On a dual carriageway where the national speed limit applies, a car towing a caravan is permitted to travel at a maximum speed of 70 mph.

True

False

Show answer & explanation

Answer: False

Answer

False

Under the UK Highway Code, the national speed limit on a dual carriageway for a car towing a caravan or trailer is 60 mph. A limit of 70 mph applies only to solo passenger cars, motorcycles, and car-derived vans.

Step-by-Step Solution

Identify the vehicle configuration and road category.

The vehicle is a car towing a caravan travelling on a dual carriageway.

National speed limits in the UK Highway Code vary based on vehicle classification and road type.

Determine the statutory speed limit for this combination under national speed limit rules.

The statutory maximum speed limit for a car towing a trailer or caravan on a dual carriageway is 60 mph.

Towing adds mass and reduces stability and braking efficiency, resulting in a 10 mph reduction compared to solo cars.

Evaluate the accuracy of the statement.

The statement claims the maximum permitted speed is 70 mph, which exceeds the legal 60 mph limit.

Since 70 mph is unlawful for a towing vehicle on a dual carriageway, the statement is false.

Question 1342Question →

While proceeding through a controlled motorway section, the overhead electronic sign displays flashing amber lights above your lane with a recommended speed of 40 mph. In this situation, what is the legal status and requirement of the displayed signal?

It sets a mandatory minimum speed limit that all vehicles must maintain to prevent traffic congestion.

It provides an advisory maximum speed warning of a hazard ahead, unlike a number enclosed in a red ring which is legally mandatory.

It is a legally enforceable mandatory limit requiring strict compliance, while a speed in a red circle serves purely as guidance.

It applies exclusively to heavy goods vehicles and passenger buses, allowing cars to proceed at the national speed limit if their lane is clear.

Show answer & explanation

Answer: It provides an advisory maximum speed warning of a hazard ahead, unlike a number enclosed in a red ring which is legally mandatory.

Answer

The displayed signal is an advisory maximum speed intended to warn drivers of an upcoming hazard, whereas a speed within a solid red ring is a legally enforceable mandatory limit.

Flashing amber lights on motorway gantries and electronic message signs are warning indicators. They advise drivers of upcoming hazards such as fog, collisions, or slow-moving queues and recommend a sensible maximum speed. In contrast, speeds enclosed within a solid red circle are variable mandatory speed limits that are legally enforceable under UK road traffic law.

Step-by-Step Solution

Identify the visual characteristics of the gantry signal.

The signal shows flashing amber lights with a numeric speed value rather than a solid red circle.

Recognising the sign type determines whether the instruction is advisory or regulatory under the Highway Code.

Determine the legal status of flashing amber motorway signals under UK law.

Flashing amber signals indicate temporary hazards, lane closures ahead, or adverse conditions, making the displayed speed an advisory maximum.

Highway Code Rule 257 specifies that flashing amber lights warn of hazards and advise an appropriate speed, whereas Rule 261 establishes that red circular rings denote mandatory limits.

Distinguish between advisory guidance and mandatory variable speed limits.

Select the option that correctly identifies the advisory nature of flashing amber lights and contrasts it with mandatory red rings.

Exceeding a mandatory limit is an absolute offence, whereas failing to heed advisory speeds increases collision risk in hazardous conditions.

Key Concept

Distinction between advisory gantry signals (flashing amber lights) and mandatory variable speed limits (red circular rings) on managed motorways.

Question 1343Question →

On a one-way street with two or more traffic lanes, drivers are permitted under the Highway Code to overtake other moving vehicles on either the left or the right side.

True

False

Show answer & explanation

Answer: True

Answer

True

The statement is true because Highway Code Rule 163 explicitly permits drivers to pass on either the left or the right when travelling on multi-lane one-way streets, provided observations and mirrors confirm it is safe to do so.

Step-by-Step Solution

Identify the road layout and regulatory context presented in the statement.

The scenario specifically describes a multi-lane one-way street.

Different road configurations carry specific overtaking regulations and exceptions under the Highway Code.

