Abstract

This study investigated a screening method for assessing driving ability in participants aged ≥65 years, focusing on physical function, specifically handgrip strength (HGS). Quantitative validation analysis revealed a negative correlation between HGS and age and a weak positive correlation between rate of change in HGS and driving simulator score change. The accident rate was slightly higher among individuals with low HGS, though further validation is necessary. Additionally, qualitative validation highlighted individual differences influenced by exercise frequency and social participation. Consequently, we recommend that evaluation methods consider these individual variations, especially when assessing driving ability in individuals with lower HGS.
