Question 1Traffic laws, road signs and signals

On a typical Omani highway outside built-up areas, what is the maximum speed limit for a heavy vehicle unless a lower limit is posted?

  1. 120 km/h
  2. 100 km/h
  3. 80 km/h Correct answer.
  4. 60 km/h

Explanation

Heavy vehicles in Oman are generally restricted to a lower maximum speed than light vehicles on open roads, commonly 80 km/h unless a sign shows a lower figure. Drivers must always obey the posted limit, which may reduce the speed further on dangerous sections. Knowing the default limit for your vehicle class prevents both speeding fines and unsafe braking distances.

Question 2Traffic laws, road signs and signals

A red circular sign with a white horizontal bar across the middle means:

  1. No entry for any vehicle Correct answer.
  2. No overtaking
  3. End of speed restriction
  4. Stop and give way

Explanation

The red circle with a white horizontal bar is the universal no-entry sign, meaning vehicles must not proceed past it. It is often placed at the exit of one-way streets or restricted access points. A driver who ignores it is committing a serious traffic offence.

Question 3Traffic laws, road signs and signals

When a traffic police officer gives hand signals that conflict with the traffic lights, which instruction should you follow?

  1. The vehicle in front
  2. The officer's signals Correct answer.
  3. The road markings
  4. The traffic lights

Explanation

A police officer directing traffic overrides both signals and markings, because the officer can see conditions the automatic system cannot. Drivers must stop, proceed, or wait exactly as the officer indicates. Following the light instead can cause a collision at an intersection under manual control.

Question 4Traffic laws, road signs and signals

What does a broken white line in the centre of a two-way road indicate?

  1. Overtaking is prohibited at all times
  2. Overtaking is permitted when it is safe Correct answer.
  3. Parking is allowed on the line
  4. The road is one-way

Explanation

A broken centre line means the driver may cross it to overtake or turn, provided the manoeuvre is safe and visibility is adequate. It is not an automatic right of way. The driver must still check mirrors, signal, and ensure no oncoming traffic is close.

Question 5Traffic laws, road signs and signals

At an unmarked T-junction in a built-up area, which vehicle has priority?

  1. The vehicle on the minor arm joining the road
  2. The largest vehicle
  3. The vehicle turning right
  4. The vehicle on the main through road Correct answer.

Explanation

Where no signs or markings give priority, traffic on the continuing through road has the right of way over vehicles joining from a side arm. A driver emerging from the minor arm must slow, look, and give way. Vehicle size never confers priority.

Question 6Traffic laws, road signs and signals

A triangular sign with a red border showing a black exclamation mark warns of:

  1. A general hazard or danger ahead Correct answer.
  2. A steep hill ahead
  3. A pedestrian crossing ahead
  4. A roundabout ahead

Explanation

The red-bordered triangle with an exclamation mark is a general warning sign used where no specific symbol fits, alerting drivers to an unusual hazard. The driver should reduce speed and be ready to react. Specific hazards such as crossings or roundabouts have their own dedicated symbols.

Question 7Traffic laws, road signs and signals

When are you permitted to use a mobile phone while driving a heavy vehicle?

  1. When the call lasts under one minute
  2. When using a hands-free kit only
  3. Never while the vehicle is in motion Correct answer.
  4. When traffic is moving slowly

Explanation

Using a hand-held phone while driving is prohibited in Oman, and the safest and legally compliant practice is not to use any phone while the vehicle is moving. Even a hands-free conversation distracts the driver of a heavy vehicle with long stopping distances. If a call is essential, the driver must stop in a safe, legal place first.

Question 8Traffic laws, road signs and signals

What is the purpose of the seat belt requirement for the driver of a heavy goods vehicle?

  1. It is optional if the cab has airbags
  2. It replaces the need for a headrest
  3. It reduces injury risk in a sudden stop or collision Correct answer.
  4. It is required only on motorways

Explanation

Seat belts restrain the occupant and prevent being thrown against the cab interior or through the windscreen during heavy braking or a crash. The law requires the driver and passengers to wear them in vehicles so equipped. Airbags supplement, but never replace, the seat belt.