Review Highway Code Rule 163 regarding directional overtaking rules and their statutory exceptions.

The general principle is to overtake on the right, but explicit exceptions exist for one-way streets, vehicles turning right, and slow-moving congested queues.

Drivers must distinguish between general lane discipline rules and specific road-type exemptions.

Evaluate the legality of passing on either side on a one-way street.

Highway Code Rule 163 explicitly states that on one-way streets, traffic may pass on either side when safe.

In a one-way system, there is no oncoming traffic in adjacent lanes, allowing safe passage on either side.

Determine the truth value of the stem statement.

The statement accurately reflects UK driving law and Highway Code guidance.

The claim is fully true without legal ambiguity.

Question 1344Question →

You are waiting to turn right into a side road. An oncoming bus is slowing down and indicating left to turn into the same road. What hazard should you be especially alert for before turning across the oncoming carriageway?

The bus driver signalling following traffic to stop and give way to you

A motorcyclist travelling behind the bus who may be hidden from view and continuing straight ahead

A motorcyclist behind your vehicle being legally prohibited from filtering past on the left

Vehicles following the bus requiring shorter stopping distances if the road surface is wet

Show answer & explanation

Answer: A motorcyclist travelling behind the bus who may be hidden from view and continuing straight ahead

Answer

A motorcyclist travelling behind the bus who may be hidden from view and continuing straight ahead

Large vehicles such as buses and lorries can easily obscure smaller vehicles like motorcycles. When turning right across an oncoming lane, you must ensure that no hidden motorcyclist is travelling behind or alongside the turning vehicle before committing to the manoeuvre.

Step-by-Step Solution

Assess the visual obstruction created by the oncoming vehicle

You recognize that a large turning vehicle, such as a bus, blocks the view of oncoming traffic behind it.

Large vehicles create extensive blind zones on the carriageway that conceal smaller road users.

Anticipate hidden vulnerable road users before completing the turn

You hold your position until the oncoming lane behind the bus is clearly visible and safe to cross.

Motorcyclists travel faster and are narrower than cars, making them difficult to spot until the turning bus has fully cleared your line of sight.

Question 1345Question →

If you miss your intended exit on a motorway, you must continue driving to the next available exit.

True

False

Show answer & explanation

Answer: True

Answer

True

The statement is true because the Highway Code strictly requires drivers who miss their exit to proceed safely to the next junction, ensuring predictable movement and safety for all high-speed traffic.

Step-by-Step Solution

Recall the legal requirement and safety procedure when a motorway exit has been passed.

Highway Code Rule 273 dictates carrying on to the next junction without attempting to reverse or turn around.

High-speed traffic makes any attempt to reverse or change direction on a motorway extremely hazardous and illegal.

Question 1346Question →

You are driving a passenger car on a rural road that expands to provide two lanes in your direction of travel. The opposing flow of traffic is separated only by painted white line markings, with no central reservation or physical dividing barrier. In the absence of any speed limit signs, what is the maximum legal speed limit for your vehicle?

50 mph

60 mph

70 mph

30 mph

Show answer & explanation

Answer: 60 mph

Answer

60 mph

A road is legally a single carriageway unless there is a physical central reservation separating the opposing flows of traffic. Additional lanes or overtaking sections marked only by paint lines do not constitute a dual carriageway. Therefore, the national speed limit of 60 mph for a car on a single carriageway applies.

Step-by-Step Solution

Determine the legal classification of the road

Single carriageway

A road is only classified as a dual carriageway if the opposing directions of traffic are separated by a physical central reservation. Paint or extra lanes alone do not create a dual carriageway.

Identify the vehicle type and statutory national speed limit

Solo passenger car on a single carriageway = 60 mph

A circular white sign with a black diagonal stripe is displayed. What is the maximum permitted speed limit for your vehicle?

70 mph

60 mph

50 mph

30 mph

Show answer & explanation

Answer: 70 mph

Answer

70 mph

The defining characteristic of a dual carriageway is the physical central reservation separating the opposing traffic flows, not the number of lanes. Because the road has a central reservation and displays the national speed limit sign, the maximum permitted speed for a standard solo passenger car is 70 mph.

