Question 1Rules of the Road and road safety (bus/truck categories)

Under the Rules of the Road, what is the general default speed limit on a national secondary road outside a built-up area, unless signs show otherwise?

  1. 100 km/h
  2. 80 km/h Correct answer.
  3. 120 km/h
  4. 50 km/h

Explanation

The default speed limit for national secondary roads is 80 km/h. National primary roads (N roads) generally carry a 100 km/h default, while motorways carry 120 km/h. Drivers of buses and trucks must also respect any lower limit posted and any vehicle-specific restriction.

Question 2Rules of the Road and road safety (bus/truck categories)

You are driving a bus on a two-lane road and approach a pedestrian crossing where a person is waiting to cross. What must you do?

  1. Move to the centre line and pass the crossing quickly
  2. Continue at the same speed if no one has stepped out
  3. Sound the horn to warn them and continue
  4. Slow down and be prepared to stop to let them cross Correct answer.

Explanation

A driver approaching a pedestrian crossing must yield to pedestrians who are crossing or clearly about to cross. Slowing down and preparing to stop is the required response. Sounding the horn or accelerating past a waiting pedestrian is unsafe and contrary to the Rules of the Road.

Question 3Rules of the Road and road safety (bus/truck categories)

What is the maximum permitted blood alcohol concentration for a learner, novice or professional driver in Ireland?

  1. 20 mg per 100 ml of blood Correct answer.
  2. 80 mg per 100 ml of blood
  3. 50 mg per 100 ml of blood
  4. Zero, with no measurable level allowed

Explanation

Learner, novice and professional drivers, which includes bus and truck drivers, are subject to a lower legal limit of 20 mg of alcohol per 100 ml of blood. The general limit for other experienced drivers is 50 mg. Because professional drivers fall into the stricter category, even small amounts of alcohol can put them over the limit.

Question 4Rules of the Road and road safety (bus/truck categories)

How should you use a hard shoulder on a motorway when driving a truck?

  1. For overtaking slower vehicles on the left
  2. For short rest stops while you check a map
  3. Only for stopping in an emergency or breakdown Correct answer.
  4. As a normal driving lane when traffic is heavy

Explanation

The hard shoulder is reserved for emergencies, breakdowns and, in some cases, emergency vehicles. It is not a driving lane and must not be used to overtake or to take routine breaks. Pulling onto it for non-emergency reasons is dangerous and illegal.

Question 5Rules of the Road and road safety (bus/truck categories)

In a built-up area, what is the general default speed limit unless signs indicate otherwise?

  1. 40 km/h
  2. 60 km/h
  3. 30 km/h
  4. 50 km/h Correct answer.

Explanation

The default speed limit in built-up areas, known as special speed limit areas, is 50 km/h. Some areas such as housing estates or near schools may have lower posted limits. Drivers must always follow the posted signs and drive to the conditions.

Question 6Rules of the Road and road safety (bus/truck categories)

What does a continuous white line in the centre of the road mean for a bus driver?

  1. You must not cross it, except to avoid an obstruction Correct answer.
  2. You may cross it only when carrying passengers
  3. You may cross it to overtake if the road ahead is clear
  4. You may cross it to enter a side road on the right

Explanation

A continuous white centre line means you must not cross it to overtake or change lanes. The main exception is to avoid a stationary obstruction, provided it is safe to do so. Crossing it otherwise is an offence.

Question 7Rules of the Road and road safety (bus/truck categories)

What is the minimum legal tread depth for the tyres of a bus or truck in Ireland?

  1. 2.5 mm
  2. 1.6 mm
  3. 1.0 mm Correct answer.
  4. 3.0 mm

Explanation

For vehicles over 3,500 kg, which includes buses and trucks, the minimum tyre tread depth is 1.0 mm. Cars and other light vehicles must meet a 1.6 mm minimum. Tyres must also be free of defects and correctly inflated for safe operation.

Question 8Rules of the Road and road safety (bus/truck categories)

When are you permitted to use the horn while driving in a built-up area?

