Digital clock drawing test reflects visuospatial ability of older drivers.

Objectives: To keep older drivers safe, it is necessary to assess their fitness to drive. 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.

Methods: One hundred and forty-one community-dwelling older drivers (range; 64-88 years old) who participated in this study were included in the analysis.
