Without so much as a tap on the brakes, my aunt whizzed through another stop sign.

"What are you doing?" I shrieked. "That was a stop sign."

"Oh," she replied rather offhandedly, "they just put those there so you'll look before you go into an intersection."

That was the day I stopped riding with my aunt but not the day she stopped driving. From then on, I had visions of an enormous pink Chevy leading a parade of cascading accidents. And I wasn't far from wrong.

She drove with what she knew to be the utmost caution. . . .never exceeding 30 miles per hour, even on I35! She expected, even demanded that traffic would give way to her like the seas parted for Moses. Sometimes, it did. But mostly, driving with her was a harrowing experience with no end in sight.

So, when do the elderly become a menace on the roads? And, what can you do when they refuse to give up the keys? Here are a few suggestions I've found.

Causes for Concern

Poor Vision - Cataracts, glaucoma, and macular degeneration can reduce visual acuity and limit visual fields, so a yearly eye exam is imperative for the elderly driver. Ask the doctor about driving, and don't take the word of the elderly driver on the results of her exam.

Poor Hearing - Something as simple as a clogged ear passage can create a hearing loss. A doctor can identify the problem and offer solutions, so have elderly hearing checked yearly.

Poor Flexibility and Limited Range of Motion - Good drivers rely on looking out rear and side windows as well as checking rearview mirrors. When a driver lacks the ability to turn his head and shoulders to look outside, he may not see oncoming vehicles or obstacles traveling in the car's blindspot.

Reduced Reaction Time - As we age, we slow down, and reaction times diminish. Keeping extra space between the driver's and other cars can help reduce the likelihood of accidents, but there comes a time when reactions are too slow for road safety.

How to Get (and Keep) the Keys

A few states, , require road tests for persons over 65 when their licenses are renewed. An additional states require vision tests with license renewals. Consider yourself fortunate if you live in one of these states because it may be that the state will refuse to renew the elder's license. If you live elsewhere, here are a few tricks to try.

Talk with your Elder about the Convenience of Mass Transit - Many mass transit authorities have special services and special fares for the elderly and disabled. Check with your local transit authority. And talk with your elder about how nice it is to be able to enjoy the scenery while someone else does the driving.

Give Your Elder a Refresher Course - Not only will a refresher course improve road awareness, it may help your elder earn a discount on his car insurance. Courses and informative pamphlets are available from the AARP, AAA, and the AAA Foundation for Traffic Safety. You'll find links to these sites at the end of this article.

Report unsafe driving to your local Department of Public Safety. They may have additional help to offer you.

"Break" the Car - My teenagers unplugged a few vital wires when my father, who suffers from Alzheimer's disease, refused to relinquish the keys. We knew his cognitive ability was far too impaired for him to recognize the problem, and he was always comforted when we said we'd have the car repaired "soon."

Remove the Keys - Distract your elder from finding "lost" keys by offering an immediate alternative way to go somewhere. While this may be the most unpleasant way to stop your elder from driving, remember that you are not only protecting him but all the rest of us as well.

And what happened to my aunt? She got a ticket from a wonderful traffic officer whom we all blessed on a daily basis! Fearing the loss of her auto insurance, she voluntarily gave up driving.
