The authors review the literature pertaining to the roles of
psychopathology and personality variables in traffic accidents. They review
studies of nonpsychiatric and psychiatric samples and examine the roles of
suicide, life events, alcohol, and drugs. Certain personality
characteristics and psychopathology--such as low tension tolerance,
immaturity, personality disorder, and paranoid conditions-- appear to be
risk factors for traffic accidents. Although the role of alcohol is
relatively well established, the roles of most other drugs are less clear.
The results of further investigation of psychopathology's role in traffic
accidents may have implications for prevention.