Step-by-Step Solution

Identify the road type based on the presence of a central reservation.

The road is classified as a dual carriageway.

According to the Highway Code, a dual carriageway is defined by the presence of a physical central reservation separating the carriageways, not by the number of traffic lanes.

Interpret the meaning of the road sign described.

The national speed limit applies.

A circular white sign with a black diagonal stripe is the official traffic sign indicating that the national speed limit applies to the road.

Determine the national speed limit for the specific vehicle and road combination.

The limit is 70 mph.

For a standard solo passenger car on a dual carriageway, the national speed limit is 70 mph.

Question 1349Question →

When driving in congested, slow-moving motorway traffic where vehicles are queued across all lanes, you are permitted to stay in your lane and pass traffic on your right if your lane is moving faster.

True

False

Show answer & explanation

Answer: True

Answer

True. Under congested conditions where traffic is moving in slow queues across all lanes, keeping pace with your lane and passing slower traffic on your right is permitted.

According to Highway Code Rule 268, when traffic is congested and moving in queues across all lanes, you are permitted to keep up with the flow of your lane and pass vehicles on your right, provided you stay in your lane and do not weave.

Step-by-Step Solution

Assess the overall traffic state and flow characteristics on the motorway.

Identify that the scenario describes slow-moving, congested queues across all lanes rather than free-flowing traffic.

Motorway lane discipline rules distinguish strictly between free-flowing overtaking and multi-lane queue management.

Apply Highway Code Rule 268 concerning passing on the left.

Recognise that staying in your lane and passing slower queues on your right is legal and permitted during heavy congestion, as long as you do not change lanes to undertake.

Active undertaking (weaving into a left lane to overtake) is dangerous, but maintaining lane progress within a moving queue maintains smooth traffic flow.

Question 1350Question →

According to the UK Highway Code, the overall stopping distance for a car travelling at $30\text{ mph}$ in dry conditions is $23\text{ metres}$ . Because tyre grip is reduced in wet weather, stopping distances are at least double those on a dry road. What is the minimum overall stopping distance, in metres, for a car travelling at $30\text{ mph}$ on a wet road?

Show answer & explanation

Answer: 46

Answer

The minimum overall stopping distance on a wet road at

30\text{ mph}

46\text{ metres}

Under Rule 126 and Rule 227 of the UK Highway Code, stopping distances in wet weather are at least double those on dry roads. For a car travelling at

30\text{ mph}

, the standard dry stopping distance is

23\text{ metres}

(

75\text{ feet}

). Multiplying this figure by

2

gives a wet stopping distance of

46\text{ metres}

(

150\text{ feet}

Step-by-Step Solution

Determine the dry stopping distance for a vehicle travelling at

30\text{ mph}

Dry stopping distance is

23\text{ metres}

(composed of

9\text{ metres}

thinking distance and

14\text{ metres}

braking distance).

The baseline dry road stopping distance is required before applying weather condition multipliers.

Apply the wet weather distance multiplier mandated by the UK Highway Code.

Multiply the dry distance by

2

23\text{ m} \times 2 = 46\text{ m}

Water on the road reduces tyre adhesion and increases braking distance, causing total stopping distance to at least double in wet conditions.

Key Concept

The UK Highway Code specifies that stopping distances at least double on wet roads compared to dry conditions.

Question 1351Question →

When experiencing severe drowsiness while driving on a motorway, pulling over onto the hard shoulder to take a short nap is an authorised and safe countermeasure.

True

False

Show answer & explanation

Answer: False

Answer

False. Stopping on the hard shoulder to rest or sleep is strictly prohibited under The Highway Code and poses a severe collision hazard.

Under The Highway Code, stopping on the hard shoulder, slip road, or emergency area is illegal except in a breakdown or genuine emergency. Drowsiness does not qualify as an emergency; drivers must exit the motorway or stop at an authorised service area.