  1. To greet another driver you recognise
  2. To signal that you intend to overtake
  3. To express annoyance at a delay
  4. To warn other road users of danger Correct answer.

Explanation

The horn should only be used to warn other road users of danger. It must not be used as a greeting, to show annoyance, or to signal an intention to overtake. In built-up areas, unnecessary use of the horn is discouraged and may be an offence.

Question 9Rules of the Road and road safety (bus/truck categories)

A bus driver is approaching a junction where a garda is directing traffic with hand signals that conflict with the traffic lights. Which instruction takes priority?

  1. The road markings at the junction
  2. The hand signals of the garda Correct answer.
  3. The traffic lights, because they are automated
  4. The driver's own judgement of the safest route

Explanation

When a garda is directing traffic, their hand signals override both traffic lights and road markings. Drivers must obey the garda's directions even if the lights show a different instruction. This rule ensures safe control of traffic during incidents or heavy flows.

Question 10Rules of the Road and road safety (bus/truck categories)

You are driving a truck and your vehicle is involved in a collision that causes injury to a person. What must you do first?

  1. Move the vehicle away before stopping
  2. Drive on if the injury appears minor
  3. Continue to the nearest depot and report it later
  4. Stop, provide assistance and exchange details Correct answer.

Explanation

Following a collision causing injury, the driver must stop, offer reasonable assistance and exchange details with the other parties. Failing to stop is a serious offence. The scene should only be moved where it is safe and necessary to prevent further danger.

Question 11Rules of the Road and road safety (bus/truck categories)

What does a broken white centre line on a road indicate to a bus driver?

  1. You may cross it to overtake when it is safe Correct answer.
  2. You must not change lanes for any reason
  3. The road is one-way only
  4. Overtaking is prohibited at all times

Explanation

A broken white centre line may be crossed to overtake or change lanes, provided it is safe and there is sufficient clear road ahead. Drivers must judge visibility, oncoming traffic and their own vehicle's performance. Crossing is not permitted where a continuous line is present.

Question 12Rules of the Road and road safety (bus/truck categories)

When must a driver of a bus or truck use dipped headlights during the day?

  1. Only when it is raining heavily
  2. Only between the hours of sunset and sunrise
  3. Only on motorways
  4. In poor visibility such as fog, heavy rain or falling snow Correct answer.

Explanation

Dipped headlights must be used when visibility is seriously reduced by fog, heavy rain, snow or similar conditions. This helps other road users see the vehicle and improves the driver's own view. Dipped beams should also be used at night where street lighting is absent or inadequate.

Question 13Rules of the Road and road safety (bus/truck categories)

What is the correct action when a bus approaches a level crossing with red lights flashing and the barrier beginning to lower?

  1. Stop and wait until the lights stop flashing and the barriers are fully raised Correct answer.
  2. Sound the horn and continue across
  3. Stop on the crossing until the barrier lifts
  4. Proceed quickly before the barrier lowers completely

Explanation

Flashing red lights at a level crossing mean you must stop and wait. You should not proceed until the lights have stopped flashing and the barriers are fully raised. Stopping on the crossing itself is dangerous and must be avoided.

Question 14Rules of the Road and road safety (bus/truck categories)

How should a driver of a heavily loaded truck adjust their driving on a wet road?

  1. Follow the vehicle ahead more closely for shelter
  2. Allow a longer stopping distance and reduce speed Correct answer.
  3. Increase speed to clear surface water quickly
  4. Brake sharply to test the grip

Explanation

Wet roads reduce grip and increase stopping distances, especially for heavy vehicles with large momentum. Drivers should reduce speed and leave a greater gap to the vehicle ahead. Sharp braking on a wet surface can cause skidding or jack-knifing.

Question 15Rules of the Road and road safety (bus/truck categories)

What is the purpose of a bus lane marked on the road?