Question 9Traffic laws, road signs and signals

You approach a roundabout and intend to take the third exit. Which lane should you normally use on a multi-lane approach?

  1. The right lane or a lane marked for that exit Correct answer.
  2. The left lane
  3. Any lane, because priority is automatic
  4. The hard shoulder

Explanation

On a multi-lane roundabout approach, drivers taking an exit beyond the first or second generally use the right-hand lane or a lane marked for that destination. Lane markings on the approach indicate the permitted movements. Choosing the correct lane early avoids cutting across other traffic inside the roundabout.

Question 10Traffic laws, road signs and signals

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

  1. Give way only to heavy vehicles
  2. Stop inside the box until the light turns green
  3. Enter only if the exit is clear Correct answer.
  4. Sound the horn before entering

Explanation

A yellow box junction is designed to keep the crossing clear; a driver may enter only when the exit road is clear enough to leave the box without stopping. Waiting inside the box blocks cross traffic and is an offence. The rule applies even when the light ahead is green if traffic is queued beyond the box.

Question 11Traffic laws, road signs and signals

A heavy vehicle's load overhangs the rear of the vehicle. What is the driver's main obligation?

  1. Drive only at night
  2. Mark the overhang clearly so other road users can see it Correct answer.
  3. Ignore it if the journey is short
  4. Reduce the load by half

Explanation

An overhanging load must be made visible, typically with a warning marker or flag by day and reflective material or a light at night, so following drivers can judge the vehicle's true length. The load must also be securely fastened. Failure to mark an overhang creates a serious collision risk.

Question 12Traffic laws, road signs and signals

When may a heavy vehicle driver sound the horn?

  1. To hurry a slow vehicle ahead
  2. To warn of immediate danger Correct answer.
  3. To signal at every junction
  4. To greet another driver

Explanation

The horn is a warning device to be used when there is a risk of collision or to alert others to your presence in a dangerous situation. Using it to express impatience or to greet others is improper and can be penalised. Excessive or unnecessary horn use distracts other road users.

Question 13Traffic laws, road signs and signals

You are driving a laden heavy vehicle down a long steep gradient. What is the safest technique?

  1. Coast in neutral to save fuel
  2. Hold the footbrake continuously
  3. Select a low gear and use engine braking, applying the brakes in short intervals Correct answer.
  4. Rely on the handbrake

Explanation

On a long descent, a low gear uses engine braking to control speed and prevents the service brakes from overheating and fading. The brakes should be applied in short, firm intervals rather than held continuously. Coasting in neutral removes engine braking and is dangerous in a heavy vehicle.

Question 14Traffic laws, road signs and signals

What is the correct action when an emergency vehicle approaches with flashing lights and siren while you are in a queue?

  1. Move aside safely to let it pass Correct answer.
  2. Sound your horn to warn others
  3. Stop immediately in the lane
  4. Speed up to stay ahead

Explanation

Drivers should make way for emergency vehicles by moving to the side of the road when it is safe to do so, without blocking junctions or endangering pedestrians. Stopping abruptly in the lane can cause a rear-end collision. The aim is to clear a path predictably.

Question 15Traffic laws, road signs and signals

A solid continuous white line separates your lane from the opposite direction. What does it mean?

  1. It marks a parking zone
  2. You may cross it only at night
  3. You must not cross or straddle it Correct answer.
  4. You may cross it to overtake if the road is clear

Explanation

A continuous line must not be crossed or straddled, because it marks a section where overtaking or lane changing is unsafe, often due to limited visibility. Drivers must wait until the line becomes broken before overtaking. Crossing it is a traffic offence.

Question 16Traffic laws, road signs and signals

At a level crossing with a red flashing light and a lowered barrier, what must you do?