Step-by-Step Solution

Evaluate the situation and the proposed countermeasure

The driver is suffering from fatigue on a motorway and considers using the hard shoulder to rest.

Recognising the hazard of driving while tired is essential, but the response must comply with road law.

Apply Highway Code regulations regarding hard shoulder usage

The hard shoulder is restricted to breakdowns, medical emergencies, or directions from authorised personnel.

Fatigue does not legally qualify as an emergency permitting a stop on the hard shoulder due to the extreme danger from high-speed traffic.

Determine the correct protocol for managing driver fatigue

The driver must maintain vehicle control, exit the motorway at the next junction or service station, and rest in a safe designated parking area.

This confirms that stopping on the hard shoulder is both unlawful and unsafe, making the statement false.

Key Concept

Question 1352Question →

When driving on a road covered with compacted snow or ice, suddenly shifting down into a low gear while travelling at speed is recommended to slow the vehicle down quickly without skidding.

True

False

Show answer & explanation

Answer: False

Answer

False - Abrupt downshifting creates sudden engine braking forces that can break tyre grip and cause the driven wheels to skid on icy or snow-covered surfaces.

The correct response is False because sudden changes in speed or abrupt engine braking on ice and snow can easily break tyre traction, leading to a loss of control. The Highway Code recommends keeping all controls smooth, gentle, and progressive, using the highest practical gear rather than violently dropping down gears.

Step-by-Step Solution

Evaluate the vehicle handling dynamics of sudden downshifting on slippery surfaces.

Shifting rapidly into a lower gear produces sudden engine drag on the driven wheels.

On compacted snow or ice, tyre adhesion is drastically reduced, meaning abrupt deceleration torque from the engine will easily exceed available friction.

Determine the correct Highway Code vehicle control technique for ice and snow.

Drivers must apply gentle, progressive braking in good time and maintain smooth, gradual gear changes.

Smooth inputs prevent abrupt transfers of weight or rotational resistance that trigger loss of directional control.

Question 1353Question →

On a motorway with three or more lanes, a coach with more than eight passenger seats and a maximum laden weight exceeding 7.5 tonnes is permitted to use the right-hand lane to overtake slower-moving vehicles.

True

False

Show answer & explanation

Answer: False

Answer

False. Heavy coaches exceeding 7.5 tonnes are legally prohibited from using the right-hand lane of a motorway with three or more lanes.

Under Highway Code Rule 265, passenger-carrying vehicles with more than eight passenger seats and a maximum laden weight exceeding 7.5 tonnes must not use the right-hand lane of a motorway with three or more lanes, making the statement false.

Step-by-Step Solution

Identify the vehicle category and weight specified in the statement.

The vehicle is a coach with more than eight passenger seats and a maximum laden weight exceeding 7.5 tonnes.

Vehicle category and maximum laden weight determine specific motorway lane restrictions.

Apply the motorway lane restriction rules under the Highway Code.

Passenger vehicles exceeding 7.5 tonnes with more than eight seats are restricted to the left and middle lanes on multi-lane motorways.

Rule 265 of the Highway Code explicitly forbids heavy passenger-carrying vehicles over 7.5 tonnes from using the right-hand lane on motorways with three or more lanes.

Evaluate the validity of the statement.

The statement asserts that such a coach is permitted to use the right-hand lane, which directly contradicts the legal restriction.

Because the rule strictly prohibits right-hand lane usage for this vehicle class, the statement is false.

On smart motorways and motorways under Active Traffic Management (ATM), electronic signals on overhead gantries and roadside signs display mandatory instructions and vital safety warnings. Match each smart motorway signal or display with its exact legal requirement and required driver action.

Click a left item, then click its matching right item

Show answer & explanation

Answer

The Red 'X' matches with the strict legal prohibition against driving in that lane; the speed limit in a red circle matches with the legally enforceable mandatory maximum speed limit; the flashing red lights above all lanes match with the mandatory instruction to stop before reaching the gantry; and the diagonal white arrow matches with the mandatory instruction requiring drivers to move across to the lane on the left.