  1. To allow trucks to overtake slower traffic
  2. To reserve the lane for buses, and in some cases taxis and cyclists, during specified hours Correct answer.
  3. To provide parking space for buses
  4. To allow any vehicle to use it during rush hour

Explanation

A bus lane is reserved for buses and, depending on the signage, may also be used by taxis and cyclists during the hours shown. Other vehicles must not enter it during those times. The signage at the start of the lane sets out who may use it and when.

Question 16Rules of the Road and road safety (bus/truck categories)

A truck driver is about to reverse into a loading bay on a busy street. What is the safest approach?

  1. Ask a competent person to guide you and check all mirrors and blind spots Correct answer.
  2. Rely on the reversing camera alone and reverse quickly
  3. Reverse without assistance to avoid delay
  4. Sound the horn continuously and reverse at speed

Explanation

Reversing a large vehicle in a busy area carries serious risk because of blind spots. A competent guide should be used where possible, and the driver must check mirrors and blind spots throughout. Cameras and sensors assist but do not replace direct observation.

Question 17Rules of the Road and road safety (bus/truck categories)

What does a yellow box junction marking require of a truck driver?

  1. You must stop inside the box to wait for a gap
  2. You must always avoid the box even when turning left
  3. You may enter whenever the lights are green regardless of exit
  4. You may enter only if your exit is clear, apart from when turning right and blocked by oncoming traffic Correct answer.

Explanation

A yellow box junction must not be entered unless the exit is clear and you can clear it without stopping. The exception is when turning right and you are prevented from doing so by oncoming traffic. Blocking the box obstructs cross traffic and is an offence.

Question 18Rules of the Road and road safety (bus/truck categories)

What is the legal maximum number of hours a professional bus driver may drive without a break under driving time rules?

  1. 6 hours
  2. 8 hours
  3. 4 hours 30 minutes Correct answer.
  4. 2 hours

Explanation

Under EU driving time rules, a driver must take a break after 4 hours 30 minutes of driving at the latest. A break of at least 45 minutes is required, which may be split in certain ways. These rules apply to professional bus and truck drivers to reduce fatigue.

Question 19Rules of the Road and road safety (bus/truck categories)

You are driving a bus and a ball rolls into the road from between parked cars. What is the best response?

  1. Maintain speed because the ball is small
  2. Slow down and be prepared to stop in case a child follows Correct answer.
  3. Swerve into the opposite lane to avoid it
  4. Brake hard and sound the horn repeatedly

Explanation

A ball entering the road is a strong warning that a child may follow. The safest response is to reduce speed and be ready to stop, while checking mirrors for traffic behind. Swerving into oncoming traffic can create a more serious hazard.

Question 20Rules of the Road and road safety (bus/truck categories)

What is the correct way for a bus driver to enter a roundabout?

  1. Always stop at the entry line regardless of traffic
  2. Give way to traffic already on the roundabout coming from the right Correct answer.
  3. Give way only to vehicles already indicating left
  4. Enter at speed to merge ahead of circulating traffic

Explanation

At a roundabout, you must yield to traffic already circulating, which generally approaches from your right. You should enter only when there is a safe gap. Stopping unnecessarily when the way is clear can disrupt traffic flow.

Question 21Rules of the Road and road safety (bus/truck categories)

A truck's load overhangs the rear of the vehicle. What requirement applies before the vehicle is used on a public road?

  1. The load may be carried only at night
  2. No marking is needed if the overhang is under 2 metres
  3. The driver must obtain a written permit for every journey
  4. A warning device or marker must be fitted to make the projection visible Correct answer.

Explanation

Where a load projects beyond the rear of a vehicle, a warning device or marker must be fitted so the projection is clearly visible to other road users. The load must also be secure and within legal limits. Visibility of the overhang is essential to prevent collisions.

Question 22Rules of the Road and road safety (bus/truck categories)

A bus driver is following a cyclist on a narrow rural road with limited passing space. What is the safest action?

  1. Overtake closely to minimise time alongside the cyclist
  2. Accelerate and pass on a blind bend
  3. Sound the horn to make the cyclist move over
  4. Wait behind until there is a safe gap and leave generous clearance when passing Correct answer.

