TfL’s ‘One Risk’ campaign targets unsafe behaviours on the road, like looking at your phone, or going too fast.

If you ask someone if they speed, or look at their phone while driving, they rarely honestly say they have never done it. The usual response is ‘I hardly ever do it.’ They understand that the behaviour is wrong, but still do it ‘the odd time,’ and rationalise that their chances of having an accident are low.

We make over 35,000 decisions every day. Most of them without thinking. But just one bad decision on the road can be fatal. This individual advert successfully dramatizes the idea of 'One', and links insignificant snap decisions with their disastrous consequences.