Each smart motorway gantry signal has a distinct legal definition under the UK Highway Code. A red 'X' mandates that the specific lane is closed to all traffic; a numerical speed limit inside a red circle sets an enforceable mandatory maximum speed; horizontal flashing red pairs over all lanes mandate that all vehicles stop before the gantry; and a diagonal arrow requires drivers to merge safely into the indicated lane ahead of a closure.

Step-by-Step Solution

Evaluate the Red 'X' gantry signal

Identified as a mandatory lane closure prohibition (Highway Code Rule 258)

Red 'X' signals are legally binding closures used when stranded vehicles, emergency workers, or debris obstruct the lane.

Evaluate the speed limit displayed within a red circle

Identified as a mandatory maximum speed limit (Highway Code Rule 261)

Any speed sign enclosed within a red circle constitutes a statutory maximum speed limit rather than an advisory guideline.

Evaluate horizontal flashing red lights across all lanes with 'STOP'

Identified as an absolute motorway closure requiring all traffic to stop before the gantry

Flashing red lights spanning all carriageway lanes indicate immediate danger ahead, prohibiting any vehicle from passing the gantry.

Evaluate the diagonal lane divert arrow

Identified as an advance warning to change lanes safely in the indicated direction

The diagonal arrow alerts drivers to move out of the lane prior to an upcoming red 'X' gantry closure.

Question 1355Question →

After safely resolving an emergency breakdown on the hard shoulder of a conventional motorway, you are preparing to continue your journey. In what chronological sequence should you carry out the following actions to safely rejoin the carriageway?

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence begins with checking mirrors and blind spots, followed by accelerating along the hard shoulder to match traffic speed, then signalling right in good time, and finally merging smoothly into the left-hand lane when a safe gap appears.

According to Highway Code Rule 273, drivers rejoining the motorway from the hard shoulder must first observe around the vehicle, accelerate along the hard shoulder to match the speed of lane 1 traffic, signal right in good time, and merge smoothly into an adequate gap.

Step-by-Step Solution

Conduct 360-degree observations including rear mirrors and the offside blind spot.

Confirmation that the hard shoulder ahead is clear of debris or obstructions and that live lane traffic allows for an upcoming merge.

Moving off without proper observation risks colliding with stationary debris or misjudging fast-moving traffic in lane 1.

Move off and accelerate along the hard shoulder.

The vehicle reaches a speed comparable to vehicles travelling in lane 1.

Highway Code Rule 273 requires drivers to build up speed on the hard shoulder rather than pulling directly into high-speed live lanes from a standstill.

Apply the right-turn indicator in good time while maintaining matching speed.

Approaching road users are clearly alerted to the vehicle's intention to enter the live lane.

Clear signalling allows approaching motorway drivers time to adjust their positioning or maintain a suitable gap.

Steer smoothly into the left-hand running lane when a safe gap is identified.

The vehicle safely integrates into the active traffic flow without impeding other drivers.

Merging only when a safe gap appears completes the procedure safely without causing sudden braking behind.

Show answer & explanation

Answer: Stay in your lane and pass the slower-moving traffic on the left, keeping a safe distance

Answer

Stay in your lane and pass the slower-moving traffic on the left, keeping a safe distance

According to the Highway Code, you should normally overtake on the right. However, an exception applies in congested conditions where traffic is moving in slow queues: if the queue in the lane to your right is moving slower than your lane, you may keep up with the traffic in your lane and pass on the left.

Step-by-Step Solution

Assess the motorway traffic conditions and lane flow

Identify that traffic is travelling in congested, slow-moving queues across adjacent lanes

Highway Code Rule 268 permits passing on the left when queues of traffic in adjacent lanes are moving at varying speeds

50 mph

60 mph

70 mph

Show answer & explanation

Answer: 60 mph

Answer

60 mph is the maximum legal speed permitted for a car-derived van on a single carriageway road.