Explanation

Cyclists need generous clearance when being overtaken, and passing should only happen where there is a safe gap with good visibility. Waiting behind is the correct choice on a narrow road with limited space. Passing on a blind bend risks a head-on collision.

Question 23Rules of the Road and road safety (bus/truck categories)

A truck driver's vehicle has an air-brake system and the low-pressure warning activates while driving. What is the correct response?

  1. Pump the brakes repeatedly while accelerating
  2. Ignore it if the brakes still feel normal
  3. Stop safely as soon as possible and investigate before continuing Correct answer.
  4. Continue to the destination and report it at the depot

Explanation

A low-pressure warning on an air-brake system signals that braking performance may be compromised. The driver should bring the vehicle to a safe stop as soon as possible and not continue until the fault is resolved. Continuing to drive risks brake failure.

Question 24Rules of the Road and road safety (bus/truck categories)

Under the driver CPC requirements, what is the purpose of periodic training for professional bus and truck drivers?

  1. To certify that a vehicle is roadworthy
  2. To keep professional drivers' skills and knowledge up to date throughout their careers Correct answer.
  3. To replace the initial driving test for new drivers
  4. To allow drivers to exceed normal driving hours

Explanation

Periodic CPC training is designed to maintain and update the skills and knowledge of professional drivers throughout their careers. It covers areas such as safety, regulations and fuel efficiency. It does not replace the driving test or certify vehicle roadworthiness.

Question 25Rules of the Road and road safety (bus/truck categories)

A truck is descending a long steep hill with a full load. What is the safest braking technique?

  1. Coast in neutral to save fuel
  2. Rely on the footbrake continuously throughout the descent
  3. Accelerate at the top to carry momentum down
  4. Select a low gear before the descent and use engine braking to control speed Correct answer.

Explanation

On a long descent, selecting a low gear before the hill and using engine braking helps control speed and prevents brake fade. Continuous use of the footbrake can overheat the brakes and reduce their effectiveness. Coasting in neutral removes engine braking and is unsafe.

Question 26Rules of the Road and road safety (bus/truck categories)

What is the maximum permitted weight of a vehicle that may be driven on a public road in Ireland with an ordinary category B driving licence?

  1. 1,500 kg
  2. 5,500 kg
  3. 7,500 kg
  4. 3,500 kg Correct answer.

Explanation

A category B licence covers vehicles with a design gross vehicle weight of up to 3,500 kg, with seating for up to eight passengers besides the driver. Anything heavier, such as a bus or truck, requires the appropriate higher category.

Question 27Rules of the Road and road safety (bus/truck categories)

A bus driver is convicted of a road traffic offence and receives penalty points. What is the effect on the driver's licence?

  1. The points apply only to the vehicle owner, not the driver
  2. The points remain on the licence record for three years and can lead to disqualification if the threshold is reached Correct answer.
  3. The points are removed once the fine is paid
  4. The points expire after twelve months in all cases

Explanation

Penalty points stay on a driver's record for three years from the date they are applied. If the accumulated total reaches the disqualification threshold, the driver is put off the road for a set period.

Question 28Rules of the Road and road safety (bus/truck categories)

What does a flashing amber light at a pelican crossing require a bus driver to do?

  1. Stop and remain stationary until the light turns green
  2. Yield to pedestrians already on the crossing and proceed only when it is clear Correct answer.
  3. Sound the horn to warn pedestrians before continuing
  4. Treat the crossing exactly as a red light and stop completely

Explanation

At a pelican crossing the flashing amber phase means drivers must give way to any pedestrian already crossing. If no one is on the crossing, the driver may continue with due care.

Question 29Rules of the Road and road safety (bus/truck categories)

A bus driver is driving at night on an unlit road and an oncoming vehicle approaches. What should the driver do with the headlights?

