According to statistics, drunk drivers who repeatedly violate the DUI (Driving under influence) regulation have been continuously increased, and now the habitual drunk drivers become a societal problem. Employing a confirmative factorial analysis of structural equation model to analysis psychological characteristics of habitual drunk drivers and also seek countermeasures, this study identify the difference among three different groups of drivers: 1) sober drivers, 2) drivers with a DUI violation record, and 3) drivers with more than two records. The results of this study are as follows: First, remedies and educational contents to rectify drunk drivers can be differentiated according to their drunk driving records. Second, using defense mechanism (e.g., rationalization, projection, sublimation), drunk driving psychology (such e.g., sense of guilt, shame, embarrassment) and self-esteem (e.g., affirmation, denial) as theory variables, a Structural Equation is constructed to represent Psychological Characteristics of drunk driving according to records on drunk driving. Third, as a result of analysis of the Psychological Characteristics Model, measures for prevention and reduction of drunk driving suitable for the characteristics of respective group are also suggested. Forth, drunk driving measures based on drinking individuality are complemented by concurrence analysis on records of drunk driving records and National Alcoholism Screening Test (NAST) score. Also, two or more times recorded drunk drivers are classified as inveterate drunk drivers.

This paper investigated habitual drunk drivers' characteristics by grouping them by the number of DUI records, and customized countermeasures for each group. Theoretical models to accommodate underlying causes for drunk driving, which adopted the form of a path analysis, were developed based on psychological variables. According to the psychological paths to drunk driving, each group showed different defense mechanisms and different senses of guilty, shame and embarrassment. This provided a rationale for differentiating countermeasures for each group. Habitual drunk drivers were found to have a strong propensity of self-justification due to their defense mechanism. Thereby, it would be useless to simply discourage them from drinking and driving. Rather, more active measures such as locking devices, invalidation of driver license, and group counseling should be taken to stop habitual drunk driving. Furthermore, since habitual drunk drivers showed high projection propensity, it is necessary to force them to participate in a sensibility training program, which might entail the amendment of related laws or regulations.
