Department for Transport 'moment of doubt' by Leo Burnett

The Department of Transport's latest campaign in its fight to prevent drink driving shows the devastating personal consequences drivers can experience if they are stopped on the road and breathalised.

The 30-second TV spot, created by Leo Burnett, is filmed from the point of view of a male drinker as he approaches a bar, with the camera offering the viewer a first-hand account of the man's experience as he begins to order a drink.

But before he can tell the barman his order, the barman eerily takes on the voices of a range of characters, including a policeman, his boss, a car salesman and a distressed girlfriend.

Each character gives the viewer and the man an insight into their reaction if he was convicted for drink driving. The impressive ad is supported by ambient, radio and online activity.