  1. Switch to full main beam to be seen more clearly
  2. Use only the sidelights until the vehicle has passed
  3. Dip the headlights to avoid dazzling the other driver Correct answer.
  4. Turn the headlights off briefly until the vehicle passes

Explanation

Dipped headlights must be used when meeting oncoming traffic at night so the other driver is not dazzled. Main beam is reserved for stretches of road where no other road user is affected.

Question 30Rules of the Road and road safety (bus/truck categories)

What is the general speed limit on a motorway in Ireland for a bus or truck?

  1. 120 km/h
  2. 90 km/h
  3. 100 km/h
  4. 80 km/h Correct answer.

Explanation

Buses and goods vehicles are subject to a lower motorway limit than cars. The general maximum for these categories on a motorway is 80 km/h, regardless of the car limit on the same stretch.

Question 31Rules of the Road and road safety (bus/truck categories)

A truck driver notices that the load has shifted during the journey and is now unevenly distributed. What should the driver do?

  1. Ask a passenger to hold the load in place while moving
  2. Stop in a safe place and secure or redistribute the load before continuing Correct answer.
  3. Increase speed to reach the destination sooner
  4. Continue to the destination and report it at the end of the shift

Explanation

A load must be secured so that it cannot move or fall from the vehicle. If it shifts, the driver must stop safely and correct the problem before driving on, because an unstable load affects steering and braking.

Question 32Rules of the Road and road safety (bus/truck categories)

When should a bus driver switch on the vehicle's hazard warning lights?

  1. Whenever the bus is reversing into a bus stop
  2. While driving in heavy rain to improve visibility
  3. When the bus is stationary and causing a potential obstruction or hazard to other traffic Correct answer.
  4. When approaching a pedestrian crossing

Explanation

Hazard lights warn other road users that the vehicle is temporarily obstructing traffic or is a hazard, for example when broken down. They are not a substitute for normal indicators or for care when reversing.

Question 33Rules of the Road and road safety (bus/truck categories)

What must a bus driver do before opening the doors to let passengers alight at a stop?

  1. Open the doors while still moving slowly to save time
  2. Stop close to the kerb and check mirrors for cyclists or pedestrians before opening Correct answer.
  3. Stop in the centre of the lane and open the doors
  4. Rely on passengers to check for traffic themselves

Explanation

The bus should be brought to a stop close to the kerb and the driver should check mirrors and blind spots before opening doors. This protects passengers stepping out and cyclists passing on the left.

Question 34Rules of the Road and road safety (bus/truck categories)

A bus driver is approaching a junction and the traffic lights are out of order. How should the driver proceed?

  1. Assume oncoming traffic must give way to the bus
  2. Slow down, be prepared to stop and give way as at an uncontrolled junction Correct answer.
  3. Stop and wait until the lights are repaired
  4. Proceed at normal speed because the lights are off

Explanation

When traffic lights fail, the junction is treated as uncontrolled. The driver must approach with caution, be ready to stop, and apply the normal right-of-way rules for uncontrolled junctions.

Question 35Rules of the Road and road safety (bus/truck categories)

A truck driver intends to make a left turn into a narrow street. What is the main risk the driver must manage?

  1. The load becoming lighter as the vehicle turns
  2. The front wheels losing grip on the road surface
  3. The rear of the vehicle cutting in across the kerb or a cyclist on the inside Correct answer.
  4. The engine overheating during the turn

Explanation

Long vehicles sweep a tighter path at the rear wheels, so the rear can mount the kerb or strike a cyclist or pedestrian on the inside of the turn. The driver should take the turn wide where safe and check mirrors throughout.

Question 36Rules of the Road and road safety (bus/truck categories)

A bus driver is travelling on a two-lane national road and wishes to overtake a slower tractor. What must the driver confirm before starting the manoeuvre?

  1. That the road behind is clear of traffic only
  2. That there is a sufficient clear gap ahead, no oncoming traffic and overtaking is permitted by the road markings Correct answer.
  3. That the bus has enough fuel for the journey
  4. That the tractor has signalled an intention to turn off

Explanation

Overtaking requires a clear view, a safe gap ahead and no oncoming traffic, and the road markings must allow it. A continuous white line or a hazard such as a bend or crest forbids the manoeuvre.

