Question 1Rules of the Road (road signage, road markings, traffic rules and regulations)

On an Irish motorway, what does a broken white line along the centre of the carriageway normally indicate?

  1. The edge of the hard shoulder, which must never be crossed
  2. A mandatory stop line before a toll plaza
  3. A bus lane boundary that only buses may cross
  4. Lane markings that may be crossed when it is safe to change lane Correct answer.

Explanation

Broken white centre lines on a motorway separate lanes and may be crossed when it is safe and necessary to change lane or overtake. They are advisory lane divisions rather than prohibitions. The hard shoulder edge is marked by a continuous yellow line, not a broken white one.

Question 2Rules of the Road (road signage, road markings, traffic rules and regulations)

What is the general default speed limit on Irish national roads outside built-up areas, unless signs show otherwise?

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

Explanation

The default speed limit on national secondary and ordinary national roads outside built-up areas is 80 km/h, unless a different limit is signposted. Motorways and some dual carriageways carry higher default limits. Drivers must always obey posted signs where they differ.

Question 3Rules of the Road (road signage, road markings, traffic rules and regulations)

You approach a junction controlled by traffic lights showing a flashing amber light. What must you do?

  1. Proceed only if the way is clear, giving way to pedestrians and traffic on the priority road Correct answer.
  2. Stop completely and wait for a green light before moving
  3. Treat it as a red light and remain stopped until it changes
  4. Sound the horn and proceed with priority over crossing traffic

Explanation

A flashing amber signal means you may proceed with caution, but you must yield to pedestrians on or entering the crossing and to traffic on the road you are joining. It is not a stop signal in the way a red light is. Proceeding cautiously and yielding is the correct response.

Question 4Rules of the Road (road signage, road markings, traffic rules and regulations)

What does a single continuous white line along the centre of a two-way road mean?

  1. You may cross it freely to overtake slower vehicles
  2. It marks the boundary of a cycle lane
  3. It indicates a one-way street
  4. You must not cross it to overtake, except to avoid an obstruction Correct answer.

Explanation

A single continuous white centre line prohibits crossing to overtake, though you may cross it in limited circumstances such as passing a stationary obstruction or turning into a premises when safe. It is a restriction, not an absolute ban in every situation. Ordinary overtaking across it is not permitted.

Question 5Rules of the Road (road signage, road markings, traffic rules and regulations)

At a standard Irish roundabout with no traffic lights, who has priority?

  1. The largest vehicle approaching
  2. Traffic entering from the left
  3. Traffic entering from the right
  4. Traffic already on the roundabout Correct answer.

Explanation

At a roundabout you must yield to traffic already circulating on the roundabout before you enter. Traffic approaching from the right is not automatically entitled to priority, and vehicle size gives no right of way. You should enter only when there is a safe gap.

Question 6Rules of the Road (road signage, road markings, traffic rules and regulations)

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

  1. To use the box only for loading and unloading
  2. To stop inside the box until the lights change
  3. To give way to traffic entering the box from side roads
  4. Not to enter the box unless the exit is clear, except when turning right and blocked only by oncoming traffic Correct answer.

Explanation

A yellow box junction must not be entered unless your exit is clear, so you do not block the junction. The exception is when you are turning right and are prevented only by oncoming traffic. Stopping inside the box otherwise is an offence.

Question 7Rules of the Road (road signage, road markings, traffic rules and regulations)

What shape and colour is an Irish regulatory sign that prohibits an action, such as a no-entry sign?

  1. A green rectangle with white text
  2. A blue rectangle with white text
  3. A yellow diamond with black symbols
  4. A red circle, usually with a white background Correct answer.

Explanation

Prohibitory and restrictive regulatory signs in Ireland are circular with a red border, typically on a white background. Blue rectangles are generally information or mandatory direction signs. Yellow diamonds are warning signs, and green rectangles indicate directions on national routes.

Question 8Rules of the Road (road signage, road markings, traffic rules and regulations)

When may you use the hard shoulder of a motorway?

