Many drivers deliberately break traffic laws both because they are convinced that there is little chance of getting caught and because even if they are caught, the penalties do not act as a sufficient deterrent. For example, people who would never think of stealing money, even when they needed it, think nothing of routinely exceeding a 30mph limit, even in a street where children are playing. It is clear, then, that a substantial reduction in road accidents can be achieved only by catching more motorists who break the law and by increasing the penalties for such lawbreakers.