Question 37Rules of the Road and road safety (bus/truck categories)

A truck is required to stop at a railway level crossing with a barrier that is raised and no lights showing. What should the driver do?

  1. Stop on the tracks to check for trains
  2. Slow down, look both ways and cross only when satisfied no train is approaching Correct answer.
  3. Sound the horn continuously while crossing
  4. Accelerate across without slowing because the barrier is raised

Explanation

Even when the barrier is raised, the driver should approach with care and check both directions before crossing. Stopping on the tracks is dangerous because a train could arrive while the vehicle is in the crossing.

Question 38Rules of the Road and road safety (bus/truck categories)

A bus driver is driving in fog with visibility reduced to about 50 metres. Which lighting should be used?

  1. Main beam headlights to see further ahead
  2. Sidelights only
  3. Dipped headlights and fog lights if fitted, keeping speed low Correct answer.
  4. Hazard warning lights while continuing at normal speed

Explanation

In fog, dipped headlights give the best balance of being seen and seeing ahead, and fog lights may be used when visibility is seriously reduced. Main beam reflects off the fog and reduces visibility further.

Question 39Rules of the Road and road safety (bus/truck categories)

A truck driver is parked at the roadside at night on an unlit road outside a built-up area. What lighting must the vehicle show?

  1. Parking lights, or hazard lights if the vehicle is a hazard to others Correct answer.
  2. Main beam headlights
  3. No lights are required if the vehicle is off the carriageway
  4. Interior cab light only

Explanation

A vehicle parked on an unlit road at night must show parking lights so it can be seen by other road users. If the position creates a particular hazard, hazard warning lights should also be used.

Question 40Rules of the Road and road safety (bus/truck categories)

A bus driver is approaching a school warden who has stepped onto the road with a stop sign raised. What must the driver do?

  1. Slow down and pass the warden with care
  2. Sound the horn and proceed
  3. Stop and remain stopped until the warden has returned to the footpath Correct answer.
  4. Continue if no children are visible

Explanation

A school warden displaying a stop sign has legal authority to halt traffic. The driver must stop and stay stopped until the warden lowers the sign and returns to the footpath.

Question 41Rules of the Road and road safety (bus/truck categories)

A truck driver is about to drive a vehicle with a trailer and must check the coupling. What is the most important check?

  1. That the trailer is empty
  2. That the trailer is painted in a visible colour
  3. That the coupling is fully engaged and locked and the safety connection is fitted Correct answer.
  4. That the trailer tyres are the same brand as the tractor unit

Explanation

The critical safety check is that the coupling is fully engaged and locked and that the breakaway safety connection is properly attached. A trailer that separates from the towing vehicle is extremely dangerous.

Question 42Rules of the Road and road safety (bus/truck categories)

A bus driver is stopped at a bus stop and a passenger with reduced mobility needs more time to board. What should the driver do?

  1. Ask other passengers to assist and depart on schedule
  2. Wait until the passenger is safely seated or secure before moving off Correct answer.
  3. Close the doors and continue to the next stop
  4. Move off slowly while the passenger is still boarding

Explanation

The driver must allow passengers with reduced mobility enough time to board and reach a safe position before moving off. Moving while someone is still boarding risks a serious fall.

Question 43Rules of the Road and road safety (bus/truck categories)

A truck driver is descending a road where the speed limit is 80 km/h but the vehicle is heavily loaded and the bend ahead is sharp. What is the correct approach?

  1. Change to a higher gear to slow the vehicle
  2. Maintain the speed limit exactly to avoid holding up traffic
  3. Reduce speed before the bend so the vehicle can be controlled without harsh braking Correct answer.
  4. Brake sharply only once in the bend

Explanation

Speed should be reduced before entering a bend, especially with a heavy load, so the vehicle remains stable and under control. Braking hard in a bend can cause a skid or loss of control.

