prevent the vehicle from steering

Maintain smooth, minimal steering corrections

Keep steering inputs progressive and deliberate to follow the curvature of the road

Sudden or aggressive steering angles cause the front tyres to slide uncontrollably across the ice
