The campaign, created by Leo Burnett, aims to drive down child road casualties by reminding parents that "kids do as you do, not as you say" and educating them about the dangers that children face on the roads.
The Copycat campaign launches in Sunday newspapers on October 14, followed by ads in national dailies and magazines, as well as online and radio work.
The print shows various descriptions of bad behaviour copied in children's handwriting, while on the radio you hear a child copying its parent's words.
The online work, created by Weapon 7, continues the theme with a range of executions including one which features a child's handwriting copying whatever gets typed into the search engine.
As part of the campaign child psychologist Ruth Coppard will be on hand at a special training day to explain to parents how their behaviour influences their children.
At the training day parents will be invited to see the road from a child's point of view by using a giant version of a zebra crossing surrounded by oversized cars and amplified street noise.
Jim Fitzpatrick, road safety minister, said: "We can all fall into bad habits, but it's important parents realise it's no good teaching kids good road safety techniques if you don't follow them. If parents are crossing the road when the red man is showing, or not using seatbelts, then their children will copy them."