  1. In an emergency or breakdown, or where signs specifically permit it at certain times Correct answer.
  2. Whenever you want to overtake slow traffic
  3. For short rest stops at any time
  4. When the carriageway is busy and lanes are congested

Explanation

The hard shoulder is for emergencies and breakdowns, or for use as a running lane only where signs explicitly permit it at designated times. It must not be used for overtaking, resting, or avoiding congestion. Using it otherwise is dangerous and an offence.

Question 9Rules of the Road (road signage, road markings, traffic rules and regulations)

You are driving a truck and see a sign showing a red circle containing the number 30 with a red diagonal line through it. What does this indicate?

  1. A prohibition on vehicles over 30 feet
  2. The end of a 30 km/h speed restriction Correct answer.
  3. A minimum speed of 30 km/h
  4. A weight limit of 30 tonnes

Explanation

A red circle with a number and a diagonal slash marks the end of the restriction shown, so this indicates the end of a 30 km/h speed limit. A plain red circle with a number sets the limit, while a blue circle with a number sets a minimum speed. Weight limits use a tonne figure without a speed context.

Question 10Rules of the Road (road signage, road markings, traffic rules and regulations)

On a two-way road, when may you cross a double continuous white line?

  1. Whenever the road ahead is clear of oncoming traffic
  2. Only in limited circumstances such as accessing a premises or passing a stationary obstruction, when safe Correct answer.
  3. Only if you are driving a goods vehicle
  4. Never, under any circumstances

Explanation

Double continuous white lines are the strictest centre-line marking and must not be crossed for overtaking. Crossing is allowed only in limited situations, for example to enter a premises or pass a stationary obstruction, and only when it is safe. Blanket statements that it is always forbidden are inaccurate.

Question 11Rules of the Road (road signage, road markings, traffic rules and regulations)

A truck approaches a junction where a garda is directing traffic with arms outstretched horizontally. The traffic lights show green. What should the driver do?

  1. Stop, because a garda's signals override the traffic lights Correct answer.
  2. Proceed, because the green light gives priority
  3. Sound the horn and continue slowly
  4. Proceed only if no other vehicle is moving

Explanation

Directions given by a garda on point duty take precedence over traffic lights and signs. Arms outstretched horizontally generally means traffic must stop. The driver must obey the garda even though the light is green.

Question 12Rules of the Road (road signage, road markings, traffic rules and regulations)

What is the meaning of a broken yellow line along the edge of the carriageway on a rural road?

  1. It marks the edge of the carriageway, with the broken format indicating a hard shoulder that may be used only in limited circumstances Correct answer.
  2. It indicates a no-parking zone at all times
  3. It shows the boundary of a school warden crossing area
  4. It marks a bus lane

Explanation

A broken yellow line marks the edge of the carriageway and indicates a hard shoulder, which in normal driving should not be used as a running lane. A continuous yellow line at the edge means no parking or stopping. The broken format distinguishes the shoulder edge from a parking restriction.

Question 13Rules of the Road (road signage, road markings, traffic rules and regulations)

You are driving a heavy goods vehicle on a road with a sign showing a red circle containing '3.5t' with a goods vehicle symbol. What does it mean?

  1. Goods vehicles over 3.5 tonnes are prohibited from the road Correct answer.
  2. Goods vehicles must keep 3.5 metres apart
  3. A weight restriction applies only during daylight hours
  4. The maximum permitted speed for goods vehicles is 3.5 km/h

Explanation

A red circle containing a weight figure and a goods vehicle symbol prohibits goods vehicles exceeding that weight from using the road. The restriction is continuous unless a supplementary plate states otherwise. It is not a speed or spacing instruction.

Question 14Rules of the Road (road signage, road markings, traffic rules and regulations)

At a pelican crossing, what does the flashing amber light mean for a truck driver?

  1. Give way to pedestrians still on the crossing, and proceed only when it is clear Correct answer.
  2. Proceed immediately, as pedestrians must wait
  3. Stop and remain stopped until the light turns green
  4. Reverse away from the crossing to give more room

Explanation

At a pelican crossing the flashing amber phase means drivers must yield to any pedestrians still crossing and may proceed once the crossing is clear. It is not the same as a red light. Reversing near a crossing is dangerous and prohibited.

