Driving is a complicated task. It requires people to see and hear clearly; pay close attention to other cars, traffic signs and signals, and pedestrians; and react quickly to events. Drivers must be able to accurately judge distances and speeds and monitor movement on both sides as well in front of them.
It’s common for people to have declines in visual, cognitive or physical abilities as they get older. As a result, older drivers are more likely than younger ones to have trouble in certain situations, including making left turns, changing lanes and navigating through intersections.Download