Car-derived vans with a maximum laden weight of up to 2 tonnes are legally treated the same as standard passenger cars under the UK Highway Code. On single carriageways where the national speed limit applies, the maximum speed is 60 mph.

Step-by-Step Solution

Determine the vehicle category and weight classification

The vehicle is a car-derived van weighing less than 2 tonnes maximum laden weight, which shares the same statutory speed allowances as standard passenger cars.

The Highway Code grants car-derived vans under 2 tonnes passenger car speed limits rather than commercial goods vehicle limits.

Identify the road layout and the governing limit

The road is a single carriageway subject to the national speed limit.

National speed limits vary by road classification (single carriageway, dual carriageway, or motorway).

Apply the statutory speed limit rule

The national speed limit for cars and car-derived vans on single carriageways is 60 mph.

in dry conditions, the average thinking distance is

12\text{ metres}

(

40\text{ feet}

) and the braking distance is

24\text{ metres}

(

80\text{ feet}

). Adding these together gives an overall stopping distance of

36\text{ metres}

(

118\text{ feet}

Step-by-Step Solution

Identify the thinking distance at

40\text{ mph}

Thinking distance =

12\text{ metres}

(

40\text{ feet}

)

Thinking distance is the distance travelled in the time it takes to react to a hazard.

Identify the braking distance at

40\text{ mph}

Braking distance =

24\text{ metres}

(

80\text{ feet}

)

Braking distance is the distance travelled from pressing the brake pedal to coming to a complete stop.

Calculate the total stopping distance

Total stopping distance =

12\text{ metres} + 24\text{ metres} = 36\text{ metres}

(

Question 1359Question →

When driving at 50 mph on a wet road, a driver's total stopping distance doubles from the standard dry-road figure of 53 metres (175 feet) to 106 metres (350 feet) because both thinking distance and braking distance are doubled by reduced tyre grip.

True

False

Show answer & explanation

Answer: False

Answer

False

The statement is false because reduced tyre grip on wet surfaces only increases the physical braking distance (doubling it from 38 metres to 76 metres at 50 mph). The thinking distance remains 15 metres because road surface conditions do not affect driver reaction time. As a result, the total stopping distance becomes 91 metres (300 feet), rather than 106 metres.

Step-by-Step Solution

Identify the components of total stopping distance at 50 mph under standard dry conditions.

Total stopping distance (53 m / 175 ft) consists of Thinking Distance (15 m / 50 ft) and Braking Distance (38 m / 125 ft).

Total stopping distance is the exact mathematical sum of reaction (thinking) distance and physical braking distance.

Analyze how wet weather specifically affects each distinct component.

Water on the road reduces tyre grip, which doubles physical braking distance from 38 m to 76 m. Thinking distance is determined solely by vehicle speed and driver reaction time, remaining unchanged at 15 m.

Surface moisture affects mechanical tyre-road friction, not human neurological perception and reaction time.

Calculate the actual stopping distance in wet conditions and evaluate the statement.

The total wet stopping distance is 15 m + 76 m = 91 m (approx. 300 ft). The claim that thinking distance doubles or that the total stopping distance equals 106 m is incorrect.

The statement mistakenly assumes thinking distance doubles due to reduced tyre grip.

Show answer & explanation

Answer: Slow down to 10 mph or less and pass leaving at least 2 metres of clearance

Answer

Slow down to 10 mph or less and pass leaving at least 2 metres of clearance

Under Highway Code Rules 163 and 215, drivers must pass horse riders and horse-drawn vehicles at speeds under 10 mph and allow at least 2 metres (6.5 feet) of lateral space, without making sudden loud noises or revving the engine.

Step-by-Step Solution

Identify the vulnerable road user and relevant Highway Code rules

Recognise that horses are easily frightened by speed, proximity, and sudden noise

Rule 163 and Rule 215 of the Highway Code specify clear safety limits for passing horses

Apply the legal speed and clearance requirements

Reduce speed to no more than 10 mph and allow at least 2 metres (6.5 feet) of lateral clearance

This prevents spooking the horse and provides adequate room if the horse moves unexpectedly