Question 15Rules of the Road (road signage, road markings, traffic rules and regulations)

What does a supplementary plate showing times beneath a parking restriction sign indicate?

  1. The restriction applies at all times except those shown
  2. The times indicate when loading is compulsory
  3. The restriction applies only during the times shown Correct answer.
  4. The times show when the road is closed to all traffic

Explanation

A supplementary plate with times under a parking or stopping restriction specifies the period during which the restriction operates. Outside those times the restriction does not apply unless another plate states otherwise. It does not create loading obligations or road closures.

Question 16Rules of the Road (road signage, road markings, traffic rules and regulations)

On a motorway, you intend to leave at the next exit. When should you move into the left lane?

  1. At the last moment to avoid holding up traffic behind
  2. By crossing the hatched area at the exit
  3. Only after passing the exit sign at the slip road
  4. In good time before the exit, after checking mirrors and signalling Correct answer.

Explanation

You should plan ahead, check mirrors, signal, and move into the left lane in good time before your exit. Late lane changes are dangerous and may cause collisions. Hatched areas and chevron markings must not be crossed.

Question 17Rules of the Road (road signage, road markings, traffic rules and regulations)

What is the correct action when you see a stop sign at a junction with a solid white stop line?

  1. Come to a complete stop at the line and proceed only when safe Correct answer.
  2. Stop beyond the line to improve visibility
  3. Stop only if another vehicle is approaching
  4. Slow down and proceed if the road looks clear

Explanation

A stop sign requires a complete stop at the stop line, regardless of whether traffic appears clear. You then proceed only when it is safe. Rolling slowly through or stopping beyond the line does not satisfy the requirement.

Question 18Rules of the Road (road signage, road markings, traffic rules and regulations)

A truck driver wishes to overtake a slower vehicle on a single carriageway. Which factor is most important in deciding whether it is safe?

  1. Whether the driver is familiar with the road
  2. The available clear view and distance ahead, plus the road markings and oncoming traffic Correct answer.
  3. The time of day
  4. The size of the vehicle being overtaken

Explanation

Safe overtaking depends on a clear view of the road ahead, sufficient clear distance, and compliance with road markings such as continuous white lines. The size of the other vehicle, familiarity, and time of day are secondary. The decision must be based on observable road conditions.

Question 19Rules of the Road (road signage, road markings, traffic rules and regulations)

A driver sees a broken white line with long marks and short gaps on the left edge of a motorway lane. What is this marking?

  1. A cycle track boundary
  2. A lane line indicating a lane drop or a hazard ahead requiring caution Correct answer.
  3. A pedestrian crossing approach
  4. A bus stop clearway

Explanation

On motorways, broken lines with long marks and short gaps warn of a lane drop or other hazard ahead, prompting drivers to be alert and consider changing lane. They are not pedestrian or cycle markings, which do not appear on motorway carriageways.

Question 20Rules of the Road (road signage, road markings, traffic rules and regulations)

You are driving a truck on a road where a continuous white line on your side is paired with a broken white line on the opposite side. What does this mean?

  1. Neither direction may ever cross
  2. Both directions may cross freely
  3. You must not cross the lines, but oncoming traffic may cross when safe Correct answer.
  4. The lines mark a cycle lane

Explanation

Where a continuous line is paired with a broken line, the restriction applies to the side with the continuous line. Traffic on your side must not cross, while oncoming traffic on the broken side may cross when it is safe. The meaning depends on which line is nearest the driver.

Question 21Rules of the Road (road signage, road markings, traffic rules and regulations)

A truck approaches a junction marked with a hatched area bounded by a continuous white line. How should the driver treat the hatched area?

  1. Stop in it to check directions
  2. Do not enter it except in an emergency, as the continuous boundary prohibits crossing Correct answer.
  3. Use it to queue for the junction when traffic is heavy
  4. Drive through it to shorten the turning path

Explanation

A hatched area bounded by a continuous white line must not be entered except in an emergency. It is designed to separate traffic and protect turning movements. Using it for queuing, shortcuts, or stopping is prohibited.