  1. Proceed slowly under the barrier
  2. Drive around the barrier if no train is visible
  3. Stop and wait until the lights stop and the barrier lifts Correct answer.
  4. Sound the horn and continue

Explanation

A red flashing signal or lowered barrier means a train is approaching and the crossing must not be entered. Drivers must stop and wait until the signals stop and the barrier is fully raised. Attempting to pass is extremely dangerous because trains cannot stop quickly.

Question 17Traffic laws, road signs and signals

What does a blue circular sign with a white arrow pointing straight ahead mean?

  1. A warning of a bend ahead
  2. A parking area ahead
  3. A prohibition on straight travel
  4. A mandatory direction of travel Correct answer.

Explanation

Blue circular signs give mandatory instructions, and the white arrow shows the direction traffic must take. The driver is required to follow the arrow and may not turn contrary to it. Prohibitions are shown on red circular signs, not blue ones.

Question 18Traffic laws, road signs and signals

A driver of a heavy vehicle is overtaking a cyclist on a narrow road. What minimum clearance should be given where possible?

  1. Half a metre
  2. As close as possible to save space
  3. No gap is needed if you sound the horn
  4. A generous lateral gap of at least about 1.5 metres Correct answer.

Explanation

When overtaking a cyclist, a heavy vehicle should leave a wide lateral gap, generally at least about 1.5 metres where the road permits, because the cyclist may need to swerve for potholes or wind. Passing too close creates turbulence and can knock the rider off. If the gap cannot be given, the driver should wait.

Question 19Traffic laws, road signs and signals

When may you drive a heavy vehicle in a lane marked with a bus symbol?

  1. If you are carrying passengers
  2. At night only
  3. Whenever the general lane is congested
  4. Only if you are a bus or the sign permits your vehicle Correct answer.

Explanation

A lane marked with a bus symbol is reserved for buses, and other vehicles may use it only where a sign or marking expressly allows them. Heavy goods vehicles are generally excluded to keep bus routes clear. Entering a reserved lane without permission is an offence.

Question 20Traffic laws, road signs and signals

What is the correct response when your vehicle begins to aquaplane on a wet road?

  1. Ease off the accelerator and hold the steering steady Correct answer.
  2. Brake hard and steer sharply
  3. Accelerate to regain grip
  4. Pull the handbrake

Explanation

Aquaplaning occurs when water lifts the tyres off the road, so sudden braking or steering can cause a skid. The driver should ease off the accelerator and keep the steering steady until the tyres regain contact. Heavy vehicles are especially prone because of their mass and tyre loading.

Question 21Traffic laws, road signs and signals

A load of loose sand is being carried in an open tipper. What is the driver's responsibility before setting off?

  1. Cover or secure the load so it cannot spill onto the road Correct answer.
  2. Spill a little sand to test the tailgate
  3. Ask a passenger to watch the load
  4. Drive slowly so spillage does not matter

Explanation

Loose material must be covered or otherwise secured so that it cannot blow or fall onto the road, where it can cause skids or hit following vehicles. The tailgate must be properly closed and the load not exceed the permitted weight. Spillage is an offence and a serious hazard.

Question 22Traffic laws, road signs and signals

You are approaching a junction where the traffic light is green but the exit beyond the junction is blocked by queued traffic. What should you do?

  1. Stay behind the stop line until the exit clears Correct answer.
  2. Sound the horn until traffic moves
  3. Use the opposing lane to pass the queue
  4. Enter the junction and wait in the middle

Explanation

Even on a green light, a driver should not enter a junction if the exit is blocked, because stopping in the junction obstructs cross traffic and pedestrians. Waiting behind the stop line keeps the junction clear and is the safe, lawful choice. Entering and blocking the box is an offence.

Question 23Traffic laws, road signs and signals

In Oman, what is the general rule for giving way to pedestrians at a marked crossing?

  1. Vehicles should slow and give way to pedestrians on the crossing Correct answer.
  2. Pedestrians may only cross at night
  3. Pedestrians must always wait for vehicles
  4. Vehicles have priority if they sound the horn

Explanation

At a marked pedestrian crossing, drivers should reduce speed and give way to pedestrians who are on or about to use the crossing. A heavy vehicle needs a long stopping distance, so early braking is essential. Failing to give way endangers the most vulnerable road users.

