National Car Test

Driving a car in Ireland without displaying a National Car Testing Service disc is an offence if the car is liable for testing. Offenders can face a fixed charge fine, as well as penalty points.

The test is called the National Car Test. It is carried out by the National Car Testing Service Ltd (NCTS). The test aims to improve road safety and enhance environmental protection. You can view NCT pass/fail rates.

If your car is 4 years or older, it must take a test. How regularly you repeat the test depends on the age of your car. You must repeat the test:

• Every 2 years, if your car is over 4 years old and less than 10 years old
• Every year, if your car is over 10 years but less than 30 years old
• Every 2 years, if your car is between 30 and 39 years old and you are not using it for commercial purposes

The person taking the car to the NCT must bring the cars vehicle registration or licensing certificate to the test centre. They must also bring their driving licence or Public Services Card (PSC) as identification.

NCT appointments

The latest booking information is available on the NCT website.

NCT fee increases from 1 January 2025

From 1 January 2025, the cost for an NCT test will increase from €55 to €60, and the price of a re-test will increase from €28 to €40. The cost of cancelling a test within 5 days of booking will increase from €22 to €24.

NCTS has a network of operating centres nationwide. You must bring your car to one of these test centres to take the test.

The test looks at:

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

An on-board diagnostics testing system (OBD) is used during an NCT inspection. It scans your vehicle for its vehicle identification number, the odometer reading, the electronic braking system and the anti-lock braking system.

On-Board Fuel Consumption Monitoring (OBFCM) data has been collected as part of the NCT test. This ensures that the car's CO2 emissions and fuel or energy consumption values meet EU regulations. If you do not want this data stored, you can email your name, address and car registration number to privacy@ncts.ie. This only applies to the current test cycle and not future tests. All data collected will be anonymized. Find out more on the NCT website.

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 the seats are clear of personal belongings such as removable baby seats
• Your glove compartment is unlocked and clear of personal belongings (allow for OBD testing)
• Any devices using the OBD port in the vehicle are removed in advance
• 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 a diesel vehicle within the timeframe specified by the vehicle manufacturer
• Your lights have been checked and set before the test.

The NCTS has a checklist of what to check before your NCT to help you prepare for your test.

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

• Headlights: alignment and condition
• Suspension and steering
• Brakes: front, rear, and hand brake

All vehicles receive an NCT Vehicle Inspection Report after the test. The report details test results and explains what faults (if any) have been found. You will also receive a pass certificate if your car has passed the test.

There are 3 types of test results that you can get. A minor result, a major result, or a dangerous result.

Minor test result

The vehicle has passed the test with minor faults. These faults must be repaired and re-inspected by NCTS before you can get an NCT certificate.

Major test result

The vehicle has failed the test. You have 30 days to get your vehicle repaired and re-inspected by NCTS. If it passes the re-inspection, you will get an NCT certificate. If you do not have the vehicle re-inspected within 30 days, you will have to do the full test again.

Dangerous test result

The vehicle has failed the test because of a dangerous defect that poses a direct or immediate risk to road safety. The NCTS will put a ‘failed dangerous’ sticker on your car. It is illegal to drive a vehicle with a dangerous defect. If you continue driving your car and you get stopped by An Garda Síochána, you may get penalty points or have to go to court. You must get the vehicle repaired and re-inspected by NCTS within 30 days. If it passes the re-inspection, you will get an NCT certificate.

Your car can be tested 90 days before its due date. Your NCT certificate is valid for 1 or 2 years (depending on the age of the car) from its due date.

If you book a test that is more than 90 days earlier than the test due date, this test will be a voluntary early test. The NCT certificate issued will be valid for 1 or 2 years (depending on the age of the car) from the date of the successful test.

Vehicles registered before 1 January 1980 or vehicles that have reached the 40th anniversary of their first registration do not need to be tested. However, if a vehicle is over 40 years old and is used for commercial reasons, such as a wedding hire vehicle, a test is needed.

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

Motor vehicles belonging to the Armed Forces, the Garda Síochána or the Fire Service are not subject to mandatory testing.

If you are importing a car from another EU country and you have a current EU Roadworthiness Certificate, you can continue to use it in Ireland until it expires. You no longer transfer the unexpired portion of an EU certificate for a mutual recognition cert. You should apply and pass the NCT before the expiry of your EU Roadworthiness Certificate. See the FAQs on nct.ie. Read more about importing a vehicle into Ireland.

Appealing NCT results If you are dissatisfied with the test result, you can 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.

If you lose or misplace your NCT certificate, you can get a replacement certificate. You must complete the application form (pdf) (RF134) which is available from your local Garda station. The form must be stamped and signed by the Gardaí.