Question 22Rules of the Road (road signage, road markings, traffic rules and regulations)

What is the significance of a broken white line with very short gaps between the marks, used across a junction approach on a major road?

  1. It warns of a hazard or junction ahead and advises caution Correct answer.
  2. It marks a place where overtaking is compulsory
  3. It grants priority over traffic from side roads
  4. It indicates a toll booth lane

Explanation

Closely spaced broken lines on the approach to a hazard or junction warn drivers to slow down and be prepared. They do not confer priority or require overtaking. Priority at junctions is governed by signs and road layout, not by this marking.

Question 23Rules of the Road (road signage, road markings, traffic rules and regulations)

A driver is on a road with a sign showing a blue circle containing a white bicycle. What does this sign require?

  1. Cyclists must give way to motor traffic
  2. Cyclists are prohibited from the road
  3. A parking area for bicycles
  4. A route or lane reserved for cyclists, which other vehicles must not use Correct answer.

Explanation

A blue circular sign with a bicycle indicates a route or lane reserved for cyclists. Other vehicles must not use it unless signs indicate shared use. It is a mandatory instruction sign, not a prohibition on cyclists.

Question 24Rules of the Road (road signage, road markings, traffic rules and regulations)

On a dual carriageway, what does a broken white line separating the two lanes on your side of the central reservation mean for a truck driver?

  1. Lanes may be changed when safe, but the central reservation must never be crossed Correct answer.
  2. The right-hand lane is reserved for overtaking only and must be left empty at all times
  3. The lines mark the edge of the carriageway
  4. The left-hand lane is for slow vehicles only and may not be used to overtake

Explanation

Broken white lines between lanes on the same side of a dual carriageway permit lane changes when safe. The central reservation, marked separately, must never be crossed. Lane use is governed by general rules rather than an absolute ban on occupying a lane.

Question 25Rules of the Road (road signage, road markings, traffic rules and regulations)

What does a supplementary plate reading 'Except for access' beneath a prohibition sign mean?

  1. The prohibition applies only to vehicles with no passengers
  2. The prohibition applies to all vehicles without exception
  3. The prohibition does not apply to vehicles needing to enter premises or property on that road Correct answer.
  4. The prohibition applies only outside business hours

Explanation

'Except for access' allows vehicles that need to reach premises or property on the restricted road to enter, while through traffic remains prohibited. It is a common exemption wording on weight and traffic regulation signs. It does not refer to passengers or time of day.

Question 26Rules of the Road (road signage, road markings, traffic rules and regulations)

A truck is travelling on a national road and passes a circular sign with a blue background and a white arrow pointing diagonally down-left. What does this sign tell the driver?

  1. Keep left of the traffic island or obstruction ahead Correct answer.
  2. Give way to traffic approaching from the left
  3. Turn left at the next junction only
  4. The left lane is closed to goods vehicles

Explanation

Blue circular signs are mandatory instruction signs, and a white arrow angled down to the left directs traffic to pass on the left-hand side of an obstruction or traffic island. It is not a direction sign to a destination and does not create a give-way obligation.

Question 27Rules of the Road (road signage, road markings, traffic rules and regulations)

What does a warning sign showing a black symbol of a truck on a red-bordered triangle indicate on an Irish road?

  1. Heavy goods vehicles prohibited ahead
  2. Risk of grounding or a low bridge ahead Correct answer.
  3. A steep ascent ahead
  4. A weighbridge check point ahead

Explanation

Red-bordered triangular signs are warning signs, and the goods vehicle symbol in this context warns of a hazard such as a low bridge or hump where a high or long vehicle may ground. Prohibitions are shown on circular signs, not triangles.

Question 28Rules of the Road (road signage, road markings, traffic rules and regulations)

A truck driver sees a circular sign with a red border containing a black arrow curving to the right with a red diagonal line through it. What does this mean?

  1. Right turn on a green light only
  2. No right turn Correct answer.
  3. Turn right ahead
  4. Right lane for overtaking only

Explanation

A red circle with a diagonal slash is a prohibition sign, so a crossed-out right-turn arrow means turning right is not permitted. The slash is what distinguishes a prohibition from a mandatory direction sign.