Question 44Rules of the Road and road safety (bus/truck categories)

A bus driver is driving in a built-up area and a pedestrian steps onto a zebra crossing ahead. What is the legal obligation?

  1. Continue if the pedestrian has not yet reached the centre of the road
  2. Sound the horn to warn the pedestrian
  3. Yield to the pedestrian and allow them to cross Correct answer.
  4. Overtake the pedestrian on the crossing

Explanation

Drivers must yield to pedestrians on a zebra crossing and allow them to cross in safety. The obligation applies as soon as a pedestrian is on the crossing.

Question 45Rules of the Road and road safety (bus/truck categories)

An articulated truck driver is entering a roundabout with three lanes. What is the safest lane position for taking the second exit?

  1. Straddle two lanes to prevent cars passing
  2. Approach in the appropriate left lane and keep to it through the roundabout Correct answer.
  3. Approach in the right lane and cut across to the exit
  4. Approach in the left lane and signal right throughout

Explanation

For an exit past the first one, the driver should approach in the appropriate lane, usually the left lane unless markings indicate otherwise, and keep to that lane. Straddling lanes or cutting across is dangerous for other road users.

Question 46Rules of the Road and road safety (bus/truck categories)

A bus driver's vehicle has a retarder fitted. When is it most useful on a long mountain descent?

  1. To increase engine power on the climb
  2. To supplement the service brakes and reduce the risk of brake fade Correct answer.
  3. To replace the service brakes entirely on steep descents
  4. To operate the hazard lights automatically

Explanation

A retarder provides auxiliary braking on long descents, reducing reliance on the service brakes and helping to prevent overheating and fade. It supplements rather than replaces the service brakes.

Question 47Rules of the Road and road safety (bus/truck categories)

A truck driver is planning a journey and must comply with tachograph rules. What is the purpose of recording driving time, breaks and rest periods?

  1. To record the vehicle's maintenance history
  2. To determine the route taken by the vehicle
  3. To allow enforcement of driving and rest time limits for road safety Correct answer.
  4. To calculate the vehicle's fuel consumption

Explanation

Tachograph records allow authorities to check compliance with driving time, break and rest requirements. These rules exist to prevent driver fatigue, which is a major cause of serious collisions involving heavy vehicles.

Question 48Rules of the Road and road safety (bus/truck categories)

A bus driver is driving on a motorway and the vehicle develops a puncture. What is the safest sequence of actions?

  1. Stop immediately in the right lane and change the wheel
  2. Continue to the next exit on the flat tyre
  3. Stop in the middle lane and switch on hazard lights
  4. Move to the hard shoulder, stop as far left as possible and place a warning triangle well behind the vehicle Correct answer.

Explanation

On a motorway the driver should reach the hard shoulder and stop as far left as possible, then place a warning triangle well behind the vehicle if it is safe to do so. Stopping in a live lane exposes the vehicle and its occupants to serious risk.

Question 49Rules of the Road and road safety (bus/truck categories)

A truck driver is carrying a load that projects beyond the rear of the vehicle. What is required before the vehicle is used on a public road?

  1. The load must be removed and the journey cancelled
  2. The driver must obtain a written permit from the local authority
  3. The vehicle must display hazard warning lights at all times
  4. The projection must be clearly marked so other road users can see it Correct answer.

Explanation

A load that projects beyond the vehicle must be marked so it is visible to other road users, for example with a warning flag or marker. This reduces the risk of other drivers misjudging the vehicle's length.

Question 50Rules of the Road and road safety (bus/truck categories)

A bus driver is approaching a junction where a stop sign is partially obscured by foliage. What is the safest action?

  1. Treat the junction as a stop junction, stop and check before proceeding Correct answer.
  2. Sound the horn and continue at speed
  3. Assume the junction is a yield junction and continue
  4. Proceed without stopping because the sign is not fully visible

Explanation

Where a stop sign is present but obscured, the driver must still comply with it by stopping and checking that the way is clear. Visibility problems do not remove the legal obligation.
