Shared responsibility is an increasingly important part of the road safety programme, as evidenced most recently with the hugely successful Ghost Chips campaign, which, for the first time, specifically targeted young Maori and used humour to equip them with the tools required to speak up when one of their mates was too drunk to drive. And NZTA, Clemenger BBDO and The Sweet Shop have followed up that pop cultural phenomenon with a new campaign that tries to convince family members to do the same.