Question 24Traffic laws, road signs and signals

A heavy vehicle's tyres show deep cuts and exposed cords. What is the correct course of action?

  1. Replace the tyre before use Correct answer.
  2. Reduce speed to 40 km/h
  3. Continue if the vehicle is not fully loaded
  4. Inflate the tyre to maximum pressure

Explanation

A tyre with cuts deep enough to expose the cords is structurally unsafe and can fail under load, especially on a heavy vehicle. It must be replaced before the vehicle is used on the road. Continuing to drive risks a blowout and loss of control.

Question 25Traffic laws, road signs and signals

Why does a heavy vehicle need a much longer stopping distance than a car at the same speed?

  1. Its headlights are dimmer
  2. Its driver reaction time is always longer
  3. Its tyres have less grip by design
  4. Its mass increases the kinetic energy that the brakes must absorb Correct answer.

Explanation

Kinetic energy rises with mass, so a heavy vehicle carries far more energy that the brakes must dissipate to stop, extending the stopping distance. The driver must therefore maintain a larger following gap and anticipate hazards earlier. Reaction time and headlights do not explain the difference.

Question 26Traffic laws, road signs and signals

A heavy vehicle driver approaches a steady red traffic light at a junction. What must the driver do?

  1. Slow down and proceed if the junction appears clear.
  2. Stop before the stop line and wait until the light turns green. Correct answer.
  3. Stop only if another vehicle is approaching from the right.
  4. Sound the horn and continue through the junction.

Explanation

A steady red light requires a complete stop before the stop line or crossing. The driver must remain stopped until a green light or a lawful signal from a police officer permits movement, regardless of whether traffic is visible.

Question 27Traffic laws, road signs and signals

On a two-way road, you see a broken white line along the centre. What does this marking allow?

  1. Stopping in the lane to load or unload goods.
  2. Driving on the wrong side of the road at any time.
  3. Parking on the carriageway during daylight hours.
  4. Overtaking when it is safe and the road ahead is clear. Correct answer.

Explanation

A broken white centre line indicates that lane crossing is permitted, so overtaking is allowed when visibility and traffic conditions make it safe. The line does not create a parking or stopping right, and it does not authorise driving on the wrong side.

Question 28Traffic laws, road signs and signals

You are driving a heavy vehicle and approach a junction where a traffic officer is directing traffic with arm signals. The traffic light shows green. What should you do?

  1. Stop and wait for the light to turn red before moving.
  2. Proceed only after sounding the horn to warn the officer.
  3. Obey the green light and ignore the officer.
  4. Follow the officer's signals even though the light is green. Correct answer.

Explanation

Directions given by a police officer or authorised traffic controller take precedence over traffic lights and signs. When an officer is controlling a junction, drivers must obey the officer's signals even if the light shows green.

Question 29Traffic laws, road signs and signals

A heavy goods vehicle approaches a sign showing a red circle with a white horizontal bar. What does this sign require?

  1. No entry for all vehicles. Correct answer.
  2. No overtaking for heavy vehicles.
  3. No parking during peak hours.
  4. No stopping at any time.

Explanation

The red circle with a white horizontal bar is the international regulatory sign for no entry. It prohibits all vehicles from entering the road or area beyond the sign, and a heavy vehicle driver must not proceed past it.

Question 30Traffic laws, road signs and signals

A heavy vehicle is travelling on a road with a posted speed limit of 80 km/h. The driver sees a sign showing a red circle with the number 60. What is the maximum permitted speed?

  1. 60 km/h, because the sign imposes a lower limit. Correct answer.
  2. 100 km/h, because heavy vehicles may exceed the general limit.
  3. 60 km/h only when towing a trailer.
  4. 80 km/h, because the general limit still applies.

