As the population in most developed countries continues to age, there is an increasing concern about its effect on traffic safety, resulting in calls to tighten the licensing renewal policies for mature drivers. This study examines the licensing requirements in five Canadian provinces and their respective vehicle collision rates for ageing drivers. Contrary to expectation, we find a positive correlation between the stringency of the licensing system and the mean crash rates. Therefore, increasing the mandatory testing and licensing requirements is not recommended at this time.