Question 29Rules of the Road (road signage, road markings, traffic rules and regulations)

On an Irish road, what does a broken white line painted across the entrance to a side road indicate to a truck driver emerging from it?

  1. A stop line requiring a full stop
  2. A pedestrian crossing boundary
  3. A bus stop clearance marking
  4. A yield or give way line Correct answer.

Explanation

A broken white line across the mouth of a side road is a yield line, meaning the driver must give way to traffic on the road being entered. A stop line is a solid white line and carries a separate stop sign obligation.

Question 30Rules of the Road (road signage, road markings, traffic rules and regulations)

What is the general speed limit for heavy goods vehicles on a national road in Ireland, unless a lower limit is signposted?

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

Explanation

Heavy goods vehicles are subject to a general limit of 80 km/h on national roads, lower than the 100 km/h limit for cars. Drivers must also obey any lower signposted limit on a particular stretch.

Question 31Rules of the Road (road signage, road markings, traffic rules and regulations)

A truck driver approaches a junction controlled by traffic lights showing a green light, but the exit beyond the junction is blocked by stationary traffic. What should the driver do?

  1. Sound the horn and edge through slowly
  2. Proceed into the junction and wait in the box
  3. Mount the footpath to pass the queue
  4. Stop before the junction and wait until the exit is clear Correct answer.

Explanation

A green light does not entitle a driver to enter a junction that cannot be cleared, as doing so blocks the junction and cross traffic. The correct action is to wait behind the stop line until there is room to clear the junction completely.

Question 32Rules of the Road (road signage, road markings, traffic rules and regulations)

What does a yellow line painted along the kerb edge of a road indicate to a truck driver?

  1. Parking or waiting restrictions apply at that location Correct answer.
  2. Overtaking is prohibited along the road
  3. A cycle lane begins at that point
  4. A loading bay is reserved for goods vehicles

Explanation

Yellow lines along the kerb indicate parking and waiting restrictions, with single and double lines representing different durations of restriction. They do not affect the right to drive along the road, only the right to stop or park there.

Question 33Rules of the Road (road signage, road markings, traffic rules and regulations)

What does a rectangular sign with a white background and a black diagonal band across it mean when placed at the end of a restriction?

  1. The restriction begins at this point
  2. A speed camera operates beyond the sign
  3. The road ahead is closed to all traffic
  4. The restriction ends at this point Correct answer.

Explanation

A white rectangular sign crossed by a black diagonal band marks the end of a restriction, such as the end of a speed limit or an overtaking ban. The restriction applies up to the sign and no further.

Question 34Rules of the Road (road signage, road markings, traffic rules and regulations)

A truck driver on a single carriageway intends to turn right into a minor road. What is the correct procedure?

  1. Swing wide to the left first and turn sharply across the oncoming lane
  2. Stop in the left lane and wait for a gap in traffic behind
  3. Turn from the left lane while signalling right continuously
  4. Move to the centre of the road, give way to oncoming traffic and signal before turning Correct answer.

Explanation

A right turn is made from a position just left of the centre line, after signalling and giving way to oncoming traffic and any pedestrians crossing the road being entered. Waiting in the left lane or swinging left first would confuse other road users.

Question 35Rules of the Road (road signage, road markings, traffic rules and regulations)

What is the meaning of a white diamond marking painted on the road surface in the centre of a lane approaching a junction?

  1. A speed limit change takes effect here
  2. A bus lane begins at this point
  3. A yield line is approaching and drivers should prepare to give way Correct answer.
  4. A pedestrian crossing is immediately ahead

Explanation

White diamond markings on the approach to a junction warn that a yield line follows, giving drivers advance notice to slow and prepare to give way. They are common where the yield line may be obscured by traffic or road geometry.

Question 36Rules of the Road (road signage, road markings, traffic rules and regulations)

A truck driver is following a large vehicle on a wet road and cannot see the road ahead past it. What is the safest action?

