You can also check the expiry date of a NCT Certificate on the NCT website to ensure the validity of a Certificate.

Changes to the NCT (from 28th July 2014)

The Road Safety Authority (RSA) has introduced a number of customer service enhancements to NCT tests. These new measures help to improve road safety in general and contribute to protecting consumers from fraud.

These enhanced safety measures are effective from 28 July 2014:

Customer Survey Optout

The Road Safety Authority contacts a sample of customers for the purposes of customer service research . If you do not wish to be contacted to undertake customer service research please send your name and address to: and you will not be included in any future surveys.

Remember to bring ID ! 

Anybody who is presenting a vehicle for an NCT is required to produce their Driving Licence (or Passport) as a form of identification. Please ensure you bring your Driving Licence (or Passport) with you when presenting a vehicle, otherwise the NCTS may not be able to carry out the test. This is required to prevent fraud and to help facilitate investigations and appeals. All data checking is carried out in accordance with Data Protection requirements.

For bookings made at the test centre, only driving licences or a Trade Management Fob will be accepted from 28th July 2014.

Annual testing of cars 10 years and older

Annual testing of cars 10 years and older was introduced on 1 June 2011.  Cars presented for their 10th anniversary or subsequent NCTs will receive a certificate valid for up to one year only.  From 28 July 2014, where a vehicle has already undergone a voluntary early test and the test due date has been reset, if this vehicle passes the test within 90 days of the 10th anniversary of first registration, a certificate valid to the 11th anniversary will be issued, and the test due date will be reset to the anniversary of first registration. 

There is a need to ensure that older vehicles are frequently maintained and are fit for purpose on our roads. The RSA has prepared a FAQ document(PDF) to assist with any queries in relation to testing of cars 10 years and older.


The NCTS is committed to providing the service to the highest standards in customer service, quality and test integrity. Integrity is an important element of the National Car Test. If you feel the integrity of the service has been compromised in any way and would like to speak with someone in confidence; you can do so either by phone or email on the following:

What is the NCT?

Introduced in 2000, the National Car Test (NCT) is a preventative road safety measure that ensures vehicles using Irish roads are subject to a basic safety check at regular intervals. 

All member states of the European Union are required to carry out a periodic test inspection of motor vehicles at regular intervals throughout their lifecycle.

An NCT certificate confirms that the vehicle has satisfied a basic standard of safety at the time of the test and the expiry date on the certificate indicates the last date before the next test is due for the vehicle. Further information on the duration of an NCT certificate can be found in our information note (PDF).

The owner has the statutory duty to ensure that his/her vehicle remains in a satisfactory roadworthiness condition and complies with the relevant provisions of the Road Traffic (Construction, Equipment and Use of Vehicles) Regulations 1963-2006 at all times when it is used in a public place. The NCT does not replace or purport to replace the regular maintenance that a mechanic needs to carry out on a car.


Test Frequency

Age of Vehicle Test frequency
0-3 years No test required
4-9 years Every two years
10 years plus (10th anniversary)     Annually, from June 2011
Cars registered before 1.1.1980 No test required


Booking an NCT

There are 47 NCT test centres located throughout Ireland established solely for the purposes of car testing. Find the centre that is most convenient to you.

From July 28, 2014, car owners and members of the motor trade will be able to book an NCT test at any point prior to their next mandatory test. Previously, NCT tests could only be booked within 90 days of a vehicle’s test due date or 180 days in the case of a first NCT. From 28 July 2014, any test undertaken more than 90 days in advance of the test due date will be a voluntary early test and the test due date will be reset to the one or two year anniversary of the successful test (depending on the age of the vehicle).

The car test fee is €55 (inclusive of VAT). NCTS will accept cash, debit cards and all major credit cards (excluding American Express).

The fee for a re test is €28 if the use of a test lane is required. A re-test that doesn’t require the use of a test lane or requires the use of test equipment for the purposes of carrying out an inspection of tyres only is free of charge.

