The more pertinent driver record trends evidenced by age, sex and marital status data indicate that accidents and citations tend to decrease with age, except at extremely old ages. Both married and single female drivers had driving records that were markedly superior to those of their respective male counterparts. Relative to both citation and accident frequency, the greatest similarity between males and females involved the married male-single female comparisons. Driving record differences with respect to sex tended to decrease with age. For most age, sex and marital status comparisons, driver record differences with respect to citations were greater than differences with respect to accidents. Regardless of the effects of other uncontrolled variables, the tabulated accident and citation frequencies presented herein represent the absolute frequency of accident and violation occurrence relative to any given age by sex by marital status stratification. Thus, a statistical profile is presented of considerable predictive and practical significance.
