Therefore, the study will provide another direction toward a specific target group of victims whom policy makers and development partners are trying to combat for in order to achieve that national strategy.
Finally, also contribute to the Theory of Planned Behavior (TPB) for which previous studies were using this TPB to study in other fields rather than in the field of alcohol use drink-driving behaviors. Meanwhile, an addition of moral norms to the original the TPB will also bring a new measurement and predictor to the theory for future prediction of other fields.
