RESUMO
OBJECTIVES: Around the world, aging populations pose significant concerns regarding their community mobility and transportation safety. Most previous studies in the United States have focused on the associations between driver license renewal laws and crash outcomes among older adults (65 years and older). Few studies have evaluated the impact of driver license renewal laws on older adults' community mobility. This study aimed to identify the associations between driver license renewal laws and older males' and females' daily driving likelihood and duration. METHOD: The 2003-2017 American Time Use Survey data were merged with driver license renewal legislation using ages 55-64 to control for effects of non-licensure factors (e.g., gasoline price). Weighted Poisson and linear regression models were used to estimate the associations of various driver licensure provisions with older males' and females' daily driving likelihood and duration. RESULTS: A shorter in-person renewal period and the presence of mandatory reporting laws for physicians were associated with a lower daily driving likelihood and shorter driving duration among females aged 75 years or older. The presence of mandatory reporting laws was also associated with reduced daily driving likelihood and duration for males aged 65-74 years. DISCUSSION: Policymakers should be aware that males and females may respond differently to older driver licensure laws, which may require distinct interventions to preserve their mobility. Future studies should consider the gender disparities when examining the association between driver licensure policies and older adults' transportation safety and mobility.
