The first test assesses traffic knowledge and visual comprehension via road-sign recognition, while the second measures visual-perceptual and mental speed in a compass test. Finally, a trail-marking test is used to indicate visual-motor tracking and visual scanning abilities. If the individual being evaluated scores below 8.5/12 points on the first evaluation, 25/32 points on the second or takes more than 90 seconds on the trail-marking examination, chances are he or she would fail a road test.
The study was published in the journal of the American Academy of Neurology and included information from 30 previous trials. A total of 1,728 stroke victims with an average age of 61 were involved in the research.
