Frequently Asked Questions
Is ie-dtt-truck a valid Ireland Driver Theory Test target?
Yes. RSA lists Heavy Commercial Vehicles as category C, and TheoryTest.ie publishes category C/D theory-test timing, question count and pass mark. RSA also publishes the category C truck theory-test fee and two-year certificate validity.
How many questions are on the Ireland truck theory test?
TheoryTest.ie publishes 100 questions for category C or D, with a 120-minute time limit and a pass mark of 74 correct answers.
How much does the category C truck theory test cost?
RSA publishes a EUR72 fee for either category C truck or category D bus. The combined category C and D test is published at EUR84.
How long is the truck theory test certificate valid?
RSA states that a truck, bus or combined bus and truck theory-test certificate is valid for up to two years. If it is not exchanged for a learner permit within that time, the test must be paid for and sat again.
Does passing category C theory give Driver CPC?
No. Category C theory is part of the learner-driver licensing route. Driver CPC is a separate professional-driver qualification requirement for most professional truck and bus drivers unless an exemption applies.
Does RSA publish a truck theory-test pass rate?
No official category C pass rate was found in the RSA, TheoryTest.ie or NDLS sources reviewed on 2026-05-30, so this metadata intentionally does not invent one.
