Question 1
A Garda roadside check finds you have today's records, but last month's records were left at the depot. Have you carried what the law requires?
ANo, because you must also carry the records for the previous 56 daysCorrect answer
BYes, because records may be sent on from the depot afterwards
CYes, because only the current day must be in the vehicle
DYes, because 28 days of records is enough
Show the answerHide the answer
Correct answer: A
You must have with you the records for the current day and the previous 56 days. Leaving last month's records at the depot does not meet that duty, and sending them on later is not enough. This is the carrying duty in Article 36 of Regulation (EU) No 165/2014.
The major road is clear and this sign faces you at the junction. Does it require a full stop?
AYes, it always means stop
BYes, except when you are turning left
CNo, it requires you to yield right of way, not always to stopCorrect answer
DYes, if you are driving a large vehicle
Show the answerHide the answer
Correct answer: C
Regulation 29 of the Road Traffic (Traffic Signs) Regulations 2025 requires traffic facing the yield sign to yield right of way to traffic on the major road ahead. It does not always require a full stop, it does not give left-turn priority, and the rule is the same whatever you are driving.
A three axle articulated bus may exceed 25 tonnes but must not exceed which weight?
A25 tonnes, the general three axle limit for a bus
B28 tonnesCorrect answer
C26 tonnes
D19.5 tonnes
Show the answerHide the answer
Correct answer: B
A three axle articulated bus may exceed 25 tonnes but must not exceed 28 tonnes. The figure of 25 tonnes is the point above which that vehicle may go, and 26 tonnes belongs to a different rule. The source is the construction and use regulations for vehicles.
CWhenever the working day itself is longer than 9 hours
DNo more than twice in a weekCorrect answer
Show the answerHide the answer
Correct answer: D
Daily driving may be extended to 10 hours no more than twice in a week. A third longer day is not allowed, and neither an employer nor a longer working day can raise the driving cap. This is the daily driving limit in Article 6 of Regulation (EC) No 561/2006.
From every seat on a bus there must be unobstructed access to how many exits?
AAt least one exit, whatever the vehicle
BAt least three exits
CAt least two exits on the upper deck
DAt least two exits, or to one where only one is requiredCorrect answer
Show the answerHide the answer
Correct answer: D
There must be unobstructed access from every seat to at least two exits, or to one exit where only one is required. A route to a single exit in every case, or a route to exits on one deck only, does not meet the rule.
For how long must the owner keep the bus inspection, maintenance and repair records?
AAt least 6 months after the journey ends
BAt least 1 year
CAt least 5 years
DAt least 2 yearsCorrect answer
Show the answerHide the answer
Correct answer: D
The owner must keep the inspection, maintenance and repair records for at least 2 years. The records show how the vehicle has been maintained and are separate from the vehicle's test certificate. The source is the vehicle maintenance and repair regulations and the roadworthiness Act.
Slowing down for a junction, you see this sign. What does this sign tell you not to do?
AOvertake another vehicle
BTurn left
CTurn rightCorrect answer
DGo straight ahead
Show the answerHide the answer
Correct answer: C
Under Regulation 14(2)(a) of the Road Traffic (Traffic Signs) Regulations 2025, a prohibitory sign with an arrow means a vehicle must not go in that direction, and on the no right turn sign that is a right turn. The sign says nothing about turning left, going straight on or overtaking.
In an industrial estate, this sign faces you at a junction. What manoeuvre must you not make past it?
AThe sign allows a left turn when nothing is coming
BThe sign allows a left turn for a quick drop off
CTurning left past the signCorrect answer
DThe sign applies to large vehicles only
Show the answerHide the answer
Correct answer: C
Regulation 14 of the Road Traffic (Traffic Signs) Regulations 2025, Schedule 2, Part 1, makes the no left turn sign a prohibitory sign: you must not turn left past it. That is a different sign from no right turn. An empty road, a short drop off, or vehicle size does not lift the prohibition.
In the State, who has access to the driver CPC enforcement network?
AEvery employer of drivers
BThe Authority and members of the Garda SíochánaCorrect answer
CThe approved training centres
DAny member of the public who makes a written request
Show the answerHide the answer
Correct answer: B
Access in the State to the enforcement network is limited to the Authority and members of the Garda Síochána, and the Authority exchanges CPC information with other Member States through it. This is Regulation 21A of S.I. No. 359 of 2008, as inserted by S.I. No. 380 of 2021.
