We developed a touch screen-based digital Clock Drawing Test (dCDT) and examined the relationship between the dCDT scores and on-road driving performance of older drivers in a community-setting.<h4>Methods</h4>One hundred and forty-one community-dwelling older drivers (range; 64-88 years old) who participated in this study were included in the analysis. Participants completed the dCDT, the Mini-Mental State Examination-Japanese (MMSE-J), and an on-road driving assessment. We examined the relationship between dCDT scores using the method by Rouleau et al. (maximum 10 points) and the on-road driving performance based on a driving assessment system originally developed by Nagoya University.<h4>Results</h4>Multiple regression analyses showed that errors in the driving test were associated with dCDT score for the items "confirmation," "turning left" and "maintains driving lane position".<h4>Discussion</h4>This study confirmed the relationship between the dCDT score and driving errors, such as confirmation, turning left and maintaining driving lane position. The increase in these errors indicates a decline in visuospatial ability while driving. The dCDT score may reflect older drivers' visuospatial abilities while driving.Frontiers in psychology1332118https://www.ebi.ac.uk/biostudies/studies/S-EPMC10925675biostudies-literatureDigital clock drawing test reflects visuospatial ability of older drivers.PMC10925675Kawano NYamauchi SShimazaki KKojima MAoki HShinkai HShinohara KfalseDigital clock drawing test reflects visuospatial ability of older drivers.<h4>Objectives</h4>To keep older drivers safe, it is necessary to assess their fitness to drive.
