Motorbike Driver's Decision Models for Drinking and Driving Behavior

Abstract

Drinking alcohol reduces driver's ability to do safely and increases risks of crashes. Behavioral models were applied and developed to understand the driver's decision for drinking and driving (DAD) behavior. Theory of Planned Behavior model, Health Belief model and Integrated Behavior model were included then Integrated Behavior model was proved to be the best model for predicting both intentions and behavior of DAD. The most significant factors of the driver's decision models were subjective norm, affective attitude and behavioral intention. These findings could help the local authority to propose factors for proper intervention programs and policies in order to minimize efficiently the DAD behavior of drivers.
