National Car Test


Compulsory car testing was introduced in Ireland in January 2000 as part of an EU Directive that makes car testing compulsory in all member states. It is an offence to drive a car that is liable for testing without displaying a National Car Testing Service disc and offenders will face Class C fines, as well as penalty points.

The test is called the National Car Test and is carried out on behalf of the Government by the National Car Testing Service Ltd (NCTS). The test is aimed at improving road safety and enhancing environmental protection. You can view NCT pass/fail rates here.

Format of the National Car Test

The central testing operation is based in Citywest Business Campus, outside Dublin, with a network of operating centres nationwide. The testing procedure is computer controlled and highly automated and provides maximum test security and accuracy.

The test cover among other things: brakes; exhaust emission; wheels and tyres; lights; steering and suspension; chassis and underbody; electrical systems; glass and mirrors; transmission; interior and fuel system.

Minor things such as broken windscreen wipers, wing mirrors or indicators will fail you just as easily as high emission levels, faulty steering or bad brakes. The single largest categories for car failures are problems with headlights, emissions and brakes. A pass certificate or a failure report is issued after the test and if the car fails, the report explains why and what needs to be done.

The National Car Test (NCT) Manual (pdf) is available on the NCT website

The NCTS recommends that you prepare for the test by ensuring that:

  • Your car has adequate oil and water
  • The boot is empty and seats are clear of personal belongings such as removable baby seats
  • The vehicle is reasonably clean (especially the underbody)
  • The wheel hubcaps are removed and the tyres are inflated to the correct pressure
  • Seat belts and clips are fully visible
  • Your vehicle registration plates comply with current regulations
  • The timing belt has been replaced in the case of a diesel vehicle, i.e., within the timeframe specified by the vehicle manufacturer
  • NCT recommend you have your lights checked and set prior to the test.

If you do get your car serviced, the NCTS advises that special attention is paid to the most common failure points:

  • Headlights: alignment and condition
  • Brakes: front, rear and hand brake
  • Exhaust emissions: in most cases a slight tuning of the engine is sufficient.


Since 2000 onwards, all cars 4 years and over are tested. Vehicles that pass the test will have to undergo repeat tests every 2 years. Since June 2011, cars over 10 years old are tested each year.

Since 28 July 2014, you can submit your vehicle voluntarily for the test any time before the test due date and receive an NCT certificate which is valid for 1 or 2 years (depending on the age of the car) from the date of the test.

You must bring your vehicle registration/licensing certificate with you to the test centre. You are also required to produce your driving licence or passport as identification.

Exemptions from NCT

Vehicles registered before 1 January 1980 are not required to be tested.

Cars permanently based on islands that are not connected to the mainland by road do not have to be tested.


In the case of car-vans that have their rear side-windows blocked off, you should contact the Road Safety Authority (Tel: 091 872 600) for further information.

Vehicles imported from Northern Ireland and abroad

Vehicles imported to Ireland from outside the State (including Northern Ireland) must also go through the NCT once the vehicle is 4 years old or more. This applies even if the vehicle previously received an MOT or any other vehicle test abroad. If the imported vehicle is already 4 years old or more when imported, it must go through the NCT immediately. For more information about the NCT and imported cars contact the NCT Customer Services Department on 1890 200 670.

Appealing NCT results

If you are dissatisfied with the test result you may appeal it through the NCTS appeal process. In the first instance you should raise your concerns with the person in charge of the Test Centre before leaving. Information on making a complaint or an appeal is available on the NCT website.


The test costs €55 and takes between 40 minutes - 1 hour to conduct. It involves approximately 60 different checks which will be carried out both by computer and manually.

According to the NCTS Customer Charter if you request an NCT appointment within 4 weeks and it cannot be provided, you are entitled to have the test carried out for free.

If your car fails the test, you must book a re-test within 21 days and the re-test must be completed within 30 days of the original test. A re-test costs €28. Re-tests that do not require the use of test equipment are free. (Free re-tests include minor visual items such as the replacement of a windscreen wiper).

If you cancel your confirmed appointment with less than 5 working days notice (Monday-Friday, not including the day of the test) or if you do not turn up for your test, you will be charged an extra €22 (on top of the usual fee) when you next bring your vehicle for testing.
