ALERT: NCT reveal bizarre reason you never knew could see your car fail test

The NCT service has warned drivers their cars could fail the NCT for little-known reasons, including 'decorations' near the windscreen. 

Testers took to social media to share the warning as they posted images of just some reasons a car could be failed. These included a set of novelty dice hanging from the rearview mirror, a dashcam partially blocking the windscreen, wires dangling in front of the windscreen and a cracked windscreen.

Their post read: "Did you know visibility issues can cause your car to receive a visual fail in its NCT? Keep your car on the road with these simple checks: Top up the screen wash and make sure the washers are working properly; Replace wiper blades if they smear or don't clear the wiped area effectively; Ensure your view isn’t blocked by any decorations on your dashboard.

"Taking care of these small details can be the difference between a pass or a fail," they warned.

Elsewhere, NCT Ireland recently revealed a number of other little known visual reasons your car could fail the NCT.

The NCT says: "Taking a few minutes to check some of the visual items below and ensuring they are all working in advance of your NCT could potentially save you valuable time and money."

One of the more obscure items that you could easily forget to check is the little bulbs on your registration plates. It is a legal requirement that your registration is visible at all times and if these bulbs aren't working, it cannot be seen at night.

Your car could fail its NCT if its registration plate lamps are "not working, faulty or not fitted; not white in colour; or if the lens is missing or broken." You can check these bulbs by turning your car on and checking the bulbs are on front and rear before the test.