Explanation

A red circular sign with a number sets a maximum speed limit for that section of road. Where a lower limit is posted, it replaces the general limit, so the driver must not exceed 60 km/h even though the general limit is 80 km/h.

Question 31Road markings, lane discipline and junctions

On a two-way Omani road, a single broken white line runs down the centre. What does it mean for a heavy vehicle driver?

  1. The driver must stay in the left lane and never cross it
  2. The lane is reserved for buses and taxis only
  3. Overtaking is allowed when the road is clear and safe Correct answer.
  4. Overtaking is prohibited for all vehicles at all times

Explanation

A single broken white centre line marks the boundary between opposing traffic flows and permits a driver to cross it to overtake when visibility and traffic conditions make the manoeuvre safe. For a heavy vehicle the manoeuvre must also be realistic given its size, weight and stopping distance.

Question 32Road markings, lane discipline and junctions

You are driving a loaded truck and see a continuous white line on your side of the centre of the road. What is the correct action?

  1. Cross it briefly if the vehicle ahead is slow-moving
  2. Sound the horn and cross it if the road ahead looks clear
  3. Cross it only at night when traffic is light
  4. Keep to your side and do not cross the line to overtake Correct answer.

Explanation

A continuous line on your side means crossing or straddling it is prohibited, usually because visibility or the road layout makes overtaking dangerous. A heavy vehicle must wait behind the slower vehicle until the marking changes or a safe opportunity appears.

Question 33Road markings, lane discipline and junctions

What is the purpose of a double continuous white line along the centre of a road?

  1. To show where parking is permitted outside peak hours
  2. To indicate a lane that only heavy goods vehicles may use
  3. To separate traffic moving in opposite directions where crossing is prohibited for both flows Correct answer.
  4. To mark the edge of the carriageway next to the hard shoulder

Explanation

Double continuous lines divide opposing traffic streams and forbid crossing from either direction, typically on bends, crests or narrow sections where overtaking would be unsafe. For a long or heavy vehicle the restriction is especially important because the manoeuvre takes more time and distance.

Question 34Road markings, lane discipline and junctions

A broken white line separates two lanes travelling in the same direction on a dual carriageway. What does this marking allow?

  1. Using the right-hand lane as a permanent overtaking lane
  2. Changing lanes when it is safe to do so Correct answer.
  3. Stopping in the lane to load or unload goods
  4. Remaining in the lane for the whole journey regardless of speed

Explanation

A broken white line between lanes moving in the same direction permits lane changes provided the driver checks mirrors, signals and blind spots and there is a safe gap. A heavy vehicle needs a larger gap and more time to complete the move.

Question 35Road markings, lane discipline and junctions

You are approaching a junction where a broken white line crosses the mouth of the side road. What does this line indicate to a driver emerging from the side road?

  1. Accelerate to merge ahead of approaching main-road traffic
  2. Give way to traffic on the main road before entering or crossing it Correct answer.
  3. Proceed without checking because the main road must yield
  4. Stop completely and wait for a green signal before moving

Explanation

A broken line across a side-road mouth is a give-way line, requiring the emerging driver to yield to traffic already on the main road. It differs from a solid stop line, which requires a complete stop before proceeding.

Question 36Road markings, lane discipline and junctions

What does a solid white line across your lane at a traffic signal or stop sign require?

  1. A complete stop before the line Correct answer.
  2. A check of mirrors without stopping
  3. A reduction of speed only if traffic is present
  4. A lane change to the right before the junction

Explanation

A solid stop line marks the point where a vehicle must come to a complete halt when a stop is required by the signal, sign or a police officer. Stopping beyond the line can obstruct pedestrians and crossing traffic.

Question 37Road markings, lane discipline and junctions

A yellow box junction marking is painted at an intersection. How should a heavy vehicle driver treat it?

  1. Enter and wait inside the box until the traffic ahead moves
  2. Treat it as a parking area while waiting for a load
  3. Use it to change lanes across the junction
  4. Enter only if the exit is clear so the vehicle does not stop inside the box Correct answer.

