NCT Checklist: How to Get Your Car Ready and Avoid a Re-Test

NCT centres in Ireland are now reopening, and if your test is due, it’s time to start preparing. The National Car Test (NCT) is a mandatory inspection for vehicles, designed to improve road safety and reduce harmful emissions.

Delaying or avoiding your NCT can lead to penalty points and fines, so don’t put it off. Here’s a simple checklist to help you pass the test on the first try.

How to Prepare for the NCT Test

1. Clean Your Car Thoroughly

A clean vehicle makes it easier for the inspector to do their job. Be sure to:

  • Wash the exterior, especially mirrors, windows, lights, and number plates
  • Clean the interior, including under the seats and in the boot
  • Brush out dirt from the underbody—this area is also inspected

2. Remove All Personal Items

Clear out any personal belongings, especially from the boot. If you have a child car seat, the inspector will need to verify that it’s installed correctly.

3. Check All Seat Belts

  • Make sure each seat belt is visible, not frayed, and working properly
  • Test the clips to ensure they fasten and release smoothly

4. Top Up All Fluids

Before your test, check and top up the following:

  • Engine coolant
  • Brake fluid
  • Engine oil
  • Power steering fluid
  • Windscreen washer fluid

These are easy to check under the bonnet, but consult your manual if unsure.

5. Inspect All Lights and Indicators

Even a single blown bulb can result in an automatic fail. Check all the following:

  • Indicators (front, rear, and side)
  • Dipped and high beam headlights
  • Brake lights
  • Fog lights (front and rear)
  • Number plate lighting
  • Parking and tail lights

Ask a friend to help check the rear lights and brake lights while you press the pedal.

6. Check Tyre Condition and Pressure

  • Minimum legal tread depth is 1.6mm
  • Look for any visible cuts or bulges
  • Remove wheel hubcaps if required for the test
  • Check tyre pressure and adjust as per manufacturer guidelines

7. Examine Your Wipers

Ensure both front and rear wipers:

  • Operate smoothly
  • Don’t leave streaks
  • Are not cracked or worn

8. Check Your Registration Plates

Your number plates must be:

  • Securely fastened
  • Clean and clearly visible
  • Compliant with Irish vehicle registration plate regulations

9. Look for Dashboard Warning Lights

If any warning lights (e.g., engine, airbag, ABS) are on while the engine is running, get them checked. This can result in an instant fail—and may indicate your car isn’t roadworthy.

10. Bring All Necessary Documents

Don’t leave home without:

  • Vehicle registration book or certificate
  • Valid ID
  • Payment method (some centres are card-only)

11. Be Early and Plan Ahead

Start preparing at least a week before your test. If you discover any issues, this gives you time to get repairs done. Arrive at the test centre early so you don’t lose your slot.

Bonus Tip: Get a Pre-NCT Service

Even if your car looks fine, an underlying mechanical issue could cause a fail. Many drivers choose to get a quick pre-NCT service from a trusted mechanic to increase their chances of passing.

Check If Your NCT Is Due

Final Reminder: Stay Insured

Make sure your car insurance is up to date before driving to your test. Driving without insurance is illegal in Ireland and can lead to severe penalties.