  1. Flash headlights to ask the vehicle to speed up
  2. Move closer so the vehicle cannot brake suddenly
  3. Drop back to increase the gap and improve forward visibility Correct answer.
  4. Overtake immediately regardless of oncoming traffic

Explanation

Dropping back restores the view of the road ahead and increases the stopping distance available if the vehicle in front brakes. A truck needs a longer gap than a car because of its greater stopping distance, especially on a wet surface.

Question 37Rules of the Road (road signage, road markings, traffic rules and regulations)

What does a sign showing a red circle containing a black motorcycle with a red diagonal line through it prohibit?

  1. Overtaking by motorcycles
  2. Parking by motorcycles
  3. Use of the road by all vehicles
  4. Entry by motorcycles Correct answer.

Explanation

A red circle with a diagonal slash is a prohibition sign, so the crossed-out motorcycle means motorcycles are not permitted beyond the sign. The specific vehicle symbol determines the class of traffic affected.

Question 38Rules of the Road (road signage, road markings, traffic rules and regulations)

A truck driver is entering a roundabout where the road markings show a broken white line across the entry. What obligation does this create?

  1. Stop completely before entering the roundabout
  2. Give way only to vehicles indicating to leave
  3. Give way to traffic already on the roundabout coming from the right Correct answer.
  4. Proceed without yielding as roundabout traffic must stop

Explanation

A broken white line at a roundabout entry is a yield line, requiring the driver to give way to traffic already circulating, which approaches from the right in Ireland. A full stop is only required where a stop line and stop sign are present.

Question 39Rules of the Road (road signage, road markings, traffic rules and regulations)

What does a supplementary plate showing a red-bordered circle with a truck symbol beneath a weight restriction sign commonly clarify?

  1. The restriction applies specifically to goods vehicles over the stated weight Correct answer.
  2. The restriction applies only during daylight hours
  3. The restriction applies only to trailers
  4. The restriction applies only to buses

Explanation

A supplementary plate beneath a regulatory sign refines its scope, and a plate showing a goods vehicle symbol limits the weight restriction to goods vehicles above the stated weight. Other traffic is not affected by that restriction.

Question 40Rules of the Road (road signage, road markings, traffic rules and regulations)

A truck driver approaches a level crossing with a flashing red light signal. What must the driver do?

  1. Proceed slowly while the red lights flash
  2. Sound the horn and cross quickly
  3. Stop and remain stopped until the signals stop flashing and the way is clear Correct answer.
  4. Stop only if a barrier is lowering

Explanation

Flashing red lights at a level crossing mean a train is approaching, and drivers must stop and wait until the signals cease and the crossing is clear. Crossing while the lights flash is extremely dangerous and illegal.

Question 41Rules of the Road (road signage, road markings, traffic rules and regulations)

What does a continuous white line along the left edge of a carriageway separate?

  1. A cycle lane from a bus lane
  2. Two lanes travelling in opposite directions
  3. The carriageway from the hard shoulder or verge Correct answer.
  4. A parking bay from a loading bay

Explanation

The continuous white edge line marks the boundary between the running carriageway and the hard shoulder or verge. It helps drivers, particularly in darkness or poor visibility, keep their vehicle within the carriageway.

Question 42Rules of the Road (road signage, road markings, traffic rules and regulations)

A truck driver towing a trailer on a motorway notices the trailer beginning to snake. What is the correct response?

  1. Ease off the accelerator gently and avoid harsh braking or steering Correct answer.
  2. Brake firmly to straighten the combination
  3. Accelerate to pull the trailer straight
  4. Steer sharply against the sway

Explanation

Easing off the accelerator allows the combination to slow gradually and the trailer to stabilise without inducing further sway. Harsh braking or sharp steering can amplify a snake and cause a jackknife.

Question 43Rules of the Road (road signage, road markings, traffic rules and regulations)

What is the meaning of a sign showing a red circle with the number 30 in black and the word 'km/h' on a supplementary plate?

  1. A speed camera operates 30 metres ahead
  2. A minimum speed of 30 km/h applies beyond the sign
  3. A speed restriction applies only to goods vehicles
  4. A maximum speed limit of 30 km/h applies beyond the sign Correct answer.