Explanation

A yellow box marks an area that must be kept clear of stationary traffic, so a driver should enter only when the exit beyond it is free. A long vehicle that stops inside the box can block crossing traffic and pedestrians.

Question 38Road markings, lane discipline and junctions

On a multi-lane road, a heavy vehicle is travelling slowly in the left-hand lane while faster traffic passes on the right. What does lane discipline require?

  1. Straddle two lanes so other drivers can see the vehicle clearly
  2. Stay in the left-hand lane unless overtaking is necessary Correct answer.
  3. Move to the right-hand lane to let others overtake on the left
  4. Use the hard shoulder to let faster traffic pass

Explanation

In Oman traffic keeps to the right, so the left-hand lane is the normal travelling lane and slower vehicles should stay there unless they need to overtake. Remaining in the correct lane keeps faster traffic flowing and reduces conflict.

Question 39Road markings, lane discipline and junctions

A driver on a dual carriageway has just overtaken a slower truck and the lane to the right is now clear for a long distance. What should the driver do?

  1. Move to the left-hand lane and stay there permanently
  2. Remain in the left-hand lane because it is now empty
  3. Return to the right-hand lane once it is safe Correct answer.
  4. Reduce speed until another vehicle follows

Explanation

After completing an overtake, a driver should return to the normal travelling lane on the right as soon as it is safe, leaving the left-hand lane free for overtaking. Holding the left lane unnecessarily disrupts traffic flow.

Question 40Road markings, lane discipline and junctions

You are driving a long articulated vehicle and need to turn left at a tight urban junction. How should you position the vehicle before the turn?

  1. Stop before the junction and reverse into the side road
  2. Keep as close to the left kerb as possible throughout the turn
  3. Approach in the right-hand lane and cut across the junction
  4. Approach slightly towards the centre of the road to allow the rear wheels to clear the kerb Correct answer.

Explanation

A long vehicle's rear wheels track inside the front wheels, so a driver may need to swing out slightly before a tight turn to stop the trailer mounting the kerb or striking street furniture. The manoeuvre must be done without endangering other road users.

Question 41Road markings, lane discipline and junctions

What does a hatched area bordered by a continuous white line in the centre of the road mean for a heavy vehicle driver?

  1. The area may be used for overtaking when traffic is light
  2. The area is closed to traffic and must not be entered except in an emergency Correct answer.
  3. The area is a designated loading bay for goods vehicles
  4. The area marks where a vehicle may stop to check directions

Explanation

Hatching bounded by a continuous line marks an area that traffic must keep out of, often protecting turning space or separating opposing flows. Entering it can put a vehicle in conflict with traffic emerging from a junction.

Question 42Road markings, lane discipline and junctions

A heavy vehicle approaches a roundabout where the lane markings show a broken line between the approach lanes. What is the correct lane discipline?

  1. Select the lane matching the intended exit and change only where the broken line permits Correct answer.
  2. Ignore the markings and follow the vehicle ahead
  3. Cross the broken line at any point without checking mirrors
  4. Stay in the left-hand lane for every exit to avoid lane changes

Explanation

Broken lines between approach lanes allow a driver to change lane when safe, so the correct approach is to select the lane for the intended exit and move across only where permitted. A heavy vehicle should plan early because lane changes take more space.

Question 43Road markings, lane discipline and junctions

What is indicated by a lane marked with a bicycle symbol and a solid white boundary line on an urban road?

  1. A lane where heavy vehicles may park to unload
  2. A lane that all vehicles may use when traffic is heavy
  3. A lane reserved for cyclists that other vehicles must not enter Correct answer.
  4. A lane reserved for buses during peak hours

Explanation

A cycle lane marked with a bicycle symbol and bounded by a solid line is reserved for cyclists, and other vehicles must keep out of it. A heavy vehicle should check for cyclists in this lane before turning across it.

Question 44Road markings, lane discipline and junctions

You are driving a truck and the lane ahead narrows because of roadworks marked by cones and a hatched area. What is the safest response?

