Recent developments in our understanding of decision-making processes in complex or natural environments are yet to be applied fully in the road-user behaviour context. This paper discusses the possibility that recent psychological models of decision making may be a useful addition to the deterrence model generally used to account for the effect of enforcement on drink-driving behaviour, potentially displacing rational decision-making models that are usually applied in this context. Recent evidence from a number of Monash University Accident Research Centre projects bearing on this issue is discussed. It is concluded that continued reliance on rational decision-making models as an explanation and a guide for countermeasure development is likely to be unproductive, and that there are substantial advantages to be had from considering the effects of enforcement terms of natural decision making models.
