Abstract

One of the most popular coactive measures developed to prevent road traffic accidents in recent decades is the implementation of driving licenses based on points systems (PS) which penalize repeat offenders with suspension or withdrawal of their licenses. This paper analyzes their rapid spread worldwide through an in-depth review of the existing literature. A comprehensive meta-analysis of the effects of PS on road traffic accidents and the duration of these effects has been conducted. The findings show that the strong initial positive impact (15 to 20% reductions in accidents, fatalities and injuries) seems to wear off in under eighteen months. This limited effectiveness is related to the absence of complementary enforcement to back up these measures. Without them, points systems could turn into a boomerang road safety policy, and even be abandoned at a later date. The implications of the conclusions for legislation and future research are considered.
