SummaryQuestion
What is the effect of driver's licence renewal policies on the fatality rate among elderly drivers?Study design
Retrospective cohort study.Main results
In-person licence renewal significantly reduced the overall and daytime risk of fatality in drivers aged 85 years or over, but did not reduce fatality in the younger elderly (65 to 84 years; see Results table. The use of vision tests, road tests, or shorter renewal periods did not significantly affect the risk of daytime fatality in any elderly age group after adjustment for within-state confounding factors (see Results table).Authors' conclusions
In-person licence renewal significantly reduced fatalities among elderly drivers, but only those aged 85 years or older. Shorter licence renewal periods and vision tests or road tests at renewal did not reduce fatalities among elderly drivers (aged 65 years and over). |
