What has the impact been of roadside signs designed to make drivers sit up and improve their driving habits.

The now familiar slogans include ‘Drink Don’t Drive’, ‘Speed Kills’ and ‘A Little Care Gets You There’. The brains behind this roadside propaganda war, is the National Road Safety Association, an independent body working to the Department of Local Government.

Noel Kelly director of the National Road Safety Association explains the thinking process behind the slogans and why the emphasis is on targeting drink driving. Earlier roadside slogans used the word drink, but now the less socially accepted word alcohol is used to drive the point home.

The real enemy is the word alcohol, because it is alcohol that affects the driving performance, it is alcohol that causes the accidents.

The slogans are changed every six weeks to two months so that every motorist gets an opportunity to see the signs before they are presented with a new message.
