Driving Evaluation and Fitness for Persons With Cognitive Impairments

"The participants completed the actual driving with a licensed driving instructor on the passenger side in the car and with a dual-control, automatic-transmission car.~Each participant completed three runs of the same route. The first twos were practices to familiarize themselves with the course. The driving instructor graded them on the third run. Each trial took about 10 minutes. The participants were scored according to governmental driver test guidelines. Scoring on individual driving maneuver is weighted. Depending on the type of error, 8, 16 or 32 points were deducted from 100, for example, 32 points for getting too close to pedestrian lane, running a red light or railroad crossing, and 8 points for stopping in S-curve forward and backward. 70 or above is considered as a pass. The occupational therapists in the backseat recorded driving behaviors, including whether the driver checked rear and side mirrors, excessive sweating, distractibility, number of adjustments, etc."
