Learning to Drive in Ireland can be an expensive lesson .To legally drive a car in Ireland you need a Drivers Permit.
The first step is to pass a Driver Theory Test . This costs €45 for a car and you have to be at least 17 years old before you can take the test. (if you are going to be driving a car). 
Type B test is for cars – and it is 40 questions in 45 mins and you must get 35 or more correct to pass. The test is computer-based but, is designed for those who have little or no experience of using computers as well as those who do.
You will need a copy of The Official Driver Theory Test Questions and Answers, Motorcycles, Cars and Work Vehicles – 6th Edition, October 2013
The second stage is to get a Learners Permit. You have to apply for a learner permit in person one of the National Driver Licence Service NDLS centres located around the country. You will be required to verify your identity with documentation to prove your identity, your address & your PPSN, as well as confirmation of your country of birth/residency entitlement.
Learner permits for cars and work vehicles are valid for 2 years (or 1 year in certain circumstances) and since January 2013 the fee is €35.
Eyesight report – A completed Driving Licence Eyesight Report Form must accompany all first learner permit applications. An eyesight report is not required where a medical report is provided unless indicated by the doctor.
The typical cost of a driving eyesight test is €20 or €25
Learner permit holders for cars must display L-plates to the front and rear of the vehicle they are driving at all times. The plate should be a red ‘L’ on a white background and should not be less than 15cm high with a border of at least 2cm
Before you can take a driving test and get a full drivers license you need to undertake a mandatory Essential Driver Training course. The EDT is made up of 12 one-hour lessons, which you must complete before taking your Driving test. This EDT requirement came into force in 2011 . Each lesson in the EDT covers a specific area of driving skills – the lessons are in a set order and must be recorded in you personal EDT logbook.
Cost of EDT – There is no set charge for EDT lessons and each driving instructor sets their own price.
A quick survey of sample prices found charges for 12 EDT lessons ranging from €294 to €499
Studying the Rules of the Road will be useful
All driving instructors that teach the EDT have to be approved by the Road Safety Authority (RSA)
There is no need for anyone to pay a third-party website to book a driving test or theory test, as it can be done at rsa.ie or theorytest.ie where the only cost you will incur is the cost of the test itself.
