Former Miss Ireland Aoife Walsh has said that her NCT slip "could have happened to anyone".
The beauty queen (25) was stopped by gardai at Oola, Co Limerick, on April 17 this year and an inspection showed she was not displaying a current NCT disc.
She was fined €150 for the offence in Limerick District Court and given four weeks to pay it.
Aoife, who has three third-level degrees - Arts from UCC, a Masters in Business Management from University of Limerick and a postgraduate degree from Trinity College Dublin - told the Herald that not having an NCT disk on her car was "just one of those things".
"It happened to me and it could have happened to anyone," she said. "It's all sorted now and what can you do? It just happened to also be in the paper. I'm not the first person it happened to and I'm not going to be the last, it's just a pity," she added.
The Clonmel native is the second beauty queen to be fined for motoring offences recently. Former Miss Limerick Gemma Reilly was fined €500 at the start of October after pleading guilty to speeding.
Gemma made the headlines when she pleaded guilty to speeding at 187kph in a 120kph zone on the Ennis to Gort motorway on March 3.
