My dad got his license back a few months ago after having his stroke a little over a year ago. He had to be retested and had madifications done to his car in order for him to drive it. Because he only has the use of one arm he now has a knob on the steering wheel for turning (like the truckers use) and a modification on his turning signals that lets him use his right hand to signal.

Before the stroke my father had a class one license, which in Alberta is the highest class you can get, it meant he could drive anything from an emergency vehicle to a motorcycle and he did it quiet well. On his retest the tester informed my father that he drives better then quite a few people with the use of both hands.

I'm not saying that my father is a perfect driver, now he is far from it, he forgets to signal at times, drifts a little bit while in the lane and other little things like that. But the only time he drives is in the city my mother will not let him drive on long trips.
