ExploreAbout this exam
The Ireland Truck & Bus Theory Test is the driver theory test category that a candidate must pass before applying for a learner permit to drive trucks or buses on Irish public roads. The Road Safety Authority (RSA) describes the theory test as the step that comes before the learner permit and the driving test, and it directs candidates to theorytest.ie to book, reschedule or cancel a test and to see the categories of test available. This guide is independent study material and is not affiliated with, endorsed by or operated by the RSA; always confirm booking, fee and format details on the official theorytest.ie service before you commit money or a date. The multiple-choice test samples knowledge across four areas: Rules of the Road, road safety and hazard awareness, vehicle safety and maintenance, and professional driver knowledge such as drivers' hours and tachographs - the last area matters because truck and bus drivers are professional drivers under the Driver CPC system. Preparation should combine the official Rules of the Road publication with the official revision material for your test category, then repeated practice on scenario-based questions about large-vehicle handling, load security, walkaround checks and record keeping. Note that the RSA website carried a service-disruption notice about a national day of industrial action on Wednesday 21 October, so check service status before travelling to a test centre. Question count, duration, pass mark and fee are not confirmed here and are marked for review.
What you'll study
About Ireland Truck & Bus Theory Test preparation
Who needs to sit the Truck & Bus theory test?
Anyone who wants a learner permit for a truck or bus category must first pass the theory test for that category. The RSA lists the theory test as part of the learner driver journey, ahead of the learner permit and the driving test. Confirm the exact category you need on theorytest.ie before booking.
How do I book, reschedule or cancel?
Booking is handled through theorytest.ie, which the RSA links to for booking, rescheduling or cancelling a theory test and for information on the categories of test available and sitting the test online. Use that official service rather than a third-party site, and check for service disruption notices before your date.
What does the test actually cover?
Expect multiple-choice questions on Rules of the Road, road safety and hazard awareness, vehicle safety and maintenance, and professional driver topics such as drivers' hours and tachographs. The professional element reflects that truck and bus drivers fall under Driver CPC requirements. Use the official revision material for your category as your primary source.
How many questions are there, how long is it, and what is the pass mark?
We cannot confirm these figures. The RSA theory test page returned a 'page not found' error when checked, so the question count, duration, pass mark and fee are unverified here and flagged for review. Check theorytest.ie directly, as these details are set officially and can change.
What happens if I fail - can I retake it?
Retake arrangements and any waiting period are set by the official test operator and were not confirmed in our source material, so treat any figure you see elsewhere with caution. Check theorytest.ie for current retake rules and fees. Build in extra study time before rebooking rather than repeating the same preparation.
How should I structure my study?
Start with the official Rules of the Road publication, then work through the official revision material for the truck and bus category. Give separate blocks to vehicle safety and maintenance and to drivers' hours and tachographs, since these are the areas car-focused study usually skips. Finish with timed practice and review every wrong answer.
What are the most common ways candidates lose marks?
Weak spots tend to be the professional material: drivers' hours limits, tachograph record keeping, and daily walkaround checks. Candidates also misjudge stopping distances and safe following gaps for heavy vehicles, and rush scenario questions about vulnerable road users. Slow down on these topics rather than memorising answers.
Is this guide official?
No. This is independent study material and makes no claim of affiliation with the RSA or the official test operator. Use it for practice and orientation, but rely on official RSA and theorytest.ie sources for booking, fees, format and the rules you will be tested on.
Could industrial action affect my test date?
Possibly. The RSA site carried a notice that some RSA services would be disrupted by a national day of industrial action across the public service on Wednesday 21 October. Check the RSA service status and your booking before travelling, and allow time to reschedule if your centre is affected.
