Albany N.Y. (AP) -- Of New York's 11.2 million licensed drivers, 4.5 percent, or 500,000, were over the age of 80 last year.
That group was involved in only 2 percent or 11,000 of accidents statewide the year before, though they did make up 5 percent of the drivers in fatal crashes.
More older drivers are on the road than ever before, and a review by The Associated Press found they face a hodgepodge of state licensing laws that reflect scientific uncertainty and public anxiety over a growing question: How can we tell if it's time to give up the keys?
New York licenses, valid up to eight years, have no special blanket conditions for seniors.
A vision test is required for renewals and the Department of Motor Vehicles can, on "reasonable grounds," re-evaluate drivers whose skills and abilities are in doubt.
