CINCINNATI -- Teenagers are often considered the most dangerous drivers, but Cincinnatti television station WLWT found out that there's another hazardous age group -- senior citizens.

In one Ohio county, older drivers are at fault in accidents at almost as high a rate as teens -- nearly 60 percent of the time, compared to 62 percent for teens.

The station went out on several afternoons and followed some older drivers. The drivers didn't know a reporter was following them, so that they wouldn't be nervous about being on camera.

One man was found weaving and swerving out of his lane. The man stopped where there isn't a stop sign and then blew through an intersection where he was supposed to stop. Several times, the man turned from the center lane of the road instead of from the turning lane.

A reporter followed the man, Charlie, back to his house to ask him about his driving. He said he's either 96 or 98 years old -- he can't remember. He also said he can't remember when he took a driving test, but he said he only ventures out a couple times a week, not straying far from home.

"My eyesight is going down," Charlie said.

Another older man, Tony Schmutte, wobbled in his lane and made a right on red when he wasn't supposed to. Then he pulled out in front of a fire engine and another car, which nearly hit him.

"My wife tells me I drive lousy since I'm getting older," Schmutte said.

Not only are spouses concerned about older drivers' safety, but many adult children also say they worry about their parents on the road.

"I worry should they miss a stop sign or go through a red light, should he not be able tell if it's red, a pedestrian's life could be in danger," Pat Pearson said.

Though it might mean less independence, Pearson said she wants her parents to stop driving.

"He can't see," she said. "I think my father feels like his life would be over if his keys were taken from him."

"We can't have somebody sitting out there in a car waiting to go on our errands and we don't drive a long way," said Arlene Pearson, Pat's mother. "We know better than to do that."

But research shows the risk of older drivers being involved in an accident increases for every mile they drive. If they are in a crash, the rate of fatalities increases significantly after the age of 75.

Nancy Chandler lost her husband, Frank, two years ago after he was killed by an 84-year-old driver who, just a week earlier, had been in another crash.

"Anybody who met Frank fell in love with him," she said. "For me it's just a void I'll never be able to fill. I sympathize with the elderly. I don't know what I could possibly say to them, except to think of their own families."

More than 20 states have requirements for older drivers. New Hampshire and Illinois require road tests for those 75 and older. In Nevada, drivers 70 and older who renew licenses by mail must include a medical report.

Ohio and Indiana require eye exams when drivers renew their licenses, but nothing else. And in Kentucky, drivers don't even have to take an eye exam as they get older -- as long as drivers renew their licenses on time, they may never have to take another vision or driving test no matter how old they are.

Chandler said she's pleaded with Kentucky lawmakers plan to toughen state laws on older drivers, but all she has received is a letter stating that Kentucky law prohibits targeting anyone for retesting based solely on age.

Faced with evidence of the danger they pose on the roads, the older drivers the station spoke with said they still wouldn't put down their keys.

"I wouldn't want somebody hauling me around all the time," Schmutte said.