Explanation

A red circle containing a number is a regulatory maximum speed limit, and the supplementary plate confirms the unit as kilometres per hour. The limit applies to all traffic unless a plate restricts it to a particular class.

Question 44Rules of the Road (road signage, road markings, traffic rules and regulations)

A truck driver is parked on a road at night in a built-up area where there is no street lighting. What lighting requirement applies?

  1. No lights are required if the vehicle is off the carriageway
  2. Headlights must be left on main beam
  3. Parking lights must be displayed so the vehicle is visible Correct answer.
  4. Hazard warning lights alone are sufficient

Explanation

Where a vehicle is parked on a road at night and the location is unlit or the vehicle cannot be seen clearly, parking lights must be shown so other road users can see it in time. Hazard lights are not a substitute for parking lights.

Question 45Rules of the Road (road signage, road markings, traffic rules and regulations)

A truck is approaching a junction where a continuous white line separates its lane from a lane intended for traffic turning right. What does the continuous line mean for the truck driver?

  1. The truck may cross the line to overtake slow traffic
  2. The truck must not cross the line to enter that lane Correct answer.
  3. The truck may cross the line if signalling
  4. The truck must change lane at the line

Explanation

A continuous white line must not be crossed except in the limited circumstances permitted by law, such as access to premises where it is safe. It is not a line that may be crossed simply to overtake or change lane.

Question 46Rules of the Road (road signage, road markings, traffic rules and regulations)

A truck driver is travelling on a motorway and the vehicle develops a mechanical fault. Where should the driver stop if possible?

  1. At the next exit on the slip road
  2. On the central reservation
  3. In the right lane with hazard lights on
  4. On the hard shoulder, as far left as possible, with hazard lights on Correct answer.

Explanation

A vehicle in difficulty on a motorway should be moved onto the hard shoulder as far left as possible, with hazard warning lights illuminated and occupants placed safely away from traffic. Stopping in a running lane creates a serious collision risk.

Question 47Rules of the Road (road signage, road markings, traffic rules and regulations)

A truck driver is stopped by a garda and asked to produce their driving licence. Within what period must the licence be produced if it is not available at the roadside?

  1. 10 days Correct answer.
  2. 24 hours
  3. 3 months
  4. 6 months

Explanation

Where a licence cannot be produced at the roadside, the driver is normally required to produce it at a garda station within 10 days. Failing to do so can lead to prosecution for the original offence.

Question 48Rules of the Road (road signage, road markings, traffic rules and regulations)

A truck driver is approaching a junction where the traffic lights are out of order and no garda is present. How should the driver proceed?

  1. Wait until the lights are repaired
  2. Sound the horn and drive through
  3. Proceed through at normal speed as the lights are off
  4. Treat the junction as a yield and proceed only when it is safe Correct answer.

Explanation

When traffic lights fail, drivers must approach with caution and apply the normal rules of the road, giving way as they would at an uncontrolled junction. Proceeding at speed or waiting indefinitely are both unsafe responses.

Question 49Rules of the Road (road signage, road markings, traffic rules and regulations)

A truck driver intends to enter a bus lane outside its operating hours to reach a loading bay. What is the correct position?

  1. Entry is permitted at all times for loading
  2. Entry is permitted only with hazard lights on
  3. Entry is never permitted for goods vehicles
  4. Entry is permitted outside the displayed operating times, subject to any other restrictions Correct answer.

Explanation

Bus lanes are marked with signs showing their operating times, and outside those times other traffic may generally use the lane, subject to any separate parking or loading restrictions. Within the operating times, unauthorised vehicles must keep out.

Question 50Rules of the Road (road signage, road markings, traffic rules and regulations)

A truck driver is involved in a collision in which a person is injured. What is the driver's immediate legal obligation?

  1. Report the collision only if damage exceeds a set amount
  2. Continue to the destination and report it later
  3. Exchange details only if the other driver requests them
  4. Stop, give assistance and report the collision to the gardaí Correct answer.

Explanation

Where a collision causes injury, the driver must stop, offer reasonable assistance and ensure the collision is reported to the gardaí. Leaving the scene or delaying the report can constitute a serious offence.
