Large signs of Mrs Doyle - the character played by Pauline McLynn who played the character in the iconic Fr Ted series - are being erected across Co Mayo once again this week, to remind drivers and motorcyclists to freshen up by taking a break, and to think about the consequences of driving while tired.
The initiative is being organised by the Mayo County Council Road Safety office in association with the Gardai, ahead of the busy August Bank Holiday weekend.
The campaign is called "Go On, Go On, Take A Break" - and some of the road signs of Mrs Doyle will be located at or near some Corrib Oil service stations.
Mayo Road Safety Officer Noel Gibbons says the August Bank Holiday weekend is one of the busiest and deadliest weekends on Ireland's roads, and he says he cannot underestimate the importance of stopping for a break for a cup of tea or coffee, as fatigue is a serios killer.
He's urging motorists to take regular breaks when driving long distances, share driving where possible, and never ignore the warning signs of fatigue.
