The present study was designed to improve our understanding of Turkish drivers' perceptions of driving after the use of alcohol. The data of drinking driving characteristics and habits was obtained through a survey. Alcohol-related driving attitudes were obtained by developing a questionnaire using the Theory of Planned Behavior - TPB (Ajzen, 1985). This questionnaire included both globally and belief based measures of TPB constructs. Five hundred and fifty participants, who had a valid driving license with a driving experience of minimum 12 months, drank alcohol occasionally, and living in the Izmir provincial area completed the questionnaire. Regression analysis of the globally measured (52 %) and belief based (47 %) model of the TPB revealed strong relationships between the TPB determinants and intention to drink and drive. Perceived behavioral control made the largest contribution to both belief based and globally measured models. Male and young drivers perceived the outcomes of drunk driving as less negative, felt less disapproval, and less in control of drinking and driving behavior. Furthermore, drivers with higher frequency of drunk driving were observed to have more positive attitudes, lower subjective norms and lower behavioral control over drunk driving.