What is the default speed limit on a town street when no different limit applies?
A80 km/h
B60 km/h
C50 km/hCorrect answer
D30 km/h
Show the answerHide the answer
Correct answer: C
The built-up area speed limit under section 5 of the Road Traffic Act 2004 is 50 km/h. It applies to public roads in the area except motorways unless a special or roadworks limit applies.
What is the minimum age at which a person may apply for the initial driver CPC test in the passenger categories D and DE?
A21Correct answer
B18
C20
D23
Show the answerHide the answer
Correct answer: A
The age below which a person may not apply for the initial CPC test is 21 for the passenger categories D, DE, D1 and D1E, while it is 18 for the goods categories. This is the table in Regulation 7(3) of S.I. No. 359 of 2008, as substituted by S.I. No. 178 of 2020.
A regular bus service has a route of exactly 50 kilometres. Do the EU drivers' hours rules cover the drivers on it?
AYes, because the route is long enough to need a tachograph and a record sheet
BYes, because the service is open to the public and a timetable is published
CNo, and the drivers have no protection at all
DNo, because the route does not exceed 50 kilometresCorrect answer
Show the answerHide the answer
Correct answer: D
The Regulation leaves out a regular passenger service whose route does not exceed 50 kilometres, and a route of exactly 50 kilometres is within that limit. That does not leave the drivers unprotected, because the State must still protect their driving time, breaks and rest. The test is the length of the route, not who the passengers are or what equipment is on the bus. The source is the amended Regulation on social legislation relating to road transport.
CCyclists only as advice, so they may still go past
DPeople driving pedal cycles, e-mopeds and electric scootersCorrect answer
Show the answerHide the answer
Correct answer: D
Regulation 17 of the Road Traffic (Traffic Signs) Regulations 2025 provides that a person driving a pedal cycle, e-moped or electric scooter must not go past the sign. An e-moped is a pedal assisted electric bicycle. Motorcyclists and category AM moped riders are not caught by this sign, and it is not advice.
On a bus of category M2 or M3 with belts fitted, who must wear a safety belt or an appropriate child restraint?
AOnly adults, because a parent is fully responsible for a child on a coach
BOnly children under 3
COnly the passengers in the front rows
DEvery adult and every child aged 3 or over occupying a seatCorrect answer
Show the answerHide the answer
Correct answer: D
Where belts are fitted on a bus or coach of category M2 or M3, every adult and every child aged 3 or over occupying a seat must wear a safety belt or an appropriate child restraint. The duty does not turn on who is responsible for the child or on where the passenger is seated.
After leaving a parking place where the except buses plate applies, when may you return to that part of the roadway while the restriction applies?
ANot within an hour of leavingCorrect answer
BAfter 15 minutes
CAfter 45 minutes
DAt any time, because you drive a large public service vehicle
Show the answerHide the answer
Correct answer: A
A large public service vehicle may park at the except buses plate for no more than one hour and may not return to that part of the roadway within an hour of leaving while the restriction applies. The restriction stops a bus from holding the same place all day by moving off and back again.
Which passenger vehicles come within the commercial vehicle roadworthiness test?
AOnly vehicles with more than 16 seats that are used to carry passengers on scheduled routes
BPassenger vehicles with more than 8 seats excluding the driver's seat and a design speed above 25 kilometres per hourCorrect answer
COnly vehicles used on scheduled routes
DAll passenger vehicles, whatever their design speed, weight or seating layout
Show the answerHide the answer
Correct answer: B
The test covers passenger vehicles in categories M2 and M3 with more than 8 seats excluding the driver's seat and a design speed over 25 kilometres per hour. It is not limited to scheduled routes or to the largest buses. A vehicle whose design speed is at or below that figure is outside this test. The source is the commercial vehicle roadworthiness testing regulations.
The sign at a rural junction reads Géill Slí. What sign is that?
AA different sign used only in Irish-speaking areas
BThe same yield sign as one that reads Yield or Yield Right of WayCorrect answer
CA stop sign with an Irish legend
DA sign that always requires a full stop
Show the answerHide the answer
Correct answer: B
Under Regulation 29 of the Road Traffic (Traffic Signs) Regulations 2025, the yield sign may show Yield, Yield Right of Way, or Géill Slí. All three legends are the same sign. The Irish legend is not a different sign and it does not turn the yield sign into a stop sign.
