The study examines whether the use of various tests of vision and cognitiv functioning can identify elderly drivers with reduced ability to drive safely in traffic. The driving skills of 88 elderly drivers were evaluated, and the drivers also completed various tests of vision and cognitive functioning. A combination of four simple tests predicted 78 % of the drivers who were regarded to represent a danger to either themself or to others in traffic. These included: reduced acuity under glare conditions, defects in the central field of vision, cognitive impairments/dementia, and impaired attention. None of these tests are included in the medical examination elderly drivers have to complete today.
