examination of the relationship between passenger, driver, and situational characteristics in fatal crashes
abstract
both the youngest and oldest drivers in our society are overrepresented amongst fatal
crashes. as such, there is a need for prevention strategies which may reduce crashes in
each cohort. passenger presence is one factor that has been shown to be both an
obstruction and an aid in reducing fatal crashes. this study aimed at determining which
types of passenger characteristics and driving conditions benefited either teen (16-19
years of age) or elderly drivers (65 years of age or older). the effects of passengers in
fatal crashes in the pars database through 1975-2003 were examined. results showed
that whether a passenger was useful for various age groups differed for driving
circumstances both inside and outside of the vehicle. overall elderly and middle age
drivers experienced a protective effect for the presence of a passenger whereas teen
drivers experienced an increase risk for unsafe driving behaviours when a passenger was
present. an analysis of gender and age of both passenger and driver suggested that the
relationship of these variables might be an important consideration. it was also found
that certain situational variables such as weather and time of day may moderate the
degree to which a passenger is effective. implications of these findings are discussed.