Note: If you wish to cancel or rearrange a test you must give the NCTS five working days’ notice (not including the day of the test). If you give less notice than this a €22 surcharge (€11.50 in the case of a retest) will be applied. From July 28, 2014 customers who repeatedly fail to present their vehicle for testing, without giving the required notice, will be presented with a €22 surcharge (€11.50 for a re-test) on each occasion that an appointment is missed.

 Any queries relating to the cancellation fee may be made in writing to the Customer Service Department, National Car Testing Service, Lake Drive 3026, Citywest Business Campus, Naas Road, Dublin 24.

What the test examines

During the NCT, specific items are checked and tested. These include:

  • Brakes
  • Exhaust emissions
  • Wheels and tyres
  • Lights
  • Steering and suspension
  • Chassis and underbody
  • Electrical systems
  • Glass and mirrors
  • Transmission
  • Interior
  • Fuel system

You can view a full list of the items which are covered in the National Car Test in the newly revised National Car Test (NCT) Manual 2014 (PDF).

Note: the tests undertaken by the NCT evolve over time as industry safety technologies improve and new safety concerns arise. A number of new test items were introduced in April 2010, January 2012 and July 2014.

Benefits of testing

  • Safer, more reliable cars
  • Longer vehicle service life
  • Reduced fuel consumption
  • Reduced air and noise pollution
  • Avoidance of penalty points. Since 1 May 2009, you can receive penalty points for not having a valid NCT.

Pass rates & Statistics

In 2016 the NCTS carried out 1.46m full tests on private cars, the second highest year on record.  When the NCT was first introduced in 2000, just 309,434 full tests were undertaken.   At that time the pass rate on the first attempt was just under 4%, compared to over 80% in 2016 for cars that are four years old.   The NCT is a key contributor to the roadworthiness of vehicles and also is an important preventative road safety measure that ensures vehicles, particularly older vehicles, using Irish roads are in sound working order.

Fail Dangerous

Where a vehicle has a dangerous defect i.e. a defect that constitutes a direct and immediate risk to road safety such that the vehicle should not be used on the road under any circumstances, the NCT vehicle inspector will issue a Failed Dangerous result. 

It is an offence to drive a dangerously defective vehicle on the public road.  The penalty for such an offence is a fine of up to €2,500 and 5 penalty points on conviction and/or 3 months imprisonment, (Offence under Section 54 of the Road Traffic Act 1961 and related amendments).

When the result is Failed Dangerous the NCT vehicle inspector will advise you as follows:

  • Of the existence, extent and nature of the defect.
  • That if you drive a mechanically propelled vehicle in a public place while there is a defect affecting the vehicle which you know of or could have discovered by the exercise of ordinary care and which is such that the vehicle is, when in motion, a danger to the public, you shall be guilty of an offence.
  • That in the opinion of NCTS the vehicle is dangerous.
  • That you must make arrangements to have the vehicle removed from the test centre.

A sticker stating “Failed Dangerous” will be attached to the vehicle and the vehicle inspector will issue you with a statement regarding requirements for vehicles with a failed dangerous result.


All re-tests must be booked within 21 days of the initial test.  The fee for a re-test is €28 if the use of a test lane is required. A re-test that doesn’t require the use of a test lane or requires the use of test equipment for the purposes of carrying out an inspection of tyres only is free of charge, e.g. where minor visual items are concerned, such as replacement of windscreen wiper and registration plates.

Re-tests must be completed within 30 days of the initial test or a full test will need to be repeated and charged accordingly.

From July 28, 2014, customers who fail to present their vehicle for a retest appointment, without giving prior notice, will be issued with an €11.50 cancellation fee on each occasion that a retest is missed. Previously, a single €11.50 cancellation fee for a retest was applied if one or more tests were missed. Owners who repeatedly book and then fail to show up to tests, without giving prior notice, prevent others from booking tests at times that are convenient to them.

New NCT Regulations

Legislation governing the mandatory testing of cars has been consolidated into The Road Traffic (National Car Test) Regulations 2014, S.I. 322 of 2014 (PDF).
