Question 1
Your driver card has passed its expiry date but the unit still reads it without error. May you use it?
ANo, a defective or expired driver card must not be usedCorrect answer
BYes, because the unit accepted the card without an error
CYes, because the card still carries the driver identity details
DYes, while the application for a new card is being processed
Show the answerHide the answer
Correct answer: A
A driver must not use a defective or expired driver card. The fact that the equipment still reads the card does not make its use lawful. This is Article 27(2) of Regulation (EU) No 165/2014.
What groups of items does the walk around check on a goods vehicle include, so far as they apply?
AIn cab items, the exterior of the vehicle, and checks made with the engine startedCorrect answer
BOnly the tachograph modes
COnly the load documents
DOnly the coupling on a trailer
Show the answerHide the answer
Correct answer: A
The walk around check includes the Schedule 1 items so far as they apply: in cab items, the exterior of the vehicle, and checks made with the engine started. Load security and weight distribution sit among the exterior items. Tachograph modes, load documents, or the coupling alone are not the full groups. This is the walk around items rule in regulation 8 and Schedule 1 of the Road Safety Authority (Commercial Vehicle Roadworthiness) (Vehicle Maintenance and Repair) Regulations 2013.

BOvertaking is not allowed
CVehicles longer than the length shown must not go pastCorrect answer
DPeople riding, leading or driving animals must not go past
Show the answerHide the answer

DConditions on weight, dimensions, speed, trailer numbers, springs, tyres and wheelsCorrect answer
Show the answerHide the answer
Correct answer: D
The permit may carry conditions on weight, dimensions, speed, trailer numbers, springs, tyres and wheels. Drivers' hours, vehicle colour, or the customer's name are not the conditions this rule names. This is the special permit rule in regulation 3 of the Road Traffic (Special Permits for Particular Vehicles) Regulations 2007.
Which statement about the exception Ireland has made under Article 13(1) is correct?
AIt applies to every goods vehicle in the State whatever operation it is doing
BIt applies only while the vehicle is operating in the StateCorrect answer
CIt applies to the listed operations throughout the European Union
DIt applies only on journeys that cross a border
Show the answerHide the answer
Correct answer: B
The Irish exception covers the listed operations while they are carried out in the State, and it excepts them from Articles 5 to 9 of Regulation (EC) No 561/2006 and from the named tachograph instruments. It has no effect on operations in other Member States. The source is Regulation 4(1) of S.I. No. 229 of 2017, as substituted by S.I. No. 567 of 2023.

