Pass Your NCT with Confidence

The National Car Test (NCT) helps keep vehicles safe and roadworthy. Required at 4 years old, every 2 years thereafter, and annually from 10 years old, these practical NCT tips can help improve your chances of a first-time pass.

The test is mandatory and driving a vehicle without a valid NCT certificate can result in fines up to €2,500

and prevent you from filing a claim against your insurance if you are in an accident.

NCT certificate

Since more than half of all vehicles fail the first inspection, taking the precautions below can significantly increase your chances of passing the NCT on the first attempt.

What to do before your NCT Booking

  1. Bring your driving licence, photo ID and vehicle registration certificate.
  2. Clean your vehicle inside and out, including lights, mirrors, windows and registration plates.
  3. Check tyre tread depth (minimum 1.6mm) and ensure all tyres are correctly inflated.
  4. Test all headlights, brake lights, indicators, wipers, horn and handbrake.
  5. Top up essential fluids, including engine oil, coolant and washer fluid.
  6. Ensure seat belts, doors, bonnet and boot are working correctly.
  7. Remove personal belongings, empty the boot and make the spare tyre accessible.
  8. Check that no dashboard warning lights are illuminated.
  9. Remove any OBD devices and keep the glovebox unlocked for inspection access.
  10. Drive the vehicle before the test so the engine reaches normal operating temperature.

NCT Tip: Faulty lights and incorrect headlamp alignment are among the most common reasons vehicles fail an NCT inspection, so check them carefully before your appointment.

OBD Testing Requirements

During the NCT, your vehicle’s On-Board Diagnostics (OBD) system may be checked for faults or warning lights. Making sure there are no active warnings before your test can help improve your chances of passing. new-changes-to-nct-form-21st-june-2021.pdf