  1. Stop in the closed lane and wait for the works to finish
  2. Drive over the hatched area to keep your lane position
  3. Maintain speed and force a gap in the adjacent lane
  4. Reduce speed early and merge into the open lane where the markings allow Correct answer.

Explanation

When lane markings and cones show a lane closing, a heavy vehicle should slow early and merge where permitted, giving other drivers time to react. Maintaining speed and forcing a gap risks a collision with a vehicle already in the open lane.

Question 45Road markings, lane discipline and junctions

At a T-junction where your road ends and meets a through road, what marking should you expect and what does it require?

  1. A broken centre line allowing you to enter without yielding
  2. A box junction requiring you to stop inside the junction
  3. A give-way line or stop line requiring you to yield to traffic on the through road Correct answer.
  4. A hatched area allowing you to wait in the middle of the through road

Explanation

Where a road ends at a T-junction, the entering driver must yield to traffic on the through road, shown by a give-way or stop line across the mouth. A heavy vehicle needs a generous gap because it accelerates slowly.

Question 46Road markings, lane discipline and junctions

A driver needs to turn right at a junction and there is a central refuge with a hatched area bordered by broken lines. How may the hatched area be used?

  1. It may be used to park while waiting for a gap in traffic
  2. It may be entered when necessary to complete the turn, provided it is safe Correct answer.
  3. It may be used to overtake slower vehicles on the right
  4. It may never be entered under any circumstances

Explanation

Hatching with a broken border may be entered when it is necessary, for example to position for a right turn, as long as it is safe and does not obstruct other traffic. A continuous border, by contrast, prohibits entry.

Question 47Road markings, lane discipline and junctions

Why does a loaded heavy vehicle need to begin braking earlier when approaching a junction controlled by a stop line?

  1. Its brakes are designed to work only at low speed
  2. Its tyres have less grip on dry asphalt than car tyres
  3. Its greater mass and load increase stopping distance compared with a car Correct answer.
  4. Junction markings require heavy vehicles to stop twice

Explanation

A loaded heavy vehicle carries far more momentum than a car, so the distance needed to stop from the same speed is considerably greater. Anticipating the stop line and braking early keeps the vehicle from overshooting into the junction.

Question 48Road markings, lane discipline and junctions

A driver in the left-hand lane of a three-lane road intends to exit right at the next junction. What is the best lane-discipline plan?

  1. Move right early, one lane at a time, checking mirrors and signalling each change Correct answer.
  2. Wait until the junction and cut across all lanes at once
  3. Stay in the left lane and exit from there regardless of markings
  4. Use the hard shoulder to reach the exit ahead of traffic

Explanation

Planning ahead and changing lane one at a time with proper observation and signalling gives other drivers time to react and keeps the heavy vehicle out of conflict with faster traffic. A single sweeping movement across several lanes is unpredictable and dangerous.

Question 49Road markings, lane discipline and junctions

At a signalised junction the stop line is worn and partly obscured. What should a heavy vehicle driver do?

  1. Stop in the pedestrian crossing area to shorten the wait
  2. Stop at the position the line would occupy, keeping the crossing clear Correct answer.
  3. Stop well past the signal pole to be visible
  4. Ignore the stop line and proceed if the signal is amber

Explanation

Even when a stop line is worn, the driver must stop where the line is positioned so the pedestrian crossing and junction remain clear. Stopping beyond it can block pedestrians and crossing traffic.

Question 50Road markings, lane discipline and junctions

A truck driver is following a car on a road with a broken centre line and a clear view ahead. What must the driver confirm before overtaking?

  1. That the car ahead is travelling below the speed limit
  2. That the road behind is empty for at least one kilometre
  3. That the overtaking manoeuvre can be completed before any hazard and within the permitted markings Correct answer.
  4. That the horn has been sounded twice

Explanation

Before overtaking, a heavy vehicle driver must be sure the manoeuvre can be completed safely within the distance available and that no marking or hazard forbids it. The size and acceleration of the vehicle make a conservative judgment essential.