ASign A
BSign BCorrect answer
CSign C
DSign D
Show the answerHide the answer

How is rear overhang measured on a rigid goods vehicle, and what is the cap?
AFrom the centre of the rear axle, or the midpoint between the rear two axles, to the rearmost point, and it must not exceed 60 per cent of the distance from the front wheel centre to that rear reference planeCorrect answer
BFrom the front bumper to the tail, and it must not exceed 50 per cent of the vehicle length
CFrom the king pin to the tail, and it must not exceed 12 metres
DFrom the cab rear to the tail, and it must not exceed 3 metres
Show the answerHide the answer
Correct answer: A
Rear overhang is measured from the centre of the rear axle, or the midpoint between the rear two axles, to the rearmost point, and must not exceed 60 per cent of the distance from the front wheel centre to that rear reference plane. A 50 per cent body-length figure, a 12 metre king-pin figure, or a 3 metre cab-to-tail figure is not this rule. This is the rear overhang rule in regulations 46 and 47 of the Road Traffic (Construction and Use of Vehicles) Regulations 2003.
Sign D is the no overtaking sign. It is a prohibitory sign in Part 1 of Schedule 2 to the Road Traffic (Traffic Signs) Regulations 2025. Article 10(3) of the Road Traffic (Traffic and Parking) Regulations 1997 says a driver must not overtake, or try to overtake, on a stretch of road where it is provided.
The two axles of a tandem on your goods vehicle are 1.5 metres apart. What is the tandem weight limit, without the extra 19 tonne conditions?
A16 tonnes
B18 tonnesCorrect answer
C11.5 tonnes
D24 tonnes
Show the answerHide the answer
Correct answer: B
At 1.3 metres to under 1.8 metres the tandem limit is 18 tonnes unless the extra driving-axle conditions for 19 tonnes are met. 16 tonnes is the tighter spacing band, 11.5 tonnes is the under 1.0 metre band, and 24 tonnes is a triaxle figure. This is the tandem axle weight rule in regulation 6 of the Road Traffic (Construction and Use of Vehicles) Regulations 2003, as substituted by the Road Traffic (Construction and Use of Vehicles) (Amendment) (No. 2) Regulations 2014.
What is the ordinary daily driving time limit under the EU drivers' hours rules?
A8 hours
B9 hoursCorrect answer
C11 hours
D12 hours
Show the answerHide the answer
Correct answer: B
The daily driving time shall not exceed nine hours. A longer day is a limited exception, not the ordinary cap, and 8, 11 or 12 hours are not the figure. This is the daily driving limit in Article 6 of Regulation (EC) No 561/2006.
Where must the disc attached to a goods vehicle's certificate of roadworthiness be displayed?
AOn the front windscreen where the vehicle has one, and otherwise on the near side where it is clearly visibleCorrect answer
BInside the tachograph head, out of sight
COn the rear doors only
DIn the operator's office, not on the vehicle
Show the answerHide the answer
Correct answer: A
The disc must be displayed on the front windscreen where the vehicle has one, and otherwise on the near side where it is clearly visible. Hiding it in the tachograph, putting it only on the rear doors, or leaving it in the office is not the rule. This is the disc display rule in regulation 27 of the Commercial Vehicle Roadworthiness (Vehicle Testing) (No. 2) Regulations 2013.
How often must you use a record sheet or your driver card?
AOnly on international work
BEvery day on which you driveCorrect answer
COnly on days with a long run
DOnce a week when you return to the depot
Show the answerHide the answer
Correct answer: B
Drivers shall use record sheets or driver cards every day on which they drive. The duty is not limited to international work or long runs, and a weekly return to the depot is not the recording interval. This is the recording duty in Article 34 of Regulation (EU) No 165/2014.
When is the first commercial vehicle roadworthiness test due on a goods vehicle?
AOn the third anniversary of first registration
BSix months after first registration
COnly when the owner sells the vehicle
DOn the first anniversary of its first registrationCorrect answer
Show the answerHide the answer
Correct answer: D
The first test for a goods vehicle is due on the first anniversary of its first registration. The third anniversary, six months, or a sale is not the first due date. This is the test due date rule in regulation 6 of the Commercial Vehicle Roadworthiness (Vehicle Testing) (No. 2) Regulations 2013, as substituted by the Commercial Vehicle Roadworthiness (Vehicle Testing) (Amendment) Regulations 2018.
You are about to turn onto a narrow road with tight bends and see this sign. What does it say you must not do?
ADrive past in a vehicle narrower than the width shown
BDrive past in a vehicle taller than that figure in metres
CDrive past in a vehicle wider than the width shownCorrect answer
DDrive past in a vehicle longer than that figure in metres
Show the answerHide the answer
Correct answer: C
This is the maximum vehicle width sign. Regulation 26 of the Road Traffic (Traffic Signs) Regulations 2025 provides that the driver of a vehicle wider than the width shown, in metres, must not go past it. It does not limit height or length, and a narrower vehicle may go on.
You drive an Irish registered truck on an international journey that runs partly outside the European Union, Switzerland and the EEA. Which hours rules govern that journey?
AThe AETR applies instead of Regulation (EC) No 561/2006 for the whole journeyCorrect answer
BRegulation (EC) No 561/2006 applies in full for the whole journey
CThe hours rules of the country where the vehicle is registered always decide
DOnly Irish national hours rules apply, because the journey began in the State
Show the answerHide the answer
Correct answer: A
For a vehicle registered in the Community, or in a country that is party to the AETR, the AETR applies instead of the Regulation for the whole of an international journey that runs partly outside the Community, Switzerland and the EEA. This is Article 2(3)(a) of Regulation (EC) No 561/2006, read with Article 2(2).
When is an undertaking using goods vehicles outside the operator licensing rules?
AThey do not apply to undertakings using only vehicles or combinations not exceeding 3.5 tonnes engaged exclusively in national transport, nor to those using only vehicles not exceeding 2.5 tonnesCorrect answer
BThey always apply, whatever the weight or the work
CThey do not apply to any international goods work
DThey do not apply once a merchandise licence is held
Show the answerHide the answer
Correct answer: A
The rules do not apply to undertakings using only vehicles or combinations not exceeding 3.5 tonnes engaged exclusively in national transport, nor to those using only vehicles not exceeding 2.5 tonnes. They are not universal, they do apply to international goods work above those figures, and a merchandise licence is not the exclusion. This is the operator licensing scope rule in Article 1 of Regulation (EC) No 1071/2009.
You complete part of your compulsory periodic retraining in another Member State. Does that training count towards your current training cycle?
ANo, only training completed in the State counts
BNo, the training must be repeated in the State
CNo, training abroad counts only in the next training cycle
DYes, it is taken into consideration in the current training cycleCorrect answer
Show the answerHide the answer
Correct answer: D
Compulsory periodic retraining completed in another Member State is taken into consideration in the current CPC training cycle. Training is not confined to the State. This is Regulation 12(8) of S.I. No. 359 of 2008, as inserted by S.I. No. 178 of 2020.
BYour employer or the training centre that issued your records
CAny employee of the Authority, on production of an identity card
DA member of the Garda Síochána or a transport officerCorrect answer
Show the answerHide the answer
Correct answer: D
A member of the Garda Síochána or a transport officer may ask a driver for the driver CPC at any time, and failure to produce it is an offence. This is Regulation 17(4) and (5) of S.I. No. 359 of 2008.
The sole driving axle on your rigid has twin tyres but not air suspension. What is the greatest weight that axle may put on the road?
A10 tonnes, the same as every other single axle
B10.5 tonnesCorrect answer
C11.5 tonnes without any further condition
D16 tonnes, as if it were a tandem axle
Show the answerHide the answer
Correct answer: B
A sole driving axle with twin tyres is limited to 10.5 tonnes. 10 tonnes is the general single axle figure, 11.5 tonnes also needs air suspension or an equivalent system, and 16 tonnes is a tandem axle figure. This is the single axle weight rule in regulation 5 of the Road Traffic (Construction and Use of Vehicles) Regulations 2003, as substituted by the Road Traffic (Construction and Use of Vehicles) (Amendment) (No. 2) Regulations 2014.
